Spatial and temporal variation of ambient carbonaceous aerosol in Ireland and strategies for effective monitoring of source contributions
The concentration, size and composition of atmospheric aerosols determines their impact on health and climate. These parameters are highly variable and inherently linked with source, seasonality and geographical location. In this study, a suite of instruments was deployed to quantitatively investigate the properties of ambient carbonaceous aerosol at six unique locations around Ireland. Source apportionment analysis was performed for the identification of dominant sources contributing to the ambient carbonaceous aerosol in each environment.
This work serves to highlight the spatial and temporal variability of ambient carbonaceous aerosol in Ireland. Aethalometer data exhibited significant spatial variability of black carbon (BC). The lowest concentrations were recorded at regional background sites, while the highest concentrations were recorded in populous, urban settings. The aethalometer source apportionment model was used to demonstrate spatial variability of contributions from dominant sources. The temporal variability of carbonaceous aerosol was explored through data collected during long-term monitoring campaigns in Dublin and Enniscorthy. Strong seasonal variation in equivalent black carbon (eBC) was evident, particularly in locations strongly influenced by solid fuel burning for residential heating. Furthermore, approximately 40% and 72% of total eBC measured during winter at University College Dublin and Enniscorthy, respectively, was attributed to solid fuel combustion. Strong diurnal trends were observed in each location, however the absolute concentration was seasonally dependent. A pronounced evening peak, attributed to solid fuel combustion emissions, was observed at the majority of sampling sites during the winter months. Urban areas also had a morning peak consistent with rush hour and was attributed to the influence of traffic-related emissions.
Novel data collected at several unique environments as part of three individual long-term monitoring campaigns, demonstrated the ubiquitous nature of carbonaceous aerosol, particularly BC, in Ireland and the associated impact on local air quality. Despite the negative implications on human health, air quality and climate, BC is not regulated or routinely monitored in Ireland. This research outlines the potential benefits of establishing an extensive, national BC monitoring network, including the collection of real-time data to inform vital air pollution mitigation policies
Primary and secondary emissions from upland fires in Ireland
Emissions from wildfires have detrimental effects on air quality, climate change and human health. Despite frequent occurrence of wildfires and prescribed agricultural burns in upland areas, data on wildfire emissions in Ireland is scarce. This work was conducted as part of FLARES (Fire, Land and Atmospheric Remote Sensing of EmissionS), a project funded by the Irish Environmental Protection Agency (EPA) to improve the understanding of Irish upland fire emissions. Emission factors (EF) of typical Irish wildfire fuels (heather, gorse, purple moor grass) were measured for the first time. Emission factors were measured for a set of gases (carbon monoxide CO, carbon dioxide CO2, methane CH4, sulphur dioxide SO2 and nitric oxides NOx as NO), particulates and particulate fractions (fine particulate matter PM2.5, total particulate matter TPM, black carbon BC, organic carbon OC, elemental carbon EC and total carbon TC) and molecular biomarkers (levoglucosan, mannosan, galactosan, 4-Nitrocatechol 4-NC, 4-Nitrophenol 4-NP and 4-Nitroguaiacol 4-NG).
Emission factors of measured gases were as follows: CO: 42 g/kg (heather), 27 g/kg (moor grass) and 80 g/kg (gorse); CO2 1167 g/kg (heather), 1558 g/kg (moor grass) and 1442 g/kg (gorse); SO2: 1.38 g/kg (heather), 1.08 g/kg (moor grass) and 1.68 g/kg g/kg (gorse); NOx as NO: 4.46 g/kg (heather), 5.51 g/kg (moor grass), and 6.85 g/kg (moor grass); CH4: 0.21 g/kg (moor grass) and 0.38 g/kg (gorse). Particulate EFs resulted in EF of 4.71 g/kg (heather), 2.42 g/kg (moor grass) and 10.46 g/kg (gorse) for PM2.5; 3.95 g/kg (heather), 4.26 g/kg (moor grass) and 14.33 g/kg (gorse) for TPM; 0.26 g/kg (heather), 0.21 g/kg (moor grass) and 0.50 g/kg (gorse) for BC; 1.28 g/kg (heather), 1.26 g/kg (moor grass) and 5.43 g/kg (gorse) for OC; 0.80 g/kg (heather), 0.81 g/kg (moor grass) and 2.23 g/kg (gorse) for EC; 2.09 g/kg (heather), 2.07 g/kg (moor grass) and 7.65 g/kg g/kg (gorse) for TC. EFs for biomarkers were 0.09 g/kg (heather), 0.18 g/kg (moor grass) and 0.19 g/kg (gorse) for levoglucosan; 0.01 g/kg (heather), 0.01 g/kg (moor grass) and 0.01 g/kg (gorse) for mannosan and 0.01 g/kg (heather), 0.01 g/kg (moor grass) and 0.02 g/kg (gorse) for galactosan; 0.78 mg/kg (heather), 0.42 mg/kg (moor grass) and 1.36 mg/kg (gorse) for 4-NC; 0.05 mg/kg (heather), 0.04 mg/kg (moor grass) and 0.07 mg/kg (gorse) for 4-NP and 0.25 mg/kg (heather), 0.15 mg/kg (moor grass) and 0.34 mg/kg (gorse) for 4-NG. Combustion took place under flaming combustion conditions, reflected in high modified combustion efficiencies (MCE) of 0.95 to 0.98. Emissions for species like CO, PM2.5 and volatile organic compounds (VOCs) would be expected to be higher under real-world conditions where MCE is lower.
Secondary organic aerosol (SOA) formation from combustion emissions of the three fuels was studied under simulated day-time (UV lights and UV+OH precursor addition) and night-time conditions (dark + O3 addition) in an atmospheric simulation chamber. SOA mass increased by 2-11% and was dependent on fuel type and oxidising conditions. Field and laboratory samples were analysed at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig, Germany. Filter samples were analysed for the biomarkers levoglucosan, mannosan, galactosan, 4-nitrocatechol, 4-nitrophenol, and 4-nitroguiacol.
Laboratory experiments were complemented by field studies. Ambient levels of PM2.5 and BC were measured during an 8-week field study in Glencree, rural Co. Wicklow, Ireland. Source appointment of BC and analysis of biomarkers found no unambiguous signals that could be associated with wildfires. However, this dataset represents a valuable glance at air quality in a rural setting in Ireland. Despite the remote location and low population density in Glencree Valley, anthropogenic influences on air quality were significant, most notably from residential solid fuel burning. Monthly PM2.5 concentrations in Glencree (4.6 μg m–3) were lower than in nearby urban Tallaght (7.0 μg m–3), but less than expected based on the difference in population and local pollution sources. Other field observations included opportunistic sampling of the plume of a major wildfire at Killarney National Park, Co. Kerry, in April 2022.
Findings presented in this thesis contribute to the understanding of wildfire emissions in Ireland and highlight the influence of anthropogenic air pollution from solid fuel burning on rural locations
”Ja, denna stig är stigarnas stig” : Taoistiska influenser i Vilhelm Ekelunds verk
Mattias Aronsson, ”Ja, denna stig är stigarnas stig”. Taoistiska influenser i Vilhelm Ekelunds verk (“Yes, this path is the path of paths”. Taoist influence in the works of Vilhelm Ekelund) In this article I show how Taoist philosophy has influenced the Swedish poet, essayist and aphorist Vilhelm Ekelund. I note that the author mentions the Taoist philosophers Lao Tzu and Chuang Tzu and discusses their ideas on a couple of occasions in his later works (Atticism – Humanism, 1943; Plus salis–, 1945). Examples of such explicit influence can also be found in Ekelund’s private notebooks, posthumously published in two volumes: Hemkomst och flykt (1972) and Ur en scholaris’ verkstad (1974). I argue that Taoist philosophy implicitly influenced the Swedish author as early as the second part of the 1910’s – when he started to emphasize such principles as moderation, composure, dispassion and non-desire in his writing. I also discuss other important ideals which Ekelund shared with the Taoist philosophers, such as poverty, humility, simplicity and dishonour. Finally, I see a parallel in the anti-intellectual aspects of Taoist thinking and Ekelund’s use of the term misologi (misology), a word which often has positive connotations in his works. In Ekelund’s prose, as well as in the famous Taoist text Tao Te Ching, excessive intellectualism is frequently criticized

Att framställa det oframställbara. Stig Larssons poesi och det postmoderna
The paper constitutes an analysis of the poetry of Stig
Larsson in the context of the postmodern break-up of traditional
definitions of literary genres. The characteristic features of the
Swedish poet's work are ambiguity, fragmentation, rich intertextual
references, and, most importantly, a radically undefined, diffuse
persona of the speaker, no longer able to organize the presented
world. Larsson's poetry is rich in lexical, semantic and syntactic
experimentation. The poet suggests a change in the relation
between the author and the reader

Stig Dagerman – the existentialist? : - Island of the Doomed in the light of five existentialist thinkers
Is the Swedish author Stig Dagerman an existentialist? This work takes a close look at Dagerman’s novel Island of the Doomed to see if it is possible to consider it an expression of existentialist thinking and to see if it interacts with any specific existentialist tradition. Dagerman’s novel was compared with select works of five existentialist thinkers – Søren Kierkegaard, Martin Heidegger, Jean-Paul Sartre, Albert Camus and Karl Jaspers, all read in the light of the four categories of existentialistic thinking identified by the Swedish scholar Lennart Koskinen. All the four categories appeared to be central themes within the novel and a few subcategories were identified. An analysis based on these subcategories showed that the novel had obvious similarities with all of the five existentialistic thinkers. The main conclusion of my work is thus: it is reasonable to consider Stig Dagerman’s novel Island of the Doomed an expression of existentialist thinking, but it doesn’t match any specific existentialist tradition. Dagerman is therefore to be considered an independent existentialist
