摘要： 为分析北京地区规模化养猪场粪便中四环素类抗生素和重金属残留现状，随机选取京郊35家规模化养猪场粪样进行了检测分析。结果表明：北京地区猪粪中四环素、土霉素和金霉素检出率分别达到90.9%、45.5%和18.2%，四环素类抗生素合计浓度范围为0.48~29.2 mg/kg，其中约27%的样品达到可造成土壤环境风险临界值；猪粪中砷、镉、铬和铅的平均质量分数分别为2.9、0.3、11.6、0.3 mg/kg，均符合有机肥料标准限值要求；猪粪中铜和锌超标现象仍然较为普遍，可能造成累积性环境风险。

Abstract: Sampling analysis of solid pig feces from 35 large-scale pig farms in Beijing Area was carried out for the purpose of investigating the tetracyclines and heavy metals residues. The results showed that the detection rates of tetracycline, oxytetracycline and chlortetracycline in pig feces were 90.9% , 45.5% and 18.2%, respectively. The concentration range of 4 tetracyclines in pig feces was 0.48 to 29.2 mg/kg. 27% of the samples were estimated to be risky while being applied to the cropland as organic fertilizer. The average amount of total As, Cd, Cr and Pb in pig feces were 2.9, 0.3, 11.6 and 0.3 mg/kg, respectively, which complied with the national standard of organic fertilizer in China. But the high concentration of Cu or Zn and their possible environmental risks should not be neglected.
