对石油化工企业工人(180人)及非石化企业对照人群(180人)进行染色体畸变的检测,结果表明:(1)石化地区居民染色体畸变频率略高于非石化地区居民,但无显著性差异。(2)石化企业中,炼油厂污水处理车间和塑料厂污水处理车间工人的染色体畸变各项指标和对照组比较(除塑料厂污水处理车间工人的染色体畸变一项指标外)或与其它4个车间(苯酚丙酮、催化裂化、乙二醇和丁二烯)比较,都有显著或极显著的升高。4个车间分别和对照组比较,没有显著升高。(3)染色体畸变频率有季节变化,春秋季明显高于冬季和夏季。(4)对照个体中,不同性别、不同年龄组及吸烟与否,对染色体畸变的各项指标均无显著性差异。但在石化企业不同年龄工人染色体畸变率的比较中,大于或等于40岁的工人组,明显高于30岁以下各组。
The results showed that: (1) The frequency of chromosome aberration in residents of petrochemical industry was slightly higher than that of non-petrochemical residents, but there was no significant difference . (2) Among the petrochemical enterprises, the indexes of chromosome aberration of the workers in the refinery wastewater treatment workshop and the plastic factory wastewater treatment workshop were compared with those of the control group (except for the index of chromosome aberration of the workers in the wastewater treatment plant in the plastic factory) or with other 4 The workshop (phenol acetone, FCC, ethylene glycol and butadiene), there is a significant or very significant increase. 4 workshops were compared with the control group, there was no significant increase. (3) There is a seasonal change in the frequency of chromosome aberrations, which is obviously higher in spring and autumn than in winter and summer. (4) There was no significant difference in the indexes of chromosome aberration in the control subjects among different sexes, different age groups and smoking or not. However, in the comparison of the chromosome aberration rates of workers of different ages in petrochemical enterprises, the workers in the group of 40 or older were significantly higher than those in the group of those under 30 years of age.
