Asteraceae Family

In addition to appearing in crops, weeds may pose a risk to human health, indirectly due to the widespread use of herbicides and directly, because they are source of pollen that in susceptible people can cause allergic reactions. Among the weed species, the main allergens are the species of the botanical family: Asteraceae, Amaranthaceae, Urticaceae, Euphorbiaceae and Plantaginaceae. Asteraceae family includes 1,100 genera and 20,000 species, which is one of the largest flowering plants. However, in our area as a potential allergen the most important is Ambrosia and Artemisia pollen. Sampling of ragweed and mugwort pollen during the pollination period 2012-2017 was conducted in urban part of Banja Luka in PI AIRS, BL with Hirst sampler using the method defined by the International Association for Aerobiology (IAA). The first mugwort pollen grains in 2011 were recorded at the end of May, during 2012 and 2016 in the first decade of June, and from 2013 to 2015, as well in 2017 in the second decade of June. Mugwort pollination period lasted for an average of 55 days and it was characterized by low (1-10 p/m3) to moderate (11-50 p/m3) concentrations. The ragweed period pollination during the seven-year monitoring lasted, on average, about 115 days. High concentrations (51-500 p/m3) were recorded between the second decade of August to the third decade of September, while very high concentrations (501 p/m3) were recorded only in 2011. On an annual basis not only the season of ragweed pollination lasted longer, but the results of the monitoring and comparative analysis showed significantly higher % share of ragweed pollen within the weed species in the family Asteraceae in the city of Banja Luka.

The results of aeropalynological studies in Ivano-Frankivsk during 2013–2015 are presented in this article. The studies were conducted using a specially designed gravimetric Durham pollen trap installed at a height of 24 m from the ground. We determined that pollen grains of the following taxa dominate in the city’s aeropalynological spectrum: <em>Corylus</em>, <em>Alnus</em>, <em>Betula</em>, <em>Populus</em>, <em>Fraxinus</em>, <em>Salix</em>, <em>Carpinus</em>, <em>Quercus</em>, <em>Pinus</em>, <em>Picea</em>, Poaceae, Urticaceae, <em>Artemisia</em>, and <em>Ambrosia</em>. Pollen grains from woody plants dominate the aeropalynological spectrum. The considerable presence of the tree pollen grains in the ambient air is due to the geographical location of Ivano-Frankivsk in the forest-steppe zone of Ukraine. Pollen season of allergenic plants lasts from the second week of February to early October. The most unfavorable period for patients with pollen allergy in Ivano-Frankivsk is April, when there is a simultaneous appearance of high concentrations airborne allergenic pollen of <em>Betula</em>, <em>Fraxinus</em>, and <em>Carpinus</em>. From the second week of May to mid-July, high (&gt;50 pollen grains/m<sup>3</sup>) concentrations of allergenic pollen of the Poaceae family members are detected in the air. In the second half of August and early September, high concentrations of allergenic <em>Ambrosia </em>pollen were recorded in the city air. Conducting of pollen monitoring in the city is extremely necessary for prevention, diagnosis, and treatment of pollen allergy.

RESUMEN. El polen de Eucalyptus y su incidencia en la atmósfera de Vigo (N.O. España). Eucalyptus globulus Labill. es la especie arbórea de la familia Myrtaceae, más frecuente en los alrededores de la ciudad de Vigo formando abundantes y densas masas forestales. Aunque su polen se considera moderadamente alergénico, en áreas en las que, como consecuencia de repoblación forestal ocupa extensiones importantes, puede llegar a causar problemas alérgicos.Entre los años 1995 y 2000 se ha realizado el estudio aerobiológico en la ciudad de Vigo mediante un captador LANZONI VPPS 2000 situado en la margen derecha de la ría de Vigo (42°14'15"N, 8°43'30"W). La cantidad de granos de polen anual de Myrtaceae varía ampliamente, alternándose años de concentraciones bajas con otros de valores elevados que representan entre un I y un 3% del polen total anual. El valor más elevado se detectó en 1997 con 1.147 granos de polen. Se encuentra en la atmósfera de Vigo durante todo el año, aunque las concentraciones más importantes se producen generalmente durante los meses de marzo y abril. Asimismo, a lo largo del día los máximos de concentración tienen lugar entre las 15 y las 17 horas. Finalmente se ha realizado un análisis estadístico para poner de manifiesto la posible correlación existente entre las concentraciones de polen y los principales parámetros meteorológicos. El viento procedente del N-NE fue el parámetro con el que se obtuvo correlación positiva y significativa de forma constante, mientras que esta fue negativa con la humedad relativa.Palabras clave. Meteorología, Myrtaceae, Polen, Eucalyptus, Vigo.ABSTRACT. The Eucalyptus pollea and its incidence in the atmosphere of Vigo (N. W. Spain). Eucalyptus globulus Labill. is the most frequent arboreal species of the Myrtaceac family in the surroundings of the city of Vigo, and it constitues abundant and dense forestal masses. Although its pollen can be considered as a moderated allergen, in areas in which Eucalyptus was used in extended reafforestations, it can cause allergenic problems.From 1995 to 2000 a Hirst-type volumetric sampler (Hirst, 1952), LANZONI VPPS 2000 placed in the left bank of the Vigo estuary (42°14'15"N, 8°43'30"W) was used for collecting airborne pollen. From year to year important oscillations in the annual total pollen was observed, alternating years of high concentrations with other of lower values. Eucalyptus pollen counts represent a percentage that vary between I% to 3% of the total pollen, the high quantity being collected in 1997 with 1,147 pollen grains. The Myrtaceae pollen appears in the atmosphere of Vigo all over the year, although the more important concentrations are registered during March and April. Moreover, maximum daily concentrations occur between 17.00 and 18.00 hours. Finally, a statistical analysis has been carried out in order to search for the possible correlations between pollen concentration and the main meteorological parameters. The N-NE wind and relative humidity were the parameters that show the highest correlation coefficients, positive and negative respectively.Key words. Meteorology, Myrtaceae, Pollen, Eucalyptus, Vigo.

This article analyzes how the Poles and Jews who disappeared from the western Ukrainian city of L'viv as a result of the Second World War are remembered in the city today. It examines a range of commemorative practices, from monuments and museums to themed cafes and literature, and analyzes how these practices interact to produce competing mnemonic narratives. In this respect, the article argues for an understanding of the city as a complex text consisting of a diverse range of mutually interdependent mnemonic media produced by a range of actors. The article focuses in particular on the ways in which Ukrainian nationalist narratives interact with the memory of the city's “lost others.” The article also seeks to understand L'viv‘s memory culture through comparison with a range of Polish cities that have faced similar problems with commemorating vanished communities, but have witnessed a deeper recognition of these communities than has been the case in L'viv. The article proposes reasons for the divergences between the memory cultures of L'viv and that found in Polish cities, and attempts to outline the gradual processes by which L'viv‘s Polish and Jewish pasts might become more widely integrated into the city's memory culture.

Thunderstorm Outflow

BACKGROUNDA study was undertaken to assess the importance of thunderstorms as a cause of epidemics of asthma exacerbations and to investigate the underlying mechanism.METHODSA case control study was performed in six towns in south eastern Australia. Epidemic case days (n = 48) and a random sample of control days (n = 191) were identified by reference to the difference between the observed and expected number of emergency department attendances for asthma. The occurrence of thunderstorms, their associated outflows and cold fronts were ascertained, blind to case status, for each of these days. In addition, the relation of hourly pollen counts to automatic weather station data was examined in detail for the period around one severe epidemic of asthma exacerbations. The main outcome measure was the number of epidemics of asthma exacerbations.RESULTSThunderstorm outflows were detected on 33% of epidemic days and only 3% of control days (odds ratio 15.0, 95% confidence interval 6.0 to 37.6). The association was strongest in late spring and summer. Detailed examination of one severe epidemic showed that its onset coincided with the arrival of the thunderstorm outflow and a 4–12 fold increase in the ambient concentration of grass pollen grains.CONCLUSIONSThese findings are consistent with the hypothesis that some epidemics of exacerbations of asthma are caused by high concentrations of allergenic particles produced by an outflow of colder air, associated with the downdraught from a thunderstorm, sweeping up pollen grains and particles and then concentrating them in a shallow band of air at ground level. This is a common cause of exacerbations of asthma during the pollen season.

Introduction. Biometeorological circumstances have a big influence on all traffic participants, especially reflexes, moving coordination and perception ability. With a lower attention and drivers? and pedestrians? concentration, there was a larger amount of pedestrian trauma in certain biometeorological phases. Objective. The aim of this study was to establish the correlation between pedestrian trauma and biometeorological phases. Methods. The comparative analysis of everyday biometeorological phases for the city of Kragujevac determined by RHMI and the evidence of knocked-down pedestrians from the Kragujevac traffic police for the period 2003-2008. Results. There were 6,127 accidents, with 696 knocked pedestrians in 666 (10.87%) accidents. Most of them happened in 2003 (135), and the fewest in 2005 (90). Most accidents were during December (74), the fewest were in June (46). The fewest accidents were during 04-05-06 hour interval (by 2), most during 13-14 hours (61). There were 374 males and 349 females. Most of the males (by 60) were 0-10 and 11-20 years old, most of the females (74) were 11-20 years old. There were 443 pedestrians who suffered slight body injuries (112 were 11-20), 225 suffered heavy and 28 had lethal injuries (most over 70). As provokers, the pedestrians suffered because of improper crossing roads (185), while as a casualties, they suffered due to speeding of vechicles (285). Most accidents happened in biometeorological phases 4 (168) and 9 (151), the fewest in phase 10 (4). Conclussion. Statistical analysis shows a significant correlation between pedestrians? accidents and biometeorological phases, when the most accidents occurred during penetrations of cold fronts, while there was a sudden switch of weather conditions from warm-dry to cold-wet weather.

Urban water bodies are an important asset in terms of climate change. The accompanying vegetation is an integral part of the waterside space system and a source of ecosystem services and disservices. The composition of greenery in waterside spaces should therefore be preceded by detailed research. This research would be the basis for the development of recommendations for enhancement of the positive impact of vegetation on humans and minimisation of its negative effect. The aim of the study was to identify ecosystem services and disservices of vegetation in the four most important waterside recreation spaces in the city of Rzeszów, Poland, and to develop plant composition guidelines. A detailed inventory of vegetation and aerobiological monitoring of the presence of airborne allergenic pollen grains and fungal spores were carried out. Next, the ecosystem services and disservices of the vegetation were determined based on literature data and on our expert judgement. Additionally, a counting of the number of visitors to waterside areas was conducted. All these steps were used to develop recommendations for shaping the vegetation of study areas. The results of the investigations show that the boulevards along the artificial lake function completely differently than other investigated places as the area resembles an urban park, and the water is not the main attraction in this space. The vegetation of the boulevards and the nearby gravel-pit bathing area has mostly a spontaneous character and offers the widest range of ecosystem services and disservices. The management of the vegetation should focus on its health-enhancing values. The vegetation growing near the outdoor swimming pools has been designed by man. Nevertheless, it requires recomposing and is targeted specifically at the enhancement of the visual attractiveness. Additionally, there is a need for planting compact deciduous trees that will provide shade at the multi-media fountain.
