Ecotoxicologists employ a variety of methods to assess the impact of contaminants, including: - Field studies to observe the effects of pollutants in natural settings. - Laboratory experiments using model organisms to determine toxicity levels. - Mesocosm studies which simulate natural environments under controlled conditions. - Biomarkers to detect exposure and effects at the molecular or cellular level. - Ecological risk assessment to predict the potential adverse effects of contaminants on the environment.
