Abstract

Pollutants, ranging from heavy metals to organic compounds and emerging contaminants, pose significant risks to ecosystems and human health. This study evaluates the environmental and toxicological risks associated with pollutants by integrating field data, laboratory analyses, and risk assessment models. We examine the sources, fate, and transport of key pollutants, including their bioaccumulation in organisms and potential toxicity across trophic levels. Our findings reveal that industrial discharges, agricultural runoff, and urban waste streams are primary contributors to pollutant loads, with synergistic effects amplifying their ecological impact. Toxicological assessments indicate that chronic exposure to pollutants such as lead, polycyclic aromatic hydrocarbons (PAHs), and microplastics disrupts physiological processes in both aquatic and terrestrial species. Risk characterization highlights vulnerable ecosystems and populations, emphasizing the need for targeted mitigation strategies. This research underscores the urgency of interdisciplinary approaches to monitor, regulate, and remediate pollutant impacts, offering a framework for sustainable environmental management.
