As a hard working student you decide that you need to relax at the world renowned Ferguson Day Spa. After your massage you decide to use one of their ``therapeutic'' hot tubs. After some investigating, you find that the aqueous concentration of chloroform and trichloroethylene (TCE) in the hot tub water is 50 μg/L and 5 μg/L, respectively.
Chloroform and other trihalomethanes (THMs) are formed in water that is disinfected with chlorine. THMs are suspected carcinogens. Human exposure occurs when the water is ingested either directly or in a food or beverage product. Human exposure also occurs when THMs volatilize out of the water into the air and are inhaled, and when the skin is in contact with water or air containing THMs, especially during bathing. Wallace (1997) provides a recent summary of studies investigating chloroform intake.
The book "Exposure Analysis" (533p), edited by Wayne R. Ott, Anne C. Steinemann, and Lance A. Wallace, was published in 2007 by CRC Press, Boca Raton (Taylor & Francis Group). It is the first complete resource in the emerging scientific discipline of exposure analysis.
