Airborne microplastics on the move: Urban Europe as a source to remote regions
This study presents a comprehensive assessment of unique parallel measurements of surface airborne and deposited microplastics (AMPs) across urban and remote sites in Norway, employing pyrolysis-GC/MS for polymer-specific analysis. MPs were detected in nearly all samples, with significantly higher concentrations and fluxes observed in urban areas like Oslo, where tire wear particles (TWP) dominated (>90 % of AMP mass). Seasonal peaks in TWP coincided with the transition to winter tires, while remote sites showed consistent but lower AMP levels, indicating long-range transport (LRT) from European source regions. Parallel measurements of suspended and deposited AMPs revealed consistent polymer signatures, highlighting common sources and transport pathways. Although urban TWP contributions to PM2.5 were generally low, episodic events reached up to 30 %, raising concerns about human exposure. The dual dataset enabled a robust cross-validation of atmospheric loading estimates and facilitated integration into advanced transport models for remote sites. Our findings confirm AMPs as significant components of urban air pollution and subsequent carriers of chemical and biological contaminants to remote regions, emphasizing the need for targeted monitoring and mitigation strategies.

Air quality zone delimitation in Norway. Evaluation and delimitation proposal. NILU OR
An evaluation of the air quality in Norway over the last five years has been performed to set up the basis for a new Air Quality zone (AQ-zone) delimitation for reporting to European Commission concerning compliance of air quality directives. Air pollution levels (i.e. PM10, NO2, SO2, CO, O3, benzene, heavy metals, B(a)P) have been assessed regarding exceedances of limit values, target values, Norwegian national targets, and upper/lower assessment thresholds (UAT/LAT) defined for the protection of human health, vegetation and/or natural ecosystems. The results from this evaluation complemented with information regarding background concentration levels in Norway have been used to define a new delimitation: 1) AQ-zone delimitation for PM10, NO2, NOx, benzene and B(a)P, 2) AQ-zone delimitation for SO2 and heavy metals, 3) AQ-zone delimitation for ozone and 4) AQ-zone delimitation for CO.

Air quality web portal in Dakar. Operational and editoral procedures. NILU OR
The current report presents the operational and editorial procedures for the Air Quality Web portal in Dakar, operated by the Centre de Gestion de la Qualité de l¿Air de Dakar (CGQA). The procedure to set up the Air Quality Index (AQI) in AirQUIS is described and illustrated in Annexe A. In Annexe B a short description of how AirQUIS calculates the AQI for the different measurement station types is given, as well as the procedure CGQA has to follow to determine the AQI for the whole Dakar city to be presented daily on the Air Quality Web portal. The operational and editorial procedures for the Air Quality Web portal in Dakar have been described by Aminata Diokhane, under supervision of NILU and validated by NILU.
