Interim air quality maps of EEA member and cooperating countries for 2023. PM, O3, and NO2 spatial estimates

Horálek, Jan; Vlasakova, Leona; Schreiberova, Marketa; Schneider, Philipp; Benesova, Nina; Vlcek, Ondrej

The report presents interim 2023 maps for PM10 annual average, PM2.5 annual average, O3 indicator peak season average of maximum daily 8-hour means, and NO2 annual average. The maps have been produced based on the 2023 non-validated E2a (UTD) data of the AQ e-reporting database, the CAMS Ensemble Forecast modelling data and other supplementary data. Together with the concentration maps, the inter-annual differences between 5-year average 2018-2022 and 2023 are presented (using the 2018-2022 regular and the 2023 interim maps), as well as basic exposure estimates based on the interim maps.

Air quality in Sandefjord, Norway. November 2021 – August 2023.

Salamalikis, Vasileios; Castell, Nuria

This report examines the air quality patterns in terms of particulate matter with a diameter less than 2.5 μm (PM2.5) in Sandefjord, Norway. PM2.5 was monitored through five low-cost sensors in hourly resolution from November 2021 to August 2023. The sensors’ reliability is high, with consistent PM2.5 measurements and similar variation over time. Occasional extreme PM2.5 was attributed to local contributions with higher values observed during cold months, or specific long-range transport events. Overall, Sandefjord maintained good air quality for most of the measurement period with daily PM2.5 levels below the air quality criteria. Residential heating activities (wood burning) is the most significant local source, being more pronounced during winter.

Environmental pollutants in the terrestrial and urban environment 2023

Heimstad, Eldbjørg Sofie; Moe, Børge; Davie-Martin, Cleo Lisa; Borgen, Anders; Enge, Ellen Katrin; Nordang, Unni Mette; Løge, Oda Siebke; Harju, Mikael; Bæk, Kine; Hanssen, Linda

Samples from the urban terrestrial environment in the Oslo area were analysed for metals and a large number of organic environmental pollutants. The selected samples that were analysed were soil, earthworm, fieldfare egg, brown rat liver, roe deer liver, vegetation, honeybee, and Spanish slug. Biomagnification potential was estimated based on detected data for relevant predator-prey pairs.
