【摘要】：鉴于含砷添加剂潜在的健康和环境风险,加强有机砷使用的监督、控制此类砷制剂应用的呼声越来越高。调查分析了北京市近郊养殖场的粪便废弃物及周围环境中砷的含量及存在形态,采集的北京近郊猪场和鸡场粪便总砷含量的范围为0.16~2.20 mg/kg,土壤总砷范围为0.80~9.55 mg/kg,水样总砷范围在0.08~23.14μg/L之间。粪便无机砷含量的范围为68.04~2 501.40μg/kg,土壤无机砷范围为429.15~2 836.77μg/kg,水样无机砷均低于13.50μg/L。调查结果表明采样养殖场可能未使用有机砷添加剂,说明本地区养殖业的管理水平在不断提高,为初步了解本地区养殖业对环境砷污染的现状提供了数据。
[Abstract]:In view of the potential health and environmental risks of arsenic-containing additives, there are more and more calls to control the use of organic arsenic. The contents and forms of arsenic in fecal waste and surrounding environment of Beijing suburb aquaculture farm were investigated and analyzed. The total arsenic content in feces collected from pig farms and chicken farms in the suburbs of Beijing was 0.16 ~ 2.20 mg / kg, total arsenic in soil was 0.80 ~ 9.55 mg / kg, and total arsenic in water samples was 0.0823.14 渭 g / L. The range of inorganic arsenic in feces was 68.04 ~ 2 501.40 渭 g / kg, soil inorganic arsenic was 429.15 ~ 2 836.77 渭 g / kg, and inorganic arsenic in water was lower than 13.50 渭 g / L 路kg ~ (-1) 路kg ~ (-1). The results show that the organic arsenic additive may not be used in the sampling farm, which indicates that the management level of the aquaculture industry in this area is constantly improving, which provides data for the preliminary understanding of the current situation of arsenic pollution caused by the aquaculture industry in this area.
