Short summary
The air pollution associated with fine particles and secondary organic aerosol is not weakened by the application of mist cannon trucks but rather is aggravated. Our results provide not only new insights into the formation processes of aerosol water-soluble organic compounds associated with the water mist sprayed by mist cannon trucks in the road atmospheric environment but also crucial information for the decision makers to regulate the operation of mist cannon trucks in many cities in China.
