Description
Aníbal A Teherán and six colleagues measure, in a 2026 natural experiment, how much COVID-19 quarantine strictness cleaned the air of Bogotá, Colombia. Successive national, smart, and focalised quarantine phases during the pandemic created a rare graded test of traffic and industry shutdowns.
Pollutant levels during the smart and focalised phases were compared with matching pre-pandemic periods in 2019. Coarse and fine particle levels, plus sulphur dioxide in one phase, fell significantly, with the strictest focalised phase showing the largest standardised effect sizes. All values stayed below legal thresholds, prompting the authors to propose an added notion of environmental significance for judging whether a drop truly matters for wellbeing.
