A qualitative and quantitative evaluation of pollen concentration in the atmosphere of Izmir metropolitan area is presented. Investigations were undertaken from November 1998 to October 1999 using gravimetric method. The aeroplynological studies revealed that at lower level (1.60 m) pollen from 29 woody and 30 herbaceous taxa were determined, whereas at(More)
Airborne pollen distribution in the city of Nicosia (Cyprus) was measured volumetrically during two consecutive years 2007-2008 on weekly basis using Lanzoni trap (Lanzoni VPPS 2000). A total of 7,880 pollen grains/m(3) belonging to 44 taxa, in 2007 were 3,593 pollen grains/m(3) and in 2008 it was 4,287 pollen grains/m(3), were determined. Out of these, 25(More)
The chemical composition and the antimicrobial activity of the essential oils isolated from the leaves (LEO) and flowers (FEO) of Anthemis xylopoda, an endemic taxon of Turkey, were investigated. Borneol was the major constituent of both the oils studied (30.15 and 31.85%, respectively). The antimicrobial activities of both oils were separately evaluated(More)
The antibacterial activity of honey samples from different sources were collected and investigated against Bacillus cereus, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae ATCC 27736, Morganella morganii, Micrococcus luteus NRRL B-4375, Escherichia coli ATCC 35218, and Candida albicans. Pathogens exhibited(More)
In this present study, airborne pollen in Çeşme was investigated between February 17, 2012 and February 17, 2014 using the volumetric method. Çeşme, one of Turkey's most important tourism centers, which attracts numerous local and foreign tourists each year, is a district of Izmir, a province in the western part of Turkey. During the 2-year study, 12,905(More)
This study aims to investigate the differences in the concentrations of airborne fungi and pollens between the towns located in the province of Izmir and to determine the factors contributing to these differences. Five stations in each of four towns (Buca, Konak, Bornova, and Karsiyaka) were randomly selected as the research areas. Fungus (cfu/m(3)) and(More)
