Environmental Toxicology and Ecotoxicology

Environmental toxicology and ecotoxicology examine how chemical pollutants—particularly heavy metals and pesticides—enter aquatic ecosystems, accumulate in organisms over time, and disrupt biological processes at the cellular and population level. When fish, invertebrates, or other aquatic species absorb contaminants faster than they can eliminate them, the resulting buildup, known as bioaccumulation, can trigger oxidative stress and tissue damage, making these organisms useful sentinels for monitoring water quality through measurable biomarkers. Understanding these effects matters because contaminated waterways don't stay isolated—pollutants move through food webs, eventually reaching wildlife and human populations that depend on aquatic resources. Active research is working to refine environmental risk assessment frameworks that can account for the combined, often synergistic effects of multiple contaminants present simultaneously, and to identify which biomarkers most reliably signal ecological harm before populations collapse.
