How do environmental factors influence the safety of nanomaterials?
Environmental factors such as temperature, pH, and the presence of other chemicals can significantly alter the behavior and toxicity of nanomaterials. For example, nanoparticles might aggregate or dissolve, changing their reactivity and potential for harm. Additionally, the interaction of nanomaterials with biological systems and ecosystems is complex and not fully understood, posing risks of bioaccumulation and unforeseen ecological impacts. Therefore, comprehensive environmental assessments are crucial to evaluate the safety of nanomaterials in various contexts.
