Etude du miveau de contamination par les PCBs et les pesticides organochlorés de loutres (Lutra lutra) et l'anguilles (Anguilla anguilla) issues de zones humides de l'oeust de la France

Organochlorinated pesticides and PCBs were identified in 32 otter carcasses (road casualties) found in the wetlands of western France. The contamination levels are relatively low compared to those found in other otter European populations. As eel is the main prey of otters in that area, samples of that fish from the Marais poitevin were analysed too. They also show a low level of contamination by these compounds, their PCB congener pattern being different.
