Airborne pollen

This article describes in detail an advanced statistical method, the artificial neural network, and the possibilities for its application in aerobiological analyses. The study and models involve the concentration of fungal spores in the air and their relationship with various biological and environmental factors. The author hopes that this work will contribute to a wider use of this method not only in the study of spores but also the concentration of pollen grains.

Airborne pollen grains in Aydın, an important city for agriculture and tourism in the western part of Turkey, were studied for 2 years (2014 and 2015) using the volumetric method. During a 2-year study conducted in the city center, an average of 19,226 pollen grains belonging to 46 taxa were detected. Among these detected taxa, 29 (average 73.97%) belonged to arboreal plants and 17 (average 24.95%) to nonarboreal plants. The highest pollen concentrations belonged to Olea europaea (21.02%), Quercus (15.23%), Poaceae (11.89%), Pinaceae (11.47%), Cupressaceae/Taxaceae (11.11%), Platanus(4.

Air pollution induces abnormality in anthers, reduction of pollen grains’ umbers and male sterility. Anthers of Spartium junceum L. (Spanish broom) were collected at different stages of development from control (less polluted) and polluted areas (mainly SO2, NO2, CO, hydrocarbons (HCs) and airborne particulate material (APM)). Structure and development of anther walls and pollen grains were studied and compared.

Phenolic compounds function as stress indicators because they accumulate to high levels in many plant tissues in response to a wide range of biotic and abiotic signals. These compounds are involved in pollen development, pollination, pollen germination, and pollen tube growth.

Airborne pollen in Uşak, a province in Turkey, was studied for two years (from 1 February 2014 to 31 January 2016) using the volumetric method and the most recent pollen data of the region were obtained. During the study, 23,915 pollen grains were detected. The pollens detected belonged to 53 taxa.

Knowledge of the types of atmospheric pollen and their concentrations in a particular area is critical for evaluating air quality and allergen exposure. This study was carried out to determine the pollen diversity and daily, monthly, and annual concentrations in Gümüşhane, whose relationships were then sought with the meteorological factors in the atmosphere of Gümüşhane.
