摘　　要：为了评价生物活性炭处理微污染原水的安全性,应用人类乳腺癌(MCF-7)细胞增殖试验和子宫增重试验进行测定。结果表明,水源水及生物活性炭进水提取物能刺激MCF-7细胞增殖,在原水量270mL和810mL时细胞增殖效应达到最大,生物活性炭出水提取物不引起MCF-7细胞增殖;水源水及生物活性炭进水提取物为5、25L·kg-1和25、125L·kg-1剂量组均刺激大鼠子宫生长,与对照组比较有统计学意义。生物活性炭出水提取物对子宫增重无影响,未表现出类雌激素活性作用。In order to evaluate the security of micro-polluted source water by biological activated carbon（BAC） process, MCF-7 cell proliferation assay and uterotropic assay were performed to detect the estrogen-like activity of the component of water. The results showed that the organic extract from source water and water of conventional drinking water processes stimulated the proliferation of MCF-7 cell. The dose inducing the maximum effect in cell proliferation assay was 270mL and 810mL. Organic extract from micro-polluted source water by BAC process did not stimulate the proliferation of MCF-7 cell. In uterotropic assay, doses of 5L·kg^-1, 25 L·kg^-1 and 25 L·kg^-1, 125 L·kg^-1 of organic extract from source water and water of conventional drinking water processes increased the weight of uterus of 21 day female rat significantly. Organic extracted frommicro-pollutedsouree water by BAC process did not exhibit the estrogenic effect.
