Chemical exposure is the study of the potential harmful effects of exposure to various chemicals on living organisms, including humans. This research area aims to identify the sources, pathways, and levels of exposure to chemicals in the environment, as well as to understand the mechanisms by which these chemicals may cause adverse health effects. Researchers in this field investigate a wide range of chemicals, including industrial pollutants, pesticides, pharmaceuticals, and household chemicals, and study their potential impacts on human health, wildlife, and ecosystems. The ultimate goal of chemical exposure research is to identify and mitigate risks associated with chemical exposure to protect public health and the environment.
