Chromosome analyses were carried out in lymphocytes from 20 male papermakers exposed to formaldehyde (FA) for 2-30 years. 20 male workers from the same factory but without FA exposure served as controls. In the exposed group a significantly increased incidence of dicentrics or dicentrics and ring chromosomes was observed for 11 workers currently employed as supervisors. In contrast to 9 operators their total mean exposure time to FA was about 2.5 times longer. No significantly higher SCE values were found for smoking or for non-smoking FA workers compared with the corresponding control subjects.
对20名接触甲醛（FA）2至30年的男性造纸工人的淋巴细胞进行了染色体分析。选取同一家工厂的20名未接触FA的男性工人作为对照。在暴露组中，目前担任主管的11名工人的双着丝粒或双着丝粒和环状染色体的发生率显著增加。与9名操作员相比，他们接触FA的总平均时间约长2.5倍。与相应的对照对象相比，吸烟或不吸烟的FA工人均未发现显著更高的姐妹染色单体交换（SCE）值。
