Diurnal Variation of Air Quality Parameters- PM2.5 and PM10 During and Post Pandemic Period in Delhi, India

Abstract

Particulate matter in the air is the contamination, considered dangerous to human health. Particulate Matter includes a mixture of solid and liquid particles suspended in the environment. Its tiny size allows the particles to enter the circulation system through breath and travel all through the body, causing asthma and heart illness. Coronavirus has been pronounced as a Public Health Emergency of International Concern by WHO on 30th January 2020. The current examination aims to compare air quality (with respect to PM2.5 and PM10) at pre-selected locations during and post COVID- 19 phase. To lead this investigation the monitoring station for air quality measuring chose is close to Hauz Khas metro station, Delhi. Complete 4 locations are chosen around CPCB Air pollution monitoring station, Hauz Khas. PM testing has been accomplished for nonstop 12 days. The monitoring time considered is from 10 am to 6 pm (8 hours). The dataset of the period (March and April of 2020) of the lockdown stage is gathered from CPCB and compared with the dataset of a similar time span (March and April 2021) utilizing Origin software programming. The contamination level increased after the lockdown stage as per the present study and improvement in air quality couldn't keep going long after the returning of businesses and vehicular exercises as per this examination.
