    In both muscle and liver samples, the highest level of PFAS chemical was PFOS, at 82.6 parts per billion (ppb) in a muscle sample and 2,970 ppb in a liver sample. [ 112 ] [ 113 ] 14 September 2021 EPA announced plans to revise effluent guidelines for businesses that conduct chromium electroplating operations and discharge PFAS in their wastewater.

    A new EU drinking water directive issued in 2020 adopted PFAS limit values. The limit values are 0.1 μg/L for the sum of 20 PFASs including PFHxS, and 0.5 μg/L for the sum of all PFASs. This directive is binding for all EU member nations. It is a minimum directive, and member states can elect to adopt stricter regulations. [19]

  9. Passive sampling - Wikipedia

    en.wikipedia.org/wiki/Passive_sampling

    The underlying principle of passive sampling is the flow of contaminant molecules or ions from the sampling medium (air or water) onto a collecting medium (the passive sampler), due to Fick's first law of diffusion and, depending on the passive sampler, a greater binding affinity of contaminants with the collecting medium as compared to the sampling medium.
