Environmental Chemistry and Toxicology

Environmental Chemistry and Toxicology is an interdisciplinary field that investigates the sources, reactions, transport, and fate of chemical substances in the natural environment, as well as their adverse effects on living organisms. It combines the principles of chemistry to understand how pollutants like pesticides, heavy metals, and industrial byproducts behave in air, water, and soil, with the principles of toxicology to determine the mechanisms and extent of the harm they cause to biological systems, from the cellular level to entire ecosystems. This knowledge is critical for assessing environmental risks, establishing safety regulations, and developing strategies for pollution prevention and remediation.
