工作场所化学因素采样和检测的室间比对结果分析
|
摘要
目的通过分析工作场所化学因素采样规范性和检测准确性,提高采样和检测能力。方法收集本院2013~2015年参加工作场所化学因素现场采样和实验室检测相结合的室间比对结果,对采样流量核查、实验室检测和采样的规范性结果的合格情况进行评价。结果参加工作场所化学因素现场采样和实验室检测相结合室间比对项目共13项,总体合格率(优秀率)为76.9%(30.8%),不同年份的室间比对项目合格率(优秀率)分别为25.0%(0.00%)、100%(20.0%)和100%(75.0%)。采样流量核查项目5项,总体合格率(优秀率)为80.0%(40.0%);采样后样品实验室检测项目6项,总体合格率(优秀率)为66.7%(33.3%);采样的规范性项目2项,均合格。结论采样阶段加强质量控制是检测结果准确性的重要基础;参加工作场所化学因素现场采样和实验室检测的室间比对有利于提升职业卫生技术服务能力。
Objective To improve the capabilities of sampling and detection by analyzing the standardization of sampling and accuracy of detection of chemical factors in the workplace. Methods Collecting the data of the inter-laboratory comparison of sampling and testing of chemical factors in workplace in the past 3 years,analyzing the results of sampling flow verification,laboratory detection and sampling standard. Results A total of 13 items were conducted in the evaluation of the inter-laboratory comparison,and the general qualified rate( excellent rate) was 76. 9%( 30. 8%). The qualified rates( excellent rates) of inter-laboratory comparison items in different years were 25. 0%( 0. 0%),100%( 20. 0%)and 100%( 75. 0%). Totally 5 items of sampling flow verification were conducted,the general qualified rate( excellent rate) was 80. 0%( 40. 0%). Totally 6 items of laboratory detection were conducted,the general qualified rate( excellent rate) was 66. 7%( 33. 3%). Totally 2 items of sampling standard were conducted,the general qualified rate was 100%.Conclusion Strengthening the quality control from sampling phase is an important basis for the accuracy of the test results.Participating in the inter-laboratory comparison of sampling and testing of chemical factors in workplace could help to improve the occupational health technical service capabilities for the institution.
