Organoarsenic compounds have been widely used as feed additives in livestock and poultry breeding. They are excreted in manure and thus cause environmental pollution. Moreover, organoarsenic compounds can be transformed into other arsenic species with higher toxicity. There is little knowledge on the transformation of organoarsenic compounds in the presence of iron species. Here, we studied the transformation of roxarsone (4-hydroxy-3-nitrophenylarsonic acid) in the presence of ferrous ion (Fe(II)) and tetrapolyphosphate. Various generated arsenic species were monitored. Results show that 94.8...
