Les polychlorobiphényles : enjeux environnementaux et sanitaires, et mycoremédiation

Abstract : Polychlorinated biphenyls (PCB) are among the most widespread and persistent pollutants. These chemicals have been used for multiples industrial and domestic applications from the 1930s to the 1980s, especially for their great stability. They have been manipulated without precautions and then scattered in the ecosystems. Rivers from industrialized regions in the Post-war economic boom in Europe, United States of America and Japan are the most affected by this pollution. In France, the Rhône and the Seine are the most concerned. PCB presence in the environment poses a real health risk problem, due to the accumulation along the food chain. Their toxicity, related to dioxins, affects essentially neurodevelopment of children, causes hepatic, immune and endocrine disorders, and provokes cancers. Considering this environmental and health issues, the use of fungi liable to degrade PCB offers an advantageous alternative to physicochemical methods, with lesser environmental and economic impacts. Studies have indeed shown that in laboratory conditions, some ligninolytic fungi from Basidiomycota phylum, and filamentous fungi from Ascomycota and Zygomycota phyla, are able to degrade many PCB congeners in a liquid medium. However, the vast majority of the obstacle to mycoremediation development in historically polluted soil by PCB, is constituted by the use of model strains unsuited to polluted soil, and the lack of information about enzymatic mechanisms.
