摘　　要：目的掌握顺义区电镀厂周边农作物铬污染现状。方法 2011-2013年对顺义区两个电镀厂周边农作物主要是根茎类蔬菜和粮食铬污染状况进行监测。结果获得监测数据144个,总体合格率为93.8%,2013年蔬菜铬污染水平最高。电镀厂周边1.5 km内农作物铬含量高于1.5 km外(P=0.039)。不同农作物富集系数不同,油菜、白菜和菜花富集系数较高,生菜、玉米和小麦次之,而萝卜、菠菜和柿子椒富集系数最低。结论应对重污染企业周边造成的污染状况进行严格监管,及时发现并排除隐患。同时在污染企业周边选择种植富集系数较低的作物,以提高作物品质。Objective To understand the current status of chromium contamination in agricultural products in area nearby electroplating factory in Shunyi District. Methods We sampled various agricultural products, including cereals and vegetables nearby electroplating factory between 2011 to 2013, to monitor the contamination of heavy metal chromium in agricultural products.Results We obtained the monitoring data of 144, the overall pass rate was 93.8%. The highest level of chromium pollution was in vegetables in 2013. The pollution levels within 1.5km around factory were higher than above it（P=0.039）. The enrichment coefficients of different crops were different. Rape, cabbage, cauliflower, enrichment coefficients were the highest, followed by corn,wheat and lettuce. Radish, spinach, and capsicum enrichment coefficients were minimum. Conclusion Heavy pollution enterprises should be supervised strictly, hidden dangers should be found and eliminated timely. At the same time, we should select the lower enrichment coefficient crops and plant in pollution enterprises, to improve the quality of crops.
