Impact of COVID‐19 lockdown on the elemental profile of PM10 present in the ambient aerosol of an educational institute in Kolkata, India

ABSTRACT: Abstract Reduction in air pollution level was prime observation during COVID‐19 lockdown globally. Here, the study was conducted to assess the impact of lockdown on the elemental profile of PM10 in ambient aerosol to quantify the elemental variation. To quantify the variation, phase‐wise sampling of air pollutants was carried out using the gravimetric method for PM10, while NO2 and SO2 were estimated through the chemiluminescence and fluorescent spectrometric method respectively. The elemental constituents of PM10 were carried out using an Inductively Coupled Plasma Optical Emission Spectrometer and their source apportionment was carried out using the Positive Matrix Factorization model. The results showed that PM10, NO2 and SO2 reduced by 86.97%, 83.38%, and 88.60% respectively during the
