Toxicology is the scientific study of the harmful effects of substances on living organisms, exploring how chemicals, drugs, and environmental agents interact with biological systems. It investigates exposure levels, mechanisms of toxicity, and the short- and long-term health impacts of various compounds. Rooted in biology, chemistry, and medicine, toxicology plays a vital role in public health, pharmaceutical development, environmental safety, and regulatory policy. Researchers in this field assess risks, identify potential hazards, and contribute to the safe design and use of chemicals in everything from consumer products to industrial processes.
