在某蓄电池厂,对11名初次接触中等量铅蒸气的工人,进行了接触前和接触过程中的一系列染色体及生物化学的研究。工作一个月之后,以染色体丝及一次断裂(one-break)的染色体畸变为主要特征的中期有丝分裂异常率几乎增加一倍。工作两个月之后此比率进一步增加,直到接触的
In a battery factory, a series of chromosome and biochemical studies were conducted on 11 workers exposed to moderate amounts of lead vapor for the first time before and during exposure. After a month of work, the rate of metaphase mitosis, which is characterized mainly by chromosome filaments and one-break chromosomal aberrations, almost doubles. After two months of work this ratio increased further until it came into contact
