The Sorption of Roxarsone, an Organoarsenical Animal Feed Additive
The organoarsenical roxarsone is added to poultry feed to increase weight gain. Studies have shown that roxarsone does not accumulate in poultry tissue but is excreted, resulting in elevated arsenic concentrations (~40 mg/kg) in poultry litter. However, there is little understanding of the fate of …

Adsorption Properties of Roxarsone and Arsenate on Goethite and Kaolinite
… study investigated the adsorption properties of roxarsone, an organoarsenic poultry feed additive, to goethite and kaolinite in order to determine what role mineral surfaces play in controlling the mobility of roxarsone in watersheds where poultry litter is applied. Adsorption edge experiments …

Arsenic uptake by beets (Beta Vulgaris) cultivated in a roxarsone-contaminated medium
… toxicant that negatively impacts human health. Roxarsone (ROX) is an organoarsenical administered to poultry to control internal parasites. ROX is excreted from poultry unchanged and the waste may be used for vegetable fertilizer. This experiment was conducted with beets (Beta vulgaris) by …

Factors Affecting the Toxicity and Metabolism of Organic Arsenicals (Roxarsone, Copper, Cysteine)
… and toxicity of the organic arsenical, roxarsone (3-nitro-4-hydroxyphenyl-arsonic acid). In experiments with chicks, cysteine enhanced the toxicity of the organic arsenicals, roxarsone and phenylarsonic acid. However, it had little effect on the toxicity of the inorganic arsenicals …

A Forty-Nine Day Evaluation of Bio-Mos® Replacement of Roxarsone in a Commerically Based Broiler Feeding Program
… was conducted to investigate the effects of roxarsone and Bio-Mos® on broiler production, gut morphology and bone strength. Three thousand and ten broilers were randomly assigned to 1 of 5 dietary corn-soybean meal based treatments: 1) negative control (NEG), basal diet; 2) positive control …

The Effect of Speciation and Form on the Bioavailability of Arsenic: Insight into the Behavior of Arsenic in Natural Waters
… As species, including As(III), As(V), MSMA, and roxarsone. Results showed variable response, with As(III) producing the strongest response, followed by As(V) and MSMA; roxarsone showed no response. The bioreporter was exposed to As solutions with varying cation concentrations to examine the …
