Abstract

<p>Background:Airborne pollen was examined in Ito City, Shizuoka for the purpose of treatment and prophylaxis pollen allergies because the patients with pollen allergy to herbaceous plants have recently increased.</p><p>Methods: Setting up a Durham’s sampler, we measured airborne pollen identified and classified: Poaceae, Polygonaceae, Amaranthaceae, Urticaceae, Cannabaceae, Ambrosia and Artemisia indica.</p><p>We studied whether each airborne pollen count has something to do with weather condition (2004-2015).</p><p>Results: Average total airborne Poaceae pollen count and standard deviation from January to June was 19.4±5.5 cells/cm2, average total airborne Polygonaceae pollen count and standard deviation from April to September was 11.6±13.4 cells/cm2. Airborne Poaceae, Amaranthaceae, Cannabaceae, Uriticaceae. Ambrosia and Artamisia indica pollen count from July to Deccember in order: 34.0±15.5 cells/cm2, 1.3±1.1 cells/cm2, 8.7±6.4cells/cm2, 4.9±6.4 cells/cm2, 10.5±7.8 cells/cm2, and 13.6±16.3 cells/cm2.</p><p>Cannabaceae admitted that its airborne pollen count has negative correlation to the rainfall.</p><p>Artemisia indica admitted that its airborne pollen count has negative correlation to the average temperature.</p><p>Conclusion: Herbaceous plants pollen doesn’t cause allergies because it is much less than tree pollen in ItoCity.</p><p>It is thought that the diversity of the plants keep the people from having a serious allergy to pollen with awarm weather in this area.</p>
