Title: Determinants of Short-Term Exposure to Trihalomethanes in the Household
Investigators: Miles, Amy M.
Institution: University of North Carolina at Chapel Hill
EPA Project Officer: Jones, Brandon
Project Period: August 1, 1999 through August 1, 2002

Research Category: Academic Fellowships , Engineering and Environmental Chemistry , Fellowship - Civil/Environmental Engineering



The objective of this research project is to determine the water-use activities and physical factors that dominate trihalomethane (THM) concentrations in the blood.


Methods will include: (1) establishing the relative contributions of residential water-use activities to THM concentrations in the blood through a controlled exposure experiment; (2) examining the effect of variability in water-use activities (i.e., water temperature, duration, and flow rate) on indoor-air concentrations and exposure; (3) measuring the concentrations of THM in indoor air and comparing the distribution of THMs to that measured in tap water; and (4) characterizing volatilization from sources other than showers and validating an existing indoor-air model.
