Literature review of Particulate Matter (PM) from transport with a special focus on organic aerosols

by Patricia Gouveia | Feb 23, 2022

Several recent scientific studies on urban air quality have suggested that air quality modelling based on current emission inventories for mobile sources systematically underestimates the contribution of these sources to ambient particulate matter (PM) levels, and...

How Covid-19 lockdown affected air pollution in Europe — a multi-city analysis (Concawe Review 30.1)

by Victoire de Marans | Jun 25, 2021

Concawe has undertaken a city-level analysis to quantify the ways in which the Covid-19 lockdown measures have had an impact on air quality in Europe. This article presents the results of the analysis for particulate matter (PM2.5), nitrogen dioxide (NO2) and ozone...

Understanding the process of setting air quality limit values and the associated compliance challenge—the ozone study (Concawe Review 30.1)

by Victoire de Marans | Jun 25, 2021

The European Commission is proposing to revise air quality standards to align them more closely with the World Health Organization (WHO) guidelines. This article focuses on O3, and assesses how current and projected compliance trends will change under the current EU...

Literature review on emissions of semi- and intermediate volatile organic compounds and formation of organic aerosols with focus on the refinery sector

by Marine Teixidor | Feb 12, 2021

Organic aerosols (OA) are an important component of ambient particulate matter (PM) but their origin and formation is not well understood. Traditionally, OA have been described by two classes: a) primary organic aerosol (POA) and b) secondary organic aerosol (SOA)....

Results of a comparative pilot field test study of a first generation Quantitative Optical Gas Imaging (QOGI) system

by Patricia Gouveia | Oct 28, 2020

Quantitative optical gas imaging (QOGI) is a new system to detect fugitive emission sources and quantify their mass release rates. This report presents an evaluation of QOGI technology compared to other techniques (Sniffing/EPA Method 21 and high flow sampling (HFS)),...
