Toxicologists study the effects of chemicals, substances, and environmental factors on living organisms, particularly humans. They assess risks, ensure safety, and contribute to regulatory compliance in industries such as pharmaceuticals, environmental science, and consumer products. Junior toxicologists typically assist in laboratory work and data analysis, while senior toxicologists lead research projects, develop safety protocols, and provide expert guidance on toxicological risks.
