    This study presents the development and applications of regional and local scale models for use in integrated assessment of air pollution effects in conjunction with large-scale models. A regional deposition model called DAIQUIRI (Deposition, AIr QUality and Integrated Regional Information) for integrated assessment purposes in Finland was constructed, and regional matrices for nitrogen oxides and ammonia were developed from the results of the regional air quality model of the FMI. DAIQUIRI produced similar estimates of deposition from Finnish sources as the original model, and long-term trends and the average level of deposition estimated with DAIQUIRI were found comparable with the monitored deposition levels and trends. For the mid-nineties situation, the regional nitrogen modeling resulted in 9% to 19% (depending on the region compared) larger estimates of areas with acidity critical load exceedances than when using European scale nitrogen deposition modeling.In this work, also a method for estimating the impacts of local NOx emissions on urban and sub-urban ozone levels was developed and tested. The study concentrated on representing the destruction of ozone by fresh NO emissions in urban areas for future use in integrated assessment modeling of ozone control strategies. Correlation coefficients between measured daytime ozone values in the study area were found to improve from 0.64 (correlation between urban and surrounding rural measurements) to 0.85, on the average. The average correlation between daytime large-scale model estimates and urban site measurements was found to improve from 0.37 to 0.58.In the study, also integrated assessment model applications were carried out at European, national and local levels. The synergies between control strategies for CO2 and acidification and ozone formation in the case of the UN/FCCC Kyoto protocol and the air quality targets of the EU were assessed with the help of coupled models. With two alternative energy scenarios reflecting the Kyoto targets for CO2, reductions of sulfur and NOx emissions between 12% and 22% and 8% to 12%, respectively, were estimated by 2010 in the EU-15 with the present emission control legislation. Due to the lower activity levels generating less emissions and the cleaner energy forms used, 35-43% cost savings in further technical emission controls required for achieving the EU air quality targets would be achieved with the scenarios studied. Case studies for Finland indicated that there has been a decrease of 60% in the area at risk of acidification from 1990 to 1995, and that the declining trend is expected to continue due to the recent international emission reduction agreements within the UN/ECE and the EU. Implementation of the Kyoto protocol in Finland and in the whole of EU-15 (with the present emission legislation) could bring up to 8% more reduction of ecosystems at risk of acidification in Finland by 2010 than the recent UN/ECE protocol.An uncertainty analysis of acidification integrated assessment modeling in Finland indicated that critical loads dominate the uncertainty. Estimates are becoming more robust, as the general level of deposition is decreasing. In Finland, further efforts to reduce the overall uncertainty should be mainly directed to more accurate description of critical thresholds. In areas affected by major nearby emission sources, also uncertainties in emissions and deposition are significant. The models and their applications presented in this study contributed to identifying the problem characteristics and have supported environmental policy development at international, national and regional levels.

    Due to the Arctic climate change and the related diminishing of Arctic sea ice cover, the general conditions for Arctic shipping are changing. The retreat of Arctic sea ice opens up new routes for maritime transportation, both trans-Arctic passages and new alternatives within the Arctic region. Hence the amount of Arctic shipping is presumed to increase. Despite the observed development, the sailing conditions in the Arctic waters will remain challenging. Thus particular attention will be required also in the future with regard to crew, fleet and other infrastructural issues. In addition to other apparent challenges and risks, the increase in Arctic shipping will lead to an increased amount of emissions. The increased emissions may have considerable and unpredictable influences to the particularly sensitive Arctic environment. With regard to emission species, especially black carbon is presumed to have climatic sig-nificance within the Arctic context. Black carbon absorbs solar radiation very effectively, and when deposited to snow or sea ice cover, it may notably alter the radiative equilibrium of the Arctic region. The increased Arctic marine activities produce black carbon emissions, whose climate impacts are assessed in this report.
  • Rainio, Jaakko (Helsingin yliopisto, 2020)
    Tässä tutkielmassa tarkastellaan roomalaisen kirjailijan, Gaius Plinius Secunduksen (Plinius vanhempi), kirjoittamaa 37-osaista ensyklopediaa nimeltä Naturalis Historia. Tutkielman materiaalina on käytetty teoksen toista kirjaa, joka käsittelee kosmologiaa ja maailmankaikkeutta, ja sieltä on poimittu runsaasti esimerkkitekstejä. Tekstit käsittelevät maailmaa yleisesti, auringon- ja kuunpimennyksiä, tuulia, maanjäristyksiä, tuliperäisiä alueita, tulia ja niihin liittyviä välillisiä ilmiöitä. Jokaisen luonnonilmiön kohdalla on myös selvitetty, minkälaisia antiikin ajan enteitä ja uskomuksia niihin liittyy. Tutkielman tavoitteena on selvittää Plinius vanhemman käsityksiä maasta, maapallosta, sen muodosta ja sijainnista universumissa. Tavoitteena on myös analysoida, minkälaisina tapahtumina Plinius vanhempi tulkitsee erilaiset luonnonilmiöt ja millä argumenteilla hän kuvailee näiden ilmiöitten syntymistä. Tutkielmassa sivutaan myös käsitteitä “jumaluus” ja “äitimaa”, ja näiden ihmisille tarjoamia hyötyjä ja haittoja. Moraalifilosifan kannalta on otettu mukaan käsitteet avaritia ja luxuria, joiden osalta Plinius arvioi kriittisesti ihmiskuntaa ja sen toimintaa. Pliniukselta valitun tutkimusmateriaalin perusteella on tehty joitain yleistyksiä. Auringon ja kuun toiminnat maapallon eri ilmiöitä ohjaavina voimina on kiistatonta Pliniuksen antamien esimerkkien perusteella. Naturalis Historian kansantajuinen esittämistapansa vähentää luonnonilmiöihin liittyvää taikauskoa, ja syntyvien enteiden tulkinta ei aina pääty siihen, että enteet olisivat pahoja. Käsitteiden avaritia ja luxuria pohdinta luovat terveen moraalisen käsityksen ihmiskunnan omasta toiminnasta luontoäidin ihmisille tarjoamista lahjoista. Plinius tulkitsee maailman koostuvan kahdesta päätekijästä, jotka ovat terra ja caelum. Näihin sisältyvät käsitteet luonto ja jumala. Kyse on näiden keskinäisestä vuorovaikutuksesta ja tasapainosta. Vuorovedet ovat kuun aikaansaamia ilmiöitä, jotka yhdessä auringon ja kuun kanssa luovat maailmaan aikasidonnaisen ja säännöllisen kiertokulun. Käsitys maailmasta suljettuna tilana tulee esiin maanjäristysten ja tuulien kohdalla, mutta Pliniuksen tietämättömyys luonnonilmiöiden todellisista syntymekanismeista on silmiinpistävää. Tuliperäisyyden ja tulet Plinius liittää antiikin ajan uskonnollisen mailman kanssa ja tulkitsee oman aikansa tietämyksen perusteella kyse olevan kyseessä joko jumalan vihan tai ihmisen ahneudellaan luonnolle aiheuttaman epätasapainon.

    Air pollution emissions are produced in a wide variety of sources. They often result in detrimental impacts on both environments and human populations. To assess the emissions and impacts of air pollution, mathematical models have been developed. This study presents results from the application of an air pollution emission model, the Finnish Regional Emission Scenario (FRES) model, that covers the emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), ammonia (NH3), non-methane volatile organic compounds (NMVOCs) and primary particulate matter (TSP, PM10, PM2.5 and PM1) in high 1 ´ 1 km2 spatial resolution over the area of Finland. The aims of the study were to identify key emission sources in Finland at present and in the future, to assess the effects of climate policies on air pollution, and to estimate emission reduction potentials and costs. Uncertainties in emission estimates were analyzed. Finally, emission model characteristics for use in different air pollution impact applications were discussed.The main emission sources in Finland are large industrial and energy production plants for SO2 (64% of 76 Gg a-1 total in the year 2000). Traffic vehicles are the main contributors for NOx (58% of 206 Gg a-1), NMVOCs (54% of 152 Gg a-1) and primary PM2.5 (26% of 31 Gg a-1) emissions. Agriculture is the key source for NH3 (97% of 33 Gg a-1). Other important sources are domestic wood combustion for primary PM2.5 (25%) and NMVOCs (12%), and fugitive dust emissions from traffic and other activities for primary PM10 (30% of 46 Gg a-1).In the future, the emissions of traffic vehicle exhaust will decrease considerably, by 76% (NMVOCs), 74% (primary PM2.5) and 60% (NOx), from 2000 to 2020, because of tightening emission legislations. Rather smaller decrease is anticipated in the emissions of large combustion plants, depending on future primary energy choices. Sources that are not subject to tight emission standards, e.g. domestic combustion and traffic-induced fugitive dust (i.e. non-exhaust), pose a risk for increasing emissions.The majority of measures to abate climate change, e.g. energy saving and non-combustion based energy production, lead to co-benefits as reduced air pollution emissions, especially of SO2 (20% to 28% reduction). However, promotion of domestic wood combustion poses a risk for increase in PM2.5 and NMVOCs emissions. Further emission reductions with feasible control costs are possible mainly for PM2.5 in small energy production plants and domestic combustion sources. Highest emission uncertainties were estimated for primary PM emission factors of domestic wood combustion, traffic non-exhaust sources and small energy production plants.The most important characteristics of emission models are correct location information of flue gas stacks of large plants for the assessment of acidification, and description of small polluters with high spatial resolution when assessing impacts on populations. Especially primary PM2.5 emissions originate to a considerable degree from small low-altitude sources in urban areas, and therefore it is important to be able to assess the impacts that take place near the emission sources. Detailed descriptions of large plants and 1 ´ 1 km2 spatial resolution for small emission sources applied in the FRES model enable its use in the assessment of various national environmental impacts and their reduction possibilities.The main contribution of this work was the development of a unique modeling framework to assess emission scenarios of multiple air pollutants in high sectoral and spatial resolution in Finland. The developed FRES model provides support for Finnish air pollution polices and a tool to assess the co-benefits and trade-offs of climate change strategies on air pollution.

    Julkaisu sisältää tietoa Etelä-Savon ympäristökeskuksen toiminta-alueella (Etelä-Savon maakunta) aiheutuvasta ympäristökuormituksesta. Tiedot on koottu Ympäristöhallinnon ylläpitämästä Valvonta- ja kuormitustietojärjestelmästä (VAHTI), jonne ympäristölupavelvolliset vuosittain ilmoittavat tiedot mm. ilma- ja vesipäästöistä sekä jätemääristä. Raportti keskittyy vuoden 2005 tietoihin, mutta osa tiedoista on aikaisemmilta vuosilta, jos vuoden 2005 tietoja ei ole ollut saatavilla. Raporttiin on koottu tietoa myös aikaisempien vuosien kuormituksesta, jotta voidaan seurata kuormituksen kehittymistä. Ihmisen aiheuttama ympäristökuormitus Etelä-Savossa on erittäin vähäistä verrattuna muuhun Suomeen. Etelä- Savosta puuttuu lähes kokonaan suuret teollisuuslaitokset, jotka ovat suuria piste-kuormittajia. Maakunnan asukasmäärä ja –tiheys ovat pieniä verrattuna keskimäärin muuhun Suomeen, jolloin yhdyskuntien pistekuormittajat (esim. voimalaitokset ja jätevedenpuhdistamot) ovat kooltaan melko pieniä ja kuormitus vähäistä.
