2. 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 of toluene during the bath is 1 µg/m3. assume the dermal uptake from water (pc) is 9.0 x 10-6 m/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.'
