Sažetak
Some pollen grains are known to cause allergic diseases in human beings such as allergic asthma and hay fever. These diseases appear especially in flowering periods of plants. Determination of the type and concentration of pollen grains is beneficial to patients suffering from allergic diseases. Ragweed pollen is the most frequently associated with agriculture and is found in cultivated fields. It also occurs on disturbed soils, wasteland and roadsides along the railways, irrigation canals, on riverbanks and in building yards. Atmospheric birch pollen is of special aerobiological interest in Northern and Central Europe as one of the most common causes of spring-time pollen allergy. The aim of the study is to present the results of airborne ragweed and birch pollen grains carried out from January 2009 to October 2010 using continuous volumetric sampling of airborne pollen in Zagreb atmosphere. The standardized aerobiological volumetric method of airborne pollen sampling by the use of Hirst sampler was used. During monitoring period, 7582 pollen grains of ragweed, equal to 9% of overall pollen spectrum and 16819 grains of birch equal to 19% were measured. Concentrations of ragweed pollen during monitoring period were very similar, while concentrations of birch pollen rise four times since 2009. Total annual concentration of ragweed pollen measured in 2009 was 3844 and in 2010 annual concentration was 3738. Overall concentration of birch pollen measured in 2009 was 3819, while in 2010 measured concentration was 13000 grains. In 2009 concentration of ragweed pollen exceeded the value of over 100 grains during 15 days of monitoring. In 2010 those same values were measured in period of 14 days. More detailed measurements in monitoring period were made for birch pollen. In 2009 concentration values over 100 grains were present during 9 days, while in 2010 those values were present during 18 days. Interesting fact is that concentration of birch pollen in 2010 was above 1000 pollen grains during 5 days, while above mentioned value was measured in only one day during 2009. According to these results we can conclude that the levels of highly allergic pollen of ragweed and birch can be considered as a problem for public health in Zagreb and therefore require further and constant monitoring.
