Information on the occurrence of contaminants of emerging concern (CEC) in the aquatic ecosystems that North American indigenous communities depend on is scarce. Given the particular importance of these ecosystems for food and economic security of indigenous communities, assessing the presence of contaminants becomes very important. Therefore, we wanted to highlight an excellent study [1] […]

The PFAS on the regulatory radar, such as PFOS, PFOA, and other related targets on typical laboratory lists, are anionic, or neutral. Therefore, the methods are optimized for anionic PFAS and feature standardized solid extraction using methanol containing ammonia, and weak anion exchange cleanup. However, many aqueous film forming foam (AFFF) active ingredients can be […]

We in British Columbia love our Pacific wild salmon and view them as keystone species and indicators of ecosystem wellbeing. Numbers have dropped significantly recently from multiple stressors including climate change, habitat loss, pollution and more. With current and proposed pipelines that will carry diluted bitumen (dilbit) from the oil sands through spawning habitat and […]

The widespread use of aqueous film forming foams (AFFF) containing PFAS at airports all over the world has resulted in contamination of ground and surface water, and soil. In addition to the many ecosystem effects that are still being studied, how are microbial communities affected? Which PFAS are microbes able to degrade and how does […]

How many contaminants of emerging concern (CEC) can you assess from one set of mussels? Turns out if SGS AXYS is doing the measurement, it’s at least 330! Scientists Andrew James, Jennifer Lanksbury, Tarang Khangaonkar and James West from the University of Washington Tacoma, Washington Department of Fish and Wildlife, and Pacific Northwest National Laboratories […]
