大约30年来，美国公共卫生服务局和美国环境保护局（USEPA）就饮用水处理中使用的聚电解质凝固剂产品的潜在健康影响提供了咨询意见。1990年4月，美国环保局将这个责任移交给由国家卫生基金会领导的组织。尽管美国环保局接受了1000多种聚电解质产品，但有证据表明，所代表的不同类型的聚合物化合物可能不到10到15种。环氧氯丙烷和丙烯酰胺等对健康有重大影响的污染物与这些产品配方有关。 表中列出了可用于饮用水处理的聚合物，并澄清了名称。列出了聚电解质产品中可能发现的污染物，以及聚丙烯酰胺产品中的杂质分析。讨论了一些特定的聚合物。包括68个参考文献、表格、图表。

For approximately 30 years, the US Public Health Service and the US Environmental Protection Agency (USEPA) offered advisory opinions on the potential health effects of polyelectrolyte coagulant products used in drinking water treatment. In April 1990, the USEPA transferred this responsibility to a consortium of organizations led by the National Sanitation Foundation. Although more than 1,000 polyelectrolyte products were accepted for use by the USEPA, evidence suggests that probably fewer than 10 to 15 different types of polymer compounds are represented. Contaminants such as epichlorohydrin and acrylamide, which are of significant health concern, are associated with these product formulations. Tables list the polymers accepted for use in drinking water treatment and clarify nomenclature. Contaminants that may be found in polyelectrolyte products are listed, as is an analysis of the impurities in a polyacrylamide product. A number of specific polymers are discussed. Includes 68 references, tables, figures.
