Abstract: Because of the potential health and environmental risks of arsenic additives, it calls for more and more attention to strengthen the supervision over the use and control application of organic arsenic (As). This study investigated and analyzed the concentration of As in manure, and surrounding environment and their existing form at the outskirts of Beijing. The total As in collected litter samples from broiler and pig farms were ranged 0.16～2.20 mg/kg, that in soil was 0.80～9.55 mg/kg, and in water 0.08～23.14 μg/L.  The range of inorganic As in the litter, soil and water samples were 68.04～2 501.40 μg/kg, 429.15～2 836.77 μg/kg, and less than 13.50 μg/L, respectively. The investigation results indicated that As additives might not be used in these farms, indicating the management level of breeding industry have been continuously improved in this area. This study provided data for preliminary understanding about As polluted situation caused by animal husbandry in the suburb of Beijing.
