The association between PM2.5 and clinical antibiotic resistance
Zhenchao Zhou and colleagues’ Article1 aims at providing evidence on the global relationship between particulate air pollution (PM)2.5 and antimicrobial resistance (AMR). Using national-level data for a sample of 116 countries from 2000 to 2018, they claim to use panel fixed effect models to analyse the effect of PM2.5 on antibiotic resistance for a range of bacteria. Their analysis shows that there are significant correlations between PM2.5 concentrations and antibiotic resistance, indicating an increase in antibiotic resistance of 0·43% for every unit increase in PM2.5.
