The city has a lot of red industries as a result of which the PM10 — tiny airborne particles seven times finer than human hair–exceeds national standards (60 micrograms per cubic metre, or μg/m3) by around 200 per cent. Indian Standards for PM10 is three times higher than WHO standards for PM10 particles which is 20 micrograms per cubic metre.
