The concentration of fungal spores in the air is traditionally considered as a proxy of allergen exposure. However, in vitro experiments have shown that the allergenicity of Alternaria spores varies depending on ecophysiological and developmental factors. Despite the potential clinical significance of these findings, it has never been verified in outdoor environments. This study, therefore, aims to investigate variability in the amount of the major allergen (Alt a 1) released from Alternaria spores in outdoor air. During the 3-year monitoring study (2014-2016), the median seasonal allergenicity of Alternaria spores exceeded 8.6 × 10-3 pg Alt a 1/spore. The most allergenic spores were collected during the driest and the most polluted season (with respect to seasonal concentrations of ozone, sulphur dioxide, and particulate matter). Within the season, daily spore allergenicity ranged from 2.4 to 34.7 × 10-3 pg Alt a 1/spore (5th-95th percentile). No repeatable effects of weather and pollution on short-term variations in Alternaria spore allergenicity were found. However, during the episodes when high-potency spores were recorded, the air masses arrived from eastern directions. Contrary, the spores with the lowest allergenicity were related to western winds. This suggests that factors such as source area (habitat types) and species diversity could be responsible for the varying exposure to Alternaria allergens. Our findings show that high and low-potency spores are recorded in the air; therefore, the airborne concentrations of fungal spores alone may not be sufficient to provide allergy sufferers and healthcare professionals with information about allergen exposure.
The aim of this paper is to investigate public fi nance sustainability for a selected group of ten Central and Eastern European countries. In order to assess the fi scal sustainability of these countries we extend standard analyses typically used for developed countries to our group of ten CEE countries. To assess fi scal sustainability we use panel stationarity and cointegration tests, as well as estimates of certain parameters of fi scal reaction functions. Our research shows that despite the fi nancial turmoil, CEE countries demonstrate the existence of a long-term relationship between revenues and expenditures and they have statistically relevant parameters of the fi scal reaction function. This indicates that the public fi nances in CEE countries are sustainable despite the crisis. However, the analysed group of countries shows sustainability only in a weak sense, which may pose a threat to public fi nances in the future.
The paper analyzes selected indicators monitoring the socioeconomic conditions of the European Union with regard to reducing inequalities. The main attention is paid to the 2030 Agenda and its Sustainable Development Goal 10, which calls for reducing inequalities within and among countries. The empirical part of the study is based on two separate studies and the data source is Eurostat. The first study focuses on the dynamics of the SDG10 indicators for the EU27. Due to the limited availability of all SDG10 indicators, the timeframe of this study covers the years 2010–2019. As a result, the SDG10 indicators for the EU27 as a whole are analyzed over that period or via a comparison of disparities between the two extreme dates, i.e., between 2010 and 2019. The second study focuses on the analysis of (dis)similarities of 27 individual European Union member states with respect to a set of variables capturing the socioeconomic conditions of these countries. The method used is cluster analysis, supported by the linear ordering method and principal component analysis. Due to the limited availability of indicators measuring the progress towards SDG10, especially those related to the evaluation of a citizenship gap, the second research does not use all indicators directly assigned to SDG10 (because most of them are not available for all countries), but rather employs a set of additional variables that may potentially affect the levels and dynamics of inequalities among and within countries. The general conclusion of the study is that the analysis of SDG10 indicators over the medium term (i.e., over the period 2010–2019) implies that the EU27 was able to make progress in reducing inequalities among countries; however, the income inequalities within countries persist or have even deepened. The insights from multivariate statistical methods emphasize the existing disparities between a group of countries, including Spain, Bulgaria, and Romania, and the rest of the EU countries in both analyzed years (i.e., in 2010 and 2019), regardless of the set of variables applied in analyses. Moreover, the results highlight the persistence in disparities between “old” and “new” member states and suggest the disparity between the “peripheral” and the rest of the “old” EU countries. Furthermore, the role of expenditure on social protection in affecting income disparities is emphasized, as is the impact of demographic factors in emphasizing the differences in socioeconomic situations across EU member states.
Temperature is the environmental factor that systematically changes for decades and, as in plants and animals, can significantly affect the growth and development of fungi, including the abundance of their sporulation. During the time of study (2010–2012), a rapid increase in air temperature was observed in Poland, which coincided with the substantial decrease in rainfall. The increase in annual mean temperatures at three monitoring sites of this study was 0.9 °C in Lublin and Rzeszow (east Poland) and 2.0 °C in Poznan (west Poland). Such warming of air masses was comparable to the average global air temperature rise in the period of 1880–2012 accounting for 0.85 °C, as reported by the Intergovernmental Panel on Climate Change. Moreover, there was a substantial decrease in rainfall, ranging from 32.7 % (Poznan) to 43.0 % (Rzeszow). We have demonstrated that under such conditions the mean and median values of total Cladosporium spore counts significantly increased and the spore seasons were greatly accelerated. Moreover, earlier start and later end of the season caused its extension, lasting from over 20 days in Rzeszow to around 60 days in Lublin and Poznan, when the cumulative amount of 5–95 % of spores was considered. The time of reaching the cumulative amount of 50 % of spores was up to 25 days earlier (difference in Poznan between 2010 and 2012). There was also a striking acceleration of the date of the maximal Cladosporium spore concentration per cubic metre of air (26 days for Lublin, 43 for Poznan and 56 for Rzeszow).
