Towards the generation of synthetic ambient aerosols for instrument calibration and health studies (EMPIR AEROMET & EMPIR AeroTox) 06/02/2020 Konstantina Vasilatou of project partner METAS recently gave a dual EMPIR project presentation at the TC-Metrology in Chemistry (TC-MC) Annual Meeting, 5 February 2020 at METAS, Bern, Switzerland. As well as the AEROMET project, “Towards the generation of synthetic ambient aerosols for instrument calibration and health studies (EMPIR AEROMET & EMPIR AeroTox)” also illustrated work under the AeroTox project. The overall aim of the AeroTox project is to identify correlations between particle component/properties (metrics) with adverse outcome pathways that are associated with the induction of acute and chronic health effects within the European population. This will be delivered through the development of a new method for studying in vitro cytotoxicity based on the use of ‘tailored’ synthetic ambient aerosols combined with high-resolution optical imaging and state-of-the-art cell analysis methods. The Technical Committee of Metrology in Chemistry (TC-MC) is a Joint EURAMET-Eurachem Technical Committee. It is concerned with primary methods and reference materials for chemical measurements and research in metrology to support different sectors in chemistry. 02/01/2020 Calibration of optical particle counters: First comprehensive inter-comparison for particle sizes up to 5 μm and number concentrations up to 2 cm−3 Konstantina Vasilatou, Stefan Horender and Kevin Auderset of project partner METAS recently provided an article for Metrologia; Calibration of optical particle counters: First comprehensive inter-comparison for particle sizes up to 5 μm and number concentrations up to 2 cm-3 The article was cowritten with project partners Kai Discherl of DFM, as well as Kenjiro Iida and Hiromu Sakurai of the National Metrology Institute of Japan (NMIJ) and National Institute of Advanced Industrial Science and Technology (AIST). The article reports on an inter-laboratory comparison for the calibration of light-scattering optical particle counters measuring the number concentration of airborne particles in the size range 300 nm – 5 μm. This comparison, registered as EURAMET pilot study Nr. 1453, is an important first step towards internationally recognized SI traceability in the measurement of low particle number concentrations encountered in clean-room facilities. The article is open access and is available to download here: https://iopscience.iop.org/article/10.1088/1681-7575/ab5c84 The article also fully acknowledges the EMPIR funding of the AEROMET project. 20/12/2019 Air Quality: Responding to new challenges Konstantina Vasilatou of project partner METAS recently gave an oral presentation at the Air Quality: Responding to new challenges conference which was held 10-11 December 2019 at the Royal Society of Chemistry in London. The presentation, “Towards the generation of synthetic ambient aerosols in the laboratory for calibration of PM monitors and low-cost sensors” was received at the conference as the UK Government launched its new Air Quality Strategy, tackling a broad range of sources including traffic, wood burning and agriculture. The conference looked at the increasing numbers of countries and cities that are making long-term commitments to phasing out petrol and diesel cars and increasing the focus on non-exhaust vehicle emissions, as well as current real-world exhaust emissions. As evidence of the health impacts of air pollution increase, cities are investigating and introducing new measures to meet EU Limit Values and protect their citizens. 08/11/2019 AEROMET at IMA2019; ‘Modern trends and applications in Instrumental Methods of Analysis’ Left: Dr. B.

NPL participated as a member of both AQUILA and AEROMET. The report is also available from our Documents & Publications page. 12/12/2017 Jiří Šperka of the Czech Metrology Institute (CMI) recently contributed a poster presentation at the European Aerosol Conference, August 27 – September 1, 2017 at the University of Zürich. Jiří’s presentation focused on the real and virtual atomic force microscopy measurements of regular and non-regular particles in combination with their evaluation in Gwyddion software (see http://gwyddion.net/). The real atomic force microscopy measurements were performed on regular polymer microspheres (nominated diameter 100 nm and 296 nm) and non-regular gold nanorods (dimensions 25 nm x 47 nm – D x L). Generation of virtual particles was also done in Gwyddion software. This study performed on particles with well-known parameters is important for precise understanding of atomic force microscopy measurements of real aerosol particles.
