National Study on Residential Impact of Biological Aerosols from Land Application of Biosolids Finds Low Microbial Risks of Infection (Posted August 1, 2005)

A national study was conducted by the University of Arizona (Tucson) on the residential impact of biological aerosols from the land application of biosolids. The purpose of this study was to evaluate the community risk of infection from bioaerosols to residents living near biosolids land application sites. The study results led to the conclusion that overall bioaerosol exposure from biosolids operations poses little community risk. The study evaluated the overall incidence of aerosolized microorganisms from the land application of biosolids and subsequently determined that microbial risks of infection were low for residents close to biosolids application sites. The study results were published in the Journal of Applied Microbiology, 2005, 99, 310-322. To view the study, visit the National Biosolids Partnership’s web page –
