Abstract:
Particulate air pollution is a countrywide public health problem in India, contributing to 2.5 million premature deaths annually. Since 2016 India's Central Pollution Control Board (CPCB) has been expanding their network of ground-based measurements of fine particulate matter (PM2.5). In light of newly available data from this network, we have revisited our previous analysis, "India's Air Pollution Crisis: By the Numbers" (McNeill and Nunes, HuffPost India 2017). We have analyzed ground-based PM2.5 data from CPCB instruments in 25 Indian cities in 17 Indian states from January 2019-January 2020. 24 hour average data is categorized in terms of the Indian National Ambient Air Quality Standard, the international/U.S. air quality index, and the Indian air quality index. We will discuss trends, regional variations, and changes since 2016-2017. Implications for public health are discussed.
