The reuse or recycling of wastewater provides environmental and economic benefits, representing a sustainable and circular alternative for the management of liquid waste. However, the application of effluents to agricultural crops via spraying creates a potentially dangerous situation for individuals exposed to airborne pathogens. This study used Quantitative Microbial Risk Assessment (QMRA) tools to quantitatively assess the microbial risks of occupational and public exposures to bioaerosols in fertigation scenarios by spraying untreated and treated dairy cattle wastewater. Analyses of Escherichia coli (EC) and spores of Clostridium perfringens (CpSP) in raw and treated effluents aswell as pathogen / indicator ratios fromthe literaturewere used to estimate the concentrations of Escherichia coli O157:H7 (EC O157:H7) and Cryptospodirium spp. (Crypto) in the air, and the results were applied to an atmospheric microbiological dispersion model. From the concentrations of pathogens in the air, infectious risks for downwind receptors were calculated. The risks of infection by EC O157:H7 to workers at 10mand 50maway fromthe emission source ranged between 3.81 × 10 1 and 2.68 × 10 3 pppy (per person per year), whereas to residents at 100m and 500 m ranged from4.59 × 10 1 to 1.51 × 10 4 pppy. Peak values (95th percentile) of occupational and public risks associated with the exposure to Crypto were 3.41 × 10 3 and 6.84× 10 4 pppy at 10mand 50mfromthe source, respectively, and were lower than 1.48× 10 6 pppy regarding. exposures to CpSP. Anaerobic digestion reduced risks by approximately one order of magnitude. The distance fromthe sourcewas inversely proportional to the risk of exposure. It is recommended that wastewater is treated prior to its reuse and the adoption of application methodswith lowaerosolization potential. In addition, the need for workers to use personal protective equipment (PPE) is highlighted.
