Source apportionment and health risk assessment of polycyclic aromatic hydrocarbons (PAHs) in the coastal ecosystem of the Brunei Bay, Brunei
Pollution characteristics and associated ecological risks of PAHs in sediments from Brunei Bay, Brunei were investigated. The concentrations of ∑16 PAHs ranged from 826.7 to 2955.3 μg kg− 1 , indicating moderate to high level of pollution. Source apportionment of PAHs by molecular isomeric ratios...

| description | Pollution characteristics and associated ecological risks of PAHs in sediments from Brunei Bay, Brunei were
investigated. The concentrations of ∑16 PAHs ranged from 826.7 to 2955.3 μg kg− 1
, indicating moderate to high
level of pollution. Source apportionment of PAHs by molecular isomeric ratios and positive matrix factorization
model indicated impact of potential anthropogenic PAH sources including combustion of biomass and fossil
fuels. The data indicated relatively no significant ecotoxicological risk for most of PAH compounds. To estimate
the individual c-PAH toxicity, the toxic equivalent quantity (c-TEQ) was calculated. Results of the TEQ analysis
showed that BaP followed by DBA and BaA are the most carcinogenic of PAHs examined in the study area. The
evaluation of human health risk of PAHs revealed that the cancer risk of PAHs for adults and children was higher
than the USEPA threshold (<1E− 06) and lower than 1E-3, implying low to moderate risk. |
