We investigated temporal trends of blood serum levels 13 perfluorinated alkyl acids (PFAAs) and perfluorooctane sulfonamide (FOSA) in primiparous women (N = 413) from Uppsala County, Sweden, sampled 3 weeks after delivery 1996-2010. Levels the short-chain perfluorobutane sulfonate (PFBS) perfluorohexane (PFHxS) increased 11%/y 8.3%/y, respectively, long-chain perfluorononanoate (PFNA) perfluorodecanoate (PFDA) 4.3%/y 3.8%/y, respectively. Concomitantly, FOSA (22%/y), (PFOS, 8.4%/y),...
The discharge of persistent and mobile organic chemicals (PMOCs) into the aquatic environment is a threat to quality our water resources. PMOCs are highly polar (mobile in water) can pass through wastewater treatment plants, subsurface environments potentially also drinking processes. While few such compounds known, we infer that their number actually much larger. This Feature highlights issue from an environmental perspective assesses gaps appear exist terms analysis, monitoring,...
Air samples were collected from 4 field sites in Europe: 2 the UK, Hazelrigg (semi-rural) and Manchester (urban); 1 site Ireland: Mace Head (rural); Norway: Kjeller (rural). Additionally, air taken indoor locations Tromsø, Norway. using high-volume samplers employing sampling modules containing glass-fibre filters (GFFs, particle phase), glass columns with a polyurethane foam (PUF)-XAD-2-PUF sandwich (gaseous phase). Typical outdoor volumes required for determination of per- polyfluorinated...
The discharge of C6−C9 perfluorinated carboxylates (PFCAs) from major European rivers was studied and employed to assess emissions these compounds. Water samples were collected close the mouths 14 including Rhine, Danube, Elbe, Oder, Seine, Loire, Po. PFCA concentrations determined using LC-MS/MS used together with mean annual water flow estimate riverine PFCAs. highest concentration measured 200 ng/L for perfluorooctanoate (PFOA) in Po River. accounted two-thirds total PFOA all studied,...
Recent environmental surveys have ascertained the widespread occurrence of perfluorinated alkyl substances (PFAS) in tissues wildlife from Arctic. In present study, we investigated distribution a suite PFAS plasma, liver, brain, and egg samples adult glaucous gulls (Larus hyperboreus), an apex scavenger-predator seabird breeding Norwegian Perfluorooctane sulfonate (PFOS) was predominant all at concentrations that are highest reported thus far any arctic species populations. Among body...
Chlorinated paraffins (CPs) are high production volume chemicals, but data about their environmental fate scarce. CP mixtures composed of thousands isomers represent a major challenge for quantification at low levels in samples. Here, we present novel analytical method analysis short-chain, medium-chain, and long-chain CPs single injection, that also yields information congener group pattern. Our detection is based on direct injection into an atmospheric pressure chemical ionization source...
Contributions of direct and indirect (via precursors) pathways human exposure to perfluorooctane sulfonic acid (PFOS) isomers perfluoroalkyl carboxylic acids (PFCAs) are estimated using a Scenario-Based Risk Assessment (SceBRA) modelling approach. Monitoring data published since 2008 (including samples from 2007) used. The daily exposures (resulting both precursor intake) for the general adult population highest PFOS perfluorooctanoic (PFOA), followed by perfluorohexanoic (PFHxA)...
Summary: Per- and polyfluoroalkyl substances (PFASs) are man-made chemicals that contain at least one perfluoroalkyl moiety, –CnF2n–. To date, over 4,000 unique PFASs have been used in technical applications consumer products, some of them detected globally human wildlife biomonitoring studies. Because their extraordinary persistence, environmental exposure to will be a long-term source concern. Some such as perfluorooctanoic acid (PFOA) perfluorooctanesulfonic (PFOS) investigated...
The acid dissociation constants (pKas) of perfluoroalkyl carboxylic acids (PFCAs) have been the subject discussion in literature; for example, values from −0.2 to 3.8 suggested perfluorooctanoic (PFOA). dissociated anionic conjugate bases PFCAs negligible air–water partition coefficients (KAWs) and do not volatilize water. neutral acids, however, relatively high KAWs volatilization water has demonstrated. extent environment will depend on pH their pKa. Knowledge pKas is therefore vital...
REACH registered neutral, ionizable and ionic organic chemicals were evaluated for their potential to present a hazard drinking water sources.
We analysed floor dust samples from 65 children's bedrooms in Finland collected 2014/2015 for 62 different per- and polyfluoroalkyl substances (PFASs) with a simple highly efficient method. Validation results the analysis of standard reference material (SRM) 2585 were good agreement literature data, while 24 PFASs quantified first time. In bedrooms, five perfluoroalkyl carboxylic acids (PFCAs) perfluorooctane sulfonic acid (PFOS) detected more than half highest median concentration 5.26 ng/g...
