Schematic overview of how the CoZMoMAN model estimates CBATs for PCB-153: historical atmospheric emission estimates (A; adapted from Breivik et al. 2010) are used to derive time trends in the concentrations in air and water (B) using a physical environmental fate model. These concentrations in exposure-relevant environmental media, as well as assumptions concerning dietary composition (C) and growth curves for these women (D; adapted from Czub and McLachlan 2004), are used to calculate LBATs for women born every 5 years (E) using a human food chain bioaccumulation model. Finally, CBATs for 1968, 2000, and 2030 are obtained by “sampling” the women whose LBATs had been estimated. ww, wet weight.
