Anionic pollutants

Anionic pollutants represent a broad category of negatively charged chemical species that contaminate environmental resources such as water and soil, posing significant risks to human health (EPA, 2023). This group includes inorganic ions like nitrates and perchlorates, as well as complex organic molecules such as per- and polyfluoroalkyl substances (PFAS) (CDC, 2022). These substances are not therapeutic targets; rather, they are exogenous toxins that interfere with normal physiological functions. For example, perchlorate is a known endocrine disruptor that competitively inhibits the sodium-iodide symporter in the thyroid, potentially leading to decreased thyroid hormone production (National Research Council, 2005). Chronic exposure to various anionic pollutants has been linked to adverse outcomes including methemoglobinemia, developmental toxicity, and an increased risk of certain cancers (StatPearls, 2023). Because they are not biological receptors or enzymes, they are not targeted by traditional drugs for therapeutic benefit. Instead, medical management focuses on mitigating toxic effects or using sequestrants to facilitate their removal from the body in cases of acute exposure.
