More than half of the 5.5 million deaths related to air pollution in 2013 happened in India and China, according to a new study.
About 1.4 million people in the South Asian nation and 1.6 million in its northern neighbor died of illnesses related to air pollution in 2013, researchers at the University of British Columbia in Canada said.
The Indian and Chinese fatalities accounted for 55% of such deaths worldwide, the study said.
Researchers studied risk factors for death and disease around the world and found that air pollution, both indoors and outdoors, was one of the leading contributors to global fatalities.
The inhalation of emissions from power plants, vehicles, the burning of crop stubble before replanting, and wood or open fires in homes are some of the leading causes of deaths from air pollution, the report said.
The number of premature deaths linked to air pollution worldwide will increase over the next two decades unless more aggressive targets are set to curb it, researchers studying India and China’s air said at a meeting Friday in Washington D.C.
A major contributor of poor air quality in India is linked to the burning of wood and cow dung for cooking and keeping warm, particularly in the winter months. These methods are popular among India’s rural and urban poor, who don’t have access to electricity or cleaner fuels.
Household air pollution from cooking with wood “is primarily a problem in rural areas of developing countries of the world,” said Michael Brauer, a professor at the University of British Columbia’s School of Population and Public Health, in Canada.
Over the past few months, levels of tiny insidious particles, known as PM 2.5, in the Indian capital New Delhi have often exceeded amounts deemed safe by the United Nations World Health Organization.
Taking their lead from Beijing, Indian authorities in January experimented with restricting cars on roads for two weeks in New Delhi to reduce emission levels. Delhi Chief Minister Arvind Kejriwal said Thursday the city would revive the restrictions for 15 days, starting April 15.
Scientists said vehicle emissions contribute only 20% to 40% of pollution in Delhi, saying other sources of the particulate matter include the burning of dung, rubbish and leaves and the use of diesel backup generators, which kick in when Delhi’s patchy electricity supply cuts out, as well as emissions from small-scale industries such as brick kilns.
A federal environmental court in New Delhi said Feb. 4 it wanted officials to improve air quality by asking authorities to reduce the number of traditional cremations that use wood to burn bodies, a widespread practice in majority Hindu India.
In China, outdoor air pollution from burning coal was found to be the biggest contributor to poor air quality, causing an estimated 366,000 deaths in the country in 2013. Scientists predict 1.3 million premature deaths will take place in China by 2030 if coal combustion remains unchecked.
“One of the unique things about air pollution is you cannot run, you cannot hide from it. We know that if you improve air quality everybody benefits, so from a health perspective reducing levels of air pollution is actually an incredibly efficient way to improve the health of the entire population,” Mr. Brauer said.
