摘　　要：对广州市白云区江高镇无公害蔬菜生产基地的水、土等环境要素，以及应市蔬菜中的有毒有害物质（如重金属、硝酸盐、有机氯农药等）进行了全面的监测分析。结果发现：部分监测点的土壤汞含量及蔬菜汞含量已达到国家规定的三级标准，属轻度污染；蔬菜硝酸盐的含量全部超过ＷＨＯ／ＦＡＯ的建议水平。但只要在生产过程中采取一定的防治措施。The environment of the harmless vegetable production area must conform to certain environmental quality standards, so the study of the environmental quality is the first step to produce vegetables. In some detected spots, it was found that the content of Hg in soils and the content of Hg and NO-3 in vegetables were higher than the standard values. However the area can still be used to produce harmless vegetables, as long as effective prevention measures are taken.
