Article Synopsis
- PFOS is a common pollutant that poses various toxic risks to marine life, especially in urban and industrial coastal areas.
- This study examined the relationship between PFOS exposure and levels of l-carnitine and fatty acids in fish and dolphins from Galveston Bay and the northern Gulf of Mexico, finding higher PFOS levels in these organisms.
- Results indicated that l-carnitine is a more effective biomarker for PFOS exposure than fatty acids, as significant correlations between PFOS levels and carnitine were observed, which could indicate possible health issues like dyslipidemia.
The use of aqueous film forming foams (AFFFs) as fire retardants is an critical point-source for per- and polyfluoroalkyl substances (PFASs) pollution into the aquatic environment. This study investigated PFASs pollution in the surface waters and biota (shellfish and fish) of Galveston Bay, following AFFFs use to extinguish a petrochemical fire (March 17th to 20th, 2019) of oil storage tanks at the International Terminals Company (ITC) in Deer Park (Houston, TX). The levels of up to twelve EPA priority PFASs were measured in surface waters and biota from March-November 2019.
