为了解橡胶制品生产中排放废气物对居民染邑体略变的影响，采用ＷＨＯ推荐的微量血培养方法和Ｂｕｃｋｔｏｎ外周血淋巴细胞染色体畸变分类法，对居住于包头橡胶制品厂下风向居民区居民４０例和上风向居民区居民４８例进行了外周血淋巴细胞染色体畸变调查。调查结果显示：两组之间细胞染色单体畸变率、染色体畸变率及细胞总畸变率的差异均有统计学意义（Ｐ＜０．０１）；不论是调查组还是对照组，细胞染色单体畸变率、染邑体畸变率及细胞总畸变率男女性别之间差异均无统计学意义（Ｐ＜０．０５）；细胞染色体畸变百分比构成以染色体断裂畸变为主要类型，调查组和对照组分别为７２／和７３／。结果提示：下风向居民细胞染色体畸变率偏高可能与橡胶厂废气排放有关。
In order to understand the impact of exhaust emissions on the dyeing of residential residents in the production of rubber products, the WHO recommended micro-blood culture method and Buckton’s chromosome aberration classification method for peripheral blood lymphocytes were applied to residents living in downwind residential areas in Baotou Rubber Products Factory. 40 cases and upwind residential residents 48 cases were investigated for peripheral blood lymphocyte chromosomal aberrations. The results of the investigation showed that there were significant differences in cell chromatid aberration rate, chromosome aberration rate, and total cell aberration rate between the two groups (P<0.01); whether in the investigation group or the control group, cell chromatids There was no statistically significant difference in male and female genders in terms of the rate of aberrations, the rate of lesions and total aberrations (P<0.05); the percentage of chromosomal aberrations constituted the main type of chromosomal aberration, and the investigation group and the control group respectively. 72/and 73/. The results suggest that the high chromosomal aberration rate of downwind residential cells may be related to exhaust emissions from rubber plants.
