The statement noted that strong dust storm activities that occurred during August 26 and 28 also led to a transient increase in PM10 concentrations. Despite this scenario, the daily average AQI for all 31 days in the month of August remained in the “Satisfactory – Moderate” air quality category.
Delhi witnessed the highest number of days (163) with “Good” to “Moderate” air quality (Daily Average AQI<200) during January to August 2023 as compared to the corresponding period for the last 5 years (barring the COVID affected 2020), it added.
As per the official statement, “Good” to “Moderate” air quality days during this period in the previous years were only 116 in 2022, 144 in 2021, 135 in 2019 and 123 in 2018 respectively.
This period in 2023 has also witnessed a remarkable reduction in daily average PM2.5 and PM10 concentrations over the last 6 years.
The period during January-August in 2023 has recorded daily average PM2.5 concentrations of about 77 µgm/m3 as against ranging from 85-97 µgm/m3 during the corresponding periods from 2017 to 2022 (barring the COVID affected 2020).

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – theLGBTQ population,indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the currentCOVID-19 pandemic, the need for WASH (Water,SanitationandHygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fightmalnutrition, mental wellbeing, self care, science and health,adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues likeair pollution,waste management,plastic ban,manual scavengingand sanitation workers andmenstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India wheretoiletsare used andopen defecation free (ODF)status achieved as part of the Swachh Bharat Abhiyan launched byPrime Minister Narendra Modiin 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
