Review of arsenic contamination, exposure through water and food and low cost mitigation options for rural areas

摘要: Abstract Arsenic (As) is a toxic metalloid found to be an important groundwater contaminant of mainly natural geogenic origin worldwide particularly in large deltas and along major rivers poor regions South- East-Asia. Excessive long-term human intake inorganic As with food water causing arsenicosis, which disfiguring, disabling, leading potentially fatal diseases like skin- internal cancers. It estimated that more than 100 million people developing countries are at risk. The arsenicosis situation affected has been named the largest chemical threat public health ever experienced spreading where near-sterile well loaded replaced microbial suspect surface containing lower concentrations. This review provides overview state art knowledge on exposure, how chemistry may influence chosen mitigation strategies. Although reports severe effects from exposure abundant there several weak points our causes prevalence order devise effective mitigation. main strategies focus drinking based exploration As-free removal extracted water, whereas cooking reducing through quite often overlooked. experiences adopted low cost methods for lowering rural areas critically evaluated terms acceptance, sustainability impact arsenicosis.
