Inert dispersion of a unitary emission has been combined with time dependent air chemistry to provide maximum impact of nitrosamines and nitramines in air and water for emissions from the amine absorber at TCM. The calculations show that likely case impact of nitrosamines and nitramines in air is less than 2 % of the recommended guideline value. The maximum concentrations in fresh water range from0.6 % to 3.2 % of the guideline depending on the use of absorbent and flue gas. The likely case impact show that air concentrations are a factor of 3 to 4 lower than the worst case, while water concentrations are be a factor from 16 to 22 lower than the worst case depending on the type of absorbent.

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.

Measurements of air quality and corrosion risk at the Railway Museum in Warsaw. NILU OR
Measurements of the concentration of SO2, of aerosol concentration in air and of the composition and mass of water soluble cations and anions were performed during four seasons, spring, summer, autumn and winter, at two locations of the Railway Museum in Warsaw: Central Warsaw and Sochazew, which is located 50 km west of Warsaw. The time of wetness was calculated from precipitation data available from the Warsaw Targowek meteorological station. The measurements indicated a low to medium corrosivity for the atmospheres, which is typical for northern European inland environments with low chloride concentrations and relatively low SO2 concentration. The measurements indicated that sulphur dioxide SO2 was the main pollutant which gave increased corrosion at the sites, especially in Sochaczew, and that the presence of chloride, Cl-, and sulphate, SO42-, in the aerosol at significant levels contributed to the corrosion. Higher levels of Cl-, SO42- and H+ were measured in Sochaczew than in central Warsaw. The ISO 9223 corrosion category for SO2 and Cl- was 0 in central Warsaw and 1 in Sochaczew, indicating a significant contribution to the corrosion from anthropogenic sources in Sochaczew. The values for SO2 are slightly higher, but the PM10 values are lower, than tolerable levels for immovable (i.e. outdoor) cultural heritage given in a European wide assessment performed for CAFÉ (EU programme: Clean Air For Europe). The main factor that increases the corrosion to a higher ISO category (2-3) at the locations is the relatively humid climate. A further reduction of air pollutants should further reduce the corrosion, but the largest potential protection effect would be from measures to shelter the objects form rain and reduce the humidity in the air around the objects, e.g. by moving vulnerable smaller objects or particularly valuable objects to the indoor or applying other options for sheltering.
