Concentrations of Aerosol Numbers and Airborne Bacteria and Temperature and Relative Humidity and Their Interrelationships in a Tie-Stall Dairy Barn

摘要

Aerosol particles are important elements of atmospheric pollution. Livestock barns are some of the most crucial anthropogenic sources of generation and emission of aerosol particles to the surrounding environment. Along with environmental pollution, these particles can cause numerous diseases in humans and animals. Besides causing diseases, these particles are said to have a significant role in the transmission of infectious diseases. Microorganisms that bind to aerosol particles are known as bioaerosols, which ultimately spread diseases in and between farms. Environmental factors such as temperatures (temp.) and relative humidity (RH) may have significant effects on aerosol particles and airborne bacteria. The present study was undertaken to find out which factors have more significant effects on the regulation of aerosol particles and airborne bacteria in the dairy environment. In the present study, we found that temperatures have profound effects on the regulation of aerosol numbers and various airborne bacteria. This temperature-dependent emission inventory of aerosol particles and various airborne bacteria will play a crucial factor in the mitigation of aerosol particles and various airborne bacteria in the dairy environment.
