Health Problem Identification
In the process of identifying chemical health problems, the near-term and long-term fate of the chemical should be incorporated into the analysis. Chemical health problems yield toxic effects when hazardous chemicals enter the human body and other organisms at concentrations above the “no effects level.” The potential effect of toxicity on living things, especially humans, has driven regulatory initiatives in hazardous waste management. A primary objective of hazardous waste management is to protect human health by reducing the risk associated with hazardous chemicals. Thus, an understanding of toxicology is needed in order to determine if a chemical substance is a health problem. Epidemiology is an important method employed in the identification of human toxicity and health problems resulting from exposure to chemicals. It is the only method that provides direct human evidence to identify toxicity and health problem in humans. Epidemiology analyzes statistical data to determine the relationship between a chemical exposure and the exposed population.
