In May 2021, Quasimeme held a survey amongst the participants, suggestions for new exercises were made. Quasimeme used these suggestions to conduct a survey among the respondents. As a result Quasimeme is starting a development exercise specifically for measurements of PFASs in (sea)water.
Poly- and perfluoroalkyl substances, or PFASs are a group of chemical substances that are man-made and do not occur naturally in the environment. PFAS is present in many products because of their useful properties: they can make liquids flow well (which make them suitable for extinguishing foam) and are water, grease, dirt and dust repellent (ideal for use in all-weather clothing, baking paper and non-stick pans). However, there are PFAS of concern as some PFASs may cause health risks with long-term exposure. Additionally, PFAS are very stable substances and remain in the environment. In recent years, PFAS in global environmental research has an increased interest making proficiency tests needed.
Initially, this exercise will concern seawater and estuarine water, but if there is more interest, Quasimeme can involve other types of water too. Quasimeme invites everyone interested in this exercise to get in touch with us via email and to join our discussion platform on LinkedIn.
