| Abstract: |
| Hexabromocyclododecane(HBCD) is a widely used additive in brominated flame retardants(BFRs) and is known to be persistent, bio-accumulable, toxic to ecosystems, and capable of being transported over long distances. Although HBCD is not applied directly to agricultural soils, it can enter soil via a series of environmental routes and be adsorbed by soil organic matters. It could also pose a threat to human health via bioaccumulation through the food chain. Bioremediation has increasingly been applied as a soil remediation technique because it is low cost, easy to use, highly efficient, highly safe in the environment, and supports the goal of developing agricultural soil in a green manner. This study summarized and analyzed the process by which HBCD pollutes agricultural soil, including via its sources and environmental behaviors, and the bioremediation methods to mitigate it, aiming to provide a useful reference for the effective control of HBCD in agricultural soils and the green remediation of soil pollution. |
