本文报告火柴厂接触软木(杨木和椴木)粉尘的工人外周血淋巴细胞微核率的调查研究结果。调查了三个火柴厂接触木尘工人共298人,以45名宾馆服务人员为对照组,检测外周血淋巴细胞微核率。对照组外周血淋巴细胞微核率≥4‰的为2例(4.4%),故以≥4‰判为微核阳性。接触木尘工人微核阳性率为36.2%,与对照组阳性率(4.4%)
This paper reports the results of a survey of micronucleus frequencies in peripheral blood lymphocytes from workers exposed to dust in softwood (poplar and basswood) plants. A total of 298 workers exposed to wood dust were investigated in the three match factories, and 45 hotel service personnel were taken as the control group to test the micronucleus rate of peripheral blood lymphocytes. Control group, peripheral blood lymphocyte micronucleus rate of 4 ‰ for 2 cases (4.4%), it is judged as ≥ 4 ‰ micronuclei positive. The positive rate of micronucleus in workers exposed to wood dust was 36.2%, which was the same as that in the control group (4.4%)
