氯化消毒(chlorination)是饮用水加工过程中使用最广泛的消毒方式。然而,氯化消毒过程中可产生对健康有害的物质一消毒副产物(disinfection byproducs,DBPs)。消毒副产物主要包括三卤甲烷(trihalomethanes,THMs)、卤代乙酸(haloacefic acids,HAAs)、卤代乙腈(haloaceton itriles,HAN)等。毒理学研究显示DBPs具有遗传毒性、致突变性、细胞毒性、生殖发育毒性和致癌性。膀胱癌是指发生在膀胱黏膜上的恶性肿瘤。是泌尿系统最常见的恶性肿瘤,也是全身十大常见肿瘤之一。有研究表明消化副产物的暴露与膀胱癌
Chlorination is the most widely used disinfection method in drinking water processing. However, disinfection byproducts (DBPs), substances harmful to health, can be produced during chlorination. Disinfection by-products mainly include trihalomethanes (THMs), haloacefic acids (HAAs), haloacetonitriles (HAN) and the like. Toxicology studies have shown that DBPs are genotoxic, mutagenic, cytotoxic, reproductive developmental and carcinogenic. Bladder cancer is a malignant tumor that occurs in the bladder mucosa. Is the most common malignant tumor of the urinary system, but also one of the top ten common tumors in the body. Studies have shown that the digestive by-product of exposure and bladder cancer
