Global Toxicology and Risk Assessment

Toxicology

Toxicology is a division of biology, chemistry, and medicine concerned with the study of the adverse reactions of chemicals on living organisms. It also studies the harmful effects of chemical, biological and physical agents in biological systems that establish the extent of damage in living organisms. The relationship among dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity includes the dosage (and whether it is acute or chronic); the route of exposure, the species, age, sex and environment. Toxicologic analysis plays a very crucial role in the modern-day investigations. Basic principles of several disciplines like analytical chemistry, biochemistry, epidemiology, pharmacodynamics, pathology, and physiology are applied in such kind of analysis.
