Air Quality Issue
There are several point & Cluster sources of Air Pollution, including industries, residential, burning of waste by Municipalities, dust from uncovered area, etc. But the major hazardous air pollutants are from industries (mainly from burning of fossil fuels), however, the main cause for daily commuters would be dust from uncovered areas of the road-side. To start with first step, let us try to develop uncovered areas with carpet grass or any wild grass and provide water sources on a regular basis either through drip irrigation or Municipalities. After each quarter check the PM10 and 2.5, carbon, SO2 in that area, this will help in assessing the real cause for air pollution(whether it is chemical based, petrol/diesel or dust). Just a thought. If anybody has any generated scientific data for any of the areas in Delhi including characteristics and sources, please share on this platform, this may be helpful to assess the cause. Wish you all a Healthy and Happy New Year-2019 more

You said "the main cause for daily commuters would be dust from uncovered areas of the road-side". This is only partially correct as many / most roads (be it in cities, towns or villages) are so poorly built that many pot holes ensure free flow of dust particles on roads. Corruption (in awarding contracts to build roads), lack of transperancy (specifications of road quality), and lack of proper supervision during and post construction of road is making each road (barring a few exceptions) a hell in India. Lack of public awareness adds to it. more

Pankaj, I was giving a general scenario with the pollution issue. Not giving any of my assessment on this platform. These are only comments. There is nobody right or wrong in this circle, it is what you think and share your opinion. Good day. more

Good suggestion. But how are we sure that whatever fuel petrol, diesel, industrial fuels, coal, is complying with EPA norms? Have you seen on any retail outlets the test certificate displayed for public notice. Has anytime our CPCB or SPCB ever carried out cross check such fuels ,taking samples from the oil tankers at production sites or at retail outlets? Yes growing weeds or other plants along the road sides, will certainly help in reducing pollutants as explained by you. But that is not sufficient n also difficult to maintain. As far as SPM is concerned the construction sites debris, the sand n the neighborhood desert region in Rajasthan Kutch region one cannot control or can cover it. But sure the SPM percentage varies with seasonal winds. In the city areas where ever possible local municipality can install water fountains, sprinklers to make those SPM bit heavier n can comedown to the ground. I have never seen anyone has data of such SPM composition or other suspended particles in air due to smog. But yes if want can be analysed with proper test methods. The aerial gas/ air samples analysis can also throw more meaningful data. For this where ever govt has installed aerial air quality monitoring stations fixed n mobile must be having specific analysers. Only reporting SPM is not sufficient. more
