Concerns about ecotoxic side effects of the most commonly used sorbent, activated carbon (AC), on sensitive sediment-dwelling organisms were investigated using Lumbriculus variegates and river sediment polluted with PAHs to evaluate sorbent alternatives and magnetic sorbent recovery as potential engineering strategies to mitigate ecotoxic side effects. Magnetic biochar was identified as an effective PAH sorbent with fewer ecotoxic side effects than magnetic AC. After 85.1-100% magnetic recovery of this biochar, no measurable ecotoxic side effects on L. variegatus were observed in the treated sediment. Results show that ecotoxic effects of magnetic AC can be alleviated through sorbent recovery. This paper is Open Access at https://onlinelibrary.wiley.com/doi/full/10.1002/jctb.5224.
