Bangladesh Air Pollution Management (BAPMAN). Deliverable D4.1: Training program for health impact assessment and documentation of its implementation and results. NILU OR

Sundseth, K.; Randall, S.; Sivertsen, B.; Rahman, S.

The objective of the training workshop for Work segment 4 in the "Bangladesh Air Pollution Management" BAPMAN project, is to build local (DOE) capacity for developing an air quality management strategy for the future.

The training workshop was held at NILU, being presented by NILU air quality experts.

The purposes of the workshop were to produce information on the health consequences of air pollution in Dhaka that can be used by local expertise at DOE and in supporting Bangladeshi institutions in the assessment of health impacts. The workshop aimed at developing the fundamental expertise by which objectives and strategies for air quality management can be developed into the future.

Modelling non-exhaust emissions of PM10 in Oslo. Impact of the environmental speed limit using the NORTRIP model. NILU OR

Denby, B.R.; Sundvor, I.

This report was requested by the Norwegian Public Roads Administration (Statens vegvesen) to provide information concerning non-exhaust traffic emissions in Oslo and the impact of changes in environmental speed limits on these emissions. This report provides the results of calculations made with the dispersion model EPISODE coupled to the NORTRIP road dust emission model, a recently developed emission model for calculating non-exhaust emissions. The change in modelled emissions due to changes in environmental speed limit are calculated for two different speed scenarios, where 'speed limit' and 'realistic speed' changes are compared. In addition the impact of the environmental speed limit is compared to other road dust control measures involving studded tyre share and heavy duty vehicle reduction, taken from a previous report.

Chemical speciation of fine airborne particles in Abu Dhabi. NILU OR

Hak, C.; Lopez-Aparicio, S.

PM2.5 was sampled at two urban background sites in Abu Dhabi (Khalifa in the city of Abu Dhabi and Bida Zayed) and analysed chemically for further source identification and quantification. Understanding of source contributions to PM2.5 is a prerequisite for the formulation of effective control strategies for PM2.5 emissions.
For both sites, five source factors were identified. Long-range transported aerosol is the largest contributor (~41%) to average PM2.5 mass concentrations at both sites. It gradually forms from SO2, which is possibly emitted into ambient in the Arabian Gulf area, while it is transported to the sites. Mineral dust was found to be the second most important source, contributing ~25% at both sites. It represents an ubiquitous natural contribution of mainly regional origin to particulate matter in Abu Dhabi.
Other source contributions to particle concentrations found at Khalifa identified were: local traffic (15.1%), shipping/industry (10.5%) and sea salt (4.0%). The latter is a natural contribution.
At Bida Zayed, a mixed traffic/industry factor (13.2%) was found, as well as another two factors of natural origin, explaining 11.4% and 8.7%

Air quality zone delimitation in Norway. Evaluation and delimitation proposal. NILU OR

Lopez-Aparicio, S.; Tønnesen, D.

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.
