【摘要】：目的通過實(shí)驗(yàn)室間比對(duì)評(píng)價(jià)廣東省職業(yè)衛(wèi)生技術(shù)服務(wù)機(jī)構(gòu)檢測(cè)粉塵中游離二氧化硅的技術(shù)水平和能力。方法 2012—2015年分別在55、61、58和66家職業(yè)衛(wèi)生技術(shù)服務(wù)機(jī)構(gòu)開展粉塵中游離二氧化硅水平檢測(cè)的實(shí)驗(yàn)室間比對(duì),采用四分穩(wěn)健統(tǒng)計(jì)技術(shù)對(duì)檢測(cè)結(jié)果進(jìn)行統(tǒng)計(jì)分析,同時(shí)以實(shí)驗(yàn)室檢測(cè)結(jié)果與其中位數(shù)的相對(duì)偏差作為實(shí)驗(yàn)室技術(shù)能力的輔助評(píng)價(jià)指標(biāo)。結(jié)果游離二氧化硅水平20.00%的樣品的穩(wěn)健變異系數(shù)(CV)均低于5.00%,但游離二氧化硅水平≤20.00%的樣品的穩(wěn)健CV均大于5.00%。2012—2015年比對(duì)合格率分別為89.09%、81.97%、77.59%和81.82%;2012—2015年各年度民營(yíng)機(jī)構(gòu)和非民營(yíng)機(jī)構(gòu)比對(duì)結(jié)果合格率分別比較,差異均無統(tǒng)計(jì)學(xué)意義(P0.05);各年度珠江三角洲地區(qū)機(jī)構(gòu)與非珠江三角洲地區(qū)機(jī)構(gòu)的比對(duì)結(jié)果合格率分別比較,差異均無統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論定期開展粉塵中游離二氧化硅實(shí)驗(yàn)室間比對(duì)有助于提高職業(yè)衛(wèi)生服務(wù)機(jī)構(gòu)技術(shù)服務(wù)質(zhì)量。
[Abstract]:Objective to evaluate the technical level and ability of occupational health technical service institutions in Guangdong Province to detect free silica in dust by means of laboratory comparison. Inter-laboratory comparison of free silica levels in dust, Using the quadrature robust statistical technique to carry on the statistical analysis to the test result, At the same time, the relative deviation between the laboratory test results and its median was taken as the auxiliary evaluation index of laboratory technical ability. Results the robust coefficient of variation (CV) of samples with free silica level 20.00% was lower than 5.00, but free silica level was lower than 5.00%. The relative qualification rates of samples with level 鈮，
