The scope of toxicology is vast, encompassing various areas such as environmental toxicology, pharmaceutical toxicology, forensic toxicology, and clinical toxicology. Each sub-discipline focuses on different aspects, such as the impact of chemicals on the environment, drug safety, the role of toxins in criminal investigations, and the treatment of poisoning cases. Toxicologists work in diverse settings, including research institutions, regulatory agencies, and industry, to evaluate the safety and risk of chemicals.
