Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure (whether it is acute or chronic), route of exposure, species, age, sex, and environment.
Toxicology in public health is a field that focuses on the study of harmful effects of chemical, biological, and physical agents on human health, as well as the prevention and management of toxic exposures within the context of public health. It involves the assessment of risks associated with exposure to toxic substances and the development of strategies to minimize those risks and protect public health.
Toxicology in public health aims to identify, understand, and mitigate the risks associated with toxic substances to safeguard public health. By conducting research, risk assessments, and communication, toxicologists play a crucial role in preventing toxic exposures, protecting vulnerable populations, and promoting healthier environments for communities.
