Ambient air pollution screening study in Dhaka and Chittagong. 16 February - 01 March 2013. NILU OR

Randall, S.; Sivertsen, B.; Schneider, P.; Paul, A.; Rahman, Md. A.; Hasan, Md. M.

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.

Bangladesh Air Pollution Studies (BAPS): Task 5 (Industrial emission estimates). Final report. NILU OR

Rahman, M.M.; Begum, D.A.; Ahmed, N.; Randall, S.; Sivertsen, B.; Ahammad, S.S.

As part of the Bangladesh Air Pollution Studies (BAPS) under Clean Air & Sustainable Environment Project (CASE), stack emission measurements were made on several days at a steel mill and a ceramic industry, both located in the outskirts of Dhaka city. The measurements were made by ChE-BUET Team of the Bangladesh University of Engineering & Technology (BUET), Dhaka. The team has access to all the sophisticated equipment and expertise for emission measurements at industrial stacks. All equipment used were calibrated as per manufacturers' instructions. USEPA/ASTM approved methods were followed for all measurements.

Investigation of outdoor textiles with respect to determine the content of ionic perfluorinated substances (PFASs). Evaluation of results. NILU OR

Hanssen, L.; Herzke, D.

NILU has on behalf of the Norwegian Environment Agency determined the concentration of ionic perfluorinated substances (PFASs), including PFOA, in outdoor clothing. Of the investigated 12 items, no PFAS could be detected at all in only 2 of them (sample 8 and 12). Four samples contained PFOA exceeding the limit of 1 µg/m2. The quality assurance where three replicates of one sample were extracted had a relative standard deviation (RSD) less than 10% for all detected substances except one (PFTrDA). Other quality measures such as recovery calculations and blanks shows that the method used for extraction is suitable for these types of matrices and substances. PFOS was not present in the items investigated, indicating that the textile industry manages to effectively avoid PFOS in their production processes.
