AB  - Microbial extracellular polymeric substances (EPS) and persistent organic 
      pollutants (POPs) commonly exist in the soil environment. Currently, there is a 
      knowledge gap regarding the effect of EPS on the fate of POPs in soil. In the 
      present study, 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) was used as a model 
      compound to investigate the effects of bovine serum albumin (BSA) and sodium 
      alginate (SA) - mimicking the main components of EPS - on sorption of POPs to 
      soils, through batch experiments. Irrespective of the concentration of BSA: the 
      addition of BSA did enhance the sorption capacity of BDE-47 to soils, due to 
      generation of more sorption sites. For SA, it increased the sorption capacity of 
      BDE-47 at low BDE-47 concentrations, while the presence of SA negatively affected 
      sorption of BDE-47 at high BDE-47 concentrations. The partition effect dominates 
      the sorption of BDE-47 to soils, but after adding either BSA or SA, the sorption 
      of BDE-47 to soils is dominated by surface sorption. Film diffusion and 
      intra-particle diffusion were also involved in the sorption process with and 
      without BSA or SA, with the latter being the rate-limiting step. The 
      heterogeneous surface and nonlinear sorption behavior of BDE-47 to soils 
      increased in the presence of either BSA or SA. The FTIR spectra indicated that 
      the aromatic CC, H-bonds and OH groups may be involved in the sorption process. 
      Therefore, BSA enhanced the retention of BDE-47 to soil, while SA's influence on 
      BDE-47 sorption to soil depended on the concentration of BDE-47.
