Environmental toxicology is the study of how pollutants and toxic substances impact the environment and living organisms. This field examines the effects of chemicals, heavy metals, pesticides, and other contaminants on ecosystems, wildlife, and human health. By understanding these impacts, environmental toxicologists aim to mitigate and manage risks associated with exposure to harmful substances.

Key areas of focus in environmental toxicology include the assessment of chemical toxicity, the movement and fate of pollutants in the environment, and the effects on biological systems. Toxicologists evaluate how pollutants like mercury, lead, and persistent organic pollutants (POPs) accumulate in the food chain, potentially leading to adverse health effects in both wildlife and humans. For instance, mercury contamination can cause neurological damage in fish and, subsequently, in humans who consume these fish.

Environmental toxicologists also study the impact of pesticides on non-target species and ecosystems. Pesticides can disrupt ecological balance, harming beneficial insects and aquatic organisms. Understanding these effects is crucial for developing safer and more sustainable pest management practices.

Moreover, environmental toxicology involves assessing the long-term effects of environmental pollution, including chronic exposure to low levels of contaminants. This research is essential for formulating regulations, setting safety standards, and designing remediation strategies to protect environmental and public health.
