Pollution cancer risk factor

It has become customary among cancer epidemiologists to talk about certain lifestyle factors as important contributors to cancer risk. Lifestyle factors (smoking, dietary patterns, alcohol consumption) are assumed to be largely under the control of individuals. These are distinguishable from factors that are less directly in the control of individuals (occupation, medicines, consumer products), and those over which individuals have little or no control (food additives, pesticides, environmental pollutants). Just how much control individuals have over the various lifestyle factors is of course much debated. 

The Royal Commission on Environmental Pollution reported in 1996 that it was not aware of any study that provided firm evidence of adverse effects of contaminated land on health.10 However, the potential for health effects is real. Exposure to chemicals is a risk factor for several diseases and the International Agency for Research on Cancer has classified over 70 chemicals as human carcinogens, 60 as probable and more than 200 as possible carcinogens.11 There is evidence of an environmental influence in human diseases such as cancer,12 including geographic variation in cancer incidence in migrant populations, occupational studies and animal experiments. A number of studies also appear to suggest an association between other health effects and exposure to environmental chemicals. There are thousands of sites contaminated with hazardous chemicals with the potential to expose human populations. In the USA, the ATSDR has estimated that 46 % of the assessed National Priority List sites represent an actual hazard to health.13... 

According to recent epidemiological studies, the majority of cancer cases derive from environmental causes, whose factors are attributed to either the indoor environment or outdoor air pollution and soil contamination (Doll and Peto 1981). In deed, the relative risk of lung cancer mortality increases by some 8—27% in heavily polluted areas (Beeson et al. 1998). Ghazaouet city homes the complex of non-ferrous metals (En-Metanof) which uses the pyrometallurgical process. It uses 100000-115000 t/year of raw material for polymetallic sulphide (El Abed blend), and produces 30000-40000 t/year of Zn, 100-150 t/year of Cd and 50000-80000 t/year of H2SO4. 

One way to accept the proximity of nuclear energy and the risk that it poses to the population is to bring it back to the level of other pathogenic factors like the women who had several cases of cancer in her family, There have been three deaths already. Whether you live in Paris, Rouen or La Hague, it s the same The pollution is of a different nature, but its influence on health is as bad. The members of the family are touched by cancer victims who live in Paris, Rouen and La Hague. If someone considers leaving La Hague, I ask myself for what destination, because what place is free from pollution. In the same way, here, it is no worse than in the...
