The concentration and distribution patterns of parent and polar PAHs including oxygenated PAHs (oxyPAHs), nitrated PAHs (NPAHs) and heterocyclic PAHs (HPAHs) were determined in water, sediment and oysters from an ecologically and economically important estuary of New South Wales, Australia. Total concentrations of PAHs, oxyPAHs, NPAHs and HPAHs were higher in sediments compared to oyster tissue and water. For most polar PAHs, total concentrations for water, sediment and oyster samples were <1 μg/g (μg/l for water) while parent PAH concentrations were several orders of magnitude higher. Computed biota-sediment accumulation factors (BSAFs) on lipid-normalized oyster concentrations revealed that while ∑oxyPAHs and ∑HPAHs exhibited low accumulation from sediment to oyster tissues (BSAF <1), ∑PAHs and ∑NPAH were found to be accumulated at high levels (BSAF >1). BSAF individual computation showed that bioaccumulation of nine investigated HPAHs in oyster tissues were relatively low and only 2-EAQ (oxyPAH) and 1N-NAP (NPAH) showed high levels of accumulation in oyster tissues, similar to parent PAHs. To the best of our knowledge, this is the first known study on the bioavailability of polar and non-polar PAHs in an Australian aquatic environment. The outcome of this study might be a useful indicator of the potential risks of polar PAHs to humans and other living organisms.]]> Thu 24 Mar 2022 13:44:29 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:56122 Thu 01 Aug 2024 13:23:02 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38320 −1) and dissolved organic matter(0–20 mg L⁻¹). The string rate of more than 100 rpm indicated the DGT will not likely be affected by flow rate in the aquatic environment. The study successfully indicates the DGT’s performance on diuron, providing a promising technique for future investigation of distribution and occurrence in the natural environment.]]> Fri 27 Aug 2021 12:02:40 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40344 Fri 08 Jul 2022 14:12:45 AEST ]]>
