Cyclic volatile methyl siloxanes in the terrestrial and aquatic environment at remote Arctic sites
Cyclic volatile methyl siloxanes (cVMS) are widely used chemicals with high emissions to the atmosphere due to their volatility. They are found in the Arctic atmosphere, indicating potential for long-range transport. This study examined the potential for deposition of cVMS (D4, D5, D6) to surface media via snow in Arctic regions. Results showed low cVMS levels in vegetation, soil, sediment, and marine biota. D4 was detected above detection limits but generally below quantification limits, while D5 and D6 were generally not detected. This aligns with current research, suggesting negligible cVMS input from atmospheric deposition via snow and snow melt.

CZ0049 - Activity 2. Implementation of a secondary aerosol module in the CAMx model. NILU TR
The objective of project CZ0049 is to improve the characterisation of particulate matter, especially the formation and identification of secondary particles. This report presents our achievements in Activity 2 "Implementation of a secondary aerosol module in CAMx". We have reviewed available SOA smog chamber experiments from the literature and created a new parameterisation for formation of anthropogenic secondary organic aerosols. The new parameterisation has been implemented in the chemistry transport model CAMx. A detailed description of the work, including source code implementation, is given in the report.
