Nanomaterials as possible contaminants: the fullerene example.
An assessment of the potential risks posed by nanomaterials will require case-by-case evaluations of the processes controlling exposure and hazards such as toxicity. Factors that control fullerene transport and transformation in aqueous environments and their relationship to toxicity are discussed. Natural organic matter is observed to either increase or decrease nanoparticle stability while trends in reactive oxygen generation run counter to proposed mechanisms of possible fullerene toxicity.
