Detecting high contributions of primary organic matter to marine aerosol: a case study
Ovadnevaite, Jurgita; O'Dowd, Colin; Dall'Osto, Manuel; Ceburnis, Darius; Worsnop, Douglas R.; Berresheim, Harald (Wiley-Blackwell, 2011-01-01)Using on-line High-Resolution Aerosol Mass Spectrometry, we report submicron organic marine aerosol plume concentrations peaking at 3.8 mu g m(-3). These concentrations are far greater than previously determined by off-line ... -
Eddy correlation measurements of ozone fluxes over coastal waters west of ireland
McVeigh, Philip; O'Dowd, Colin; Berresheim, Harald (Hindawi Limited, 2010-01-01)Measurements of ozone fluxes using the eddy-correlation (EC) technique were carried out for the first time at the Mace Head atmospheric research station, on the west coast of Ireland between August-October 2009. Vertical ... -
Evaluation of hand-held XRF for screening waste articles for exceedances of limit values for brominated flame retardants
Harrad, Stuart; Drage, Daniel; Abdallah, Mohamed; Sharkey, Martin; Berresheim, Harald (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 ... -
Halogenated flame retardants in Irish waste polymers: Concentrations, Legislative compliance, and preliminary assessment of temporal trends
Drage, Daniel; Sharkey, Martin; Al-Omran, Layla Salih; Stubbings, William A.; Berresheim, Harald; Coggins, Marie; Rosa, André Henrique; Harrad, Stuart (Elsevier, 2022-07-20)Halogenated flame retardants (HFRs) were measured in 470 waste plastic articles from Ireland between 2019 and 2020. We identified articles containing concentrations of polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane ... -
Leaching of decabromodiphenyl ether and hexabromocyclododecane from fabrics under simulated landfill conditions
Harrad, Stuart; Drage, Daniel S.; Sharkey, Martin; Berresheim, Harald (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 ... -
On the effect of wind speed on submicron sea salt mass concentrations and source fluxes
Ovadnevaite, Jurgita; Ceburnis, Darius; Canagaratna, Manjula; Berresheim, Harald; Bialek, Jakub; Martucci, Giovanni; Worsnop, Douglas R.; O'Dowd, Colin (Wiley-Blackwell, 2012-08-16)A High Resolution Time of Flight Aerosol Mass Spectrometer (HR-ToF-AMS) was evaluated for its ability to quantify submicron sea salt mass concentrations. The evaluation included both laboratory and field studies. Quantification ... -
Phasing-out of legacy brominated flame retardants: The UNEP Stockholm Convention and other legislative action worldwide
Sharkey, Martin; Harrad, Stuart; Abou-Elwafa Abdallah, Mohamed; Drage, Daniel S.; Berresheim, Harald (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 ... -
Portable X-ray fluorescence for the detection of POP-BFRs in waste plastics
Sharkey, Martin; Abdallah, Mohamed Abou-Elwafa; Drage, Daniel S; Harrad, Stuart; Berresheim, Harald (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 ... -
Primary marine organic aerosol: a dichotomy of low hygroscopicity and high ccn activity
Ovadnevaite, Jurgita; Ceburnis, Darius; Martucci, Giovanni; Bialek, Jakub; Monahan, Ciaran; Rinaldi, Matteo; Facchini, Maria Cristina; Berresheim, Harald; Worsnop, Douglas R.; O'Dowd, Colin (Wiley-Blackwell, 2011-11-01)High-time resolution measurements of primary marine organic sea-spray physico-chemical properties reveal an apparent dichotomous behavior in terms of water uptake: specifically sea-spray aerosol enriched in organic matter ... -
Sources, concentrations, and screening of hazardous brominated flame retardants from waste streams in Ireland
Sharkey, Martin James (NUI Galway, 2019-04-12)Brominated flame retardants (BFRs) are organohalogen compounds which are applied to polymer-based materials in order to meet fire safety standards. Some of the most commonly-used of these BFRs in consumer plastic over the ... -
Submicron ne atlantic marine aerosol chemical composition and abundance: seasonal trends and air mass categorization
Ovadnevaite, Jurgita; Ceburnis, Darius; Leinert, Stephan; Dall'Osto, Manuel; Canagaratna, Manjula; O'Doherty, Simon; Berresheim, Harald; O'Dowd, Colin (Wiley-Blackwell, 2014-10-18)Three years of continuous Aerosol Mass Spectrometry measurements at the Mace Head Global Atmosphere Watch research station revealed seasonal patterns in the chemical composition of submicron NE Atlantic marine aerosol as ... -
