    15/16 What can you do to improve outdoor air quality? A collective effort is needed from governments and companies that influence individual actions. Ban of wood and biomass stove burning is needed especially in urban settings. Limit traffic across all roads in a city too.

    13/16 How PM2.5 impact human health? The smaller the particles the deeper they go inside our bodies. PM2.5 is around 2,500 nanometres in diameter. However, nanoparticles are 100nm or less. In comparison, they are 25 smaller, as a result, they can reach any organ in our bodies.

    12/16 Why mass concentration is not adequate to measure PM1 and UFP? Governmental authorities monitor PM2.5 by mass micrograms per cubic meter (μg/m3), consequently, million of nanoparticles may not even register in a single measurement by microgram.

    11/16 Should we measure PM10, PM1, and UFP apart from PM2.5? Experts claim that PM1 is a better indicator for a roadside micro-environment than PM2.5. Recent research suggests that UPFs could be responsible for illness and death beyond our current understanding.

    8/16 Why we need to measure PM2.5 indoors and outdoors? There is a great relationship between both environments as we exchange air. We need to ventilate indoor air to dilute some chemicals and CO2. Buildings tend to have 50% of the pollutants present in the ambient air
