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。
In view of the potential health and environmental risks associated with arsenic-containing additives and the monitoring of the use of organic arsenic, there is increasing demand to control the use of such arsenic-arsenicals. The contents of arsenic and their forms in the excrement and surrounding environment of Beijing suburbs farms were surveyed and analyzed. The total arsenic contents in the excreted pig farms and farms in Beijing were 0.16-2.20 mg / kg, the total arsenic range Was 0.80 ~ 9.55 mg / kg, the total arsenic range of water samples was between 0.08 ~ 23.14 μg / L. The range of inorganic arsenic in stool was 68.04 ~ 2 501.40μg / kg, the range of inorganic arsenic in soil was 429.15 ~ 2836.77μg / kg, and the inorganic arsenic in water was lower than 13.50μg / L. The survey results showed that the sampling farms may not use organic arsenic additives, indicating that the management of aquaculture in the region is constantly improving, providing preliminary data on the status quo of aquaculture in the region.
