What is Toxicology? Career Opportunities in Toxicology

Toxicology is the scientific study of the adverse effects of chemical substances on living organisms and the environment. It involves understanding the nature, mechanisms, and effects of harmful substances, including chemicals, biological agents, and physical agents, on biological systems. Toxicology aims to identify, quantify, and manage the risks associated with exposure to toxic substances.

Key Areas of Toxicology

1. Descriptive Toxicology: Involves the testing and description of toxic effects of substances on organisms, often through laboratory experiments.
2. Mechanistic Toxicology: Explores the biochemical, cellular, and molecular mechanisms by which toxic substances exert their effects.
3. Regulatory Toxicology: Focuses on setting safety standards and regulations to protect public health and the environment.
4. Environmental Toxicology: Studies the impact of toxic substances on ecosystems and wildlife.
5. Forensic Toxicology: Involves the detection and analysis of toxic substances in legal contexts, such as criminal investigations.
6. Clinical Toxicology: Deals with the diagnosis and treatment of poisoning and adverse drug reactions in humans.
7. Occupational Toxicology: Examines the effects of workplace exposures to chemicals and other hazardous substances on workers' health.
