土壤污染状况初步调查技术要点

Key Technical Points for Preliminary Investigation of Soil Pollution Status

土壤污染状况初步调查工作内容是确定地块是否被污染,并通过采样分析了解地块的污染程度和范围。采样分析过程应可追溯,整个调查过程都应实事求是地反映出地块的污染状况。地块历史变迁应叙述清晰,过程中地块如有污染,则应准确识别出特征污染因子,土壤、地下水样品采集分析过程中应采取质控手段,测试分析应科学、精准。在土壤污染状况初步调查实践中总结出一些技术要点,为从事场地污染调查的人员提供参考。

The content of the preliminary investigation of soil pollution was to determine whether the plot was polluted and understand the pollution degree and scope of the plot through sampling and analysis.The sampling and analysis process should be traceable,and the entire investigation process should truthfully reflect the pollution status of the plot.The historical changes of the plot should be described clearly.If there was pollution in the process,the characteristic pollution factors should be accurately identified.Quality control measures should be taken during the collection and analysis of soil and groundwater samples,and testing and analysis should be scientifically accurate.In the preliminary investigation practice of soil pollution,some technical points have been summarized,which provides certain guidance for personnel engaged in site pollution investigation.
