Ecotoxicology is crucial for understanding the impacts of pollutants on ecosystems and human health. This field investigates how chemical substances affect living organisms, including their physiological responses, reproductive success, and community structures. By studying these effects, scientists can identify thresholds for harmful exposure and assess the risks posed by environmental contaminants. Understanding these impacts aids in developing regulations and management practices to minimize pollution and support ecosystem recovery. Ultimately, ecotoxicology contributes to conserving biodiversity, promoting healthier ecosystems, and safeguarding public health.
