Sorption in soils and bioaccumulation potential of 2,2′-DiBBPA
2,2′-Dibromobisphenol A (2,2′-DiBBPA) is frequently detected in the environment. However, the mobility of 2,2′-DiBBPA in the soil environment is poorly understood. The present study examined the effects of soil components such as the NaClO-resistant fraction, dithionite-citrate-bicarbonate -deminera...

| description | 2,2′-Dibromobisphenol A (2,2′-DiBBPA) is frequently detected in the environment. However, the mobility of 2,2′-DiBBPA in the soil environment is poorly understood. The present study examined the effects of soil components such as the NaClO-resistant fraction, dithionite-citrate-bicarbonate -demineralized fraction, humin fraction, black carbon, DOC-removed fraction, exogenous dissolved organic carbon and heavy metal cations on the adsorption of 2,2′-DiBBPA on several types of agricultural soils. The adsorption isotherms on soils and soil components were well fitted to the linear isotherm equation. 2,2′-DiBBPA sorption onto soils was dominated by soil organic matter content (SOM) and affected by exogenous dissolved organic carbon. Linear regression relationships between adsorption capacity (Kd) and soil characteristics were evaluated to predict partitioning of 2,2′-DiBBPA. Black carbon played a predominant role in the adsorption of 2,2′-DiBBPA. Heavy metal ions significantly inhibited the adsorptive behavior of 2,2′-DiBBPA under alkaline conditions. Semiempirical linear relationships were observed between biota-sediment accumulation factors (1.18–2.47)/logarithm of bioconcentration factors (BCFs, 2.49–2.52) of 2,2′-DiBBPA in lugworms and Kd. These results allow for the prediction of the bioaccumulation of 2,2′-DiBBPA in other soils. Furthermore, values of log BCF > 1.0 indicate the preferential bioaccumulation of 2,2′-DiBBPA in biota. These data are of significance for understanding the migration of 2,2′-DiBBPA in agricultural soils and bioaccumulation in organisms. |
