四万居民按AFB_1摄毒量等级分三组,以同期饮水类型分为塘水和非塘水,以相对危险性(R.R)为主要评价指标.五年前瞻性观察结果:AFB_1高摄毒组居民患肝癌的相对危险性是低摄毒组的3.6倍,在饮塘水居民中,A7B_1高摄毒组是低摄毒组的4.7倍;在饮非塘水居民中,AFBI高摄毒组是低摄毒组的2.6倍。作者认为,AFB_1与塘水有协同致癌的作用,AFB_1单独致癌的可能性值得注意.
40,000 inhabitants were divided into three groups according to the AFB_1 intake level. The types of drinking water in the same period were divided into pond water and non-tank water. Relative risk (RR) was used as the main evaluation index. Five-year prospective observation results: AFB_1 high-risk group The relative risk of liver cancer among residents was 3.6 times that of the low-intoxication group. Among residents of Diantang water, the A7B_1 high-risk group was 4.7 times that of the low-risk group; in the non-tang water residents, the AFBI high-risk group It is 2.6 times that of the hypoxic group. The authors believe that AFB_1 has synergistic carcinogenic effects with pond water, and the possibility of AFB_1 carcinogenesis alone is worth noting.
