Influence of Meteorological Parameters on olea pollen concentrations in Córdoba (South-western Spain)
International Journal of Biometeorology, 2003Co-Authors: L. M. Vázquez, C. Galán, E. Domínguez-vilchesAbstract:The influence of Meteorological Parameters on the dispersion of airborne pollen has been studied by several authors. Olive pollen is the major cause of allergy in southern Spain, where a large part of the arable surface area is given over to olive cultivation. Daily pollen forecasts provide important information both for pollen-allergy sufferers and for agronomists trying to achieve a better biological understanding of variations in airborne olive pollen levels. The main purpose of this paper is to study, by means of short-term statistical analysis, the effect of Meteorological Parameters on airborne olive pollen concentrations in the city of Cordoba (south-western Spain). Twenty-one-year (1982–2002) aerobiological and Meteorological databases were used. Correlation and multiple regression analyses were used to study the relationships between olive pollen levels and several Meteorological Parameters. Statistical analysis was applied both to the whole pollen season and to the pre-peak period. Daily Meteorological Parameters, such as accumulated mean temperature, accumulated sunlight hours, and accumulated rainfall were used as independent variables in both statistical analyses. Accumulated Meteorological variables were of the greatest value in most regression analysis equations, heat-related variables being the most important.

Pollution by Urticaceae pollen-influence of selected air pollutants and Meteorological Parameters.
Environmental Science and Pollution Research, 2016Co-Authors: Nataša Čamprag Sabo, Peđa Janaćković, Dragana Đorđević, Aleksandar PopovićAbstract:The goal of this study was to analyze the influence of pollutants (concentrations of NO2, SO2, and soot in the air) and Meteorological Parameters (air temperature, humidity, wind speed, air pressure, cloud index) on Urticaceae pollen type emission measured in the region of Subotica, Serbia. The concentrations of the air pollutants, Urticaceae pollen, and Meteorological Parameters were measured over a 5-year period (2009–2013), followed by a statistical analysis of the values obtained. For most of the years examined, the concentration of NO2 correlates significantly with the concentration of Urticaceae pollen type. It was also established that air temperature, humidity, wind speed, atmospheric pressure, and cloud index have an influence on Urticaceae pollen type emission, while SO2 and soot do not contribute.

Air Pollution by Pollen Grains of Anemophilous Species: Influence of Chemical and Meteorological Parameters
Water Air & Soil Pollution, 2015Co-Authors: Nataša Čamprag Sabo, Aleksandar Popović, Dragana ĐorđevićAbstract:One of the most important particles of biological origin present in the air is pollen grains of plants. Having basic biological function in the process of pollination, pollen grains of some plant species can cause allergic reactions among 20–30 % of the human population and thus affect their health and overall quality of life. Bearing in mind the potential influence air pollutants and Meteorological Parameters may have on release of pollen and granules of allergen from pollen, concentrations of air pollutants and 26 different anemophilous aeropollen types as well as Meteorological Parameters were established in a 5-year period (2009–2013) in Subotica, Northern Serbia. Spearman’s rank correlation was made for statistical analysis of relationships between concentration of some air pollutants (sulphur dioxide, nitrogen dioxide, soot, particulate matter (PM)_10 and PM_2.5), Meteorological factors (temperature of air, humidity, wind speed, cloud index) and airborne pollen. In most of the examined years, significant positive correlations were determined between temperature and total pollen concentration, while significant negative correlations were established between humidity as well as cloud index and total pollen concentration, clearly proving the influence these Meteorological Parameters have on pollination of all examined species.

Fifteen years' record of airborne allergenic pollen and Meteorological Parameters in Thessaloniki, Greece
International Journal of Biometeorology, 2004Co-Authors: Dimitrios Gioulekas, Christos Balafoutis, Athanasios Damialis, Despoina Papakosta, George Gioulekas, Dimitrios PatakasAbstract:A pollen calendar has been constructed for the area of Thessaloniki and relationships between pollen transport and Meteorological Parameters have been assessed. Daily airborne pollen records were collected over a 15-year period (1987–2001), using a Burkard continuous volumetric pollen trap, located in the centre of the city. Sixteen allergenic pollen types were identified. Simultaneously, daily records of five main Meteorological Parameters (mean air temperature, relative humidity, rainfall, sunshine, wind speed) were made, and then correlated with fluctuations of the airborne pollen concentrations. For the first time in Greece, a pollen calendar has been constructed for 16 pollen types, from which it appears that 24.9% of the total pollen recorded belong to Cupressaceae, 20.8% to Quercus spp., 13.6% to Urticaceae, 9.1% to Oleaceae, 8.9% to Pinaceae, 6.3% to Poaceae, 5.4% to Platanaceae, 3.0% to Corylus spp., 2.5% to Chenopodiaceae and 1.4% to Populus spp. The percentages of Betula spp., Asteraceae ( Artemisia spp. and Ambrosia spp.), Salix spp., Ulmaceae and Alnus spp. were each lower than 1%. A positive correlation between pollen transport and both mean temperature and sunshine was observed, whereas usually no correlation was found between pollen and relative humidity or rainfall. Finally, wind speed was generally found to have a significant positive correlation with the concentrations of 8 pollen types. For the first time in the area of Thessaloniki, and more generally in Greece, 15-year allergenic pollen records have been collected and Meteorological Parameters have been recorded. The airborne pollen concentration is strongly influenced by mean air temperature and sunshine duration. The highest concentrations of pollen grains are observed during spring (May).
