Every year, the 5th of June is observed as the World Environment Day to “encourage worldwide awareness and action to protect our environment”. For 2019, the theme is ‘Air Pollution’, and the host country is China. On this occasion, Research Matters caught up with three leading scientists from the country that are actively pursuing research on different aspects of air pollution. The three researchers, Prof. A R Ravishankara, Prof. S K Satheesh and Prof. Navakanta Bhat shared their work and thoughts on the ‘burning’ problem of air pollution.

Researchers from the USA and Canada estimated the incidence of asthma among children across the world that is triggered by nitrogen dioxide—a major constituent of the vehicular exhaust.
Researchers estimate that half of these deaths, resulting in India and China, can be prevented.
Researchers from about 100 institutions across India, present a comprehensive picture of the deaths, diseases and reduced life expectancy caused by polluted air in different states of India.
Researchers from the Johns Hopkins School of Medicine and the Byramjee Jeejeebhoy Government Medical College and Sassoon Government Hospitals study how household air pollution can affect tuberculosis.
With nine of the ten most polluted cities in the world located in India, the country is grappling with increasing pollution that is affecting the health and wealth of its people. In Delhi, the national capital, the news of increased particulate matter in the air hits the headlines very often. Although anti-pollution masks and air purifiers have gained popularity, they are often expensive and inaccessible to the common man.
In a new study, to be published in the journal Aerosol and Air Quality Research, researchers from the Indian Institute of Technology Bhubaneswar, take a closer look at various factors that caused air pollution during Diwali of 2016.
According to the World Health Organization, the safe limit of PM2.5 concentration for humans is 25 micrograms/cubic metre. But, the fact that at any given time, the PM2.5 levels in Delhi hover between 303.9 and 408.2 -- way above the safe level -- is no news! Newspaper headlines scream on toxic pollution levels and people wearing protective masks has become a common sight.
3.6 million lives could be lost in 2050 due to air pollution, says a recent study.
According to a new study by researchers from the Indian Institute of Technology-Bombay (IIT-B), the Health Effects Institute (HEI), and the Institute for Health Metrics and Evaluation (IHME), in 2015, only one in 1000 Indians lived in areas where particulate pollution did not exceed the permissible levels prescribed by World Health Organization (WHO).
Most studies on air pollution focus on intra-city roads. In India, highways constitute 40% of the traffic, making it important to effects of air pollution on and near highways. Scientists from IIT, Kharagpur explore this understudied phenomenon.
