AB  - Microplastic pollution has attracted mounting concerns worldwide. Microplastics 
      may concentrate organic and metallic contaminants; thus, affecting their 
      transport, fate and organismal exposure. To better understand organic 
      contaminant-microplastic interactions, our study explored the sorption of 
      selected polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers 
      (PBDEs), alpha-hexabromocyclododecane (alpha-HBCDD), and organophosphate flame retardants 
      (OPFRs) on high-density polyethylene (HDPE) and polyvinylchloride (PVC) 
      microplastics under saline conditions. Sorption isotherms determined varied 
      between chemicals and between HDPE and PVC microplastics. Log Freundlich sorption 
      coefficients (Log K(F)) for the targeted chemicals ranged from 2.01 to 
      5.27 L kg(-1) for HDPE, but were significantly lower for PVC, i.e., ranging from 
      Log K(F) data (2.84 - 8.58 L kg(-1)). Significant correlations between chemicals' 
      Log K(F) and Log K(ow) (octanol-water partition coefficient) indicate that 
      chemical-dependent sorption was largely influenced by their hydrophobicity. 
      Sorption was evaluated using three size classes (< 53, 53 - 300, and 300 - 
      1000 microm) of lab-fragmented microplastics. Particle size did not significantly 
      affect sorption isotherms, but influenced the time to reach equilibrium and the 
      predicted maximum sorption, likely related to microplastic surface areas. The 
      presence of biofilms on HDPE particles significantly enhanced contaminant 
      sorption capacity, indicating more complex sorption dynamics in the 
      chemical-biofilm-microplastic system. Our findings offer new insights into the 
      chemical-microplastic interactions in marine environment.
