Johan Castberg-feltet i Barentshavet. Vurdering av utslipp til luft. NILU OR
Miljøkonsekvensene av fremtidige utslipp til luft fra Johan Castberg-feltet i Barentshavet er vurdert. Tidligere beregninger med WRF-EMEP-modellen er benyttet. CO2, CH4 og NMVOC er vurdert utfra deres bidrag til økt drivhuseffekt (klimagasser) der Johan Castberg er et middels stort felt i norsk sammenheng. Utslipp av NOx vil gi bidrag til eutrofiering og forsuring (ved avsetning), SOx gir bidrag til forsuring. Konklusjonen er at bidraget til eutrofiering og forsuring i Nord-Norge fra Johan Castbergfeltet ubetydelig. Økning i ozon, dvs N120, dvs. antall dager med 8-timers løpende middelverdi av O3 over 120 µg/m3 er eneste parameter der beregningene gir en viss økning, opp med 1 tilfelle fra 10. Utslipp av Black Carbon, dvs. sot er også vurdert. Det vurderes at klimaeffekten av installasjonene på Johan Castberg vil bli liten.

Ambient air pollution screening study in Dhaka and Chittagong. 16 February - 01 March 2013. NILU OR
As a part of the Bangladesh Air Pollution Studies (BAPS) project, a screening study of air pollution was performed in Dhaka and Chittagong with assistance from local university partners. The screening study work fell under Task 1 (Emissions Inventory) of the BAPS project.
The screening study was performed in Dhaka from 16 February - 26 February 2013, and Chittagong from 20 February - 01 March 2013. The main objective of the study was to gain an overview of the background concentrations and the spatial distribution of the air pollution in the Dhaka city and Chittagong city areas. This study is also following up on a similar study performed in Dhaka in February 2011. The screening study focused on the following gaseous components in Dhaka and Chittagong: Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2), and Ozone (O3). In addition, samples for persistent organic pollutants (POPs) were collected in Chittagong in connection with the study, which will be reported separately in fall 2013 under a different project.
