Regression of the log of the half-life of 16 persistent PCBs and log Kow in juvenile rainbow trout displays a curvilinear relationship. Compounds falling below this relationship (open circles), for example (+)-PCB 84 and (−)-PCB 132, are thought to be biotransformed. The solid line represents the quadratic regression line and the dashed lines represent the 95% confidence intervals. Reprinted with permission from (Konwick et al. 2006).
