Comparative Study of PM10 Concentrations and Their Elemental Composition Using Two Different Techniques during Winter–Spring Field Observation …
2022
The aims of this study were to determine the concentrations and elemental composition of PM10 in the village of Kotórz Mały (Poland), to analyse their seasonal variability, to determine the sources of pollutant emissions and to compare the consistency of the results obtained using different methods. Sampling and weather condition measurements were carried out in the winter (January–February) and spring (April) of 2019. Two combinations of different techniques were used to examine PM10 concentrations and their chemical composition: gravimetric method + atomic absorption spectrometry (GM+AAS) and continuous particle monitor + energy dispersive X-ray fluorescence (CPM+EDXRF).…
Understanding maritime transport route choice among Irish exporters: A latent class approach
2021
Abstract The reduction in the level of maritime connectivity between Ireland and mainland Europe has been the focus of concern for Irish exporters since the withdrawal of the United Kingdom from the European Union in January 2019. In a post-Brexit scenario, new proposals are being sought to address Ireland's reliance on the UK land-bridge. Policy developments aimed at circumventing the potential negative impact of UK customs checks for Irish exports include the proposals by the European Commission to introduce new direct shipping routes connecting main ports in Ireland with Zeebrugge and Antwerp in Belgium, as well as with Rotterdam in the Netherlands. From a transport policy perspective, f…
Développement de méthodes de référence pour les biomarqueurs du bilan lipidique : application au contrôle qualité en biologie clinique
2013
Reliable measurements in medical biology are essential for early screening and appropriate follow-up of patients. Ensuring metrological traceability of clinical measurements to higher order reference methods or certified reference materials enables to obtain comparable results over time and between different laboratories that could use different methods to quantify the same biomarker.In this study, reference methods were developed and validated for lipid profile biomarkers (total cholesterol, triglycerides, HDL-C, and LDL-C). Their value added in proficiency testing schemes was demonstrated against consensus mean. They were also used to characterize a certified reference material (CRM) that…
