is the potential for bioaerosols generated to disperse some distance from the point source. Consequently, there is concern that people living or working in the vicinity of waste composting sites (sensitive receptors) may also be exposed to these bioaerosols. Bioaerosols were sampled at sites representative of commercial scale waste composting

BIOAEROSOLS Introduction Bioaerosols are integral part of our ecological system and play an important role in its balance Viruses, bacteria, fungi etc. are collectively called airborne biological contaminants or Bioaerosols Outdoor control of Bioaerosols is usually not possible but indoors, it is achievable Most of the Bioaerosols host on humans and moist places, which provide habitable
Mar 28, 2021 17 studies were included in the systematic review, and 6 in different sets of meta- analyses. The pooled estimate of particle density was 390.74 μg/ Bio aerosols is a recognized consequence of certain types of dental treatment and represents a potential mechanism for the spread of infection [1]. Spread of Aug 13, 2013 There are many factors within the physical environment that affect the launching, transport and deposition of bioaerosols. Particles which become particle with aspect ratio of greater than 3:1; Bioaerosols – Airborne particles that originate from living organisms (i.e., pollen, spores, fragments, waste).
Bioaerosols in the troposphere may act as efficient cloud condensation nuclei or ice nuclei thus affecting cloud formation and evolution . Knowledge of the nature and sources of ice nucleation in the atmosphere is important for understanding the meteorological processes for precipitation [7,8].

Though there are significantly less atmospheric microorganisms than there are in oceans and in soil, there is still a large enough number that they can affect the atmosphere (Amato, 2012).
1.The launching of bioaerosols into the air 2.The subsequent transport via diffusion and dispersion of these particles 3.Deposition The launching: The process whereby particles become suspended within the earth’s atmosphere. Airborne particles can be launched from either point linear or area source.

Seasonal changes are also linked with modulation of airborne biological agents that have a significant impact on human health (e.g., pollens and spores) and means of monitoring and evaluating their impact is currently Besides direct health effects, bioaerosols also impact public health and ecology through their global transport and acting as ice nuclei (IN) and cloud condensation nuclei (CCN). Humans are facing increased threats of biological aerosol infections.
