Aerobiology, epidemiology and disease forecasting of false smut disease of rice in West Bengal, India Aerobiologia (IF 2.708) Pub Date : 2020-02-27 Mouli Saha; Arindom Chakraborty; Kashinath Bhattacharya
In India, since 2001, false smut disease of rice has been observed in severe form among major rice growing states. This disease is difficult to tackle, because pathogens infect the plant during flowering stage, and the symptoms are only visible after emergence of the panicle. Thus, disease forecasting is necessary to predict the chance of disease in a certain set of conditions. We analysed 3 years

Association between Japanese cedar and cypress pollen counts and climate factors over a 10-year period in Tsu city, Japan Aerobiologia (IF 2.708) Pub Date : 2020-02-27 Said Ahmad Shah; Kazuhiko Takeuchi
Japanese cedar pollen and cypress pollen are the most common causes of seasonal allergic rhinitis in Japan. In the present study, we examined the relationship between climate factors and Japanese cedar and cypress pollen counts in Tsu city, Mie prefecture, Japan. Cedar and cypress pollen measurements were taken between 2009 and 2018 using a gravitational method (Durham’s sampler). Each year, during

Daily, seasonal, and interannual variability of airborne pollen of Araucaria angustifolia growing in the subtropical area of Argentina Aerobiologia (IF 2.708) Pub Date : 2020-02-13 Fabiana Latorre; Cristian Rotundo; María Laura Abud Sierra; Hugo Fassola
Araucaria angustifolia is an anemophilous conifer native to Southern America threatened with extinction, with a noticeable decrease in its distribution area and seed production. To better understand the reproductive dynamics, the aerobiological curves obtained with Hirst methodology were analyzed during 7 years in San Antonio (Misiones, Argentina), including productivity, seasonality, start, end, duration

The influence of atmospheric circulation conditions on Betula and Alnus pollen concentrations in Wrocław, Poland Aerobiologia (IF 2.708) Pub Date : 2020-02-12 Hanna Ojrzyńska; Daria Bilińska; Małgorzata Werner; Maciej Kryza; Małgorzata Malkiewicz
The influence of atmospheric circulation conditions on pollen concentrations of two taxons (Betula and Alnus) in Wroclaw, Poland, for the years 2005–2014 was analysed. Pollen concentration was analysed separately for twenty circulation types that were determined using objective classification. The results indicate the atmospheric circulation conditions favourable for both low and high pollen concentrations

Evaluation of microbiological quality of atmospheric air in a selected sewage treatment plant in Lesser Poland Aerobiologia (IF 2.708) Pub Date : 2020-01-24 Iwona Paśmionka
The adverse impact of sewage treatment plants on the environment, resulting from the emission of harmful biological agents to the atmosphere, depends mainly on the size of the facility, the quantity and composition of treated sewage as well as the technologies and equipment used. The aim of the conducted research was to determine the microbiological quality of atmospheric air at Municipal-Industrial

Indoor exposure to airborne bacteria and fungi in sensitive wards of an academic pediatric hospital Aerobiologia (IF 2.708) Pub Date : 2020-01-16 Seyed Hamed Mirhoseini; Mojtaba Didehdar; Majid Akbari; Rahmatollah Moradzadeh; Reza Jamshidi; Sara Torabi
Airborne bacteria and fungi in hospital environments are of great concern due to their potential role as a source of nosocomial infections. The aim of this study was to evaluate concentration and diversity of airborne bacteria and fungi in relation to particle mass concentration in sensitive wards of a pediatric hospital. The study was performed in the cardiac care unit (CCU), the neonatal intensive
