The SCE frequency and cell cycle kinetics of 180 workers from a petrochemical corporation and 180 peoples from a control group were analysed.The results reveajed that there were no significant differences in SCE ferquency and in cell cycle kinetics between the two groups.However,the SCE frequencies of those workers in the two sewage treatment workshops (8.41±2.48,8.42±1.50) were significantly higher than both the control group (7.20±1.50) and the workers from the four production workshops (6.77±1.21).The duration...

The SCE frequency and cell cycle kinetics of 180 workers from a petrochemical corporation and 180 peoples from a control group were analysed.The results reveajed that there were no significant differences in SCE ferquency and in cell cycle kinetics between the two groups.However,the SCE frequencies of those workers in the two sewage treatment workshops (8.41±2.48,8.42±1.50) were significantly higher than both the control group (7.20±1.50) and the workers from the four production workshops (6.77±1.21).The duration of cell cycle in sewage treatment workers was also longer compared to that of workers from other workshops as well as the control group.It was shown that petrochemical substances may have certain cytogenetic effects on workers in a concentrati on dependent manner.

本文研究了180名某大型石油化工企业工人和180名对照组的SCE频率及其细胞Ⅰ、Ⅱ、Ⅲ周期的比率,结果表明,石化工人的SCE频率和细胞各周期比率与对照组无显著差异,即这两个地区由环境因子引起的这种细胞遗传效应差异不显著,表明它们有较相似的环境背景。但是,在石化企业中,两个污水处理车间工人的SCE频率明显地高于对照组和4个生产车间的工人,其细胞生长速率也明显地迟缓,揭示石化物质对人体有一定的细胞遗传效应,而且这种效应与人体所接触的石化物质浓度有关。

为了弄清低浓度苯环境下作业人群的健康状况,对某大型石油化工企业产生低浓度苯的5个车间采集323个样品分析。浓度范围在0.05~29.25mg/m3,其中制苯车间浓度最高,均值为4.57±6.16mg/m3;从5个车间筛选密切苯接触人群437人,选择非苯接触人群(对照组)150人,进行了外周血白细胞和淋巴细胞微核率的测定,结果表明:①外周血白细胞数虽在正常值范围之内,但非常显著低于对照组;②经常性苯接触工人淋巴细胞微核率分布高于非苯接触组,且制苯车间观察人群的淋巴细胞微核率与对照组比较,差异有显著性;③5个车间随作业环境苯浓度的增高,白细胞数有降低趋势,淋巴细胞微核率有增加的趋势。这些均证明低浓度苯对作业人群的健康有损害,尤其要注意对人体遗传物质的损伤作用。

为探讨石油化工生产中的有毒物质能否对女工生殖机能造成损伤,对某大型石油化工企业七个生产厂的2257名女工进行了月经及妊娠经过和妊娠结局的调查。结果表明:未婚女工月经经量异常及痛经患病率显著高于对照组(P<005)。已婚女工月经异常在各组间未见显著性差异。妊娠经过和妊娠结局的各项指标在接触和对照组间未见显著性差异。车间空气中绝大多数毒物年平均浓度未超过国家卫生标准,只有少数毒物浓度超标,但毒物浓度波动较大。该种作业环境尚未对女工造成明显的生殖损伤
