摘　　要：开展了某地块土壤污染现状初步调查及异常点排查。结果显示,该地块所有检测项目的含量均低于规定的第一类用地风险筛选值。地块内有一个点位表层样品六价铬(0~0.5 m,4.6 mg/kg)为异常点,经异常点排查分析结果显示,该疑似异常点位对于本地块不具代表性,可予以排除。地块土壤基本没有受到地块内和周边区域历史上生产经营活动的影响。A preliminary investigation was conducted on the soil pollution status and abnormal points of a certain plot.The results showed that the content of all testing items in the plot was lower than the designated first category land risk screening value.There is a surface sample of hexavalent chromium(0~0.5 m,4.6 mg/kg)in the plot as an abnormal point.After investigation and analysis of the abnormal point,it was found that this suspected abnormal point is not representative of the local plot and can be excluded.The soil of the plot has not been significantly affected by the historical production and operation activities within and around the plot.

关 键 词：疑似污染地块 初步调查 异常点排查
