Rapid economic development and industrialization have left many risk sites around the world with significant or potential soil contamination due to industrial production or the shutdown or relocation of industrial facilities.Soil pollutants pose significant threats to human health,especially at sites used by the chemical,mining,and metalworking industries,among others[1].Petro-chemical processing,coking,and nonferrous metal smelting are all important industries in China.Unfortunately,processes used in these industries generate a wide range of toxic pollutants including heavy metals and volatile organic compounds/semivola-tile organic compounds[2,3].As a result,34.9％ of these sites are contaminated by heavy metals including Pb,Cr,and As,as well as organic pollutants such as polycyclic aromatic hydrocarbons,at levels exceeding the upper limits stipulated in applicable regu-lations[4].These contaminants pose a risk to the health and well-being of people living nearby as well as to the nation\'s food security.At present,there are over 500,000 contaminated sites in China,affecting tens of millions of people[5].During the last dec-ade there have been several serious public safety incidents due to contaminants at such sites.

制定实验室检测的质量风险控制计划需要规划好检验流程图,并考虑到检验分析前、分析中和分析后阶段中的薄弱步骤,尽可能减少这些阶段中出现错误的可能性.质量风险控制计划可以在检验的过程中对这些薄弱点实施控制方案,以防止或改善错误检测,从而提高检测结果的整体质量.本文将对实验室风险来源进行分析,根据风险管理的相关理论,制定基于风险管理的实验室质量控制计划.
