摘要： 调查分析了5年（2009—2013年）953个浙江省的有机肥料样品，结果表明，有机肥料样品中As，Hg，Pb，Cd，Cr总平均含量分别为9.53，0.42，31.80，1.25，71.00 mg·kg-1，均未超过NY 525—2012标准《有机肥料》规定的限量要求，但部分有机肥料样品中重金属含量超标，As，Hg，Pb，Cd，Cr超标百分比分别为18.3%，2.3%，9.0%，3.9%，5.2%。导致有机肥料中重金属含量超标的原因分两种，一种是符合有机肥料标准要求的原料中的重金属含量本身超标；另一种原因是不符合有机肥料标准要求的原料导致产品重金属含量超标。针对不同的原因，提出应采用的相应解决办法，确保有机肥料质量和安全。

Abstract: The experiment investigated 953 organic fertilizer samples in Zhejiang Province during 2009-2013. The results of investigation showed that average content of As， Hg， Pb， Cd and Cr in organic fertilizer samples was 9.53，0.42，31.8，1.25，71.0 mg.kg-1，respectively， which was below standard criteria. But the heavy metal contents in some samples exceeded standard requirements. The excessive percentage of As， Hg， Pb， Cd and Cr was 8.3%， 2.3%， 9.0%， 3.9%， 5.2%， respectively. There were two reasons for the presence of high heavy metal content in organic fertilizers. One reason was that heavy metal contents in raw material were out of limits. Another was that the raw materials were not accord with the standard. In order to ensure the quality and safety of organic fertilizer， we proposed some corresponding measures.
