“…For PFHpA, PFNA, PFDA and PFUnA, a significant change point (in 2004 in all cases) was determined by the independent change point analysis in a compacted snow ("firn") core (dated: 1997-2007) from the Italian Alps (Additional file 7, Figures S14, S22, S27, S32) [104]. For PFHpA no significant change was observed before the change point and a significant decrease was observed after the change point.…”

Background: There is a concern that continued emissions of man-made per-and polyfluoroalkyl substances (PFASs) may cause environmental and human health effects. Now widespread in human populations and in the environment, several PFASs are also present in remote regions of the world, but the environmental transport and fate of PFASs are not well understood. Phasing out the manufacture of some types of PFASs started in 2000 and further regulatory and voluntary actions have followed. The objective of this review is to understand the effects of these actions on global scale PFAS concentrations.Methods: Searches for primary research studies reporting on temporal variations of PFAS concentrations were performed in bibliographic databases, on the internet, through stakeholder contacts and in review bibliographies. No time, document type, language or geographical constraints were applied in the searches. Relevant subjects included human and environmental samples. Two authors screened all retrieved articles. Dual screening of 10% of the articles was performed at title/abstract and full-text levels by all authors. Kappa tests were used to test consistency. Relevant articles were critically appraised by four reviewers, with double checking of 20% of the articles by a second reviewer. Meta-analysis of included temporal trends was considered but judged to not be appropriate. The trends were therefore discussed in a narrative synthesis.

“…Semi-volatile organic pollutants are normally transported via the atmosphere to the Alpine area. [26][27][28] However, there are no studies investigating the occurrences and temporal trends of FTOHs in the Alpine atmosphere, which restricts our comprehensive understanding of their risks to human and environmental health. In particular, PFCAs have been detected in Alpine lake sediment.…”

Environmental context. The transport and fate of organic pollutants such as fluorotelomer alcohols (FTOHs) in the atmosphere affect their risks to the environment and human health. On the basis of hourly trajectory predictions, we found that, from 2007 to 2010, individual levels of 6:2, 8:2 and 10:2 FTOH were from nondetectable to 72.4 pg m À3 at two Alpine summits. Air mass origin was an important factor determining the Alpine atmospheric FTOH levels.Abstract. The transport and fate of fluorotelomer alcohols (FTOHs) in the atmosphere affect their risks to the environment and human health. In this study, we aimed to investigate the sources, transport and temporal variations of FTOHs (6:2, 8:2 and 10:2 FTOH) at two Alpine summits (Sonnblick and Zugspitze). The active air sampler consisting of four XAD cartridges was applied to collect FTOHs from 2007 to 2010. Four separate cartridges were assigned for four air flow regimes (three European sectors and one mixed source origin), and switched and controlled on the basis of an hourly trajectory prediction. FTOH (6:2, 8:2 and 10:2) was measured with individual concentrations ranging from less than the limit of detection to 72.4 pg m À3 . Also, 8:2 FTOH was the dominant compound, accounting for 41-72 % of the total FTOH (SFTOH) concentration. Significant differences were not observed in FTOH concentrations between Sonnblick and Zugspitze since the two sites are relatively close compared with the geographic extent of the area studied. Air-flow regime was an important factor determining the atmospheric FTOH levels. Particularly at Zugspitze, air mass from the NE (regions north-east of the Alps) showed the highest median SFTOH concentration (36.9 pg m À3 ), followed by S (the Po basin in Italy), NW (regions north-west of Alps) and M (mixed source origin, polar regions or high altitudes). Furthermore, the seasonal variation in FTOH concentrations was not correlated with the site temperatures, but was dependent on the wind speed. Overall, the results indicated low FTOH concentrations at these two Alpine summits compared with European populated cities and provided important information for understanding the fate of FTOHs in the Alpine atmosphere.

“…PBDEs can be atmospherically transported over long distances and even to high mountain regions. PBDEs can also leak to local water intakes, threatening the areas at some distance from the source of pollution [21].…”

“…1 correspond to the maximal determined concentrations. Apart from waters in lakes and rivers, results are given that were determined in firn core from Colle Gnifetti in the Monte Rosa Massif in the Swiss-Italian Alps [21]. The maximal concentration levels registered over the years 1996-2008 do not exceed several ng/L, though they are not lower than in rivers.…”
