Special Issue Information

Dear Colleagues,

 

Today, humans are exposed to environmental contaminants—deposited in environmental matrices due to different emission sources—through multiple pathways. There is a real risk that they can enter the food chain and may harm human health. Although reducing the emission of such contaminants is and will always be the goal, we have to find ways to cope with their presence in our environment, making sure to protect the aquatic as well as terrestrial food chain. Numerous scientists are working to understand the mechanisms that link these compounds more or less strongly to environmental issues. Others are studying the mechanisms that regulate their uptake by organisms. Some research teams are trying determine means to reduce or completely avoid such uptake by modulation of their bioavailability via different chemical or physical techniques.

I would like to invite you to contribute your work to this Special Issue, with the aim of compiling current knowledge about this topic.

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