Air pollution is increasingly understood as a global issue, requiring an understanding of pollution sources, transport, and transformation from local to regional to global scales (IPCC, 2013).

This study reviews and compares five databases (three global and two regional) that provide emission estimates for air pollutants in India. These databases include EDGARv5, ECLIPSEv6b, REASv3.2, SMoGv1 and TERI (2016).

New WHO Global Air Quality Guidelines (AQGs) provide clear evidence of the damage air pollution inflicts on human health, at even lower concentrations than previously understood.

This review of the epidemiological literature on fugitive dust indicates the likelihood of significant public health impacts from both short- and long-term exposure to both fine and coarse dust. These impacts are observed in populations that are both near to and distant from the original dust sources.

The aim of this report is to estimate the impact of air pollution on health in contemporary Accra, Ghana. Accra is a city that has experienced rapid growth in the last decades.

Non-exhaust emissions of particulate matter constitute a little-known but rising share of emissions from road traffic and have significant negative impacts on public health. This report synthesizes the current state of knowledge about the nature, causes, and consequences of non-exhaust particulate emissions.

It is evident that as compared to lockdown period, air quality in terms of Air Quality Index has remained ‘Satisfactory’ during modified lockdown period at all the towns except at Jodhpur where it has worsened to ‘Moderate’ Category.

The nationwide Lockdown, in effect since the midnight of 24 March in view of COVID-19 pandemic, has resulted in significant improvement in air quality in the country, as revealed by data analysis and comparison of data for time before enforcement of restrictions.

The nationwide Janta Curfew on March 22, 2020 and lockdown since March 24, 2020, have resulted in significant improvement in air quality in the country, as revealed by data analysis and comparison of data for time before enforcement of restrictions.

As per data from Central Bureau of Health Intelligence (CBHI), State / Union Territory (UT) wise details of cases of Acute Respiratory Infection (ARI),in the country during the years 2016-2018 are given in Annexure. In January 2019, Government launched National Clean Air Programme (NCAP) to tackle the problem of air pollution in a comprehensive manner with targets to achieve 20 to 30 %reduction in PM10 and PM2.5 concentrations by 2024, keeping 2017 as base year.
