摘要
目的调查同时接触丙烯腈、环氧乙烷、环氧丙烷和苯乙烯的聚醚作业人员职业健康状况。方法将某聚醚生产企业70名一线工人作为接触组，同一企业行政管理人员50人作为对照组，进行问卷调查、工作现场空气检测和职业健康体检，并对结果进行分析。结果同时接触丙烯腈、环氧乙烷、环氧丙烷和苯乙烯的接触组女工自然流产率、男工配偶自然流产率高于对照组，接触组血尿素氮异常率高于对照组，差异均有统计学意义（尸〈O．01）。不同接害工龄组DNA损伤定量分析的均数分布高于对照组，差异有统计学意义（P〈0．01）；工龄≥5，〈20年组和≥20年组微核率的均数分布高于对照组，差异有统计学意义（P〈0．01）。不同接害工龄组之间染色体总畸变率、DNA损伤定量分析的均数分布两两比较，差异无统计学意义（P〉0．05）；接害工龄≥5，〈20年组和≥20年组微核率的均数分布高于接害工龄〈5年组，差异有统计学意义（P〈0．01）。结论聚醚生产T人同时接触丙烯腈、环氧乙烷、环氧丙烷和苯乙烯对作业人员职业健康有影响。
Objective To investigate the occupational health of the workers simultaneously exposed to acrylonitrile, epoxyethane, epoxypropane, and styrene. Methods A questionnaire survey was conducted in 70 front-line workers simultaneously exposed to acrylonitrile, epoxyethane, epoxypropane, and styrene （exposure group） and 50 managers （control group） in a polyether manufacturer; in addition, air monitoring at workplace and occupational health examination were also performed. The obtained data were analyzed. Results The fe- male workers in exposure group and the spouses of male workers in exposure group had significantly higher spontaneous abortion rates than their counterparts in control group （P〈0.01）. The exposure group had a signifi- cantly higher abnormal rate of blood urea nitrogen than the control group （P〈0.01）. The workers with different polyether-exposed working years had significantly higher mean levels of DNA damage than the control group （P〈0.01）; the workers with not less than 5 and less than 20 polyether-exposed working years and those with not less than 20 polyether-exposed working years had significantly higher mean micronucleus rates than the control group （P〈0.01）; there were no significant differences in overall chromosome aberration rate and mean level of DNA damage between each two groups of workers with different polyether-exposed working years （P〉0.05）; the workers with not less than 5 and less than 20 polyether-exposed working years and workers with not less than 20 polyether-exposed working years had significantly higher mean micronucleus rates than those with less than 5 polyether-exposed working years （P〈0.01）. Conclusion Simultaneous exposure to acrylonitrile, epoxyethane, epoxypropane, and styrene causes occupational hazards among the workers in Dolvether manufacturer.
