“…Sequential extraction technique has been widely used to assess the geochemical partitioning and chemical binding of As in solids (Han et al 2004;Devesa-Rey et al 2008;Doušová et al 2008;Qi and Donahoe 2008;Costagliola et al 2013;Kim et al 2014), and to evaluate adsorption fraction and desorption (Zhang and Selim 2005;Osorio-López et al 2014). This method offers a great promise to distinguish effects of interacting factors and to understand the roles of the interacting factors in chemical binding of adsorbed As.…”

“…Availability, toxicity and mobility of As in soil-waterplant systems are largely determined by the speciation and distribution, or partitioning of As between the solution and soil matrix (Han et al, 2004). Table 3 shows the distribution of labile As (soluble + exchangeable As forms) at three different time periods: time-0 (immediately after spiking), time-mid (after leaching) and time-final (6 months after soil-pesticide equilibration).…”

“…Roxarsone, an organo-arsenical, is currently used as a feed additive in the diets of chickens and swine to improve growth and feed efficiency and to prevent coccidial infections (Han et al 2003). The compound is excreted in animal waste and degrades to arsenite and arsenate (leachable forms of arsenic).…”

“…Studies of poultry litter have found that 70 to 90% of the total arsenic in litter is water soluble Jackson et al 2003). Levels of arsenic in poultry litter are roughly ten times higher than those found in biosolids (Han et al 2003). The USGS has calculated, based on arsenic concentrations measured in poultry waste, that between 250,000 and 350,000 kilograms of arsenic (from poultry feed additives) is applied annually to land in the US .…”
