Biomonitoring is a scientific method that involves measuring and analyzing biological markers in organisms to assess exposure to environmental contaminants and potential health impacts. This research area involves studying how contaminants are absorbed, metabolized, and excreted by living organisms, as well as identifying the potential effects of these contaminants on individual health and ecosystem health. Biomonitoring is used in various fields such as environmental science, toxicology, and public health to track and monitor exposure to pollutants, identify sources of contamination, and inform environmental and public health policies and practices.
