A rainy spell early yesterday brought better air to residents of New Delhi, giving them a brief respite from thick grey smog that has shrouded the Indian capital for the last two months, despite air quality remaining to be “very poor”.
A measure of tiny, hazardous breathable particles known as PM 2.5 reached an average of 182 by 12 afternoon, its lowest since November 4 last, according to the Central Pollution Control Board. But pollution was still five times more than a US government recommended level of 35 to stand at “unhealthy” levels, says to the US embassy in India, reports Reuters.
“Change in weather conditions by rain or higher wind speed helps dissipate peak pollution, but we continue to need strong emergency actions such as shutting power plants,” said Anumita Roychowdhury of the Centre for Science and Environment think-tank.
The federal government air quality index rated Delhi’s air quality “very poor” yesterday, forecasting a similar situation today.
It also urged locals with respiratory and cardiac problems to avoid polluted areas and limit outdoor movement.
A sharp decline in temperatures and wind speed over the last two weeks, coupled with vehicle and industrial emissions, dust from building sites and smoke from garbage burning has stoked pollution over much of north India.
Levels of PM 2.5, or particles smaller than 2.5 microns in diameter, hit their highest last year at 450 on December 23.
Despite the pollution, there is little sign Delhi’s 20 million residents are taking steps to protect themselves. Activists say the apparent lack of concern gives politicians the cover they need for not tackling the issue adequately.
