Estimation of bioaerosol risk of infection to residents adjacent to a land applied biosolids site using an empirically derived transport model

Abstract: Aim: The purpose of this study was to develop an empirically derived transport model, which could be used to predict downwind concentrations of viruses and bacteria during land application of liquid biosolids and subsequently assess microbial risk associated with this practice. Methods and Results: To develop the model, coliphage MS-2 and Escherichia coli were aerosolized after addition to water within a biosolids spray application truck, and bioaerosols were collected at discrete downwind distances ranging fr… Show more

“…Briefly, a transport model was utilized (Brooks et al 2005b) to determine the extent of aerosolization of total coliform bacteria from biosolids. Following this, ratios of total coliforms: Salmonella in the biosolids were used to estimate the extent of Salmonella aerosolization.…”

“…Research in the last 5 years has made significant progress in estimating the human exposure to total biosolid aerosols and biosolid indicator microorganisms. Advances include both the development and calibration of theoretical and empirically based microbial aerosol models to assess off-site exposure during land application operations (8,16,31,54) and the application of culture and DNA-based microbial-source tracking methods to these aerosols (5, 14). However, the paucity of information on the viral and bacterial pathogen content of biosolids has limited model use and effectiveness.…”

“…Aerosolization appears to be an inefficient phenomenon even when considering deliberate aerosolization from point sources such as spray-irrigation of inoculated water (Brooks et al, 2005b). This may be due to the low survival associated with aerosolized Enterobactericae, as shown by Teltsch et al (1980), or due to immediate dilution effects once in the air environment.…”

“…On the other hand, land-application scenarios occur on a field, at most, twice per year (Brooks et al, 2005b); needless to say, this significantly reduces exposures and contamination risks. Dungan (2011) reviewed the literature pertaining to CAFO-generated bioaerosols, and demonstrated that as with other scenarios, 200 m appears to be the furthest distance at which bioaerosols were above background.…”
