Abstract

Epidemiology is the study of events that occur upon or on populations or groups, described by the number of cases in a given population. This entry focuses on the traditional subject areas of environmental and occupational epidemiology. One of the biggest problems with environmental epidemiology is that studies rarely find a strong association for cause and effect. This is due to the lack of a clear study population, low-level exposures, inaccurate exposure dose, random events and related confounding factors.
