On the one hand, it seems the large environmental share of health problems is primarily, due to factors related to poverty, such as limited to access to proper food, housing, health care and drinking water. Environmental determinants of human health in developing or developed countries are related. On the other hand, those to the exposure to air pollutants ( particularly in urban areas and chemicals in the environment than to poor living conditions. Also sources of human exposure to chemicals are many and varied. Chemicals can reach the environments, for example, through emissions from industries, anti-fouling paints on marine vessels, pesticides in agriculture, waste incineration and leakage from waste disposal sites. When emissions of chemicals from industries and other point sources of pollution have lead to poor quality of life, source of chemical exposure. Intensive agricultural production uses chemicals in pesticides and fertilizer and in feed additives and medication for livestock. Residues remain in fruit, grains, vegetables, meats and daily products, all of which can reach the consumer. Other sources of chemicals in food include bio-accumulative chemicals in the environment, such as heavy metals and persistent organic pollutants, which can be found in fish, meat and dairy products. So, environment pollution can influence human need to eat bad or unhealthy food to cause we have poor quality of life to live, such as the high income group or middle income group or low income group of families in our societies fairly. Other human health risks that have recently received considerable attention include unsafe livestock feeding practices through which toxins reach the food chain unintentionally. Dioxins that have accidentally contaminated poultry feeds that contain diseased animal remains can cause the so-called " mad cow disease" in livestock which has been linked to a new form of disease. The effects on health from exposure to chemicals and air pollutants vary from allergies to cancer. Although, the link between exposure and disease is often not clear, Even at low exposure levels, urban are pollutants can cause, asthma, allergies, respiratory diseases and cardiovascular disease if the exposure is continuous or long term. Heavy metals have been shown to cause neurological disorders and various cancers. In addition to, physical diseases, environmental contamination can also cause psychological problems. Noise, one of the determinants of the quality of urban life can have an impact on human health, decreasing the quality of life and potentially contributing to depression.For Ireland, UK country example, this country politicians and policy makers believe the role of environment can be used to measure quality of life, concerning on either in its own right or relative to economic and social aspects of quality of life. Agreement on what measures quality of life and how it can be measured by the role of environment, not just in Ireland, but everywhere. The conventional approach is used for policy has been to use measure of gross domestic product( GDP) or regional valued added. However, it is acknowledged that such conventional economic measures have only a partial relationship with societal wellbeing. To the extent that economic measures are related to public products and consumption, there are also pressing issues in relation to public products and the sustainability of economic growth. However, the role of environmental factor can influence resource use and human's behavioral consumption.
