The Spatial Distribution and Potential Risk Assessment of POPs in Farmland around a Typical E-Waste Dismantling Site

Ferric Oxide Nanomaterials and Plant-Rhizobacteria Symbionts Cogenerate Iron Plaque for Removing Highly Chlorinated Contaminants in Dryland Soils

“…, no NMs or JD37 (group P); (2) 1000 mg/kg α-Fe 2 O 3 NMs (group F); (3) 1.5 × 10 9 CFU/plant JD37 (group J); and (4) 1000 mg/kg α-Fe 2 O 3 with 1.5 × 10 9 CFU/plant JD37 (group FJ). Each pot contained 2 kg of dry soil spiked with 0.5 mg/kg PCB101 based on the reported environmentally relevant concentrations. − In detail, a small amount of clean air-dried soil was homogeneously mixed with a stock solution of PCB101 prepared in acetone and then diluted using clean soil step by step to the required experimental concentration. The amended soil was stabilized for 7 days after sufficient watering.…”
