“…To date, only two studies, which were conducted at heavily polluted sites, have reported higher PFOS concentrations in fish flesh and liver than the values in this study (Lin et al, 2014;Naile et al, 2010). Taylor et al (2018) observed strong relationships between the proximity of the capture of fish to heavily contaminated areas. Taylor et al (2018) also suggested that this relationship can be affected by the movement patterns of the fish and the hydrology of the estuary that the fish were within.…”

Taylor et al (2018) also suggested that this relationship can be affected by the movement patterns of the fish and the hydrology of the estuary that the fish were within. Taylor (2018) recently surveyed the occurrence of PFOS in flesh tissue of four fresh water species (i.e.…”

“…In addition, the mean PFOS concentrations the flesh of these two species are only marginally above the trigger value. Unlike the previous studies by Taylor and co-workers (Taylor, 2018;Taylor et al, 2018), the fish in this study have been contained within the reservoir, thus, providing the conditions for high levels of accumulation of PFOS. Our research appears to be first published estimates of PFOS concentrations in fish exposed to treated effluent within Australia.…”

“…<10 ng/L). All previous studies examined the occurrence of PFOS in natural waters where there can potentially be movement of fish (Taylor et al, 2018). In other words, fish individuals might not be continuously exposed to PFOS in their habitat for their entire life.…”

This study examined the occurrence of 49 micropollutants in reclaimed water and Silver Perch (Bidyanus bidyanus) living in a reclaimed water reservoir. The numbers of micropollutants detected in reclaimed water, Silver Perch liver, and Silver Perch flesh were 20, 23, and 19, respectively. Concentrations of all micropollutants in reclaimed water, except benzotriazole, were well below the Australian Guideline for Recycled Water (AGRW) values for potable purposes. The concentration of benzotriazole in reclaimed water was 675 ± 130 ng/L while the AGRW value for this compound was 7 ng/L. Not all micropollutants detected in the water phase were identified in the Silver Perch flesh and liver tissues. Likewise, not all micropollutants detected in the Silver Perch flesh and liver were identified in the reclaimed water. In general, micropollutant concentrations in the liver were higher than in the flesh. Perfluorooctane sulfonate (PFOS) was detected at a trace level in reclaimed water well below the AGRW guideline value for potable purposes, but showed a high and medium bioconcentration factor in Silver Perch liver and flesh, respectively. In addition, the risk quotient for PFOS was medium and high when considering its concentration in Silver Perch liver and flesh, respectively. Results reported here highlight the need to evaluate multiple parameters for a comprehensive risk assessment. The results also single out PFOS as a notable contaminant of concern for further investigation.

“…When released into the aquatic environment, long-chain PFAS are bioaccumulative in biota (Bhavsar et al 2016 ;Taylor et al 2018 ), although the potential for bioaccumulation is variable or unknown among PFAS of different chain lengths and production age. The rate of bioaccumulation is variable between species and water body types (e.g., lotic, lentic, or saltwater).…”

1999). Importantly, oyster reefs have been found to have more diverse estuarine fish assemblages than sand habitat; for example, the large-scale subtidal oyster reefs in Pamlico Sound in North Carolina, USA, found more fish on oyster reefs than unstructured bottom habitat (Pierson & Eggleston, 2014). There has been increasing recognition of the importance of native oyster reefs in estuarine systems, but they have been declining globally (
