Analysis of accumulation, extractability, and metabolization of five different phenylarsenic compounds in plants by ion chromatography with mass spectrometric detection and by atomic emission spectroscopy

Organoarsenicals in poultry litter: Detection, fate, and toxicity

“…Organoarsenicals have been detected in solid media, such as animal litter (Jackson and Bertsch, 2001;Garbarino et al, 2003;Rosal et al, 2005;Yao et al, 2009a;D'Angelo et al, 2012), agricultural soils (Woolson, 1975;Covey et al, 2010;Liu et al, 2013;Yao et al, 2013b); liquids like agricultural runoff , groundwater (Daus et al, 2008;Hempel et al, 2009), and urine/blood of animals (Overby and Fredrickson, 1965;Xie et al, 2006); and biological tissues (Croteau et al, 1994;Dean et al, 1994;Schmidt et al, 2008;Monasterio et al, 2011;Conklin et al, 2012). Extraction of organoarsenicals from environment samples must ensure high recovery without compromising the arsenic speciation chemistry (i.e., organic vs. inorganic).…”

Speciation analysis of organoarsenic compounds in livestock feed by microwave-assisted extraction and high performance liquid chromatography coupled to atomic fluorescence spectrometry

“…Different separation techniques, including high performance liquid chromatography (HPLC), gas chromatography (GC) and capillary electrophoresis (CE) coupled with inductively coupled plasma mass spectrometry (ICP-MS) (Conklin, Shockey, Kubachka, Howard, & Carson, 2012;L. Liu, He, Yun, Sun, & Jiang, 2013;Mao, Chen, Huang, He, & Hu, 2011;Schmidt, Kutschera, Mattusch, & Otto, 2008;Sierra-Alvarez et al, 2010;P. Wang, Zhao, Tian, & Su, 2010) and atomic absorption or fluorescence spectrometry in combination with hydride generation (HG-AAS and HG-AFS) (Hagiwara, Inui, Koike, & Nakamura, 2013;J.…”

“…HG-AFS has some additional advantages for As speciation analysis, including simplicity, as well as lower acquisition and operating costs. Different HPLC separation modes, such as ion exchange (IE) (Conklin et al, 2012;Schmidt et al, 2008), reversed phase (RP) (Cui et al, 2012), and reversed phase ion pairing (RP-IP) (Mao et al, 2011;Monasterio et al, 2011;P. Wang et al, 2010), have been employed for As speciation in feed additives.…”

Uptake and transport of roxarsone and its metabolites in water spinach as affected by phosphate supply

“…1). It is documented that ROX can be absorbed and transformed by Tropaeolum majus grown in soil irrigated with ROX solution [13]. However, it is difficult to identify whether this species of water spinach could take up ROX, because ROX might be converted to other As forms in the tissues in the course of the experiment.…”
