Bangladesh Air Pollution Management (BAPMAN). 6 Month Project Progress Report. August 2010 - January 2011. NILU OR

Randall, S.

Section 6.1 of the contract (BGD-3125 BGD-091066) between NORAD and NILU regarding Institutional Cooperation with the Bangladesh Ministry of Environment and Forest/Department of Environment (DOE) states that a progress report should be submitted semi-annually to NORAD. This report highlights the status of the project for the first six months of the project, August 2010 -January 2011. The project can be considered in good standing, with no major issues or deviations to report.

An amine based CO2 capture plant may cause harmful emissions to the atmosphere. Amines and degradation products from reactions in the process and in the atmosphere are of particular concern, but there is limited knowledge about the behaviour and potential effects of these chemical compounds. The substances produced can pose a risk to the environment and human health. This report includes a review of Integrated Testing Strategies (ITS) including (Q)SAR and a data gap analysis on current knowledge level on nitrosamines and nitramines in relation to the information demands for the risk assessment within REACH.

Atmospheric Degradation of Amines (ADA). Summary report: Photo-oxidation of methylamine, dimethylamine and trimethylamine. CLIMIT project no. 201604. NILU OR

Nielsen, C.J.; D'Anna, B.; Karl, M.; Aursnes, M.; Boreave, A.; Bossi, R.; Bunkan, A.J.C.; Glasius, M.; Hallquist, M.; Hansen, A.M.K.; Kristensen, K.; Mikoviny, T.; Maguta, M.M.; Müller, M.; Nguyen, Q.; Westerlund, J.; Salo, K.; Skov, H.; Stenstrøm, Y.; Wisthaler, A.

The atmospheric gas phase photo-oxidation of methylamine (CH3NH2), dimethylamine ((CH3)2NH) and trimethylamine ((CH3)3N) has been studied under pseudo natural conditions at the European Photochemical Reactor, EUPHORE, in Valencia, Spain. Major products in the photo-oxidation were imines (methanimine and N-methyl-methanimine) and amides (formamide, N-methyl formamide and N,N-dimethyl formamide). Total aerosol yields obtained in EUPHORE experiments were between 8 and 14%. Mimicking conditions at Mongstad results in a steady-state nitrosamine concentration of less than 0.6 % of photo-oxidized dimethylamine and less than 1.1 % of photo-oxidized trimethylamine. For rural regions it is predicted that the formation yield of the corresponding nitramine in the atmospheric oxidation of CH3NH2, (CH3)2NH and (CH3)3N is less than 0.4 %, 2.5 % and 5 %, respectively. The major uncertainties in the current understanding of the fate of amines emitted to the atmosphere are related to night-time chemistry, to the chemistry of imines, and to chemistry in the aqueous aerosol.
