Article Synopsis
- PFAS are man-made contaminants found in wastewater, and their removal from drainage water is challenging due to varying effectiveness of current treatment methods like activated carbon and ion exchange resins.
- This study investigates using inexpensive pine and spruce bark, by-products of the forestry industry, as an alternative for filtering PFAS from contaminated water, with laboratory tests revealing pine bark to be more effective than spruce bark.
- Although overall PFAS removal was low (less than 20%), notable reductions of 40%-80% for PFOS were achieved, indicating that while these materials alone may not suffice for complete treatment, they could be beneficial in specific contexts or paired with other methods.

Article Synopsis
- - PFAS, commonly found in consumer products and industrial applications, accumulate at waste management facilities, prompting the need for effective monitoring methods.
- - A study in Sweden analyzed drainage water samples using both grab and composite sampling methods, revealing that grab samples consistently showed higher PFAS concentrations than composite samples.
- - The research indicated that while both sampling methods could effectively analyze target PFAS compounds, differences in extractable organofluorine levels suggested that grab sampling might provide more reliable data due to fluctuations in discharges.

Article Synopsis
- The study examined water samples from a waste management facility in Sweden to identify sources and concentrations of PFAS and extractable organofluorine (EOF).
- Ten PFAS compounds were found to represent a significant portion of the overall PFAS concentration, which varied between subsections of the facility.
- Oxidative conversion revealed that PFAS precursors contributed to increased EOF, while additional fluorinated compounds like tetrafluoroborate and hexafluorophosphate were linked to battery waste and played a major role in the EOF measurements.
