Intracellular Arsenic Speciation and Quantification in Human Urothelial and Hepatic Cells

摘要: Arsenic can be found in nearly every part of the geosphere. It is viewed as most harmful toxin drinking water worldwide. At many places on earth contains concentrations above 10 μg/l, which significantly exceed tolerable value recommended by WHO (World health organization [WHO], 2001). This considered a threat for millions people, especially Bangladesh, Vietnam, and Latin America, where geogenic origin has already been proved (Ng et al., 2003). The sources this considerable arsenic occurrence (Fig. 1) are (erosion), mining activities, geothermal waters (Smedly & Kinniburgh, 2002).
