In the model created by the researchers, air pollution was found to be responsible for 11% of changes in average antibiotic resistance levels globally, possibly making particle pollution a leading driver.

However, the study, which examined nine bacterial pathogens and 43 types of antibiotics, is observational and can’t prove a connection or explain what the connection would be.

The study suggests every 1% increase in air pollution can be linked to a rise in antibiotic resistance between 0.5 and 1.9%, based on the pathogen.
