Building a European exposure science strategy
(Nature Publishing Group, 2019-12-02)Exposure information is a critical element in various regulatory and non-regulatory frameworks in Europe and elsewhere. Exposure science supports to ensure safe environments, reduce human health risks, and foster a sustainable ... -
Evaluation of hand-held XRF for screening waste articles for exceedances of limit values for brominated flame retardants
(Environmental Protection Agency, 2019-03)Recent research has demonstrated the presence of restricted persistent organic pollutant (POP) brominated flame retardants (BFRs) in items such as children s toys and food contact articles. As the presence of these ... -
Portable X-ray fluorescence for the detection of POP-BFRs in waste plastics
(Elsevier, 2018-05-26)The purpose of this study was to establish the efficacy of portable X-ray fluorescence (XRF) instrumentation as a screening tool for a variety of end of life plastics which may contain excess amounts of brominated flame ... -
Leaching of decabromodiphenyl ether and hexabromocyclododecane from fabrics under simulated landfill conditions
(KeAi Communications Co. Ltd, 2019-12-30)A series of laboratory experiments were conducted to examine the leaching of decabromodiphenyl ether (BDE-209) and hexabromocyclododecane (HBCDD) from a mix of three fabrics. Consistent with previous reports that such ... -
Phasing-out of legacy brominated flame retardants: The UNEP Stockholm Convention and other legislative action worldwide
(Elsevier, 2020-08-18)Due to their toxicity and persistence, several families of brominated flame retardants (BFRs) have been listed as persistent organic pollutants (POPs) in the Stockholm Convention, a multilateral treaty overseen by the ... -
Report No: 343: Elucidating levels and pathways of human exposure in Ireland to brominated flame retardants and perfluoroalkyl substances, ELEVATE project highlights video
(Environmental Protection Agency, 2020-09-25)Brominated flame retardants (BFRs) and perfluoroalkyl substances (PFASs) have been used extensively in applications such as electrical goods, soft furnishings and building insulation foam. The ELEVATE project generated ... -
Report No: 343: Elucidating levels and pathways of human exposure in Ireland to brominated flame retardants and perfluoroalkyl substances
(Environmental Protection Agency, 2020-09-25)Brominated flame retardants (BFRs) and perfluoroalkyl substances (PFASs) have found extensive use in consumer applications such as electrical and electronic goods, soft furnishings, and building insulation foam to impart ... -
Sensitive and selective quantification of glyphosate and aminomethylphosphonic acid (AMPA) in urine of the general population by gas chromatography-tandem mass spectrometry
(Elsevier, 2020-08-26)Glyphosate is the highest volume herbicide used worldwide, and its main biodegradation product is aminomethylphosphonic acid (AMPA), both are listed as priority substances in the Human Biomonitoring for Europe initiative ... -
Human biomonitoring of glyphosate exposures: State-of-the-art and future research challenges
(MDPI, 2020-08-18)Abstract: Glyphosate continues to attract controversial debate following the International Agency for Research on Cancer carcinogenicity classification in 2015. Despite its ubiquitous presence in our environment, there ... -
The EMEP Intensive Measurement Period campaign, 2008-2009: characterizing carbonaceous aerosol at nine rural sites in Europe
(European Geosciences Union (EGU), 2019-04-03)Carbonaceous aerosol (total carbon, TCp) was source apportioned at nine European rural background sites, as part of the European Measurement and Evaluation Programme (EMEP) Intensive Measurement Periods in fall 2008 and ... -
Summertime primary and secondary contributions to Southern Ocean cloud condensation nuclei
(Nature Research (part of Springer Nature), 2019-07-18)Atmospheric aerosols in clean remote oceanic regions contribute significantly to the global albedo through the formation of haze and cloud layers; however, the relative importance of ‘primary’ wind-produced sea-spray over ... -
Sea-spray regulates sulfate cloud droplet activation over oceans
(Nature Research (part of Springer Nature), 2020-04-08)Sulfate aerosols are typically the dominant source of cloud condensation nuclei (CCN) over remote oceans and their abundance is thought to be the dominating factor in determining oceanic cloud brightness. Their activation ... -
Concentrations of perfluoroalkyl substances in human milk from Ireland: Implications for adult and nursing infant exposure
(Elsevier, 2019-12-20)Concentrations of 10 perfluoroalkyl substances (PFASs) were measured in 16 pools of human milk from Ireland. Only four PFASs were detected (PFOA, PFNA, PFHxS and PFOS), with concentrations dominated by PFOA which was ... -
VERITAS detection of LS 5039 and HESS J1825-137
(Elsevier, 2019-11-07)With 8 h of observations, VERITAS confirms the detection of two very high energy gamma-ray sources. The gamma-ray binary LS 5039 is detected with a statistical significance of 8.8σ. The measured flux above 1 TeV is near ... -
Ultra-sensitive label free imaging below the resolution limit
(SPIE (Society of Photo-optical Instrumentation Engineers) Digital Library, 2019-02-02)Almost all known nanoscopy methods rely upon the contrast created by fluorescent labels attached to the object of interest. This causes limitations on their applicability to in vivo imaging. A new label-free spectral ... -
Experimental assessment of clinical MRI-induced global SAR distributions in head phantoms
(Elsevier, 2019-10-05)Accurate estimation of SAR is critical to safeguarding vulnerable patients who require an MRI procedure. The increased static field strength and RF duty cycle capabilities in modern MRI scanners mean that systems can easily ... -
