Abstract

Volatile disinfection by-products (DBPs) contained in chlorinated tap water are released into household air during indoor activities (showering, cooking, dish -washing, etc.) associated with tap water uses and may cause adverse health effects on humans. Twenty seven subjects were recruited and their homes were visited during the winter of 2002. Tap water, household air, and exhaled breath samples were collected and analyzed for five volatile DBPs (chloroform, bromodichloromethane, dichloroacetonitrile, 1,1 -dichloropropanone and 1,1,1 trichloropropanone). Chloroform was a major DBP found in most samples. Tap water chloroform concentrations were not statistically correlated with its household air concentrations, probably due to individual variability in indoor activities such as showering, cooking, and dish - washing as well as household ventilation. Correlation of breath chloroform concentration with household air chloroform concentration showed its possible use as a biomarker of exposure to household air chloroform. Exposure estimates suggested that inhalation during household stay be a major route of exposure to volatile DBPs and that ingestion of tap water be a trivial contributor to the total exposure in Koreans.
