TITLE Aa. Examine the effects of arsenic as a soil pollutant on human health. It is necessary to consider the main sources of arsenic (both natural and man-made), the routes of absorption by people and the impacts on human health. Soil pollution due to arsenic (As) has attracted much attention in recent years due to its threat to human health and adverse effects on animal and plant growth (Duker et al, 2005; Williams et al., 2005 ). Volcanism releases arsenic into the air which is brought to the earth's surface by rainwater and contaminates the soil. Arsenic is also produced by the weathering of arsenic-containing ores and ores and by commercial or industrial processes. Arsenic (As) is a lethal metalloid found in rocks, sediments, water, soil and air. It enters terrestrial and aquatic ecosystems through a combination of natural processes such as volcanism, weathering, and biological activity, as well as the result of anthropogenic (human-made) activities. Excessive use of As-based pesticides, fertilizers or herbicides, wood preservatives, arsenic additives in pet feed, pharmaceutical companies, electronics industries, munitions factories, and coal or oil galvanization and incineration (Simith et al., 1998 :Matschullat, 2000) and indiscriminate disposal of industrial and domestic wastes (sewage), as well as mining activities, have resulted in extensive arsenic contamination in soil/terrestrial ecosystems and attracts worldwide attention mainly due to its undesirable impact on human health (Lee et al., 2008 ; Duker et al., 2005; Liao et al., 2005 Liu et al., 2005). .. in the inhabitants who live near smelters and arsenical chemical factories. Citizens living near arsenic dumps may have a higher risk of lung cancer. Direct skin contact with the high concentration of inorganic arsenic compounds found in the soil can cause skin irritation with swelling and redness. However, it does not appear that direct contact with the skin can cause serious internal infections. There is almost no data available on the effects of organic arsenic compounds on humans. Animal research shows that simpler organic arsenic compounds (such as methyl and dimethyl compounds) are less lethal than inorganic forms. In animals, intake of methyl compounds can cause diarrhea, and lifelong disclosure can damage the kidneys. Permanent contact with dimethyl compounds can damage the urinary bladder and kidneys.
