Comparative phytotoxicity of ZnO nanoparticles, ZnO microparticles, and Zn~(2+) on rapeseed (Brassica napus L.): investigating a wide range of concentrations

摘要

The effects of ZnO nanoparticles (NPs), ZnO microparticles (MPs), and zinc ions (Zn~(2+)) on some growth parameters of rapeseed (Brassica napus) seedlings have been studied. The growth inhibition by ZnO NPs was not stronger than that by ZnO MPs while treatment with Zn~(2+) inhibition was clearly stronger.
