Twenty-two of the world’s 30 most polluted cities are in India, with Delhi being ranked as the most polluted capital city globally, a new report said . The report is prepared by Swiss organisation, IQAir, in the form of the ‘World Air Quality Report, 2020’, which has released globally.

PM2.5 air pollution was behind approximately 160,000 deaths in the world’s five most populous cities in 2020, according to a Greenpeace Southeast Asia analysis of IQAir data from a live Cost Estimator.

Real policy is not defensive short-term emergency measures but something proactive spanning multiple years, and acting fast, local and through multiple agencies. Every Diwali, a billion people in India wake up to the news of smog-ridden cities in the aftermath of celebratory fireworks.

This study investigates the causal effects of long-term particulate matter 2.5 exposure on COVID-19 deaths, fatality rates, and cases in India by using an instrumental variables approach based on thermal inversion episodes.

Many cities and urban centers around the world experience high air pollution episodes attributable to increased anthropogenic alterations of natural environmental systems. World Health Organization estimates indicate strong exceedances of prescribed limits in developing countries.

Maternal exposure to ambient particulate matter (PM2·5) is associated with pregnancy loss (ie, stillbirth and miscarriage). South Asia has the highest burden of pregnancy loss globally and is one of the most PM2·5 polluted regions in the world.

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.

Better air quality has led to a significant reduction of premature deaths over the past decade in Europe. However, the European Environment Agency’s (EEA) latest official data show that almost all Europeans still suffer from air pollution, leading to about 400,000 premature deaths across the continent.

Air pollution presents an increasingly apparent challenge to health and development across the globe. Exposure to PM2.5 is a major health risk and worldwide, an estimated 4.13-5.39 million people died prematurely in 2017 from exposure to PM2.5 pollution. The health impacts of pollution also represent a heavy cost to the economy.

This paper examines the relationship between contemporaneous exposure to fine particulate matter and COVID-19 morbidity and mortality.
