The global pandemic led to a drop in outdoor air pollution, but it also led to an increase in indoor air pollution - and our exposure to it. LEARN MORE ************** To learn more about this topic, start your googling with these keywords: Particulate matter: often abbreviated PM, it is the sum of all the tiny particles and drops of liquid suspended in the air including soil, soot, dust, metals, and acids like nitrates. Air quality: a measurement of how polluted the air is, judged by the level of known pollutants in the air like NO2 and particulate matter like soot. Ozonolysis: an organic chemical reaction wherein ozone cleaves a carbon-carbon bond in unsaturated compounds.
