Health concerns [1] underpin many of the current debate about the environmental consequences sniw of erosion. Environmental health threats can be grouped into two categories; modern threats [2], which is associated with the development without health and environmental protections. [3] has been effective enough, and traditional risk [4] generally associated with underdevelopment [5] is (World Health Organization [6], 1997). Modern environmental risks including pollution residential areas [7], Lvdgby urban air [8], and poor control of solids and hazardous wastes, chemical and radioactive hazards, deforestation and other issues related to ecological and climate change and ozone loss Ramsphr] 9 is. The emergence and re-emergence of infectious diseases [10] and it is classified as a modern environmental hazards due to its close association with the consequences of economic development. Traditional environmental health risks include poor control of vectors of disease, poor health [11], contamination of food and drinking water, air pollution and particulate fire due to internal and external events, and natural disasters and Azbynbrdn flawed pathology.
The evidence on the health effects of certain environmental risks of modern health care is often fragmented and supported by experimental conditions that were not enough data Drmrzgzary levels does not show the actual populations. However, there is evidence suggesting that the chemicals and gases, in air, water and food are the result sniw of industrial or agricultural processes are distributed in the environment and can have negative effects on their health. In addition, sniw exposure to ionizing radiation [12] of nuclear power stations or from natural sources has been associated with negative health outcomes (Kvrvln and Jlstrvm [13], 1995). sniw
A major health threat in developed countries and in developing air pollution, especially sniw particulate matter suspended in [14], which was estimated at about three million sniw people per year worldwide swallow death (WHO 1997). Spam [15] involving the small and large particles of combustion are caused by mechanical processes. sniw Spam smallest molecules, typically diesel smoke, fire, smoke, and there are some types of nuclear activities, are dangerous to human health because they can deep into the respiratory tract [16] may influence (De Souza [17] 1999 ). It should be noted that although the particles of pollution in developed countries, mainly due to environmental pollutants is modern, traditional sources such as smoke from burning home in developing countries [18] have contributed in the creation of a large part of spam. Lead [19] One of the common blocks spam. There is evidence sniw regarding the effects of lead exposure, reduced IQ, expanding mental injuries [20], low birth weight, and disorders of the nervous system [21] is sought (Pvkvk [22] et al (1994), World Health sniw Organization 1997). Inhaling smoke from burning gasoline and diesel with a significant source of lead in mild persistent sniw Mrzbvdn Drhaltvshay countries that still have lead in gasoline and diesel consumption, they are.
It occurs in many contaminates the air, food and water resources there. Use of fertilizers and pesticides in agriculture and food is one of the main sources of groundwater pollution. In some developed countries it has been found that the daily intake of cadmium sniw [23], lead [24], mercury [25], PCB and [26] and pesticides over the Hungarians and especially of children and children over Hungarian sniw areas designated is (Bhatt and hair [27], 1997). sniw In drinking water, arsenic [28] as a continuing threat to global health because it can cause cardiovascular, neurological, and skin and internal cancers including liver cancer sniw [29], lung [30], kidney [31], and bladder [32] is. A strong correlation between ingestion of nitrates and recurrent respiratory tract infections have been reported (Gupta [33] et al, 2000). Since many chemicals are passed through the wall of the fetus when pregnant women consuming contaminated food or water that are health risks for the unborn baby.
It is believed that the modern environmental pollutants negative effects on human fertility and reproductive health, although the evidence on this issue is still controversial. In this regard, organic and inorganic chemicals, such as pesticides and hormones sniw all play a role (Swan [34] et al, 1997). For example, exposure to PCB makes health worse early birth and early childhood (Svyn [35] 1991) and impaired fertility, growth, irreversible disabilities and behavioral sniw changes fine new born is (Gylbrsvn [36] et al, 2000). Shymyayay factors that are used to enhance ovulation and reproduction associated with negative health outcomes, such as pregnancy sniw feasibility Tqlylyafth [37], the incidence of unintentional Sqtjnyn wider, and increased risk of breast, ovary, and uterus were (Tvkr [38] In 1996, Van] 39] et al, 1999). It should be noted that even though environmental factors can have a negative effect on fertility, but there is little evidence that the overall level of fertility has been affected. In Belarus and Ukraine, [40], where studies have shown that the period immediately following the nuclear accident [41] has been a substantial reduction in fertility, it seems that other factors have played an important role in impaired fertility.
