Question and answer
Identify and describe 3 environmental health hazards that causes illness,crises and or disaster.
1. Physical hazard[energy of one form or another] 2. Chemical hazard [matter i.e. substances whether natural or man-made] 3. Biological hazard [living things]. Hazards can present themselves to us in various media e.g. air, water. [ The influence they can exert on our health is very complex and may be modulated by our genetic make up, psychological factors and by our perceptions of the risks
that they present. The following deals with general environmental health hazards, and not extremes of climate, occupational hazards, hazards associated with food, most "accidents" or sexually transmitted disease. Health effects from economic and social consequences of environmental change are also not considered here. Associations between an exposure and an adverse health effect do not, on their own, prove that the former is the cause of the latter. Many other non-causal associations could explain the findings. These concerns explain why the language in this context may well be "hedged" even though you might have formed impressions from other sources that some postulated causal associations had been proven.
