“…14−17 In most of the surveys, the EDIs were estimated based on raw food materials and general food consumption data without considering the impact of cooking on dietary intake of PFASs, which could be misleading. 18 Some studies reported that the concentrations of short-chained PFASs decreased, while long-chained PFASs increased during cooking, such as frying, steaming, or boiling. 18,19 Recently, a 1 or 2 day duplicate diet was employed to assess EDI, which was proven to improve human exposure assessment.…”

The restriction on legacy perfluoroalkyl substances (PFASs) has led to increasing application and contamination of their precursors and novel alternatives. However, the indirect contribution from precursors has not been well characterized. In this study, 24 PFASs were measured in the paired human blood and urine from general volunteers (n = 20), as well as their corresponding exposure matrices (7 day duplicate diet, drinking water and dust). Perfluorooctanoic acid (PFOA) was predominant, followed by 6:2 chlorinated polyfluoroalkyl ether sulfonate (6:2 Cl-PFESA), contributing 21.6–47.0 and 6.6–20.0% of the total concentrations, respectively. Total oxidable precursor (TOP) assay and isomeric analysis coupled with a toxicokinetic model suggested that around 19% of perfluorooctane sulfonate (PFOS) in human was contributed by its precursors. The strong correlation between the estimated daily intake (EDI) and human blood concentration for 6:2 Cl-PFESA suggested that it was mainly contributed by direct exposure. The bioavailability of 6:2 Cl-PFESA in the food matrices was estimated as 18.6% by comparing the estimated and measured blood concentrations, implying that human exposure might be overestimated if the bioavailability of PFASs in food was not considered. Assuming that they had a similar bioavailability, it was estimated that ca. 20% of PFOS body burden was from indirect exposure to its precursors, which was supported by TOP assay.

Measurements of chemical persistence in natural environments can provide insight into behavior not easily replicated in laboratory studies. However, it is difficult to find environmental situations suitable for such measurements, particularly for substances with half-lives exceeding several weeks. The objective of this study was to demonstrate that a strategic postflood monitoring campaign can be used to quantify transformation halflives on the scale of months in a real aquatic system. Water samples were collected in the upper Brisbane River estuary on 36 occasions over 37 weeks and analyzed for 127 pharmaceuticals and personal care products (PPCPs), pesticides, and perfluoroalkyl substances (PFASs). High quality time trend data were obtained for 41 substances. For many of these, data on the input of a wastewater treatment plant to the upper estuary were also obtained. A mass balance model of the estuary stretch was formulated and parametrized using PFASs as persistent benchmarking chemicals. Transformation half-life estimates were obtained for 10 PPCPs and 7 pesticides ranging from 18 to 260 days. Furthermore, insight was obtained into dominant transformation processes as well as the magnitude of chemical inputs to the estuary and their sources. The approach developed shows that under certain conditions, estuaries can be used to quantify the persistence of organic contaminants with half-lives of the order of several months.

“…A variety of environmental chemicals such as metals, PAHs (Lusher, Hollman and Mandoza-Hill, 2017), phthalates (Heudorf,at al., 2007), PFAAS (Taylor et al, 2019) are known to accumulate on the surface of plastics over decades. The associated chemicals directly or indirectly access its way through the human system contributes to human health issues such as; the induction of acute in ammation in the liver due to associated metals (Revel, Châtel and Mouneyrac, 2018a), the impact of POPs to the lymphatic system (Heinrich and Braunbeck, 2019) and the leaching POPs that enhance gut infectivity or immunestimulatory properties of the biological agents adsorbed to their surface (Van Cauwenberghe and Janssen, 2014), and (Ravit et al, 2019).…”

The environmental, economic, and social impacts of micro and nano plastic (MNPs) pollution have caused significant global concern, which is exacerbated by the MNPs associated chemicals and biological entities that could directly or indirectly impact human health. The systematic review of research accomplished on this issue could enhance the understanding surrounding the toxicological risks of MP and its pathways to the human system. A significant amount of research is available on microplastic; still, the research executed to define the chemical impact and risk scenarios of microplastics on human health is limited. The objective of this study was to catalogue the literature on the toxicological impacts of MNPs on humans and the resulting biological consequences. A total of 95 publications were reviewed following the Cochrane protocol and screened based on the direct and indirect health impacts of MNPs to the human systems using the RevMan 5 software. Processing of collected data resulted in a total of 19 publications (until July 2021) that fulfilled the inclusion criteria and provided evidence of the potential impacts of MNPs, particularly in relation to the average sizes of Large MPs - 5mm - 1mm; MPs - 1mm - 0.1μm; NPs - 1-1000nm. Detailed analysis of data categorized into scenarios of chemical, toxicological, and biological impacts of MNPs on human health indicated that additives and associated contaminants of MNPs would pose a significant risk to human health. This is the first review that streamlines the notion that indirect impacts of MNPs caused due to MNP-associated chemicals are more severe than the direct impacts such as ingestion of MNPs.
