VKM assessed the potential risks to biodiversity in Norway associated with the import and release of biocontrol agents for management of house flies and stable flies in poultry farms, pig or sheep barns, cattle feedlots, and horse stables. Effective control of filth flies requires repeated releases of up to one million mass-reared individuals, but recent permits have restricted releases to lower numbers. Risk assessments were completed for the dump fly Hydrotaea aenescens, the parasitoid wasps Spalangia cameroni, S. endius, Nasonia vitripennis, Muscidifurax raptor, M. raptorellus and M. zarapator, and the hister beetle Carcinops pumilio. Nasonia vitripennis is a native species in Norway, C. pumilio is a non-native species that is widely established in Norway, and S. cameroni occurs on pig farms in southern Norway. Hydrotaea aenescens and M. raptor have been detected in low numbers, whereas S. endius, M. raptorellus and M. zaraptor have not been reported in Norway. The biological control agents are generalist predators and parasitoids that could affect native species through six impact mechanisms from the Environmental Impact Classification for Alien Taxa: competition, predation, hybridization, disease transmission, parasitism, and indirect effects. No impacts on native biodiversity have been documented where the non-native species occur in Norway or elsewhere. The potential for establishment and spread is low because the non-native species are associated with manmade habitats, have poor dispersal ability, and are warm-adapted species unlikely to cope with cold winters. Mitigation measures can reduce risks during import from commercial suppliers and releases in farms and stables, whereas surveillance programs could detect unexpected changes in insect communities. VKM concludes that the risks to native biodiversity in Norway are likely to be low from use of these biocontrol agents for management of pest flies in animal production facilities.

Abstract Indoor air quality can be improved by coatings that adsorb harmful volatile organic compounds (VOCs). In the present work, bio-based and VOC-adsorbing wood coatings were fabricated from polyphenols extracted from spruce bark, biochar produced from mixtures of spruce and pine bark, and a polyamine crosslinker. The bark-based biochar was doped with a catalyst (MnO 2 ) to enable continuous elimination of the adsorbed VOCs so that the coatings would not become saturated. The coatings formed a homogenous and smooth layer that covered the whole surface of the wood and showed excellent adhesion to the substrate, while their VOC removal efficiency was dependent on the pollutant type and the coating weight. The best performance was achieved toward formaldehyde, followed by chloroform and methyl ethyl ketone. Thick coatings (200–220 g/m 2 ) reached a formaldehyde removal of 62%, with the coating base and the biochar contributing nearly equally to the VOC removal. Overall, the bark-based coatings showed good potential for improving indoor air quality, but the surface wettability of the coated spruce wood was high. Despite the presence of biochar and nitrogen-containing aromatic compounds, the coatings did not appear to improve the reaction to fire of the wood.

Før-og-nå-fotopar kan være et godt virkemiddel for å vise endringer i våre hverdagslandskap, og de kan være grunnlag for ettertanke: • Hvorfor har det blitt slik? • Var det slik man ønsket eller tenkte at det skulle bli? • Ønsker eller trenger vi mer av slike endringer, her eller på andre steder? • Eller ønsker vi å stoppe eller reversere utviklingen? Når du har et foto fra et sted du kjenner til, kan det være lærerikt å prøve å ta bildet «på nytt».
