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.

Air Quality Plans and Measures. Analysis of data submitted from 2014 to 2020.
The submitted data were analysed with the aim to provide information to the EEA Member countries that can be used to improve their air quality management practices, and to give feedback on data quality and possible use. Previous studies in the framework of the Air Implementation Pilot (published in 2012 and 2013) made assessments of the measures and management practices but were not successful in defining the measures’ effectiveness, so the present report also looks into what kind of information can be obtained from the data.
In the period 2014 – 2020, 23 EEA member countries submitted at least one air quality plan. Most countries focus their plans on pollutants related to traffic: NO2 and/or PM10. Most measures target exceedances of NO2 (62 %), PM10 (26 %) and PM2.5 (10 %), and measures are reported that target exceedances of standards of benzo(a)pyrene, nickel and lead (all in PM10) as well as SO2. In one case, the measure is related to benzene.
« Traffic » is the main sector leading to exceedances, with 64 % of records, followed by « domestic heating » (14 %), « local industry » (10 %) and “Other” (8 %). The « Other » category when given further information could comprise a variety of sources including meteorology, agricultural residue burning, harbour activity or shipping.
The majority of the exceedances occurred in urban areas (65 %) followed by suburban areas (21 %), while 14 % of the exceedances addressed in the plans occurred in rural areas.
The available data consist of a large number of individual records (ranging from several hundreds to over 20 thousand depending on the reporting element) that in theory can be linked using unique identifiers. However, not all the records can be linked. While the basis for analysis can vary depending on which reporting segments are used, the overall results are consistent across the segments, and provide a very good overview of which air pollution abatement measures are taken by national and local authorities.

Air quality plan for improved air quality in Bergen. NILU rapport
The air quality plan will help to reduce the air pollution to a level that meets the requirements of the pollution regulations. This revised action plan includes air quality calculations for Bergen for NO2, PM10 and PM2.5 for the present situation (2015) and scenario calculations for the year 2021 following a business as usual (BAU) emission scenario. Mitigation scenario calculations of air quality in 2021, with the introduction of a new set of measures to control pollution levels Bergen, were also carried out. Based on the results of the calculations and in dialogue with Bergen municipality and stakeholders, a revised 10-point action program has been proposed to be addressed politically.

Air quality Ny-Ålesund. Monitoring of local air quality 2008-2010. Measurement results. NILU OR
A selected number of air pollutants has been monitored in Ny-Ålesund to map the local emissions of air pollutants and to map the air quality of the area.

Air quality near E6 at Jessheim. NILU OR
NILU has assesed air quality at a proposed site for a hospital close to E6 at Jessheim. Based upon traffic volume, emission factors and local meteorology, concentrations of NO2 and PM10 have been modelled. The results have been compared to 'Guidelines for air quality in area planning' and the 'Red' and 'Yellow' air quality areas have been presented on a map.

Air Quality Monitoring Project, Abu Dhabi City Municipality. Site Selection report. NILU OR
NILU has been selected by Abu Dhabi Municipality (ADM) to carry out the programme: ¿Air Quality Monitoring Network for Abu Dhabi City Municipality¿. One task of the project is to design a complete air quality monitoring network for the ADM Jurisdiction area.
ADM plays the role of the Sector Regulatory Authority (SRA) for the implementation of the Environment, Health and Safety Management System (EHSMS) in the Building and Construction Sector in the Greater City of Abu Dhabi.
In this light, NILU has selected a number of most appropriate sites to serve this purpose as well and came out with a number of plausible locations detailed further in the report.
This report describes the outcome of site selection survey which took place from 24. to 31. May 2011.
