“…The coatings can be technical blends or polymers, and are often mixtures of homologue series of oligomers and polymers, as described in Chapter 3 on legislation. Each mixture typically contains from 3-20 structurally different molecules (Trier et al 2011a, Trier 2011, Kissa 2001) resulting in easily more than 100 different polyfluorinated compounds. At present, only a few technical blends and polymers have had their composition elucidated (Begley et al 2005, Trier et al 2011a, Trier 2011, Gebbink, 2013Dimzon 2014).…”

“…The applications particularly target fatty foods intended to be heated in the packaging or stored for an extended period (Trier 2011). Examples include fast food paper, microwave popcorn bags, cake forms, sandwich and butter paper, chocolate paper, paper for dry foods and pet foods (Kissa, 2001, Begley et al 2005Tittlemier et al 2007;Trier et al 2011a). It is estimated that approximately 17% of foods are packaged in paper and board (RingmanBeck 2010).…”

“…Studies that characterise the concentrations and release of PFASs from the consumer products are meager. [27,28] The consumer articles are generally treated with the precursor compounds, some of which are dialkylated and polymeric, and contain multiple functional groups. Such complex PFASs, which contain perfluorinated chains, can be precursors of monoalkylated perfluorinated compounds.…”

“…Commercial fluorochemicals are sold as industrial blends, which apart from the mixtures of PFASs, contain impurities. [28] Future environmental monitoring studies should include PFAS precursor compounds (e.g. fluorinated olefins, iodides and acrylates).…”

Environmental contextPerfluoroalkyl substances were recognised as global environmental pollutants 10 years ago. Although considerable advancements have been made in our understanding of the environmental distribution, fate and toxicity of perfluoroalkyl substances, several important issues remain to be resolved. This article identifies existing knowledge gaps that deserve further investigations to enable meaningful regulatory decisions. AbstractIt has been over a decade since perfluoroalkyl substances (PFASs) were discovered as global environmental contaminants. Considerable progress has been made in our understanding of the environmental fate and toxic effects of PFASs since then. Government regulations and voluntary emission reduction initiatives by industry have been effective in reducing environmental and human exposure to a major PFAS, perfluorooctane sulfonate (PFOS), in the United States and several other western countries. Although significant advances have been made in our understanding of the environmental chemistry of PFASs, considerable knowledge gaps still exist in several areas of environmental fate and risk assessments. Owing to their complex chemistry, involving existence of multiple precursors with significant numbers of structural isomers and mixtures of homologues, multiple degradation pathways and unique physicochemical properties, challenges remain in elucidating sources and environmental fate. In this overview, some of the knowledge gaps in PFASs’ research have been identified and suggestions for future research have been made.

Importance Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are ubiquitous synthetic chemicals that are suspected endocrine disruptors. Objectives To determine the extent to which PFASs are associated with increases in weight and body size and evaluate whether a lifestyle intervention modifies this association. Design, Setting, and Participants This prospective cohort study included 957 individuals who participated in the Diabetes Prevention Program trial, conducted from July 1996 to May 2001, and the Diabetes Prevention Program Outcomes Study, conducted from September 2002 to January 2014. Statistical analysis was conducted from September 1, 2017, to May 25, 2018. Interventions and Exposures The initial lifestyle intervention consisted of training in diet, physical activity, and behavior modification, with the major goals of achieving 7% weight loss with subsequent maintenance and a minimum of 150 minutes per week of physical activity. Participants randomized to placebo received standard information about diet and exercise. A total of 6 plasma PFASs were quantified at baseline and 2 years after randomization, means were calculated from baseline and year 2 concentrations, and means were summed to assess total PFAS burden. Main Outcomes and Measures Weight, waist circumference, and hip girth were measured at baseline and at scheduled visits. Results Of the 957 participants, 625 (65.3%) were women and 731 participants (76.4%) were between 40 and 64 years of age; 481 participants were randomized to the lifestyle intervention and 476 participants were randomized to the placebo arm. The PFAS concentrations were not different by treatment arm and were similar to concentrations reported for the US population in 1999-2000. The association of PFAS and weight change differed by treatment. Each doubling in total PFAS concentration was associated with an increase of 1.80 kg (95% CI, 0.43-3.17 kg; P = .01) from baseline to 9 years after randomization for the placebo group but not the lifestyle intervention group (−0.59 kg; 95% CI, –1.80 to 0.62 kg; P = .34). Similarly, each doubling in PFAS was associated with a 1.03-cm increase in hip girth in the Diabetes Prevention Program trial for the placebo group (95% CI, 0.18-1.88 cm; P = .02) but not the lifestyle intervention group (−0.09 cm; 95% CI, −0.82 to 0.63 cm; P = .80). No associations were observed for changes in mean waist circumference. Conclusions and Relevance Among adults at high risk for diabetes, higher plasma PFAS concentration was associated with increases in weight and hip girth over time, but a lifestyle intervention attenuated these associations. Diet and exercise may mitigate the obesogenic effects of environmental chemicals. Trial Registration ...
