Concerns have been raised as to whether gunshot fumes induce prolonged reduced lung capacity or even cancer due to inhalation. Gunshot fumes from three different types of ammunition calibre 5.56 mm × 45 NATO were investigated. SS109 has a soft lead (Pb) core, while NM255 and NM229 have a harder steel core. Emissions from ammunitions were characterized with respect to particle number- and mass-size, and mass distribution, heavy metal content, and different gases. Lung epithelial cells were exposed to the fumes at the air liquid interface to elucidate cytotoxicity and genotoxicity. Irrespectively of ammunition type, the largest mass fraction of generated particulate matter (PM) had a size between 1 and 3 μm. The highest number of particles generated was in the size range of 30 nm. Fumes from NM255 and NM229 induced cytotoxic effects of which the emission from NM229 induced the highest effect. Fumes from NM229 induced a dose-related increase in DNA-damage. Significant effects were only achieved at the highest exposure level, which led to approximately 40% reduced cell viability after 24 h. The effect probably relates to the mass of emitted particles where the size may be of importance, in addition to emission of Cu and Zn. A complex mixture of chemical substances and PM may increase the toxicity of the fumes and should encourage measures to reduce exposure.

Towards the development of a commom EMEP global modeling framework. EMEP/MSC-W Technical report, 1/2008

The Pan-Eurasian Experiment Modelling Platform (PEEX-MP) is one of the key blocks of the PEEX Research Programme. The PEEX MP has more than 30 models and is directed towards seamless environmental prediction. The main focus area is the Arctic-boreal regions and China. The models used in PEEX-MP cover several main components of the Earth’s system, such as the atmosphere, hydrosphere, pedosphere and biosphere, and resolve the physical-chemical-biological processes at different spatial and temporal scales and resolutions. This paper introduces and discusses PEEX MP multi-scale modelling concept for the Earth system, online integrated, forward/inverse, and socioeconomical modelling, and other approaches with a particular focus on applications in the PEEX geographical domain. The employed high-performance computing facilities, capabilities, and PEEX dataflow for modelling results are described. Several virtual research platforms (PEEX-View, Virtual Research Environment, Web-based Atlas) for handling PEEX modelling and observational results are introduced. The overall approach allows us to understand better physical-chemical-biological processes, Earth’s system interactions and feedbacks and to provide valuable information for assessment studies on evaluating risks, impact, consequences, etc. for population, environment and climate in the PEEX domain. This work was also one of the last projects of Prof. Sergej Zilitinkevich, who passed away on 15 February 2021. Since the finalization took time, the paper was actually submitted in 2023 and we could not argue that the final paper text was agreed with him.

Towards operational satellite based atmospheric monitoring in Norway SatMoNAir. NILU OR
SatMoNAir prosjektet [NSC kontrakt nr. JOP.12.12.2] bygger på et tidligere NRS følgemiddelprosjekt kalt 'Roadmap towards EarthCARE and Sentinel 5 precursors', der NILU og met.no utviklet en strategi for å være forberedt på framtidige satellittobservasjoner knyttet til nasjonal klimaovervåkning, værvarsel og forskning. Det har blitt fokusert på tre områder: a.
Aerosol¿ klimaeffekter i Skandinavia og polare strøk, b. Bruk av satellitter i nasjonal overvåkning av ozonlaget, c. Satellittbaserte målinger av luftkvalitet til bruk i EMEP rapportering. Resultater fra dette arbeidet blir beskrevet i denne rapporten. Prosjektet har vært en viktig støtte for NILUs nasjonale overvåkning av klimagasser og aerosoler (Myhre et al., 2012) og atmosfærens ozonlag (Svendby et al., 2012). Resultater har også blitt rapportert til EMEP.
