The effects of chronic arsenic exposure from drinking water on the neurobehavioral development in adolescence. 08-24-2003 This cross-sectional study examined the possible influence on the development of cognitive function among adolescents due to long-term arsenic exposure. Forty-nine junior school students drinking arsenic-containing well water and 60 controls matched with age, sex, education, body height, body weight, body mass index, and socioeconomic status were compared. Arsenic pollution in groundwater: a self-organizing complex geochemical process in the deltaic sedimentary environment, Bangladesh. 09-01-2003 The presence of considerable concentrations of As (Sonargon: below detection limit (bdl)-1.46 mg/l; Faridpur: bdl-1.66 mg/l) and some other elements (like B, F, U) in groundwater of the Ganges-Meghna-Brahmaputra (G-M-B) rivers flood plain indicate that several millions of people are consuming contaminated water. Conditions regulating the mobilization and diagenetic behavior of arsenic in sediments are not well characterized, although understanding these conditions is essential in order to predict the modes of transfer of this contaminant from sediments to groundwater
