PFAS Contamination in Europe: Generating Knowledge and Mapping Known and Likely Contamination with “Expert-Reviewed” Journalism

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(15), P. 6616 - 6627

Published: April 3, 2024

While the extent of environmental contamination by per- and polyfluoroalkyl substances (PFAS) has mobilized considerable efforts around globe in recent years, publicly available data on PFAS Europe were very limited. In an unprecedented experiment "expert-reviewed journalism" involving 29 journalists seven scientific advisers, a cross-border collaborative project, "Forever Pollution Project" (FPP), drew both methods investigative journalism techniques such as open-source intelligence (OSINT) freedom information (FOI) requests to map across Europe, making public that previously had existed "unseen science". The FPP identified 22,934 known sites, including 20 manufacturing facilities, 21,426 "presumptive sites", 13,745 sites presumably contaminated with fluorinated aqueous film-forming foam (AFFF) discharge, 2911 industrial 4752 related PFAS-containing waste. Additionally, 231 "known users", new category for intermediate level evidence use considered likely be sources. However, true remains significantly underestimated due lack comprehensive geolocation, sampling, data. This model knowledge production dissemination offers lessons researchers, policymakers, about cross-field collaborations transparency.

ABSTRACT Food safety presents a global challenge, contributing to 600 million cases of foodborne diseases and 420,000 fatalities annually worldwide. In developing countries, such as Nepal, addressing food is particularly intricate arduous because the prevalent issues insecurity, poverty, illiteracy, regulatory hurdles. The objectives this comprehensive review are evaluate waterborne illnesses, examine existing regulations institutional frameworks, identify challenges associated with in Nepal. Additionally, aims propose strategies enhance measures country. An electronic search was conducted using relevant keywords include articles literature pertinent topic.

Multiclass Endocrine Disrupting Compounds in Surface Water from Selangor River Basin: Occurrence and Ecological Risk Assessment

ACS ES&T Water, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 13, 2025

Endocrine disrupting compounds (EDCs) are emerging environmental pollutants that cause detrimental effects on aquatic organisms and humans despite being present in the environment at trace level. There is insufficient detailed baseline data ecological risk assessments river basins globally, their ubiquity freshwater environments. Thus, this study investigated abundance, distribution, risks of EDCs surface water tropical basin, using combination solid phase extraction liquid chromatography-tandem mass spectrometry. Approximately, seven were detected, encompassing bisphenol A (BPA), S, F (BPF), perfluorooctanesulfonate, perfluorooctanoic acid, 17α-ethynylestradiol (EE2), 17β-estradiol (E2) Selangor River Basin. BPF was observed to be most prevalent compound 1098.40 ng/L followed by BPA (358.05 ng/L). Human activities, including industrial, commercial, residential waste discharge into tributaries lower streams, greatly influence prevalence EE2 E2 had significant (risk quotient > 1) may possess organisms. This addresses urgent need for EDC regulatory measures mitigation strategies protect ecosystems.

Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) in the Surface Waters of China: A Meta-Analysis

Water, Journal Year: 2025, Volume and Issue: 17(9), P. 1275 - 1275

Published: April 24, 2025

Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are recognized as persistent emerging pollutants worldwide, long-term exposure will seriously harm natural ecosystems human health. However, the largest producer consumer of fluorochemicals, China has limited research on environmental fate influencing factors PFOA PFOS in surface waters. To address this gap, a meta-analysis was conducted using 34 articles related to PFAS pollution China’s waters, published between 2000 2023, selected from PubMed Web Science databases. Existing investigations indicate that average concentrations water industrial areas southeast 1615.17 ng/L 8.41 ng/L, respectively, with wastewater being primary source. Meanwhile, analysis revealed positively correlated pH but negatively dissolved oxygen, total organic carbon sediment, salinity. Additionally, monitoring data show PFOA/PFOS levels European countries have declined since 2015, which is attributed restrictive measures usage PFAS. In conclusion, study provides scientific basis for developing control management strategies China.

Comprehensive Review of Global Perspectives on Per- and Polyfluoroalkyl Compounds: Occurrence, Fate, and Remediation in Groundwater Systems

Water, Journal Year: 2024, Volume and Issue: 16(11), P. 1583 - 1583

Published: May 31, 2024

Groundwater contamination with per- and polyfluoroalkyl compounds (PFASs) has become a growing worldwide environmental issue. The current review comprehensively evaluates the global perspective of PFAS pollution in groundwater. Data from 224 recent research articles covering various land use source types were reviewed, including industrial facilities, landfills, biosolids applications, firefighting training sites. bibliographic analysis shows an exponential increase publications on groundwater last five years, more than 50% coming USA, followed by Australia, Canada, China, Sweden. provides insight into analytical techniques, absorbing materials, treatment strategies, field tests, enhanced natural attenuation. Nevertheless, identified significant gaps areas precursor characterization, subsurface behavior, model validation data, long-term sustainable solutions. Moreover, cross-disciplinary approach is required to reduce regulate PFASs’ risks humans ecological system. This presents case study PFASs Saudi Arabian groundwater, revealing elevated levels PFOA PFOS highlighting need for region-specific studies remediation strategies. results will guide efforts protect drinking water supplies life-threatening contaminants.
