This book covered a broad spectrum study of arsenic contamination in drinking and irrigated water and its impact on food crops and local community lived in arsenic affected areas of Pakistan. Speciation of arsenic in water samples was carried out by advance preconcentration methods for trace analysis. It is a first attempt to elucidate the chemical fractionation of geochemical bonded fractions of arsenic in soil and sediment. Moreover, the translocation of arsenic from growing media (irrigation water and soil)to local agricultural crops (grain crops and vegetables)was addressed well. The...
