| Abstract: | In this study,the ecotoxicological effects and the risk of environmental releases of nano-TiO2 and nano-ZnO were evaluated using earthworm(Eisenia foetida)as tested biological subjects.The contact filter paper test(with doses of 0,0.15,0.75,1.5 and 3.0 mg cm-2)and solution test(with doses of 0,10,50 and 100 mg L-1)were used to determine toxicities of the two nanoparticles.After 48-h administration,response of the antioxidant systems and DNA damage of the earthworm were selected as assessment indicators.The ... |
