What does ecotoxicology study?

• A. The economic impact of pollution
• B. The effects of toxic substances on organisms
• C. The restoration of damaged ecosystems
• D. The prevention of environmental degradation

Answer: (B)

Ecotoxicology is a branch of science that focuses on the study of the effects of toxic substances on living organisms and the environment. It examines how these substances can impact individual organisms, populations, communities, and ecosystems as a whole. The discipline integrates principles from toxicology, ecology, and environmental science to assess the risks that pollutants pose to wildlife and humans.

By investigating the biological and ecological consequences of exposure to toxic chemicals, ecotoxicology plays a key role in understanding the mechanisms of toxicity, the pathways of chemical exposure, and the potential for bioaccumulation and biomagnification. This knowledge is crucial for evaluating the health of ecosystems and developing appropriate strategies for managing and mitigating the effects of pollution.

While assessing the economic impact of pollution, restoring damaged ecosystems, and preventing environmental degradation are important fields of study, they do not encompass the specific focus that ecotoxicology has on the interactions between toxic substances and biological systems.
