Normalized mean CHCl3 concentrations in air (A) and exhaled breath (B) for subjects at both sampling sites as a function of various common household water-use activities (mean ± SE). All activities in air (except for dishwasher open and postsecondary shower exposure) were measured during the exposure. For all activities, exhaled breath (except during automatic dishwashing and during secondary shower exposure) was measured 5 min after the exposure ended.
aNo air sample was collected for this activity.
