“…These are ragweed with mugwort leaves (= short ragweed; Ambrosia artemisiifolia = Ambrosia elatior), giant ragweed (Ambrosia trifida), perennial ragweed (Ambrosia psilostachya) and silver ragweed (Ambrosia tenuifolia). However, short ragweed is the most widely spread of all, not only in Western Europe but in Hungary too (Jµrai-Komlódi and Juhµsz 1993).…”

Meteorological variables connected with airborne ragweed pollen in Southern Hungary

About 30% of the Hungarian population has some type of allergy, 65% of them have pollen sensitivity, and at least 60% of this pollen sensitivity is caused by ragweed. The short (or common) ragweed (Ambrosia artemisiifolia = Ambrosia elatior) has the most aggressive pollen of all. Clinical investigations prove that its allergenic pollen is the main reason for the most massive, most serious and most long-lasting pollinosis. The air in the Carpathian Basin is the most polluted with ragweed pollen in Europe. The aim of the study is to analyse how ragweed pollen concentration is influenced by meteorological elements in a medium-sized city, Szeged, Southern Hungary. The data basis consists of daily ragweed pollen counts and averages of 11 meteorological parameters for the 5-year daily data set, between 1997 and 2001. The study considers some of the ragweed pollen characteristics for Szeged. Application of the Makra test indicates the same period for the highest pollen concentration as that established by the main pollination period. After performing factor analysis for the daily ragweed pollen counts and the 11 meteorological variables examined, four factors were retained that explain 84.4% of the total variance of the original 12 variables. Assessment of the daily pollen number was performed by multiple regression analysis and results based on deseasonalised and original data were compared.

“…It has been also shown that there is a cross reactivity of Betula pollen with Corylus and Alnus pollen, as well as with apple, hazelnut and peach (Lazaro et al, 1999;Son et al, 1999) In previous years there have been few studies that deal with aeroallergen pollen in South Panonian valley (Ja´rai-Komlo´di and Juha´sz, 1993;Kadocsa et al, 1993;Juha´sz, 1997, 2002). However, there have been no studies of airborne Betula pollen, conducted in the State Union of Serbia and Montenegro.…”

Pollen of Betula spp. is one of the main European aeroallergens. The aim of this study was to determine characteristics and occurrence of the Betula pollen in Novi Sad atmosphere, based on 3-year observations (2000)(2001)(2002), and to compare pollen season start dates calculated by different methods. Pollen samples have been collected by Hirst volumetric method with a 7-day Burkard spore trap. Four methods (Sum 75, 2.5%, 30 and 1 pg/m 3 ) have been used for determination of the start dates of the Betula pollen season and the results have been compared. The total annual pollen sum increased during the observed period. In 2000, the highest daily pollen concentrations were 97, 137 and 1034 pg/m 3 , respectively. The earliest Betula pollen season start has been calculated by the 1 pg/m 3 method.

“…The plain is bordered by the Carpathian Mountains, the Alps, the Dinaric Alps and the Balkan mountains. Recent phytogeographical studies that analysed the distribution and abundance of ragweed populations and aerobiological studies that examined the characteristics of airborne ragweed pollen have shown that countries with territory in the region of the Pannonian Plain, primarily Hungary (Jarai- Komlodi and Juhasz 1993;Járai-Komlódi 2000;Vitányi et al 2003;Juhász et al 2004;Apatini et al 2008), but also parts of Austria (Jäger 2000), Bosnia and Herzegovina (Janjić et al 2007), Croatia (Juhász et al 2004;Peternel et al 2005), Czech Republic (Rybnícek et al 2000), Romania (Juhász et al 2004), Serbia (Juhász et al 2004;Šikoparija et al 2006;Janjić et al 2007), Slovakia (Makovcová et al 1998;Bartková-Scevková 2003), Slovenia (Seliger 1998;Juhász et al 2004) and Ukraine (Mosyakin and Yavorska 2002), could be considered as severely infected by ragweed plants and threatened by ragweed airborne pollen.…”

The Pannonian plain as a source of Ambrosia pollen in the Balkans

et al. 2009

This study aims to find likely sources of Ambrosia pollen recorded during 2007 at five pollen-monitoring sites in central Europe: Novi Sad, Ruma, Negotin and Nis (Serbia) and Skopje (Macedonia). Ambrosia plants start flowering early in the morning and so Ambrosia pollen grains recorded during the day are likely to be from a local source. Conversely, Ambrosia pollen grains recorded at night or very early in the morning may have arrived via long-range transport. Ambrosia pollen counts were analysed in an attempt to find possible sources of the pollen and to identify Ambrosia pollen episodes suitable for further investigation using back-trajectory analysis. Diurnal variations and the magnitude of Ambrosia pollen counts during the 2007 Ambrosia pollen season showed that Novi Sad and Ruma (Pannonian Plain) and to a lesser degree Negotin (Balkans) were located near to sources of Ambrosia pollen. Mean bi-hourly Ambrosia pollen concentrations peaked during the middle of the day, and concentrations at these sites were notably higher than at Nis and Skopje. Three episodes were selected for further analysis using back-trajectory analysis. Back-trajectories showed that air masses brought Ambrosia pollen from the north to Nis and, on one occasion, to Skopje (Balkans) during the night and early morning after passing to the east of Novi Sad and Ruma during the previous day. The results of this study identified the southern part of the Pannonian Plain around Novi Sad and Ruma as being a potential source region for Ambrosia pollen recorded at Nis and Skopje in the Balkans.
