This digital tool allows visualization of relationship between air pollutants and respiratory illnesses using various graphs and user can evaluate on various selection criteria.As per this model, when PM 2.5 level rise from 60 to 225 μg/m 3, then nearly 11% increase in clinic visits is expected for respiratory health effects under normal conditions. As it estimates the increase in the Mohalla clinic visits for short- term respiratory illnesses in the local community. This tool explores several PM 2.5 level-based scenarios to assess health benefits. One of the key team members include Professor Sujit Kumar Ghosh 6, Department of Statistics, North Carolina University and also serve as Distinguished Visiting Fellow at TERI. Tool-predicting clinic visits from air pollutionĪ statistical (GAM-Generalized Additive Model) predictive model based digital tool 5 has been developed by TERI's Environment and Health team for the Delhi-NCR region. Due to the lockdown, the PM 2.5 level at Anand Vihar has seen a huge dip and we have already achieved the National Ambient Air Quality Standard (NAAQS) limit of 60 μg/m 3. It is a clear visualization of how PM 2.5 level has dropped remarkably (76 μg/m 3) on 25 March as compared to the same day in the previous years. This is a dramatic change as compared to daily 24- hour average PM 2.5 data 4 of March in the last three consecutive years from 2018-20 (graph attached). Otherwise, this area has been notorious with the worst air quality status and as one of the major air pollution hotspots of Delhi. PM 2.5 is considered particularly dangerous as it can be inhaled deep into the lungs causing respiratory illnesses 3.īy the first week of the lockdown, the daily 24-hour average concentrations of particulate matter (PM 2.5) dropped by almost 70% in the Anand Vihar region of Delhi. It is, therefore, one of the criteria pollutants used to calculate Air Quality Index (AQI).

Particulate Matter (PM 2.5) or fine particulates with its diameter smaller than 2.5 μm has a direct impact on the human health. Within two weeks into the initial 21-day lockdown Delhi's air quality status had already achieved the 'satisfactory' (AQI 50-100) or 'good' (AQI 0-50) category. The sudden changes in the environment due to the current lockdown presents us with a unique learning situation in terms of considerable reduction in the air pollution levels. Globally, air pollution is the leading risk factor for public health and early death, contributing to adverse health conditions such as heart diseases, stroke, respiratory infections and lung cancer 2. The top Indian cities with the track record of world's worst air quality, this 1 is an unforeseen benefit amidst Coronavirus pandemic. The clear skies and clean air have turned out to be the blessings in disguise for the millions choking on polluted air across Indian cities. In an attempt to slow the spread of this infection, a 'total lockdown' has been imposed with restrictions on day-to-day movement and ban on all commercial and industrial activities. The novel Coronavirus (COVID-19) pandemic led to a nationwide lockdown affecting the life of 1.3 billion population across the country. During COVID-19 pandemic and subsequent lockdown, the clear skies and clean air have turned out to be the blessings in disguise for the millions affected due to air pollution in India.
