摘　　要：通过采集某铬渣堆场周边不同距离、深度的土壤和地下水样品,研究了铬渣堆场周边土壤、地下水中六价铬的分布特征和污染状况,通过数据分析确定了铬渣堆场周边受铬污染的地下水和土壤的范围及污染程度,判断污染边界,为后续场地污染治理提供了基础资料。结果表明:铬渣堆场周边土壤地下水已受到严重铬污染,必须尽快采取有效措施对其进行治理修复,以保证当地的农业生产和人体健康。Soil and groundwater samples in different distances and depth were taken from the surroundings of a chromium slag site to explore the Cr（Ⅵ） distribution and pollution characteristics. Based on large amount of data,the contaminating ranges and degrees of groundwater and soil were determined and the polluted boundary was confirmed,which provided basic data for the pollution treatment. The results demonstrated that the surrounding soil and groundwater of the chromium slag site were contaminated seriously by Cr（Ⅵ）. Effective measures should be taken as soon as possible to control pollution in the said site to ensure the local agricultural production and human health.
