Estimate the chronic daily intake of toluene from exposure to a city water supply that contains a toluene concentration equal to the drinking water standard of 1 mg/L. Assume the exposed individual is an adult female who consumes water at the adult rate for 70 years, that she abhors swimming, and that she takes a long (20 minute) bath every day. Assume that the average air concentration during the bath is 1 μg/m3. Assume that the dermal uptake from water (PC) is 9.0 x 10-6m/hr and that direct dermal absorption during bathing is no more than 80% of the available toluene because she is not completely submerged. Use the EPA lifetime exposure of 75 years. Express your answer in mg/kg-day. Which exposure pathway contributes the most to the chronic daily intake?
