广东省2012—2015年粉尘中游离二氧化硅水平检测实验室间比对分析
|
摘要
目的通过实验室间比对评价广东省职业卫生技术服务机构检测粉尘中游离二氧化硅的技术水平和能力。方法 2012—2015年分别在55、61、58和66家职业卫生技术服务机构开展粉尘中游离二氧化硅水平检测的实验室间比对,采用四分稳健统计技术对检测结果进行统计分析,同时以实验室检测结果与其中位数的相对偏差作为实验室技术能力的辅助评价指标。结果游离二氧化硅水平>20.00%的样品的稳健变异系数(CV)均低于5.00%,但游离二氧化硅水平≤20.00%的样品的稳健CV均大于5.00%。2012—2015年比对合格率分别为89.09%、81.97%、77.59%和81.82%;2012—2015年各年度民营机构和非民营机构比对结果合格率分别比较,差异均无统计学意义(P>0.05);各年度珠江三角洲地区机构与非珠江三角洲地区机构的比对结果合格率分别比较,差异均无统计学意义(P>0.05)。结论定期开展粉尘中游离二氧化硅实验室间比对有助于提高职业卫生服务机构技术服务质量。
Objective To evaluate the technical level and ability of the detection of free silica in dust in occupational health technical service institutions of Guangdong Province through inter-laboratory comparison. Methods The interlaboratory detection of free silica in dust in 55,61,58 and 66 occupational health technical service institutions were carried out and compared in 2012-2015. The results were statistically analyzed by four points robust statistical technique,and the relative deviation between the laboratory test results and the Median of them was used as the auxiliary evaluation index of the laboratory's technical ability. Results The stable coefficient of variation(CV) of samples with free silica content > 20. 00% was less than 5. 00%,and the stable CV of samples with free silica content ≤20. 00% was more than5. 00%. The qualified rate in 2012-2015 were 89. 09%,81. 97%,77. 59% and 81. 82%,respectively. There was no statistical difference(P > 0. 05) in the annual reference between private and non-private institutions compared to the qualified rate in 2012-2015. There was no statistical difference(P > 0. 05) in the qualified rate of the institutions in the Pearl River Delta region and in the non-triangular regions of the Pearl River Delta in 2012-2015. Conclusion Comparison of the detection technology service ability in the detection of free silica in dust should be conducted to improve its technical service quality.
