New dimensions in our understanding of the human health effects of environmental pollutants
- Univ. of Albany, Rensselaer, NY (United States)
The term {open_quotes}hazardous{close_quotes} waste is used primarily in reference to potential hazards to human health and, to a lesser decree, hazards to wildlife and the ecosystem. Many of the chemicals associated with hazardous waste sites are also widely distributed throughout the environment; therefore, the health hazards associated with hazardous waste sites are not different from those associated with general environmental contamination. Until recently, it was generally assumed that cancer was the human disease of greatest concern associated with toxic chemicals. In fact, most governmental regulations related to exposure are designed on the basis of presumed cancer risks. Since the evidence that hazardous chemicals can cause cancer is strong, it is appropriate to be concerned about cancer risk. Recent evidence, however, has triggered a reevaluation of the assumption that only cancer is of concern. New evidence suggests that noncancer endpoints may occur more frequently than cancer, may affect a greater number of individuals, and may occur at lower concentrations. Of particular concern is evidence of irreversible effects on the embryo and very young children, which influence intelligence, attention span, sexual development, and immune function. Although these effects are often subtle and difficult to quantify, the combined evidence is sufficiently compelling to necessitate a reevaluation of those outcomes of primary concern to human health. 57 refs., 2 figs., 3 tabs.
