Using this unique temporal sampling design, PRC results from each deployment were fit to a diffusion model to estimate the Cfree of 27 PCB congeners and compare the results between the different deployment times. Smaller PCBs had variable concentrations over the four deployments while mid-molecular weight PCBs had consistent Cfree measurements for all deployments (relative standard deviation less then 20%). High molecular weight PCBs had the largest Cfree estimates after 30 days, these estimates and their standard deviations
