“…O'Connor et al (2005) reported that dust in homes surrounding poultry operations contain 11-130 mg As/kg, which is higher than screening levels suggested by US EPA for industrial workers (3.8 mg As/kg). A speciation analysis showed that the house dust contained roxarsone, MMA, As(III), and As(V) along with several unidentified species.…”

“…Roxarsone, an organic acid feed additive, has historically been fed to broiler chickens to improve weight gain, feed consumption, and manage coccidial parasites (Chapman and Johnson, 2001). Because roxarsone is not metabolized by poultry and therefore does not accumulate in broiler meat, the bulk of roxarsone added to broiler feed is excreted in feces, which, when mixed with bedding, forms poultry litter (Anderson and Chamblee, 2001;O'Connor et al, 2005;Arai et al, 2003). Because poultry manure is rich in nutrients, >90% of poultry litter is land-applied as fertilizer (Jackson and Bertsch, 2001;Morrison, 1969;Moore et.…”

Occurrence of Arsenic and Phosphorus in Ditch Flow from Litter‐amended Soils and Barn Areas

et al. 2010

Little is known about the fate of arsenic (As) in land-applied litter from chickens that have been fed roxarsone, an organic feed additive containing As. This study seeks to elucidate the transfer of As in runoff from ditch-drained soils of the poultry-producing region of the Delmarva Peninsula by tracking As and phosphorus (P) export from seven drainage ditches over two water-years (1 July 2005 to 30 June 2007). Annual losses of As from ditches ranged from 0.004 to 0.071 kg ha(-1) while P losses ranged from 0.33 to 18.56 kg ha(-1), with the largest loads associated with a litter storage shed that served as a point source. Event-based As and P losses in ditch flow fluctuated by a factor of 162 and 1882, respectively. The two elements were correlated in flow from the ditch draining a litter storage shed (r = 0.99), and in sediment extracts in soils near the litter shed (r = 0.73), pointing to similar behavior under point source conditions. Indeed, As and P exhibited similar behavior within storms for all ditches, characterized by relatively high initial concentrations subject to rapid concentration declines before peak flow, consistent with dilution of a finite source. However, As and P concentrations varied significantly between ditches and showed considerable temporal variability within ditches, with no clear seasonal trends or associations with current management strategies. The results suggest that similar management strategies might be effective for As and P point sources, but that field management practices geared toward controlling nonpoint source P losses may not readily transfer to the control of As losses.

“…ROX is degraded rapidly during composting of litter, during storage and land application of litter, and in leachates from fields. Degradation products include inorganic As(V) and As(III), known to be the most toxic arsenic compounds, as well as a variety of organic arsenicals (O'Connor et al, 2005;Komorowicz and Baralkiewicz, 2011), depending on pH, redox conditions (Covey et al, 2010), interaction with minerals, and organic matter in soils and aquifer sediments (Brown et al, 2005). There are three main biotransformation processes of arsenic in the environment: redox transformation between As(V) and As(III), reduction and methylation of arsenic, and biosynthesis of organoarsenic compounds (Yaron et al, 2012).…”
