Higher reductions can be achieved if policies are adopted to control other types of vehicles and non-exhaust emissions since they have a contribution of about 60%. Finally, this study shows that the combined use of emission calculations and advanced near-road dispersion models are useful tools to study and manage air quality in large cities.Wastewater treatment plants (WWTPs) play a vital role in public health because it can emit a large quantity of bioaerosols. Exposure to bioaerosols from WWTPs is a potential health risk to WWTP workers and surrounding residents. In this study, the seasonal fluctuation of aerosolization ratios of several bioaerosols and quantitative health risks of the WWTP workers and the surrounding residents exposed to total coliform, fecal coliform, and enterococcal bioaerosols were analyzed. Results showed that the aerosolization ratio of airborne bacteria was higher in the cold seasons and lower in the warm seasons, whereas the aerosolization ratio of airborne fungi was the highest in summer. The aerosolization ratio of airborne fungi was evidently higher than that of other bioaerosols. Moreover, the aerosolization ratio under the inverted umbrella aerator mode was generally higher than that under the microporous aerator mode. For each exposure scenario, the health risks of males were generally 7.2-26.7% higher than those of females. The health risks of the exposure population exposed to total coliform and enterococcal bioaerosols were generally higher in warm seasons, whereas those of the population exposed to fecal coliform bioaerosol were the highest in winter. Additionally, the health risks of exposure population without masks under the imprudent/conservative estimate all exceeded the benchmarks. However, when equipped with masks, all the exposure
