Phytotoxicity of nanoparticles--problems with bioassay choosing and sample preparation.

ABSTRACT: For a full estimation of the risk related with the presence of engineered nanoparticles (ENPs) in the environment, the use of the current ecotoxicological methods may prove insufficient. In the study presented herein, various methods of assessment of ecotoxicity were applied to compare the phytotoxicity of three ENPs: nano-ZnO, nano-TiO2 and nano-Ni. The toxicity was assayed both for aqueous solutions of the ENPs (the germination/elongation test and Phytotestkit F(TM)) and for ENPs added to soil (Phytotoxkit F(TM) and modified Phytotoxkit F(TM)). Lepidium sativum was used as a test plant. The scope of the study also included the assessment of the effect of the method of ENP application to the soil (as powder and aqueous suspension) on their phytotoxicity. In the course of the study, no eff
