“…QMRA has been utilized to investigate the inhalation health risk of pathogens generated from reused water , and waste management facilities for livestock farms. , Recently, the QMRA method has been adopted to investigate the airborne infection risk of MERS-CoV in a hospital, which indicated that the daily mean risk of infection for the nurses and healthcare workers was relatively high (>10 –4 ) . Atmospheric dispersion models were utilized in the QMRA studies for foot-and-mouth-disease virus, − avian influenza virus, , Legionella , the spore-forming bacterium B.anthracis , − and the C. burnetii bacterium for Q fever. , The atmospheric dispersion models − estimate the temporal and spatial distribution of hazardous pollutants for a large scale and long period, which is difficult to achieve by field sampling and measurements. − Biologic decays were normally included in the models …”
