This study determined the effect size (ES, Cohen’s δ) and the significance of progressive quarantine restrictions levels national quarantine [NQ], smart quarantine [SQ], and focalized quarantine [FQ] on air pollution in BogotcE1, Colombia, during the COVID-19 pandemic. A natural experiment showed that, during SQ and FQ phases, concentrations of [PM₁₀, 20. 0 ug/m3; PM₂. ₅, 8. 03 ug/m3; SO, 1. 61 ug/m3] and [PM₁₀, 23. 2 ug/m3, PM₂. ₅, 8. 84 ug/m3], respectively, were significantly lower than during equivalent pre-pandemic periods (year 2019; p
