An assessment of the amounts of arsenical pesticides used historically in a geographical area

The arbuscular mycorrhizal fungus Glomus mosseae gives contradictory effects on phosphorus and arsenic acquisition by Medicago sativa Linn

“…Elevated As concentrations in soils have been found in areas impacted by mining and smelting industries, and by coal burning throughout the world (Nriagu, 1994). The application of As-containing agrochemicals to domestic and agricultural land has also caused accumulation of As in soils (Woolson et al, 1971;Murphy and Aucott, 1998). Plant uptake of As from contaminated soils represents a significant pathway of human exposure.…”

Root distributions and elemental accumulations of Chinese brake (Pteris vittata L.) from As-contaminated soils

“…Elevated soil arsenic (As) levels by mining, pesticide and fertilizer applications, and coal combustion are frequently reported from around the world and in China (Phillips, 1990;Chen et al, 1992Chen et al, , 2002aLisk, 1994;Murphy et al, 1998). Arsenic is the second most common inorganic constituent after lead on the US EPA National Priority List, which includes an excess of 2000 contaminated sites that posed environmental health risks (Davis et al, 2001).…”

Determination of Arsenic in Environment by Spectrophotometric Technique using Hydroxamic Acids

“…Arsenic concentration in various water bodies is increasing day to day due to several reasons like use of arsenical pesticides, mineral dissolution, mine drainage, disposal of fly ash, and geothermal discharge [6]. Due to its high toxicity, World Health Organization (WHO) has lowered the maximum contaminant level (MCL) for arsenic in drinking water from 50 to 10 μgL -1 [7]. There are several accepted analytical methods currently available for arsenic measurement in environmental samples.…”
