DELHI AIRPORT AND THE NEVER ENDING FOG - OR IS IT SMOG

Fog season in Gurgaon and Delhi starts normaly at the end of Nov and ends by the last days of January. Living now here for 5 years always in the vicinity of the airport it looks to me as if the combination of the natural ambient fog combines to the heavy air polution. India don't want to spent money on redicilous (they think) ambient emission measurement, there are only figures for particulates available, therefore the figures for SO2, CO , THC, NOx and O3 are unknow. I assume for good reasons these figures should not be measured, once published , tourist would avoid Delhi in particular and India in special. I assume that the 5 years in India I was more exposed to poisinious pollutants than all the rest of my live together.
Another city was famously exposed in dense fogs that brought visibility to zero, the LONDON of the Sherlock Holmes stories and the tales of Jack the Ripper.All this is history , London is now blessed with clear skies even on the most wintry days.
The clean air act of 1956 forced people to stop burning coal and wood to heat homes.
As long as India don't has any regulations for ambient pollutants and more important also the equipment to measure it, the situation with get worse and worse. In the automtive sector it is all good regulated but for ambient it is catastrophic and India should take the responsability not to invite any tourist, taking is health at risk.
