Indoor air quality investigation sector E3-02. NILU OR
Abu Dhabi Municipality has chosen the Norwegian Institute for Air Research (NILU) to perform indoor air quality investigation for six buildings in sector E3-02 (one School, one Mosque, one commercial building and three Residential building).
The main goal of this task is to define the main pollutants that could be found in the buildings and to define the status of existing buildings with respect to indoor air quality.
The results of measurements that were conducted at different locations have shown that there was a wide mold growth in the duct of ventilation system due to poor maintenance in all studied buildings, also that carbon dioxide (CO2) and voltaic organic compound (VOC) are considered the main pollutants that could found and affect the indoor air quality in these buildings.
In most of tested locations, the CO2 concentration has exceeded the standard limit, the readings were very high in the school, mosque, and to a lesser extent in commercial building.

Assessment of traffic noise and mitigation options for Al Salam Street. NILU OR
Acting on request from the Abu Dhabi Municipality, Norwegian Institute for Air Research has been asked by the Abu Dhabi Municipality to evaluate the current noise levels on Salam Street and recommend mitigation measures to control the noise.
NILU provided traffic count data collected near the Sheikh Zayed Bridge and these were used in conjunction with an acoustic model to predict the existing noise conditions at 126 sensitive receptor locations.The predicted sound levels were compared to measured sound levels collected at seven (7) locations along Al Salam Street to validate the results of the modelling. This comparison showed strong correlation between the modelled and measured results.
Several mitigation options provided by NILU were incorporated into subsequent runs of the baseline model in order to predict the effectiveness of each option. It was found that the installation of a 5 m barrier adjacent to the outbound lanes of Al Salam Street would be the most effective individual mitigation option.

Indoor air quality study for the Norwegian Embassy in Abu Dhabi. NILU OR
NILU has been asked by the Norwegian Embassy in Abu Dhabi to carry out an indoor air quality(IAQ) study. The results have shown that there is a big variation in the temperatures ( ¿10 C) between the monitored locations in the office. Data analysis from employees survey about indoor air have shown that employees do not feel comfortable with the temperature conditions. In addition mould growth was detected in Ambassador¿s office.
CO2 concentration exceeded the acceptable limit in two locations, because the ventilation system is not capable to provide sufficient amount of fresh air to the number of occupants. The conclusion was that the main problem was related to the unbalanced ventilation system creating improper air circulation leading to high CO2 concentrations and large differences in temperatures.

BASELINE ambient air quality monitoring at KPIZ, Abu Dhabi. NILU OR
Abu Dhabi Ports Company (ADPC) is a master developer and regulator of ports in Abu Dhabi Emirate. The development of Khalifa Port and Industrial Zone (KPIZ) is one of the major strategic projects undertaken by ADPC. The KPIZ is located at Al Taweelah, midway between Dubai and Abu Dhabi City.
The survey aims to establish background AAQ levels at the project site and to compare the measured data with pertinent ambient air quality standards.
This report provides a summary of ambient air quality and meteorological measurements carried out during the 6 month period 24 August 2010 to 24 February 2011 which is referred to as Report No. 6.

Deposition of major inorganic compounds in Norway 2007-2011. NILU OR
The total deposition of sulphur and nitrogen compounds in Norway during the period 2007-2011 has been estimated on the basis of available measurement data for concentrations and precipitation. Deposition of non-marine base cations is also estimated. Results are compared with previous estimates for 2002-2006.

The Bangladesh Air Pollution Management (BAPMAN) project is an institutional-building project where NILU lends the necessary Air Quality Management (AQM) tools and associated training to the Clean Air and Sustainable Environment (CASE) program at the Department of Environment (DoE). Mission 6 of the BAPMAN project occurred in Dhaka from 13-18 October 2012 where the target of the mission was to continue Task 2 training (CAMS QA/QC), continue Task 1 training (AirQUIS monitoring), and to develop a data retrieval interface for the AirQUIS server (Task 3).

The NORTRIP model is the result of research efforts carried out by a number of Nordic institutes to improve our understanding and ability to model non-exhaust traffic emissions and has been developed through the Nordic Council of Ministers project NORTRIP (NOn-exhaust Road Traffic Induced Particle emissions). The NORTRIP model is a process based non-exhaust emission model that is intended for application without site specific empirical factors. It takes into account direct wear emissions, the build up of mass on the road surface, the suspension of this mass, as well as the application and suspension of salt and sand. It combines a road dust sub-model with a road moisture sub-model in order to properly describe the retention of dust on the road surface. The model can be applied for assessment purposes and for the management and evaluation of abatement strategies regarding road wear, salting and sanding. The model development and its documentation, along with its application to a large number of Nordic datasets, is described in detail in this report.

NORTRIP emission model user guide. NILU TR
The NORTRIP emission model has been developed at NILU, in conjunction with other Nordic institutes, to model non-exhaust traffic induced emissions. This short summary document explains how to run the NORTRIP model from the MATLAB environment or by using the executable user interface version. It also provides brief information on input files and the model architecture.
