Trophic position and individual feeding habits as drivers of differential PCB bioaccumulation in fish populations
International audience Despite PCBs being banned since the 1980's, some European peri-alpine lakes, and consequently their fish populations, are still contaminated by these xenobiotics. We investigated the relative contribution of physiological and trophic factors that could be implicated in fi...
