××化工厂聚氯乙烯车间,1973年8月正式投产。车同空气中氯乙烯浓窿一般均超过最高容许浓度。 1980年在该厂调查该作业已婚工人71人,以本厂机械车间工人作对照。为了避免氯乙烯大气污染的影响,又在距离该厂十里以外××机械厂工人作为厂外对照组。为丁明确氯乙烯对职工子女的影响。在聚氯乙烯车间调查的工人及其子女,将其子女按父母情况分为孕期接触氯乙烯组44人,孕期未接触氯乙烯组27人。在孕期接触氯乙烯组中发现先天性缺陷子女6人,总计发生率为76％。厂内厂外对照组均无类似发现,经统计学处理有显著差别(P<0.05)。
× × Chemical Plant PVC plant, formally put into operation in August 1973. Vehicles with vinyl chloride air in the hole are generally exceeded the maximum allowable concentration. In 1980, 71 workers at the factory were surveyed for the job and the factory workers in the workshop were used as controls. In order to avoid the impact of vinyl chloride air pollution, but also away from the plant outside the × × Machinery Factory workers outside the factory as a control group. To clarify the impact of vinyl chloride on workers and children. Workers and their children surveyed in the PVC workshop divided their children into 44 pregnant women exposed to vinyl chloride during pregnancy and 27 pregnant women without exposure to vinyl chloride during pregnancy. In pregnancy contact with vinyl chloride group found 6 children with congenital defects, the total incidence of 76%. There were no significant differences between the control group and the control group (P <0.05).
