Abstract
Hexabromocyclododecane (HBCD) was widely used as one of the brominated flame retardants (BFRs), which were routinely added to various consumer products; however, it has been listed as a persistent organic pollutant (POP) due to its potential toxicity, persistence in the environment and high bioaccumulation characteristics. In this study, the effect of fungal treatment to eliminate HBCD has been evaluated. Three strains of fungi (Ganoderma lucidum strain H, G. lucidum strain PT, and Antrodia cinnamomea) were examined for their HBCD removal abilities. The sorption of HBCD by the three different fungi was first evaluated in batch experiments. Our result shows all the three strains were able to eliminate approximately 80% of HBCD from aqueous solutions after 1 day. However, no bromide ions were measured at the end of the removal reactions. Furthermore, the autoclaved mycelia (SG1-H, SG1-PT, and SAC) show a 75% HBCD elimination, indicating that the fungal species showed most of the removal by sorption. These findings provide useful information to design feasible methods for bioremediation of HBCD. ? 2021 Chinese Agricultural Chemical Society. All rights reserved.
