What is the Role of Epidemiology in Environmental Health?
Epidemiology plays a critical role in environmental health by studying how environmental exposures affect human health. This includes investigating the health effects of air and water pollution, chemical exposures, and occupational hazards. Through these studies, epidemiologists help develop regulations and guidelines to protect public health. An example is the research on the health effects of lead exposure, which has led to policies reducing lead in gasoline, paint, and water supplies.
