文摘

Biochar and CNT amendment reduced the bioavailability of HBCDs to earthworms. The reduction in HBCD bioaccumulation was greater in E. fetida than M. guillelmi. The amendments did not alter the isomer selectivity in HBCD bioaccumulation. HBCDs in soils resisted desorption, with Frap < Fslow. 24 h-desorption is a good proxy for the bioavailability of HBCDs to earthworms.
