摘　　要：目的分析职业卫生检测实验室对化学品中挥发性有机组分检测的比对结果。方法以参加广东省职业卫生检测中心组织的2019年全国职业卫生检验检测机构实验室间比对“化学品定性检测比对”的37家参比实验室为研究对象。推荐其采用顶空气相色谱-质谱联用法检测比对样品中的挥发性有机组分,收集参比实验室的比对结果分别进行定性和定量评价。结果各参比实验室必检危害因素、其他危害因素的定性结果合格率分别高于同类因素的定量结果(83.78%vs 67.57%,89.19%vs 56.76%,P值均<0.05)。各参比实验室必检危害因素与其他危害因素的定性、定量结果和综合判定结果的合格率分别比较,差异均无统计学意义(83.78%vs 89.19%,67.57%vs 56.76%,83.78%vs 89.19%,P值均>0.05)。37家参比实验室检测结果合格率为89.19%(33/37)。疾病预防控制系统与非疾病预防控制系统参比实验室的定性、定量和综合判定结果合格率分别比较,差异均无统计学意义(93.75%vs 85.72%,85.00%vs 61.91%,93.75%vs 85.52%,P值均>0.05)。结论各参比实验室化学品中挥发性有机组分检测能力存在较大差异,定性检测能力优于定量检测能力。Objective To analyze the comparison results of volatile organic components in chemicals tested by occupational health laboratories.Methods A total of 37 reference laboratories that participated in the 2019 National Occupational Health Inspection and Testing Institution Laboratory Comparison Chemical Qualitative Testing Comparison organized by Guangdong Occupational Health Testing Center were selected as the research subjects.Headspace gas chromatography-mass spectrometry was used for the determination of volatile organic components in chemicals.The comparison results of reference laboratories were collected and implemented with qualitative and quantitative evaluation.Results The qualified rates of the qualitative results of the required hazard factors and other hazard factors in the reference laboratories were higher than those of the quantitative results of similar factors with statistical significance(83.78%vs 67.57%,89.19%vs 56.76%,all P<0.05).There was no significant difference in the qualified rate of qualitative and quantitative results and comprehensive judgment results among each reference laboratory with other hazard factors(83.78%vs 89.19%,67.57%vs 56.76%,83.78%vs 89.19%,all P>0.05).The qualified rate of 37 reference laboratories was 89.19%(33/37).It showed no significant difference in the qualified rate of qualitative,quantitative and comprehensive judgment results among the reference laboratories of disease prevention and control system and non-disease prevention and control system(93.75%vs 85.72%,85.00%vs 61.91%,93.75%vs 85.52%,all P>0.05).Conclusion There are great differences in the detection ability of volatile organic components on chemicals of each reference laboratory.The ability of qualitative detection is superior to the quantitative detection.
