Airborne bacterial community associated with fine particulate matter (PM_2.5) under different air quality indices in Temuco city, southern Chile.

ABSTRACT: Temuco (Chile) is one of the most polluted cities in Chile and Latin America. Although the fine fraction of particulate matter (PM_2.5) has been extensively studied and monitored due to its negative impact on public health, its microbiological components remain unknown. We explored, the airborne bacterial community in PM_2.5 under good, moderate, alert, pre-emergency and emergency indices of air quality (AQIs) established by the Chilean government. Bacterial community relationship with environmental factors (PM_2.5, PM₁₀, carbon monoxide, among others), was also evaluated. Significant differences in PM_2.5 bacterial community composition associated with AQIs were revealed, using 16S rRNA target sequences of denaturing gradient gel electrop
