Document Summary
Environment: a complex system of living things and natural processes, the human species is one player in this web. Chemical - industrial, pollutants, pesticides, lead in paint, cigarette smoke. Biological - biohazards agents of infectious disease (mold, gmos) Physical - contact with energy (radiation, noise, airborne dust particles, mechanical objects, extremes of heat and cold) Environmental health: more than industrial pollution, not based on genetic traits. Does not include an analysis of the effect of genetics on the likelihood of illness / injury from exposure to chemicals and hazards as a cause of disease. Social / behavioural hazards: (drug use) not a part of environmental health. Environmental health does not consider the link between hazards and social behavioural elements. Greater focus on anthropogenic hazards than naturally occurring hazards (floods, tsunamis, windstorms). Natural disasters can however create environmental health hazards - an example would be the soup" of industrial sewage wastes from hurricane katrina affecting health.
