Spatial and Temporal Variation of Bioaerosols with Meteorology at Different Land Sites

Sonal Jain, Ankit Sharma, Ankita Singh

Abstract


Air particulates associated with biological origins are termed as bioaerosols. These bioaerosols consist of different species of bacteria, fungi, pollen and spores, etc. and can be allergenic and infectious in nature. The study is an attempt to understand the seasonal variation in bioaerosols concentration at three different land use sites: site I (commercial site), site II (dumping site), Site III (vegetated site). Statistical correlation was applied to infer the relation between bioaerosols concentration with meterological parameters (relative humidity and temperature) at selected sites. The study showed that Site II (dumping site) has high bioaerosols concentration (129 CFU) with high bacterial number (80 CFU) whereas the site III (vegetated site) has highest fungal concentration (67.8 CFU). This shows that different land use type and their micro habitat affect the type of biogenic agent that harbour. The bacterial and fungal concentration shows anti-synergistic trends with RH and temperature at different land use pattern. Contrastingly, at site II (dumping site) where the RH (42.5%) is observed to be minimum and are accompanied with maximum bacterial count.. Study demonstrates the strong correlation between temperature and abundance of bacteria indicated that temperature is one of the most important meteorological factors controlling bacterial abundance whereas the humidity exceeds the fungal population. In winter season the fungal concentration dominates the ambient environment whereas in summer season the bacterial spores were contributing most.
