作者对一家汞锌合金工厂的20名工人(汞接触者和对照各10名)和一家氯碱工厂的27名工人(汞接触者12名和对照15名)进行了外周血淋巴细胞染色体畸变率的研究。汞接触组和对照组平均年龄相近,吸烟者和近12个月内有过x线接触的比例亦相近。 接触工人尿汞(μg/每克肌酐)为8.2～286(平均117),血汞(μg/100ml)0.75～10.52(平均3.06);对照组尿汞和血汞分别为<5μg/每克肌酐和0.6μg/100ml。接触组平均汞接触年限4年(0.3～15.3年)。
The authors performed a study of chromosome aberration rates in peripheral blood lymphocytes in 20 workers at a mercury-zinc alloy plant (10 mercury contacts and 10 controls each) and 27 workers at a chlor-alkali plant (12 mercury contacts and 15 control subjects) . The average age of mercury exposure group and control group were similar, and the proportion of smokers who had x-ray exposure in the past 12 months was also similar. Urinary mercury and blood mercury levels in exposed workers were 8.2 to 286 (mean 117) and 0.75 to 10.52 (μg / 100ml) for exposed workers, respectively; And 0.6 μg / 100 ml. The contact group average mercury exposure period of 4 years (0.3 ~ 15.3 years).
