ABSTRACT
This chapter focuses on the environmental health encompasses the discipline which centers around disease-causing chemicals or pathogens that occur naturally in our environment and those introduced by man. Frequent exposure to relatively large amounts of a chemical, subacute toxicity, can produce both chronic and acute symptoms. Some chemicals to which workers are exposed occupationally are carbon tetrachloride, chlorobenzene, cresols, cyanide, lead, polychlorinated biphenyls, dioxins, and carbon monoxide. Lead sulfide, a naturally occurring form of lead, has been mined, and its production, which has increased dramatically since the industrial revolution, has resulted in increased environmental pollution. Such limitations on population growth is referred to as environm ental resistance When considering noise pollution, busy airports, and neighbors playing annoyingly loud music initially come to mind. Exposure of the general population to lead and its compounds results from breathing air, drinking water, and eating many foods that contain lead.
