India has been suffering with Air Pollution for a long time and was quite aware in 90’s when its Capital Delhi and Chinese capital Beijing were the countries with worst AQI. Both the countries pledged to control it and adopted measures. Beijing effectively, brought it down, while in India it went up. India has a good set up, dealing in Environment with huge back up to ensure control, has research and Government administrative set up to do research / studies to work out plan of action. Many actions were initiated, though ‘Implementation’ may be termed poor. I suggest few studies to have complete information on Sources, Parameters, their Spread and Quantum in an area. Based on this background, plan & implement control measures. Enemical practices to Environment should be controlled and stopped ruthlessly, any where including in Industries.
Life giver has become life taker. Now a days, the main talk and concern is Air Quality. The Air Pollution is caused by Particulate Matter, SOx, NOx, Carbon monoxide, Hydrogen fluoride, Volatile organic compounds, Chlorofluorocarbons, Ammonia, Aldehydes and organic acids, Smog and Ground-level ozone & lead etc.
Lets have a look at the background & trend of Air Quality in our country and also some other countries.
Delhi and Beijing, the most populated capital cities, competed with each other, for the infamous tag of being the world’s most polluted cities. Both countries claimed to have adopted control measures to reduce Particulate Matter.
The result of the efforts is as given below:
- Delhi sees steady rise in PM emissions even as Beijing’s effort bear fruit. In 2009, PM 2.5 levels in Beijing were far higher that Delhi’s. By 2017, however, emissions in India’s capital are nearly the double of its Chinese counterpart.
- As on November 13th, 2019 : AQI in India, China and US + Some other Countries
Lucknow (Lalbagh): 329; Delhi (Narela) :523; Beijing :28; France:18; Denmark: 13
U K :10; Brazil:8; U S:5
This very clearly indicates that if proper information, details about the pollution are collected, studied and accordingly control measures taken, the air pollution can be controlled to a very very minimal level like that in France, US, UK against the one which we are facing at Delhi (AQI: 414), Noida (AQI: 519) and Lucknow (AQI: 361), respectively.
Can one imagine the health emergency caused in our country, due to Air Quality, and compare air breathed by us & the citizens in some other countries!
It is generally known that the dust pollution is caused by Transportation, Construction Activity (Buildings as well as Roads), Poor Waste Management in the City – dumping and burning, Burning of stubbles by the farmers, Dust from large area of land with little or no vegetation, Deforestation etc
Looking into more depth, the pollution caused by Vehicular Traffic is due to No. of vehicles plying and the Quality of Road, which creates dust due to the friction caused by the tyre and the surface of road. If the surface of road is made, as done in foreign countries, the dust pollution will be hardly noticeable. Another factor is the Emission from the exhaust of the vehicle, which causes besides gaseous pollution also the Particulate Matter. Here, two aspects are relevant, one the Vehicle Engine Rating and the other, Emission Norms (Fuel Quality). Both of these need improvement in our Country for effective control of pollution. One can have an idea by seeing the Engine Rating and Emission Standards of India and E U etc. Alongwit, ‘Traffic Flow Management’; Study and correction measures are essential!
Further, unimaginable, undesirable and unscientific practices are still in vogue, even in Lucknow. Waste is being dumped adjacent to Public Toilet at Purania Chauraha, in the vicinity of Kendriya Bhawan, U P Panchayat Deptt and in front of Arif Shopping Complex.
Everybody in the country is concerned including highest authority of country i.e MOEFCC (Govt of India), who launched “National Clean Air Programme (NCAP)”, to be implemented in all states in the Country.
- The NCAP will be a mid-term, five-year action plan with 2019 as the first year.
- The center has fixed a target of reducing air pollution by 20-30% in 102 cities across the country by 2024, taking 2017 as base year.
- The Centre has earmarked Rs 300 crore for implementation of the National Clean Air Programme (NCAP) for the FY 2018-19 & FY 2019-20.
- The approach for NCAP includes collaborative, multi-scale and cross-sectoral coordination between the relevant central ministries, state governments and local bodies.
- Formation of 4 State Level Committee including one under the Chairmanship of Chief Secretary in the States + other Committees
Being a burning public issues, hurting everyone without exception, the deliberation and action plan of the committees should be known to the public. Further there should be participation of experts even from Non Govt. Institution with ground to earth experience. It is obvious, that experience and understanding of the issue in different set of conditions and thinking, may differ. Hence interaction & blend of experts opinion will be very desirable to be realistic to face the ground issues .
The notification of NCAP was issued on April 17, 2018, providing various committees at various levels - but one doesn’t remember to have heard or seen any information / news any where about the deliberations, the findings, actions taken, leave apart any encouragement to involve those engaged in environmental pollution control jobs in Private Sector to share and interact their findings & views in the matter.
NCAP & other plans like ‘EPCA’ and GRAP have failed. Main reasons being ‘Implementation & its mode’.
Further, I think, Action Plan should be supplemented with Basic Data /Information to plan corrective action after knowing the Quantum, Location and Details of the problem. For this, 3 aspects at an areas are essential. [I have been conveying this for quite some times – in the seminar on ‘ Air Pollution’ on World Environment Day, this year]
- Carrying Capacity
- Emission Inventory
- Dispersion Modeling
As far as Carrying Capacity is concerned, the Air Quality Index is clearly indicating that as regards ‘Air’, it has far exceeded the carrying capacity limit & needs no study but action to bring it down.
It involves, an accounting of the amount of pollutants discharged in the atmosphere. It contains the total Emission for one or more pollution parameters originating from all source categories [like no. of Vehicular movement, Vehicular emission, Construction activities burning of stubbles, burning of waste etc.], in a geographical area, within a specified time span. The study indicates the following:
- The types of activities that cause emissions & their contribution
- The chemical or physical identity of the pollutants and the quantity.
- The area covered
- The time period
The third information – ‘Dispersion Modeling’ will connect the sources, quantum of pollutants, the areas impacted and extent.
Once the pollutants are released into air, their fate is solely determined by the atmospheric conditions mentioned below:
- Temperature - Dispersion
- Wind – Caries away
- Turbulence – Mixes
- Rain – Washes
- Humidity - Agglomerate
The quality of air is expressed as Air Quality Index (AQI) i.e the level of pollutants in air and its impact. It ranges from 0 (Least Concern) to 500 (greatest concern) as per existing decided 5 categories.
HOWEVER THE PRESENT SCENARIO HAS EVEN EXCEEDED THE WORST AQI ENVISAGED (401-500), CATEGORY.
