SUMMARY. Phytotoxicity of colloidal solutions of metal-containing nanoparticles (Ag, Cu, Fe, Zn, Mn) has been investigated using a standard Allium cepa (L.) test system. Toxicity of experimental solutions at the organism level was evaluated in terms of biomass growth of onion roots, and cytotoxicity was estimated by the mitotic index of root meristem cells. The colloidal solutions of metal nanoparticles inhibited the growth of Allium cepa (L.) roots due to their ability to penetrate into cells and interact with their components, and thus to inhibit mitosis. According to our results cytotoxicity of test solutions decreases in the following order: Cu ≥ Zn > Ag ≥ Fe. Solution of Mn-containing nanoparticles revealed physiological activity according to root growth reaction.

Key words: Allium-test, colloidal solution of metal containing nanoparticles, cytotoxicity
