职业卫生检测实验室质量控制活动实施与结果评价

Effectiveness evaluation of practice of quality control for occupational health testing

    摘要
  • 摘要:
    目的 实施和评价职业卫生检测实验室的常见质量控制活动。
    方法 依据实验室质量控制的相关标准, 开展仪器比对、人员比对、留样复检、测量审核以及实验室间比对等, 根据结果对实验室进行评价。
    结果 仪器比对显示, 分别以MR-3A型和SFR-Ⅲ型辐射热计检测同一工作环境辐射热, 两者结果分别为(0.241 ±0.005) kw/m2和(0.246 ±0.004) kw/m2, 差异无统计学意义(P>0.05);人员比对显示两名技术人员对同批次活性碳管中苯含量检测结果分别为(589.4 ±3.0) mg/m3和(588.2 ±1.6) mg/m3, 两者差异无统计学意义(P>0.05);留样复检显示首次检测、留样复检同一滤膜中镉及其化合物, 结果分别为(0.312 ±0.007)μg/mL和(0.323 ±0.009)μg/mL, 两者差异无统计学意义(P>0.05);测量审核显示实验室测量有证标准物质结果为(0.247 ±0.009)μmol/L, 与证书参数(0.255 ±0.008)μmol/L相比, 差异无统计学意义(P>0.05);实验室间比对结果显示两实验室同时间进行同批号尿中铅质控物检测, 结果分别为(40.81 ±2.43)μg/L和(43.10 ±1.68)μg/L, 两者差异无统计学意义(P>0.05)。
    结论 多途径实施职业卫生检测常见质量控制活动并进行评价, 能多角度展现实验室检测工作质量状态, 是检测工作质量得到保证的最直接客观依据。

     

    Abstract:
    Objective To assess the effectiveness of practice of quality control for occupational health testing.
    Methods The instrumental comparison, personal comparison, sample re-examination, measurement auditing and inter-laboratory comparison were done and the data were analyzed, according to both the guidance on statistic treatment of proficiency testing results and performance evaluation and the guidance for measurement uncertainty evaluation based on quality control data in environmental testing.
    Results The heat radiation intensity was (0.241 ±0.005) kw/m2 measured with MR-3A and (0.246 ±0.004)kw/m2 measured with SFR-Ⅲ heat radiation meters (P>0.05), respectively. The benzene concentration was (589.4 ±3.0) and (588.2 ±1.6) mg/m3 (P>0.05), respectively, in the two activated carbon tubes used by two professionals. The cadmium concentration was (0.312 ±0.007) and (0.323 ±0.009)μg/mL (P>0.05), respectively, reported by sample re-examination. The measurement audit showed that content of a certified reference material was (0.247 ±0.009)μmol/L and there was no difference with the certificated parameter of (0.255 ±0.008)μmol/L (P>0.05). The measurement of urinary lead in two laboratories showed that the result was (40.81 ±2.43)μg/L and (43.10 ±1.68)μg/L (P>0.05), respectively.
    Conclusion Implementation of quality control for occupational health testing is effective and it is the objective evidence to preserve the laboratory with good reliability and applicability.
