Welcome to the Environmental Toxicology MCQs with Answers, it helps learners quickly identify areas for improvement in Environmental Toxicology Online Test.
| Environmental toxicology is a multidisciplinary field that examines the adverse effects of chemicals and pollutants on living organisms and ecosystems. It focuses on understanding how pollutants enter the environment, their distribution and persistence, and their impacts on biological systems. Key areas of study in environmental toxicology include the mechanisms of toxicity, ecological risk assessment, and the development of strategies to mitigate and manage environmental contaminants.
In environmental toxicology, researchers investigate the interactions between pollutants and organisms at various levels of biological organization, from molecular and cellular effects to population and community dynamics. This field plays a crucial role in identifying environmental hazards, assessing the risks associated with chemical exposure, and informing regulatory decisions to protect both human health and ecological integrity. |
