HTAP3 Fires: towards a multi-model, multi-pollutant study of fire impacts
Open biomass burning has major impacts globally and regionally on atmospheric composition. Fire emissions include particulate matter, tropospheric ozone precursors, and greenhouse gases, as well as persistent organic pollutants, mercury, and other metals. Fire frequency, intensity, duration, and location are changing as the climate warms, and modelling these fires and their impacts is becoming more and more critical to inform climate adaptation and mitigation, as well as land management. Indeed, the air pollution from fires can reverse the progress made by emission controls on industry and transportation. At the same time, nearly all aspects of fire modelling – such as emissions, plume injection height, long-range transport, and plume chemistry – are highly uncertain. This paper outlines a multi-model, multi-pollutant, multi-regional study to improve the understanding of the uncertainties and variability in fire atmospheric science, models, and fires' impacts, in addition to providing quantitative estimates of the air pollution and radiative impacts of biomass burning. Coordinated under the auspices of the Task Force on Hemispheric Transport of Air Pollution, the international atmospheric modelling and fire science communities are working towards the common goal of improving global fire modelling and using this multi-model experiment to provide estimates of fire pollution for impact studies. This paper outlines the research needs, opportunities, and options for the fire-focused multi-model experiments and provides guidance for these modelling experiments, outputs, and analyses that are to be pursued over the next 3 to 5 years. The paper proposes a plan for delivering specific products at key points over this period to meet important milestones relevant to science and policy audiences.

Denne rapporten presenterer resultatene fra en spørreskjemabasert undersøkelse i Wuhan. Ut fra 1086 gyldige spørreskjemaer samlet inn fra offentligheten, viste resultatene at de fleste deltakerne: 1) er unge studenter med bachelorgrad, 2) har grunnleggende kunnskaper om luftforurensningsproblemer i Wuhan, 3) uttrykte vilje til å lære mer om luftkvalitetsrelatert kunnskap; 4) foreslo å styrke miljøholdningsskapende aktiviteter i Wuhan, og 5) på det sterkeste appellere til de lokale myndighetene til å gjennomføre tiltak for å bedre luftkvaliteten.

Worldwide, edible fish are well studied for plastic occurrence. Microplastic (MP) occurrence in edible tissues raises concern for the organism’s health, but also on food safety. In the Arctic region, MP occurrence in other tissues than the digestive tract of fish has not been published yet. Plastic-related chemicals such as UV stabilisers (UVS) were also scarcely studied in Arctic biota. Our objectives were to (1) provide data on MP occurrence in Atlantic cod (Gadus morhua) fillets, (2) quantify UVS in the same fillets, and (3) provide estimations of both MP and UVS intake by Norwegian and European consumers through cod consumption. Twenty individuals were collected in the Barents Sea, south-west of Svalbard. They were dissected onboard and a piece of fillet was used for the extraction of MPs in the lab. Particles’ identification was performed by µRaman spectroscopy. MPs were found in 45 % of the fillets, with an average of 0.25 MP/g ww. Only one UV stabiliser (UV-326) was detected, in four fillets. Based on consumption data of cod, an average Norwegian man and woman would ingest 20.8 and 33.5 MPs weekly, respectively. Considering a European diet, a weekly intake of 8 MPs and a yearly intake of 403 MPs through cod consumption was calculated. The impacts of MP exposure to humans are unknown. Through this study, rather than to raise potential risks of consuming fish, we aimed to trigger further research on microplastics occurrence in seafood, i.e. in the edible tissues of aquatic animals.
