Abstract:
OBJECTIVE To determine the species,quantity,and dispersion patterns of airborne pollen in two districts and five counties of Handan City,Hebei Province.METHODS The gravity sedimentation method was employed from October 1,2023,to September 30,2024,for daily and consecutive pollen exposure slides in two districts(Congtai District and Yongnian District)and five counties(Qiu County,Daming County,Cheng'an County,Cixian County,and She County)of Handan City,Hebei Province.The types of pollen were counted and identified under an optical microscope,and the pollen data were statistically analyzed.RESULTS The annual pollen quantity in the two districts and five counties of Handan City ranged from 24 031 grains/1 000 mm2 to 85 131 grains/1 000 mm2.The dissemination of major allergenic pollen presented two peaks.The first peak occurred in spring(March to April),mainly composed of Platanus(25.15％),Broussonetia(13.61％),Pinus(8.48％);the second peak occurred in(August to September),mainly consisting of Humulus/Cannabis(13.71％)and Artemisia(8.44％).Pollen in spring was significantly higher than that in summer and autumn.CONCLUSION The major allergenic airborne pollen in the two districts and five counties of Handan City exhibited two peaks in spring and summer-autumn,with Platanus pollen,Broussonetia pollen,Pinus pollen,Humulus/Cannabis pollen,and Artemisia pollne being the dominant pollen types.Among them,Platanus pollen was the absolute dominant pollen in this region.
