Four thousand two hundred fifty-five cases of esophageal, stomach, colon, rectal, bladder, and pancreatic cancer reported from Erie County, NY between 1973 and 1976 were analyzed in terms of their relationship to type of water source, level of trihalomethane (THM) and various social and economic parameters. Among white males, a significant positive correlation existed between pancreatic cancer incidence rates and THM level. No other significant correlations were observed. This research lends little or no support to the hypothesis that THM levels which meet present standards are related to the incidence of human cancer.
对1973年至1976年间纽约州伊利县报告的4255例食管癌、胃癌、结肠癌、直肠癌、膀胱癌和胰腺癌病例,就其与水源类型、三卤甲烷(THM)水平以及各种社会和经济参数的关系进行了分析。在白人男性中,胰腺癌发病率与THM水平之间存在显著的正相关。未观察到其他显著相关性。这项研究几乎没有支持符合当前标准的THM水平与人类癌症发病率相关这一假设。
