摘要
为了解山东省小麦镉和铬污染状况,选取山东省小麦主产区聊城茌平、菏泽郓城、德州齐河、泰安宁阳、临沂郯城、潍坊诸城、潍坊青州、滨州惠民、烟台莱阳共9个代表性区域种植的小麦籽粒,测定小麦中镉(Cd)和铬(Cr)含量,采用单项污染指数和综合污染指数法对小麦Cd、Cr污染进行评价。结果表明,山东小麦籽粒Cr平均含量和超标率均高于Cd,各采样区小麦Cd和Cr单项污染评价均为未受污染;潍坊诸城、临沂郯城、聊城茌平、德州齐河和烟台莱阳Cd和Cr综合污染评价为警戒水平,Cr为主要贡献因子,其他采样区域综合污染评价均为未受污染;菏泽郓城各项污染指数均最低。
The aim of this study was to find out the pollution status of cadmium（Cd） and chromium （Cr） in wheat grain in typical areas of Shandong province,and to provide a scientific basis for the safe production of wheat in Shandong province. The contents of cadmium and chromium in wheat grain were determined for samples collected from the representative area, such as Chiping of Liaocheng district, Yuncheng of Heze district, Qihe of Dezhou district, Ningyang of Taian district, Tancheng of Linyi district,Zhucheng of Weifang district, Qingzhou of Weifang district, Huimin of Binzhou district and Laiyang of Yantai district,and the pollution level of Cd and Cr in wheat grain was evaluated by single pollution index and comprehensive pollution index. The average content of Cr in wheat grain and over standard rate were both higher than those of Cd. The single pollution assessment of wheat Cd and Cr in each sampling area was below the pollution level, but Cd and Cr comprehensive pollution assessment was alert level for Zhucheng of Weifang district, Tancheng of Linyi district,Chiping of Liaocheng district,Qihe of Dezhou district and Laiyang of Yantai district, where Cr was the main contribution factor. The comprehensive pollution assessment of other sampling areas was below the pollution level. All pollution indices were the lowest for Yuncheng of Heze district.
