What is environmental toxicology and why is it important for public health?

Environmental toxicology is the scientific study of the harmful effects of chemical, physical, and biological agents on living organisms within ecosystems. It investigates how these agents are transported and transformed in the environment, their interactions with biological systems, and their ultimate impact on ecological health and human well-being.

Its importance in public health includes:

• Risk Assessment: It helps identify and evaluate the potential health risks posed by environmental contaminants, such as pollutants in air, water, and soil, to human populations.
• Policy and Regulation: It provides the scientific basis for developing public health policies and regulations to control pollution, set exposure limits, and protect communities from toxic substances.
• Disease Prevention: By understanding the sources, pathways, and effects of environmental toxins, it contributes to preventing environmentally-induced diseases and health conditions in humans.
