Toxicology of nanomaterials and environment

Abstract

Manufactured nanoparticles demonstrated a variety of biological activities, including toxicity. The goal of this review articles is to summarize some evidence of a variety of toxic effects produced by manufactured nanoparticles, including both the data from literature and the new data of the authors (e.g., 42). The toxicity of nanomaterials was shown both to prokaryotic and eukaryotic organisms. As for eukaryotic organisms, toxicity was found in bioassays with both animal and plant test systems. In further studies, it is necessary to continue the studies of various aspects of toxicity of nanoparticles, and to extend the range of organisms and test systems that are being used for assessing the biological effects of nanomaterials. The methods that were previously developed to study phytotoxicity of chemicals 15-28, 48 will be useful to generate new data on toxicology of nanomaterials.
