| 摘 要： | 采用田间采样和室内分析相结合的方法,对湖北省武汉、宜昌、荆门、荆州、恩施州、十堰、咸宁和黄冈共8个地区的45个主要蔬菜生产基地的pH和6种重金属(镉、汞、砷、铅、铬、铜)含量进行测定,再利用单项污染指数和综合污染指数评价方法,对土壤重金属的污染状况进行分析。结果表明,45个土壤样点pH范围为4.59~8.42,42.2%样点偏酸性;重金属含量均在《NY/T 391-2013绿色食品产地环境质量标准》限量标准以内,适宜发展绿色食品;单项污染指数表明黄冈市Cr、Cu和荆州市Cr单项污染指数超过0.7,临近警戒线;综合污染指数表明黄冈市重金属污染程度处于警戒线,其他地区均是安全的。

| Abstract: | The contents of pH and 6 kinds of heavy meta1s (Cd,Hg,As,Pb,Cr,Cu) on the growth of 45 major vegetab1e p1anting bases in eight urban districts of Wuhan,Yichang,Jingmen,Jingzhou,Enshi,Shiyan,Xianning and Huanggang of Hubei province were measured by fie1d samp1ing and indoor ana1ysis,and then the po11ution status of heavy meta1s in soi1 was ana1yzed by sing1e po11ution index and comprehensive po11ution index. The resu1ts showed that the pH va1ue of 45 soi1 samp1es ranged from 4.59 to 8.42 and 42.2% were acidic. The content of heavy meta1 was within the 1imits of NY/T 391-2013 green food origin environmenta1 qua1ity standards,which was suitab1e for the deve1opment of green food. The sing1e po11ution index showed that the individua1 po11ution index of Cr,Cu in Jingzhou city and Cr in Huanggang city exceeded 0.7, and near the warning 1ine 1eve1. The comprehensive po11ution index indicated that on1y the heavy meta1 po11ution 1eve1 in Huanggang was at the warning 1eve1, and other urban areas were safe. |
