Arsenic: Human Exposure and Impact on Environment

Main Article Content

Dr. Gargee Yadav Yadav


Arsenic is a naturally occurring metalloid and is highly toxic in its inorganic form. It is a component of earth’s crust and is distributed widely throughout the environmental resources such as water, air and land. Owing to its toxic nature, exposure to arsenic can be hazardous and is reported to be a confirmed carcinogen and a significant risk factor for cancer. The human exposure to arsenic can be attributed to contaminated air or drinking water, certain foods, cigarette smoking and occupational environment. A great threat to human health maybe posed by the arsenic-contaminated water used for irrigation of food crops, drinking and food preparation. However, drinking water remains the major source of arsenic poisoning worldwide. Arsenic in drinking water in its inorganic form and is reported to be absorbed and metabolized easily, thus posing a serious health hazard. However, arsenic content found in sea foods is organic in form and is comparatively less harmful. Long term exposures can result in chronic arsenic poisoning, leading to skin lesions and skin cancers as reported by various studies. WHO has listed arsenic as one of 10 chemicals posing public health concern. Therefore, a thorough knowledge of nature, sources, and effect of arsenic on human health as well as environment is imperative.
