Question

Anyone to tell me levels of nitrogen dioxide & sulphur dioxide in delhi??plz help & jaldi?

Answer 1

A study by the Washington-based Resources for the Future (RFF) found that sulphur dioxide and carbon monoxide levels -- which cause respiratory and heart problems -- have dropped by about 80 percent and 70 percent, respectively, since 1997.

But nitrogen dioxide levels have increased by about 30 percent to 100 micrograms per cubic metre since then, well above the permissible limit of 60, the study's co-author said.
