Environmental pathology, the field that deals with the disease caused by exposure to harmful external agents and deficiencies of vital substances, includes all nutritional, infectious, chemical, and physical causes of illness. Nearly a century ago a few physicians cultivated an interest in diseases that seemed to have strict geographical boundaries ; as a result, a discipline called “geographic pathology” was created. Geographic pathology was concerned with diseases endemic to certain areas of the world, notably parasitic and infectious diseases that seemed unique to those locales. A minor component dealt with nutritional disease and a separate discipline covered forensic medicine. With the discovery that chemical agents are mediators of a variety of tissue changes, and with the recognition that many of these causative agents are environmental contaminants, a component called “occupational disease” was added to the roster. Finally, disease due to contaminants in the broadest sense was included to constitute the field of “environmental pathology”. In comparison to all other environmental hazards, the mortality and morbidity rate is extremely high in cases of voluntary intake of tobacco smoke, alcohol (ethanol , ethyl alcohol), and illicit psychoactive drugs. Almost every type of physician is likely to have extensive experience with diseases related to the intake of these substances. Radiation, air pollution, and industrial exposures are relatively minor dangers compared to the problems that people willingly bring upon themselves.
