CONTAMINANTS OF EMERGING CONCERN CHALLENGE ECOTOXICOLOGY

摘要

Accurate hazard and risk assessment of contaminants of emerging concern challenges fundamental concepts and methods within environmental toxicology. Prominent among the contaminants of emerging concern today are active pharmaceutical ingredients (APIs) and, increasingly, nanoparticles (NPs). However, many, if not all, other categories of new and existing substances could, in theory, also become contaminants of emerging concern. The term does not necessarily imply that all contaminants of emerging concern are new, merely that improved analytical chemistry has allowed us to discover existing contaminants in the environment or that new properties associated with existing compounds are revealed and cause concern.
