Emerging contaminants – general aspects: sources, substances involved, and quantification
Summary
This review covers a range of emerging environmental contaminants — including microplastics in water bodies, pharmaceuticals, illicit drugs, and medical-use metals — discussing their sources, harmful effects, and detection methods. It provides useful context for understanding how microplastics fit into the broader landscape of modern chemical pollution threatening human and ecosystem health.
This review reports a discussion involving sources, adverse effects, and quantification of emerging contaminants that have polluted the environment, such as chemical elements employed in medicine (antimony, barium, and gadolinium), microplastics in water bodies, in addition to pharmaceutical, illicit drugs, and their metabolites in wastewater and sewage sludge. It also addresses the pollution caused by emerging contaminants in urban areas, such as gas stations and hairdressing salons. The main analytical methods recommended for determining all these contaminants are briefly reported.
