摘　　要：为了解并改善饮用水质，在１９９１年第４季度至１９９３年第１季度，于某市水源水和水厂出厂水中采水样，每季度采集１次，每站位同时取两份，一份测定卤代烃的含量，一份用于处理蚕豆根尖并计数根尖细胞微核率。结果表明水厂出厂水中卤代烃含量比水源水的高，尤其是四氯化碳，各水厂出厂水中卤代烃的含量也有明显差异。发现水源水、水厂出厂水中四氯化碳含量与致突变有明显的相关性。ource water and outflow of waterworks were sampled every quarter from the fourth quarter 1991 to the first quarter 1993. Two samples were taken from each station, one for determination of CHCI_3, and CCI_4, and the other for treating of VICIA FADA root tip cell and counting the ratio of micronucleus of the root. It showed that the concentration of CHCI_3 and CCl_4 were higher in waterworks than in source water,especially for CCl_4. Differences of chloro-carbons concentration were found among waterworks. Significant relationship was demonstrated between the concentration of CCl_4, and the mutagenesis.
