Ecotoxicity is the study of the harmful effects of pollutants and contaminants on ecosystems, including both aquatic and terrestrial environments. This field of research focuses on understanding the impact of toxic substances on organisms, populations, communities, and ecosystems, as well as the mechanisms by which these substances cause harm. Ecotoxicity research plays a crucial role in assessing and managing environmental risks, informing policies and regulations, and ultimately protecting biodiversity and ecosystem health. This interdisciplinary field combines principles of toxicology, ecology, chemistry, and environmental science to study the interactions between pollutants and living organisms in the environment.
