摘要:

目的:研究电子行业不同工种职业人群的DNA损伤情况,为确定健康危害预防重点提供依据。方法:选择珠三角某电子厂在职工人563名作为职业接触组,其中铅暴露组(n167),异丙醇组(n287),噪声组(n39),铅+高温组(n34),异丙醇+高温组(n36);选取就业前体检工人作为对照组(n90)。采集人体微量外周血进行彗星试验,运用倒置荧光显微镜拍摄彗星图片,并通过CASP彗星分析软件对彗星图片进行分析。结果:铅+高温组工人外周血的核DNA含量低于对照组(P<0.05),尾DNA含量、尾长和尾矩高于对照组(P<0.05);异丙醇+高温组工人外周血的核DNA含量低于对照组(P<0.05),尾DNA含量、尾长、彗星全长、尾惯量和尾矩高于对照组(P<0.05)。结论:本研究所选取的电子行业各工种工人均有明显的DNA损伤情况,尤以异丙醇+高温组工种最为严重,其次是铅+高温组工种,应引起职业病防治管理机构和厂方的特别关注。

Abstract:

OBJECTIVE: To evaluate the DNA damage of different sub-groups of workers in the electronics industry, and to set up major preventive measures. METHODS:The 563 workers of an electronics factory in the Pearl River Delta Region were studied, according to their jobs we divided them into 5 groups, including lead exposure group (n167), isopropyl alcohol group (n287), noise group (n39), lead+high temperature group (n34), and isopro-panol+high temperature group (n36), with 90 pre-employment workers as controls. DNA damage was detected using micro-whole blood specimen by the comet assay method. RESULTS:Nuclear DNA content of lead+high temperature group was lower than the control group (P<0.05), and its tail DNA content, tail length, and tail moment were higher than the control group (P<0.05). The nuclear DNA content of isopropyl alcohol+high temperature group was lower than the control group (P<0.05), the comet tail DNA content, tail length, comet length, olive tail moment and tail moment were higher than the control group (P<0.05). CONCLUSION:Workers of different types in electronics industry chosen in this study had obvious DNA damage, especially isopropanol+high temperature group, followed by lead+high temperature group, to which special attention should be paid to these.
