AB  - UV-C irradiation is widely used in the food industry. However, the health effects from dietary exposure to the irradiated pesticide residues retained in foodstuffs are underestimated. In this study, technical chlorpyrifos (TCPF) and its oil in water (EW) and emulsifiable concentrate (EC) formulations were irradiated by UV-C, and their photodegradation products were subjected to toxicity assessment, including determination of acetylcholinesterase (AChE) activity, genotoxicity and oxidative stress using human blood cells as a model system. Toxicity studies were performed using the chlorpyrifos concentrations in the range of those proposed as the maximum residue levels in plant commodities. TCPF, EW and EC photodegradation products induced DNA damage and oxidative stress, and their genotoxicity did not decrease as a function of irradiation time. Irradiated TCPF and EC are more potent AChE inhibitors than irradiated EW. Accordingly, the application of UV-C irradiation must be considered when processing the plants previously treated with chlorpyrifos formulations. © 2018 Elsevier Ltd

AB  - TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M (NH4)(2)SO4 solution in a temperature-controlled bath. The pH values of the suspension were 7, 8 or 9. According to the x-ray diffraction (XRD) analysis the anatase crystallite sizes were about 12 nm, which coincided with the average particle size revealed by scanning electron microscopy (SEM). The Raman scattering measurements have shown the presence of a small amount of highly disordered brookite phase in addition to dominant anatase phase with similar nanostructure in all synthesized powders. BET measurements revealed that all synthesized catalysts were fully mesoporous, except the sample synthesized with 0.07 M (NH4)(2)SO4 at pH=9, which had small amount of micropores. The photocatalytic degradation of herbicide Clomazone was carried out for both the pure active substance and as the commercial product (GAMIT 4-EC) under UV irradiation. The best photocatalytic efficiency was obtained for the catalyst with the largest specific surface area, confirming this parameter as crucial for enhanced photocatalytic degradation of the pure active substance and commercial product of herbicide Clomazone.

AB  - The subject of this research was utilization of concentrated solar radiation simulated with a sodium lamp SONT UV100, in lab condition, on removal of wastewater polluted by methyl-tertiary-butyl-ether (MTBE). The effects of titanium dioxide catalyst (commercial: Degussa P-25 (R) and 100% anatase, as well as sol-gel obtained titanium) on degradation of MTBE have been investigated. The processes were performed in slurry-catalyst batch circulating reactor. The photocatalytic degradation with different concentrations of TiO2 Degussa P-250 (R) catalyst: 2.5 g/L, 1 g/L and 0.50 g/L was studied. Our results showed that the MTBE degradation reached 50.80% in only 60 minutes, when 2.5 g/L of that catalyst was used. Also, the concentrated irradiation in combination with TiO2 (100% anatase) and FeCl3 caused high total degradation degree of 58.22%, for only 30 minutes. We synthesized titanium-dioxide, nanopowders doped with LaCl3 center dot 7H(2)O and FeCl3 center dot 6H(2)O, by sol-gel procedure. The highest degradation rate showed La-TiO2, for only 30 minutes and 48.60% of total degradation.
