Identify and describe 3 environmental health hazards that cause ill health,accidents,crises and disasters within the south african and global community
Weegy: 1. Air Pollution - can affect our health in many ways with both short-term and long-term effects. Different groups of individuals are affected by air pollution in different ways. Some individuals are much more sensitive to pollutants than are others. [ Young children and elderly people often suffer more from the effects of air pollution. People with health problems such as asthma, heart and lung disease may also suffer more when the air is polluted. 2. Drought - is an extended period of months or years when a region notes a deficiency in its water supply whether surface or underground water. Generally, this occurs when a region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years, even a short, intense drought can cause significant damage and harm the local economy. 3. Flood - is an overflow of water that submerges or "drowns" land.[1] The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water.[2] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Flooding may result from the volume of water within a body of water, such as a river or lake, which overflows or breaks levees, with the result that some of the water escapes its usual boundaries,[3] or may be due to accumulation of rainwater on saturated ground in an areal flood. ] (More)

The community can also prepare by establishing Community Emergency Response Teams to respond in the period immediately after a disaster. CERTs assist existing response teams and assume the same functions as response personnel.
CERTs are among a variety of agencies and personnel that cooperate to provide assistance in the aftermath of an emergency or disaster. The keys to a CERT’s effectiveness are in:

Familiarity with the type of event and the types of damage that are most likely to result.

Adequate preparation for the event and its aftermath.

Proper training in the functional areas to which CERTs are assigned, including:

¦ Fire suppression.
¦ Light search and rescue.
¦ Disaster medical operations.
¦ Logistics.

Name 5 sources of the environmental health hazard that can contribute to one's ill health inside home
Weegy: People come into contact with toxic substances in many ways. Exposure to a toxic substance may occur at several points in the use cycle of the substance. [ People work in a plant where the substances arise as waste from an industrial process and do not change clothes or wash before coming home. They may reside near hazardous waste disposal sites which are illegal or poorly designed or managed, with opportunities for exposure as a result of accidents or careless handling or lack of containment of the substance, or lack of fencing to keep children off the site. Exposure may occur in the home as the result of consumer products that are mislabelled, poorly stored and not child-proof. Three routes of exposure are by far the most important in considering the implications for toxicity of hazardous waste: inhalation, ingestion and absorption through the skin. Once absorbed, and depending on the route of exposure, there are many ways in which people can be affected by toxic chemicals. Obviously, the list of possible toxic effects associated with hazardous waste is very long. However, public concern and scientific studies have tended to concentrate on the risk of cancer and reproductive effects. In general, this has reflected the profile of chemical hazards at these sites. One is that unlike air pollution and surface water pollution, the chemicals in land pollution are not easily available to people. People may live in areas highly contaminated by chemicals, but unless they actually come in contact with the chemicals by one of the routes of exposure mentioned above, no toxicity will result. Another reason may be that the chronic effects of exposure to these toxic chemicals take a long time to develop and are very difficult to study. Yet another reason may be that these chemicals are less potent in causing chronic health effects in humans than is usually supposed. Notwithstanding the human health effects, the damage of land pollution to ecosystems may be very great. ... (More)
