Geographic and Temporal Variability of atmospheric surface Ammonia (NH3) in France, Belgium, and the Netherlands (2015 – 2023) across different land-use types: Insights from Ground-Based and combined Satellite Observations. Open
This research study analyzes atmospheric ammonia (NH₃) surface concentrations in France, Belgium (Flanders region), and the Netherlands, highlighting their geographic, temporal, and diel variability from 2015 to 2023 using ground-based mea…
Do rural background sites capture changes in primary PM2.5 emissions at the national scale? Recent trends in PM2.5 and its main components in metropolitan France. Open
Trends in daily PM2.5 mass concentrations were assessed at 5 rural background sites in France over the period 2014-2021, together with major particulate components associated with (i) anthropogenic emissions including fossil fuels (FF) and…
The Massive Open Online Course: 'Atmospheric Research Infrastructures: Sharing the Future of Our Atmosphere' as an Innovative Tool for Atmospheric Science & Climate Change Education Open
As part of the ATMO-ACCESS project, an innovative two-week Massive Open Online Course (MOOC) was hosted on the FUN (France Université Numérique) MOOC platform from January 20 to February 16, 2025. This course offered an engaging and intera…
How COVID-19 related policies reshaped organic aerosol source contributions in central London Open
Particulate matter (PM) poses both health and climate risks. Understanding pollution sources is therefore crucial for effective mitigation. Positive Matrix Factorization (PMF) of Aerosol Chemical Speciation Monitor (ACSM) data is a powerfu…

Air quality on UK diesel and hybrid trains Open
Concentrations of particulate matter (PM10, PM2.5), ultrafine (UFP), particle number (PNC), black carbon (BC), nitrogen dioxide (NO2) and nitrogen oxides (NOX) were measured in train carriages on diesel and bi-mode trains on inter-city and…
Aerosol composition at EMEP remote sites in France : mass balance and de-weathered trends of PM2.5 and its main components Open
Atmospheric particulate matter with an aerodynamic diameter < 2.5 µm (PM2.5) is associated with adverse effects on the climate system, the human health, vegetation and the ecosystems. The World Health Organization (WHO) lowered the guideli…
Atmospheric ammonia in-situ long-term monitoring: review worldwide strategies and recommendations for implementation Open
Ammonia (NH3) is the major alkaline gas in the atmosphere and the third most abundant N-containing species, after N2 and N2O. It plays an important role in N deposition processes, responsible of several damages on ecosystems, and it is als…
Five-year PM Chemical Composition and Organic Aerosol (OA) Sources in a European Megacity, London Open
Improving air quality in urban areas is essential since 97% of European cities exceed the annual PM2.5 value of the WHO guidelines (10 μg/m3). Therefore, in order to mitigate adverse health outcomes of air pollutants, it is extremely impor…
Long-term trends in particulate matter from wood burning in the United Kingdom: Dependence on weather and social factors Open
Particulate matter from wood burning emissions (Cwood) was quantified at five locations in the United Kingdom (UK), comprising three rural and two urban sites between 2009 and 2021. The aethalometer method was used. Mean winter Cwood conce…

Sources of particle number concentration and noise near London Gatwick Airport Open
There is increasing evidence of potential health impacts from both aircraft noise and aircraft-associated ultrafine particles (UFP). Measurements of noise and UFP are however scarce near airports and so their variability and relationship a…
Source attribution and quantification of atmospheric nickel concentrations in an industrial area in the United Kingdom (UK) Open
Pontardawe in South Wales, United Kingdom (UK), consistently has the highest concentrations of nickel (Ni) in PM10 in the UK and repeatedly breaches the 20 ng m-3 annual mean EU target value. Several local industries use Ni in their proces…
Atmospheric microplastic deposition in an urban environment and an evaluation of transport Open
Microplastics are a global environmental issue contaminating aquatic and terrestrial environments. They have been reported in atmospheric deposition, and indoor and outdoor air, raising concern for public health due to the potential for ex…
A tale of two cities: is air pollution improving in Paris and London? Open
Paris and London are Europe's two megacities and both experience poor air quality with systemic breaches of the NO2 limit value. Policy initiatives have been taken to address this: some European-wide (e.g. Euro emission standards); others …
Fetal growth, stillbirth, infant mortality and other birth outcomes near UK municipal waste incinerators; retrospective population based cohort and case-control study Open
We found no evidence that exposure to PM10 from, or living near to, an MWI operating to current EU standards was associated with harm for any of the outcomes investigated. Results should be generalisable to other MWIs operating to similar …
