Observations of Ground-level Ozone and NO2 in Northernmost Sweden, Including the Scandian Mountain Range
- 2009
-
Ingår i: Ambio. ; 38:8, s. 448-451
-
Tidskriftsartikel (refereegranskat)abstract
- Ozone was measured using passive diffusion samplers at alpine Latnjajaure (980 m above sea level [asl]) in the northern Scandian Mountain Range during spring and summer 2006–2008, and year-round at three further sites in northernmost Sweden 2004–2008. These observations were compared with ozone concentrations from three permanent monitoring stations using ultraviolet absorption instruments. Ozone concentrations at Latnjajaure were higher than at the closest monitoring site, illustrating the importance of high elevation for ozone. At the northern sites the ozone spring peak was more pronounced, higher, and earlier (April maximum) compared to a site in south Sweden (May maximum). During summer, ozone concentrations were higher in south Sweden. Presently, the growing season largely starts after the ozone spring peak in north Sweden but is likely to start earlier in the future climate. This could lead to an increased risk for ozone effects on vegetation if the current yearly ozone cycle persists.

Tidskriftsartikel (refereegranskat)abstract
- Ongoing urban exploitation is increasing pressure to transform urban green spaces, while there is increasing awareness that greenery provides a range of important benefits to city residents. In efforts to help resolve associated problems we have developed a framework for integrated assessments of ecosystem service (ES) benefits and values provided by urban greenery, based on the ecosystem service cascade model. The aim is to provide a method for assessing the contribution to, and valuing, multiple ES provided by urban greenery that can be readily applied in routine planning processes. The framework is unique as it recognizes that an urban greenery comprises several components and functions that can contribute to multiple ecosystem services in one or more ways via different functional traits (e.g. foliage characteristics) for which readily measured indicators have been identified. The framework consists of five steps including compilation of an inventory of indicator; application of effectivity factors to rate indicators' effectiveness; estimation of effects; estimation of benefits for each ES; estimation of the total ES value of the ecosystem. The framework was applied to assess ecosystem services provided by trees, shrubs, herbs, birds, and bees, in green areas spanning an urban gradient in Gothenburg, Sweden. Estimates of perceived values of ecosystem services were obtained from interviews with the public and workshop activities with civil servants. The framework is systematic and transparent at all stages and appears to have potential utility in the existing spatial planning processes.

Urban NO2 and NO pollution in relation to the North Atlantic Oscillation NAO
- 2011
-
Ingår i: Atmospheric Environment. - : Elsevier BV. - 1352-2310. ; 45:4, s. 883-888
-
Tidskriftsartikel (refereegranskat)abstract
- The North Atlantic Oscillation (NAO), a measure of the strength of the zonal wind across the North Atlantic Ocean, strongly influences weather conditions in NW Europe, e.g. temperature, precipitation and wind, especially during winter. It was hypothesised that elevated concentrations of nitrogen oxides in Gothenburg would be enhanced during negative NAO index (NAOI) conditions, representing more anticyclonic weather situations and thus leading to limited air mixing in the urban atmosphere, than situations with NAOI > 0. Hourly wintertime (DecembereFebruary) concentrations (1997e2006) of NO2, NO, air pressure, temperature and wind direction from an urban rooftop (30mabove street level) in the centre of the City of Gothenburg were analysed in relation to NAOI. Air pressure, the average concentration of nitrogen oxides (NOx ¼ NO2 þ NO), as well as the fraction of hourly NO2 and NO concentrations exceeding 90 mg m_3 and the fraction of daily NO concentrations exceeding 60 mg m_3, were significantly and negatively related to NAOI. Air temperature was positively correlated with NAOI. Southerly and westerly winds were more common in months with positive NAOI, while easterly and northerly winds were overrepresented in months with negative NAOI. High pollution concentrations dominantly occurred in situations with northerly and easterly wind directions. High NO2 and NO concentrations were associated with negative NAOI, especially in the morning when the traffic rush coincided with restricted air mixing. Over the tenyear period there were trends for more negative NAOI and increased time fractions with hourly NO2 concentrations exceeding 90 mgm_3. The conclusion of this study is that a climate shift towards higher or lower NAOI has the potential to significantly influence urban air pollution in North-West Europe, and thus the possibility to reach air quality standards, even if emissions remain constant.

Climate variability and land-use change in Danangou watershed, China
- 2005

Tidskriftsartikel (refereegranskat)abstract
- With global concern on climate change impacts, developing countries are given special attention due their susceptibility. In this paper, change and variability in climate, land use and farmers’ perception, adaptation and response to change are examined in Danangou watershed in the Chinese Loess Plateau. The first focus is to look at how climate data recorded at meteorological stations recently have evolved, and how farmers perceived these changes. Further, we want to see how the farmers respond and adapt to climate variability and what the resulting impact on land use is. Finally, other factors causing change in land use are considered. Local precipitation and temperature instrumental data and interview data from farmers were used. The instrumental data shows that the climate is getting warmer and drier, the latter despite large interannual variability. The trend is seen on the local and regional level. Farmers’ perception of climatic variability corresponds well with the data record. During the last 20 years, the farmers have become less dependent on agriculture by adopting a more diversified livelihood. This adaptation makes them less vulnerable to climate variability. It was found that government policies and reforms had a stronger influence on land use than climate variability. Small-scale farmers should therefore be considered as adaptive to changing situations, planned and non-consciously planned.

- 2021
-
Ingår i: International Emergency Nursing. - : Elsevier. - 1755-599X .- 1878-013X. ; 59
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Collaborative Health Care (CHC) is a unique model in which ambulance services, home health care, hospital care and the national telephone helpline for healthcare in Sweden – Swedish health care direct (SHD1177) collaborate to provide the fastest possible health care for inhabitants living in eleven municipalities in western region of Sweden. Aim: To explore how patients experience and perceive health care received in the CHC. Method: Qualitative descriptive study using open-ended individual telephone interviews with fifteen community dwelling persons with experiences of care throughthe model CHC were conducted. Results: Two main categories and six subcategories were identified. The category “Thoughts of time in regard to acute health care” include “CHC leads to shorter waiting time for health care”, “Knowledge about the staff working hours” and “To alert or not alert”. The category “Thoughts on unplanned health care from CHC” involved “Receiving health care in my home”, ”Coordination from SHD1177 surprises” and “Accessibility of health care values higher than continuity”. Conclusion: Integrated health care models such as CHC are time saving and highly appreciated by community dwelling persons. The benefits of provision of coherent health care like in CHC, addresses the need to implement innovative integrated healthcare models in today's health care.

Marknära ozon i södra Sverige. Utveckling av en manual för bedömning av överskridanden av målvärden.
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- På uppdrag av Länsstyrelserna i O, N, M, G, F, K samt H län har IVL Svenska Miljöinstitutet och Göteborgs Universitet genomfört en studie av förekomsten av marknära ozon i södra Sverige. Variationen i ozonförekomsten från kust och inåt landet har undersökts genom timvisa mätningar av ozonhalter och meteorologi med ett mobilt mätsystem i Skåne. Dessutom har kompletterande, månadsvisa mätningar bedrivits av medellufthalter av ozon och kvävedioxid samt temperatur. Vidare har de timvisa ozonmätningar som bedrivs vid Asa, SLU´s försökspark strax norr om Växjö, utvärderats med avseende på jämförelser med andra timvisa ozonmätningar som bedrivs i södra Sverige. Slutligen har praktiskt inriktad manual utarbetats för att möjliggöra länsvisa, yttäckande bedömningar av den årliga ozonförekomsten i relation till förekommande målvärden.

Past, present and future concentrations of ground-level ozone and potential impacts on ecosystems and human health in northern Europe
- 2017
-
Ingår i: Science of the Total Environment. - : Elsevier BV. - 0048-9697. ; 576, s. 22-35

Tidskriftsartikel (refereegranskat)abstract
- This reviewsummarizes newinformation on the current status of ground-level ozone in Europe north of the Alps. There has been a re-distribution in the hourly ozone concentrations in northern Europe during 1990–2015. The highest concentrations during summer daytime hours have decreased while the summer night-time and winter day- and night-time concentrations have increased. The yearly maximum 8-h mean concentrations ([O3]8h,max), a metric used to assess ozone impacts on human health, have decreased significantly during 1990–2015 at four out of eight studied sites in Fennoscandia and northern UK. Also the annual number of days when the yearly [O3]8h,max exceeded the EU Environmental Quality Standard (EQS) target value of 60 ppb has decreased. In contrast, the number of days per year when the yearly [O3]8h,max exceeded 35 ppb has increased significantly at two sites, while it decreased at one far northern site. [O3]8h,max is predicted not to exceed 60 ppb in northern UK and Fennoscandia after 2020. However, theWHO EQS target value of 50 ppb will still be exceeded. The AOT40 May– July and AOT40 April–September metrics, used for the protection of vegetation, have decreased significantly at three and four sites, respectively. The EQS for the protection of forests, AOT40 April–September 5000 ppb h, is projected to no longer be exceeded for most of northern Europe sometime before the time period 2040–2059. However, if the EQS is based on Phytotoxic Ozone Dose (POD), POD1, it may still be exceeded by 2050. The increasing trend for low and medium range ozone concentrations in combination with a decrease in high concentrations indicate that a new control strategy, with a larger geographical scale than Europe and including methane, is needed for ozone abatement in northern Europe.
