Assessment of an NDL-PCBs Sequestration Strategy in Soil Using Contrasted Carbonaceous Materials through In Vitro and Cucurbita pepo Assays

The present study aims to assess the respective efficiency of Biochars (BCs) and activated carbons (ACs) limit PCB 101, 138, 153 180 transfer plants. A set 6 high carbon materials comprising 3 BCs ACs was tested used amend a soil at 2% rate. Then, two most efficient carbonaceous were as an amendment historically contaminated sampled in St Cyprien vicinity (Loire, France). An environmental availability assessment performed using ISO/DIS 16751 Part assay (n = 3). For vivo part, Cucurbita pepo grown for 12 weeks. Significant decreases found both assays notably powdered (up 98%). By contrast, significantly lower levels reduction observed when amendments performed, ranging from 27 80% 0 36% C. pepo. Reduction factors above 90% 2 selected amended soils. Present results led consider such sequestering strategy valuable ensure plant production on non-dioxin-like polychlorobiphenyls (NDL-PCBs)
