AB  - While numerous studies have demonstrated the environmental behavior of legacy 
      persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs) 
      and organochlorine pesticides (OCPs), information regarding sorption and 
      bioaccumulation potential of other widely used organic chemicals such as 
      halogenated flame retardants (HFRs) is limited. This study involved a 
      comprehensive field investigation of multi-class hydrophobic organic contaminants 
      (HOCs) in environmental media and fish in Singapore Strait, an important tropical 
      maritime strait in Southeast Asia. In total, 90 HOCs were analyzed, including 
      HFRs, synthetic musks, PCBs, OCPs, as well as triclosan and methyl triclosan. The 
      results show that the organic carbon normalized sediment-seawater distribution 
      ratios (C(SED)/C(WD)) of the studied compounds are comparable to the organic 
      carbon-water partition coefficients (K(OC)), over a log K(OC) range of 
      approximately 4-11. The observed species-specific bioaccumulation factors (BAFs), 
      biota-sediment accumulation factors (BSAFs), organism-environment media fugacity 
      ratios (f(FISH)/f(WD) and f(FISH)/f(SED)) and trophic magnification factors 
      (TMFs) indicate that legacy POPs and PBDE 47 show bioaccumulation behavior in 
      this tropical marine ecosystem, while triclosan, tonalide, 
      dodecachlorodimethanodibenzocyclooctane stereoisomers (DDC-COs), and 
      hexabromocyclododecanes (HBCDDs) do not. Methyl triclosan and galaxolide exhibit 
      moderate biomagnification. Tetrabromobisphenol A (TBBPA) and 1,2-bis 
      (2,4,6-tribromophenoxy)ethane (BTBPE) were detected in environmental media but 
      not in any of the organisms, suggesting low bioaccumulation potential of these 
      flame retardants. The apparently low bioaccumulation potential of the studied 
      HFRs and synthetic musks is likely because of metabolic transformation and/or 
      reduced bioavailability due to the hydrophobic nature of these compounds.
