Abstract
Currently, large quantities of engineered nanomaterials are being produced for diverse applications, and the trend is expected to increase in the future. This increases the probability that nanoparticles will enter the environment during their production, manufacture, use, or disposal. Despite excessive use, data are lacking on the bioaccumulation, toxicity, and biodegradation of nanoparticles in humans and environmentally relevant species. In addition, limited information is available regarding the weathering potential of both coatings and covalent surface modifications. Therefore, no blanket statements about the toxicity of nanoparticles can be made at this time. Limited ecotoxicological data for nanomaterials preclude a systematic assessment of the impact of nanoparticles on ecosystems. The aim of this chapter is to discuss the status of public and environmental health strategies currently in use to control the possible adverse effects of nanoparticles in the absence of sufficient toxicity data.
