Abstract

Ovaj rad temelji se na aeropalinološkim istraživanjima tijekom vegetacijske sezone
2017. godine. Cilj rada bio je analizirati: koncentracije peludi ambrozije u zraku, dinamiku
peludne sezone, povezanost između koncentracija peludi ambrozije i meteoroloških
parametara (temperature i oborina) i komparirati rezultata s rezultatima iz prethodnih sezona
(2010.-2016.). Za uzorkovanje je korišten sedmodnevni volumetrijski uzorkivač tipa Hirst,
postavljen na krovu Nastavnog zavoda za javno zdravstvo ˝Dr. Andrija Štampar˝. Uzorci su
pregledani pod svjetlosnim mikroskopom pri povećanju od 400x. Visoke koncentracije peludi
ambrozije zabilježene su tijekom kolovoza i rujna 2017. Najviša koncentracija peludi u zraku
zabilježena je 28. rujna, 180 peludnih zrnaca / m3. Glavna peludna sezona ambrozije u 2017.
godini trajala je od 8. kolovoza do 26. rujna (50 dana). Odnos između koncentracije peludnih
zrnaca i meteoroloških parametara analiziran je pomoću Spearman-ovog testa korelacije.
Utvrđeno je da koncentracije peludi rastu tijekom suhih i toplih dana, a smanjuju se s
pojavom oborina i nižih temperatura. U usporedbi s prethodnim peludnim sezonama
ambrozije (2010.-2016.), glavna peludna sezona 2017. godine je jedna od dužih (50 dana, dok
prosjek iznosi 43 dana), ali je godišnji peludni indeks (2513 peludnih zrnaca / m3) niži od
prosjeka prethodnih sezona (2899 peludnih zrnaca / m3 za razdoblje od 2010.-2016. godine).

Abstract (english)

This thesis is based on aeropalinological research during the 2017 vegetation season.
The aim was to analyse: concentrations of airborne ragweed pollen in Zagreb, seasonal pollen
dynamics, correlation between meteorological parameters (temperature and precipitation) and
pollen concentrations, and to compare results with those from previous pollen seasons (2010-
2016). To collect samples, a seven-day Hirst volumetric trap installed on the roof of ˝Dr
Andrija Stampar˝ Teaching Institute of Public Health was used. Samples were analysed under
the light microscope (magnification 400x). High concentrations of ragweed pollen were
detected in August and September of 2017. The peak of the airborne pollen appeared on
August 28th, 180 pollen grains / m3. In 2017 the main pollen season lasted from August 8th to
September 26th (50 days). The correlation between pollen concentrations and meteorological
parameters were tested using Spearman's correlation test. Pollen concentrations during warm,
dry periods and decreased with the emergence of precipitation and lower temperatures.
Compared to earlier seasons (2010-2016), the main pollen season during 2017 was very long
(50 days, while the average was 43 days), but its annual pollen index (2513 pollen grains / m3)
was lower than average (2899 pollen grains / m3 for the 2010-2016 time period).
