Comparison of High Molecular Weight Organics Isolated from Drinking Water in Five Cities

摘要

Since the previously unidentifiable non-volatile fraction of the chlorinated organics in drinking water is of significant health concern, the physical and chemical characteristics of the high molecular weight organics isolated from drinking water in five cities (New Orleans, Philadelphia, Miami, Seattle, and Ottumwa) were compared. From the results of the study, they may be considered as part of a single group of natural organic compounds. Although the respective molecular structures of the group of compounds are still unknown, they showed, however, great similarities in terms of molecular, solubility and functional group among the samples collected from the five cities. This indicates that it is probably acceptable to base results of toxicological testing on chlorinated organics from a limited number of drinking water sources.
