水成膜泡沫（afff）作为阻燃剂的使用是全氟和多氟烷基物质（PFASs）污染进入水生环境的一个关键的点源。本研究调查了加尔维斯顿湾地表水和生物群（贝类和鱼类）中的全氟磺酸污染，此前afff用于扑灭鹿园（德克萨斯州休斯顿）国际码头公司（ITC）储油罐的石化火灾（2019年3月17日至20日）。2019年3月至11月，在地表水和生物群中测量了多达12种EPA优先的全氟辛烷磺酸的水平。地表水中PFASs的水平显示，2019年3月和4月的平均总水平比随后几个月的测量值高出4倍至300倍。PFOS（全氟辛烷磺酸）是最丰富的同源物，≥66%的全氟辛烷磺酸。2019年3月和4月，在3%的分析样本中，全氟辛烷磺酸的最高水平超过了德克萨斯州的水监管限值0.6 μg L - 1。全氟辛烷磺酸也是东部牡蛎（Crassostrea virginica）、红颡鱼（Sciaenops ocellatus）、红颡鱼（Bagremarinus）和斑点鲷（Cynoscion nebulosus）中最显著的同源物（占总全氟辛烷磺酸的66%）。分别于2019年4月和5月在牡蛎和斑点鲷鱼中测量到全氟辛烷磺酸身体负荷的统计学显著升高。对海产品安全的风险比计算表明，建议每周食用1-2餐的加夫托帆鲶鱼和红鼓鱼，每周食用2餐的斑点鱼对人体接触全氟辛烷磺酸具有保护作用。牡蛎中的含量表明，人类从饮食中接触到这种物质不会立即引起关注。我们的研究结果强调需要持续监测，以评估PFASs的长期命运和海产品建议。
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. PFASs levels in surface waters showed mean total levels in March and April 2019 to be from 4× to ~300× higher than those measured in the following months. PFOS (perfluorooctanesulfonic acid) was the most abundant homolog measured at ≥66% of total PFASs. Maximal PFOS levels exceeded the State of Texas' water regulatory limit of 0.6 μg L−1in 3% of the samples analyzed in March and April 2019. PFOS was also the most prominent homolog (≥66% of total PFASs) measured in eastern oysters (Crassostrea virginica), red drum (Sciaenops ocellatus), gafftopsail catfish (Bagremarinus), and spotted seatrout (Cynoscion nebulosus). A statistically significant elevation of PFOS body-burdens was measured in oysters and spotted seatrout in April and May 2019, respectively. A Hazard Ratio calculation for seafood safety suggests an advisory of 1–2 meals per week for gafftopsail catfish and red drum, and 2 meals per week for spotted seatrout to be protective for human exposure to PFOS. The levels in oysters indicated no immediate concerns for the dietary exposure of humans. Our results highlight a need for continual monitoring to assess the long-term fate and seafood advisories for PFASs.
