Speciations of Trace Metals in the Accumulation Bogovina on the Crni Timok River
(Polish Journal of Environmental Studies, 2009)
Samples of various ecochemical types of soil were collected in the region of the future accumulation of Lake Bogovina (Serbia). They were analyzed for ten elements using AAS, GFAAS and ICP. Investigation of the nature of ...
Analysis of the bioavailability of Cr(III) and Cr(VI) based on the determination of chromium in Mentha piperita by graphite furnace atomic absorption spectrometry
(Journal of the Serbian Chemical Society, 2011)
Mentha piperita L. (Lamiaceae) was cultivated under the controlled laboratory conditions in the presence of varying levels of trivalent and hexavalent chromium in order to determine its capacity to control chromium uptake ...
Mass Concentrations and Indoor-Outdoor Relationships of Pm in Selected Educational Buildings in Nis, Serbia
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2015)
Mass concentrations of particulate matter (PM) fractions were measured in educational buildings in the city of Nis, Serbia. Two sampling campaigns were conducted in winter periods. The first campaign was in the period from ...
A simulation experiment as a method for the investigation of the mobility of heavy metals from inundated land
(Journal of the Serbian Chemical Society, 2010)
A simulation experiment was used to study the interaction of river water with different soils (amble land, orchards, meadows, pastures and forestland). The results obtained by sequential extraction before and after the ...
