广西环境检测实验室土壤重金属检测能力验证

摘要

【目的】了解广西环境检测实验室检测土壤中重金属砷(As)、铅(Pb)、镉(Cd)、汞(Hg)的能力。【方法】采用分割水平对样品进行检测,并利用四分位稳健统计方法对广西33个实验室的检测能力进行评价。【结果】32家实验室完成汞、铅、镉、砷4个项目的检测,1家实验室完成铅、镉2个项目的检测。砷的检测满意率81.3%,铅的检测满意率75.8%,镉的检测满意率66.7%,汞的检测满意率71.9%。32家完成4个检测项目的实验室中有18家检测结果满意,满意率56.25%。【结论】广西环境检测检测实验室具备较好的土壤重金属检测能力。%[Objective]To understand Guangxi environmental laboratorial capabilities of testing heavy metals such as Arsenic,Lead,Cadmium and Mercury.[Methods]With split level sam-ple design and robust statistics,33 laboratories’testing capabilities were evaluated.[Results]32 laboratories had completed the testing for Mercury,Lead,Cadmium and Arsenic,and 1 laoratory had completed the testing for Lead and Cadmium.The satisfaction rates of heavy metals testing were:81.3% for Arsenic,75.8% for Lead,66.7% for Cadmium and 71.9%for Mercury.18 of 32 laboratories which completed 4 testing items were evaluated as satisfac-tion,and the satisfaction rate was 56.25%.[Conclusion]Guangxi environmental testing labo-ratories had decent capabilities of testing heavy metals.
