AB  - Despite presenting a practical approach for the characterization of the environmental risk of potentially toxic elements (PTEs) derived from steel production facilities, the analysis of the spatial distribution of bioavailable PTEs concentrations in the soil is frequently overlooked in the management of polluted sites. In this study, the diethylenetriaminepentaacetic acid (DTPA)-extractable forms of PTEs were investigated in soils surrounding the largest Serbian steel production plant. The correlation and geostatistical analysis indicated their pronounced variability suggesting the anthropogenic origin of most investigated elements, apparently from the steel production facility. The detailed visualization of variables and observations derived by self-organizing maps (SOMs) revealed the homologies in PTEs’ distribution patterns, implying the common origin of some elements. These observations were confirmed by principal component analysis (PCA) and positive matrix factorization (PMF). The аpplied approach supports a comprehensive assessment of contaminated sites' ecological and health risks and provides a basis for soil remediation.

AB  - Gully erosion leads to the formation of deep and wide channels that increase the risk of soil loss, flooding, and
water pollution. In addition, this process reduces the productivity and viability of agricultural land and natural
ecosystems. Preventing gully erosion is critical for maintaining ecological balance and preserving natural resources in certain areas. This paper presents a methodology integrating remote sensing and nuclear techniques to
study gully erosion. The morphometric characterization of gullies using 360-degree camera photogrammetry was
introduced as a new method in erosion research. This approach aims to investigate the suitability of unmanned
aerial vehicle and terrestrial photogrammetry for modeling gullies, to study the variability of erosion processes in
gullies at a small scale, and to compare the differences in erosion intensity between nearby gullies. The study’s
objectives include identifying the effective and economical method for gullies monitoring and providing a
starting point for controlling and safeguarding gullies. Mainly erosion process was detected in the studied gullies,
while deposition was identified at only 2 out of 39 sampling locations. The results showed an average soil
redistribution rate of 16.2 t ha− 1 yr− 1 and coefficients of variation of 32%, 59%, and 91% for three investigated
gullies. It was determined that aerial photogrammetry methods were not practical under the conditions prevailing in the study area. Highly detailed 3D models of the gullies were created using 360-degree photogrammetry. It was confirmed that the micro-relief obtained by photogrammetric modeling is an essential contribution
to erosion research. The 360-degree camera photogrammetry serves as a reliable tool for analyzing the
morphology of gullies and, in perspective, tracking changes in gully systems over time or monitoring the
effectiveness of the applied protection measures.

AB  - The gully erosion is one of the most significant land degradation processes. Although gully erosion significantly threatens agricultural productivity and natural ecosystems, European land management strategies frequently need more reliable data on environmental conditions governing this process. This study presents a methodology that integrates remote sensing and nuclear techniques for examining gully erosion (Đokić et al., 2023). It introduces a novel approach to erosion research by employing 360-degree camera photogrammetry to characterize gullies morphometrically. The main objectives of this approach are to evaluate the applicability of unmanned aerial vehicles and terrestrial photogrammetry for modeling gullies, to study small-scale erosion processes within gullies, compare erosion intensity between adjacent gullies, and determine the most effective and cost-efficient method for monitoring gullies. A total of 39 soil samples were taken in three studied gullies. The results revealed an average soil redistribution rate of 16.2 t ha−1 yr−1 and coefficients of variation of 32%, 59%, and 91% for the gullies. The estimated erosion rate varies from a minimum of 0.1 t ha−1 yr−1 to a maximum of 34.3 t ha−1 yr−1. Soil deposition was identified at only two sampling sites, 1.1 and 2 t ha−1 yr−1. Highly detailed 3D models of the gullies were created using 360-degree photogrammetry. The micro-relief obtained through modeling proved to be an essential aspect of advanced erosion research.

AB  - Hilly terrains characterized by the looseness of the surface soil layer and the slope of the topographic surface are subjected to diverse erosion processes, which could greatly impact forest management. An erosive process was identified along the unstable slopes in most of the Crveni potok catchment in the southeastern part of Serbia. The results of this study indicate two erosion types of variable intensity, dominated by weak and moderate erosion, while severe erosion is identified at several locations. Water pressure in the pores of loose soil in the Crveni potok catchment generates gully erosion in parts of the catchment that are geologically predisposed by the composition of the parent substrate. The paper discusses the factors influencing gully erosion, such as soil density, the slope of the topographic surface, rainfall (precipitation amount, annual distribution), and vegetation characteristics. The set of used methodologies, including remote sensing, nuclear, and geospatial ones, provided an integrated assessment of factors affecting erosion in unstable forest areas. The soil erosion rates in the study area are estimated from inventories of fallout radionuclide 137 Cs using conversion models. Airborne photogrammetry, terrestrial Structure-from-Motion 360-degree camera photogrammetry, and Terrestrial LiDAR Scanning (TLS) are used to model complex geomorphological features of forest terrain. These techniques are found to be convenient for the quantification of the existing state of erosion (length, width, volume, and density of the gully systems) in the forest gullies. The remote sensing techniques provided an insight into the physiographic characteristics of the studied area important for determining its parts affected by erosion. The models obtained using different techniques are compared, techniques are evaluated, and their advantages and disadvantages are pointed out. This approach enables the identification of priority targets for soil conservation and site-specific remediation measures to foster sustainable forest management.

AB  - As an inert radioactive gas, 222Rn could be easily transported to the atmosphere via emanation, migration, or exhalation. Research measurements pointed out that 222Rn activity concentration changes during the winter and summer months, as well as during wet and dry season periods. Changes in radon concentration can affect the atmospheric electric field. At the boundary layer near the ground, short-lived daughters of 222Rn can be used as natural tracers in the atmosphere. In this work, factors controlling 222Rn pathways in the environment and its levels in soil gas and outdoor air are summarized. 222Rn has a short half-life of 3.82 days, but the dose rate due to radon and its radioactive progeny could be significant to the living beings. Epidemiological studies on humans pointed out that up to 14% of lung cancers are induced by exposure to low and moderate concentrations of radon. Animals that breed in ground holes have been exposed to the higher doses due to radiation present in soil air. During the years, different dose-effect models are developed for risk assessment on human and non-human biota. In this work are reviewed research results of 222Rn exposure of human and non-human biota. © 2020, ISB.

AB  - Radioactive materials released during the two most serious nuclear accidents in history, at Chernobyl and Fukushima, caused exceptionally significant contamination and perturbations of the environment. Among them, this paper focuses on the effects related to the atmospheric electricity (AE). Measurements of the most significant disturbances in the values of various AE parameters recorded near ground level are reviewed and the corresponding results are jointly evaluated. The Chernobyl and Fukushima events caused changes in the AE parameters both after long-distance transport (Chernobyl) and short-distance transport including re-suspension (Fukushima). The data indicates that the electrical conductivity of the air is more sensitive to the presence of airborne radioactivity than the atmospheric electric potential gradient (PG). PG, on the other hand, can be monitored more easily and its variation also reflects the vertical redistribution of radionuclides in the air due to their transport, deposition, and re-suspension from the ground. A brief overview of studies on atmospheric transport and deposition of radioactive clouds is given to facilitate the importance of considering the AE measurements in these subjects, and to incorporate those studies in interpreting the results of AE measurements. The AE measurements are particularly important in studying microphysical effects of enhanced radioactivity in the air where no other distance monitoring method exists, both for fair weather conditions wet conditions.

abstract = "Radioactive materials released during the two most serious nuclear accidents in history, at Chernobyl and Fukushima, caused exceptionally significant contamination and perturbations of the environment. Among them, this paper focuses on the effects related to the atmospheric electricity (AE). Measurements of the most significant disturbances in the values of various AE parameters recorded near ground level are reviewed and the corresponding results are jointly evaluated. The Chernobyl and Fukushima events caused changes in the AE parameters both after long-distance transport (Chernobyl) and short-distance transport including re-suspension (Fukushima). The data indicates that the electrical conductivity of the air is more sensitive to the presence of airborne radioactivity than the atmospheric electric potential gradient (PG). PG, on the other hand, can be monitored more easily and its variation also reflects the vertical redistribution of radionuclides in the air due to their transport, deposition, and re-suspension from the ground. A brief overview of studies on atmospheric transport and deposition of radioactive clouds is given to facilitate the importance of considering the AE measurements in these subjects, and to incorporate those studies in interpreting the results of AE measurements. The AE measurements are particularly important in studying microphysical effects of enhanced radioactivity in the air where no other distance monitoring method exists, both for fair weather conditions wet conditions.",

AB  - This study was conducted to compare soil particle density (ρs), soil total porosity (TP), liquid limit (LL), plastic limit (PL), and plasticity index, and their relations with soil organic matter (SOM), of non-carbonate silty clay Fluvisols under different land uses. Three neighboring land uses were studied: native deciduous forest, arable land, and meadow, managed in the same way for more than 100 years. Soil was collected from 27 soil profiles and from three depths (0–15, 15–30 and 30–45 cm). Land use caused statistically significant but different impacts on soil properties, particularly in the topsoil. The forest topsoil measured the lowest ρs and bulk density (ρb) but the highest SOM and soil water content at PL, compared to meadow and arable soil. Statistically significant linear relationship was observed with the SOM content and ρs (− 0.851**), ρb (− 0.567**), calculated TP (0.567**) and measured TP (− 0.280**). There was a nonlinear relationship between SOM and LL (0.704**) and PL (0.845**) at the topsoil. The findings suggested that SOM content strongly affected ρs, ρb, TP, LL and LP. This regional study showed that the conversion of forestland into agricultural land without appropriate measures to conserve SOM leads to the degradation of physical and rheological soil properties.

AB  - The main focus of this study was to assess radiation exposure to human and non-human biota due to natural radionuclides in soil of the Serbian capital. For the first time, ERICA tool was employed for calculation of gamma dose rates to non-human biota in this area. In analyzed soils, the mean values of Ra-226, Th-232 and K-40 specific activities were found to be 35, 43 and 490 Bq kg(-1), respectively. The distribution of analyzed natural radionuclides in soils was discussed in respect to its statistically significant correlations with sand, silt, clay, carbonates, cation exchange capacity and pH value. The annual outdoor effective dose rates to the population varied from 48 to 98 mu Sv, and the total dose rates to terrestrial biota, calculated by ERICA tool, varied from 9.84 x 10(-2) mu Gy h(-1) (for tree) to 5.54 x 10(+0) mu Gy h(-1) (for lichen and bryophytes). The results obtained could serve as a baseline data for the assessment of possible anthropogenic enhancement of the total dose rate to human and non-human biota of the study area.

AB  - Anthropogenic activities may lead to increased levels of heavy metals in soil environment and to reduced environmental quality. In this study concentrations of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn) were measured by using an atomic absorption spectrometer and soil samples were collected in the vicinity of the largest coal fired power plant in Serbia. The soil pollution status was assessed and enrichment by heavy metals at some sampling sites was revealed. For investigated metals the enrichment factors were in the range of 0.3 to 15.5, while the mean values indicated deficient to minimal enrichment of heavy metals in the investigated area. The highest contamination factor was determined for Ni, followed by Zn, Co and Cd. Cluster analysis was used to identify associations between heavy metals and soil properties. Significant positive correlations were found between: (1) Cd and Mn, Ni, Pb, Zn; (2) Cr and Cu, Fe, Ni, Pb; (3) Zn and Cu, Ni, Pb; and (4) Fe and V. Spatial distribution maps of heavy metal contents based on geostatistical analysis indicated similar patterns of spatial distribution for Co, Fe and V as well as for Cd, Mn, Ni and Pb. The hot spots for Co, Cr, Cu and Zn were revealed between two blocks of coal fired power plant in the investigated area. The distribution pattern revealed that the highest concentrations matched the predominant wind directions. It may be concluded that operation of the coal fired power plant has no significant negative impact on the surrounding environment with regard to the content of investigated heavy metals.

AB  - Anthropogenic activities may lead to increased levels of heavy metals in soil environment and to reduced environmental quality. In this study concentrations of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn) were measured by using an atomic absorption spectrometer and soil samples were collected in the vicinity of the largest coal fired power plant in Serbia. The soil pollution status was assessed and enrichment by heavy metals at some sampling sites was revealed. For investigated metals the enrichment factors were in the range of 0.3 to 15.5, while the mean values indicated deficient to minimal enrichment of heavy metals in the investigated area. The highest contamination factor was determined for Ni, followed by Zn, Co and Cd. Cluster analysis was used to identify associations between heavy metals and soil properties. Significant positive correlations were found between: (1) Cd and Mn, Ni, Pb, Zn; (2) Cr and Cu, Fe, Ni, Pb; (3) Zn and Cu, Ni, Pb; and (4) Fe and V. Spatial distribution maps of heavy metal contents based on geostatistical analysis indicated similar patterns of spatial distribution for Co, Fe and V as well as for Cd, Mn, Ni and Pb. The hot spots for Co, Cr, Cu and Zn were revealed between two blocks of coal fired power plant in the investigated area. The distribution pattern revealed that the highest concentrations matched the predominant wind directions. It may be concluded that operation of the coal fired power plant has no significant negative impact on the surrounding environment with regard to the content of investigated heavy metals.

AB  - The need for reliable assessments of soil erosion rates in Serbia has directed attention to the potential for using Cs-137 measurements to derive estimates of soil redistribution rates. Since, to date, this approach has not been applied in southeastern Serbia, a reconnaissance study was undertaken to confirm its viability. The need to take account of the occurrence of substantial Chernobyl fallout was seen as a potential problem. Samples for Cs-137 measurement were collected from a zone of uncultivated soils in the watersheds of Pcinja and South Morava Rivers, an area with known high soil erosion rates. Two theoretical conversion models, the profile distribution (PD) model and diffusion and migration (D and M) model were used to derive estimates of soil erosion and deposition rates from the Cs-137 measurements. The estimates of soil redistribution rates derived by using the PD and D and M models were found to differ substantially and this difference was ascribed to the assumptions of the simpler PD model that cause it to overestimate rates of soil loss. The results provided by the D and M model were judged to more reliable. (C) 2016 Elsevier Ltd. All rights reserved.

AB  - The area of southeastern Serbia, the Pinja and South Morava River Basins, is under the influence of very strong erosion, and the aim of this study was to investigate the vertical and spatial distribution of the Cs-137 in the eroded soils of this area. Vertical soil profiles were collected with 5-cm increments from the uppermost layer down to 20, 25, 30, 40, and 50 cm of depth, depending on the thickness of the soil layers, i.e., down to the underlying parent rocks. Measurements of Cs-137 activity concentration were performed by using the HPGe gamma-ray spectrometer ORTEC-AMETEK (34 % relative efficiency and high resolution 1.65 keV at 1.33 MeV for Co-60), from its gamma-ray line at 661.2 keV. The mean Cs-137 activity concentration across all 18 soil profiles (for all soil layers) was found to be 20 Bq kg(-1). In the greatest number of soil profiles, the Cs-137 activity concentration was generally highest in the first soil layer (0-5 cm) and decreased with soil depth, while in a few soil profiles, the peak of either the Cs-137 activity concentration occurred in the second soil layer (5-10 cm) or the Cs-137 activity concentration was almost equal throughout the entire soil profile. The mean Cs-137 activity concentration in the first soil layer (0-5 cm) was found to be 61 Bq kg(-1), and the high coefficient of variation of 92 % pointed out high spatial variability and large range of the Cs-137 activity concentrations in the study area. The obtained results indicate that in the greatest number of soil profiles, Cs-137 is present in the upper layers, with concentration decreasing with depth, as is typical in uncultivated soil. Its spatial distribution was very uneven among the surface soil layers of the investigated sites. One of the main reasons for such pattern of Cs-137 in the study area may be soil erosion. Additional investigations which would support this hypothesis are required.

AB  - Primordial radionuclides, U-238, Th-232 and K-40 were determined in soil samples collected at two depths (0-10 and 10-20 cm) in the vicinity of the largest coal-fired power plant in Serbia, and their spatial distribution was analysed using ordinary kriging. Mean values of activity concentrations for these depths were 50.7 Bq kg(-1) for U-238, 48.7 Bq kg(-1) for Th-232 and 560 Bq kg(-1) for K-40. Based on the measured activity concentrations, the radiological hazard due to naturally occurring radionuclides in soil was assessed. The value of the mean total absorbed dose rate was 76.3 nGy h(-1), which is higher than the world average. The annual effective dose due to these radionuclides ranged from 51.4 to 114.2 mu Sv. Applying cluster analysis, correlations between radionuclides and soil properties were determined. The distribution pattern of natural radionuclides in the environment surrounding the coal-fired power plant and their enrichment in soil at some sampling sites were in accordance with dispersion models of fly ash emissions. From the results obtained, it can be concluded that operation of the coal-fired power plant has no significant negative impact on the surrounding environment with regard to the content of natural radionuclides.

AB  - Among radionuclides in the soil deposited after Chernobyl accident, Cs-137 poses considerable environmental and radiological problemdue to its relatively long half-life (30.17 gamma), its abundance in the fallout, high mobility and similarity to potassium as the major plant nutrient. In this study the samples of undisturbed surface soil (n = 250) were taken from 70 regions in Belgrade, during 2006-2010. The specific activities of Cs-137 were measured by gamma-ray spectrometry. Based on obtained results, the external effective dose rates were calculated according to the internationally accepted activity to dose rate conversion equations. The specific activities of Cs-137 were geographically mapped. The presence of Cs-137 has been detected in all soil samples, with high variability of its specific activity, ranging from 3 to 87 Bq kg(-1).The mean specific activity of Cs-137 was 23 Bq kg(-1) and the corresponding absorbed dose was 1.5 nSv h(-1). The observed range reflects the inhomogeneity of the deposition process following the Chernobyl accident. It could also be attributed to topographic differences and spatial differences in physicochemical and biological soil properties, soil type and vegetation cover. The results of the present study could be valuable database for future estimations of the impact of radioactive pollution.

In this study the samples of undisturbed surface soil (n = 250) were taken from 70 regions in Belgrade, during 2006-2010. The specific activities of Cs-137 were measured by gamma-ray spectrometry. Based on obtained results, the external effective dose rates were calculated according to the internationally accepted activity to dose rate conversion equations. The specific activities of Cs-137 were geographically mapped. The presence of Cs-137 has been detected in all soil samples, with high variability of its specific activity, ranging from 3 to 87 Bq kg(-1).The mean specific activity of Cs-137 was 23 Bq kg(-1) and the corresponding absorbed dose was 1.5 nSv h(-1). The observed range reflects the inhomogeneity of the deposition process following the Chernobyl accident. It could also be attributed to topographic differences and spatial differences in physicochemical and biological soil properties, soil type and vegetation cover. The results of the present study could be valuable database for future estimations of the impact of radioactive pollution.",

AB  - The concentration of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the steel production facility in Serbia was determined to assess the contribution of emissions to pollution. The mean concentrations of Cd, Co, Cu, Ni, Pb and Zn were found to be higher than values reported for uncultivated soils world-wide and also exceeded mean concentrations of metals in European soil. Analysis of variance revealed the influence of latitude, longitude and distance from the emission source on heavy metal concentrations in soil. Multivariate statistical techniques (cluster analysis and factor analysis) confirmed previous findings and were also used to investigate relationships between heavy metal concentrations and soil particle size fractions. Regression analysis showed that the latitude, longitude and distance from the source are good predictors of heavy metal concentrations in soil. Geostatistical analysis revealed the spatial distribution of heavy metal concentrations in soil and their correlation with prevailing winds in the investigated area. (C) 2014 Elsevier Ltd.

AB  - The specific activities of natural radionuclides (K-40, Ra-226 and Th-232) and Chernobyl-derived Cs-137 were measured in soil profiles representing typical soil types of Belgrade (Serbia): chernozems, fluvisols, humic gleysols, eutric cambisols, vertisols and gleyic fluvisols. The influence of soil properties and content of stable elements on radionuclide distribution down the soil profiles (at 5 cm intervals up to 50 cm depth) was analysed. Correlation analysis identified associations of K-40, Ra-226 and Cs-137 with fine-grained soil fractions. Significant positive correlations were found between Cs-137 specific activity and both organic matter content and cation exchange capacity. Saturated hydraulic conductivity and specific electrical conductivity were also positively correlated with the specific activity of Cs-137. The strong positive correlations between Ra-226 and Th-232 specific activities and Fe and Mn indicate an association with oxides of these elements in soil. The correlations observed between K-40 and Cr, Ni, Pb and Zn and also between Cs-137 and Cd, Cr, Pb and Zn could be attributed to their common affinity for clay minerals. These results provide insight into the main factors that affect radionuclide migration in the soil, which contributes to knowledge about radionuclide behaviour in the environment and factors governing their mobility within terrestrial ecosystems.

AB  - A survey of radium activity concentrations in well and spring waters in Serbia was conducted and their correlations with geological formations were analysed. Water samples were collected from 170 sampling sites and analysed by gamma-ray spectrometry. The mean activity concentrations of Ra-226 were found to be 0.36 Bq L-1 and 0.57 Bq L-1 in well and spring waters, respectively. In more than 90% of the analysed waters the Ra-226 activity concentrations were below 1 Bq L-1. The highest activity concentrations of this radionuclide (up to 17 Bq L-1) were found in crystalline rocks- and carbon dioxide rich-aquifers. The mapping results provide a baseline to identify regions that may require additional assessment of radiation exposure by local communities. (C) 2011 Elsevier By. All rights reserved.

AB  - Terrestrial radiation exposure emitted from naturally occurring radionuclides, such as 40K and radionuclides from the 238U and 232Th series and their decay products represent the main external source of irradation to human body. The purpose of this study was to provide the assessment of the doses from terrestrial exposure of population in Belgrade. The gamma dose rate, annual effective doses and external hazard indexes due to terrestrial natural occurring radionuclides (226Ra, 232Th, 40K) were calculated based on their activities in soil samples in Belgrade determined by gamma-ray spectrometry. The mean value of the total absorbed gamma dose rate outdoors due to terrestrial radionuclides for Belgrade was 59 nGy/h which is close to the worldwide average value (58 nGy/h). The values of the gamma dose rate varied among sampling locations as a consequence of different geological formations in the investigated area. The mean value of annual effective dose of 73 Sv was significantly lower than the maximum allowed dose of 1 mSv for the population and was consistent with the worldwide average value. The mean value of external hazard index was found to be 0.28. The results of this assessment study pointed out that there is no significant radiation risk to the population of Belgrade due to terrestrial exposure to radiation from natural sources outdoors.

AB  - Soil is the main source of continuous radiation exposure to human. It also acts as a medium of migration for transfer of radionuclides to the biological systems and hence, it is the basic indicator of radiological contamination in the environment. Radionuclides in soil take part in several biogeochemical processes that eventually determine their mobilization and availability for ecological processes. Knowledge of their distribution in soil is very important in radiation protection research because it forms a baseline for impact assessments in the environment wherever there is radioactive contamination from practices or releases from accidents. The soil radioactivity is important for the purposes of establishing baseline data for future radiation impact assessment, radiation protection and exploration. Natural environmental radioactivity and the associated external exposure due to gamma radiation depend primarily on the geological and geographical conditions, and appear at different levels in the soils of each region in the world. In addition to natural radionuclides, radiocaesium is a radiologically important contaminant of the soil environment. Radiocaesium was introduced into the atmosphere through nuclear weapons testing and nuclear accident especially that in Chernobyl. Due to its long physical half-life, high fission yield and very low migration velocity in soil environment, this radionuclide is very hazardous in the radioecological context. In many soil conditions it is readily available for uptake to plants resulting in potential contamination of the human food chain. In this chapter the characteristics of radionuclides commonly present in soil and factors influencing their distribution in soil are summarized. The results of extensive studies conducted in Serbia on spatial distribution of radionuclide activity concentrations in soil, their mutual relationships and assessments of radiation exposure of population are presented. © 2012 by Nova Science Publishers, Inc.

AB  - Mosses and lichens have an important role in biomonitoring. The objective of this study is to develop a neural network model to classify these plants according to geographical origin. A three-layer feed-forward neural network was used. The activities of radionuclides (Ra-226, U-238, U-235, K-40, Th-232, Cs-134, Cs-137 and Be-7) detected in plant samples by gamma-ray spectrometry were used as inputs for neural network. Five different training algorithms with different number of samples in training sets were tested and compared, in order to find the one with the minimum root mean square error. The best predictive power for the classification of plants from 12 regions was achieved using a network with 5 hidden layer nodes and 3,000 training epochs, using the online back-propagation randomized training algorithm. Implementation of this model to experimental data resulted in satisfactory classification of moss and lichen samples in terms of their geographical origin. The average classification rate obtained in this study was (90.7 +/- 4.8)%.
