Health Desk: 19 April 2018: A global study has warned that the air quality in Bangladesh has falling fast since 2010, taking the concentration of dangerous substance, known as particulate matter or PM 2.5, in the air to 10 times higher than the maximum level set by the World Health Organisation (WHO), reports BSS.

WHO has set the safe level of the substance to 10’g/m3 (one-millionth of a gram) while it was 101’g/m3 in Bangladesh’s air in 2016, according to the State of Global Air-2018 report, released in the United States on Tuesday.

Pakistan, Bangladesh and India have experienced the steepest increases in air pollution levels since 2010 and now demonstrates the highest sustained concentration of dangerous matter in the air, the report said.

A survey conducted from 2013 to 2016, by the Department of Environment (DoE) of Bangladesh, on air quality in Dhaka detected that of the PM 2.5 58 percent in the capital city comes from traditional brickfields, while road dust is liable for 15 percent and motor vehicles 10.4 percent.

The DoE in its annual report for 2016-17 highlighted some of the government’s initiatives to control air pollution. These include modernisation of brick kilns, controlling black smoke emitting motor vehicles and creating mass awareness to remove the man-made causes of air pollution.
