Air pollution in Delhi and therefore the whole of the Indo-Gangetic Plains may be a complex phenomenon that’s hooked in to a spread of things . But, per annum in October, Delhi’s air quality starts to dip.

Factors liable for this:

1. Withdrawal of monsoons:

During summers, too, the direction of wind is north westerly and storms carry dust from Rajasthan and sometimes Pakistan and Afghanistan.

2. Dip in Temperatures:

As temperature dips, the inversion height — which is that the layer beyond which pollutants cannot disperse into the upper layer of the atmosphere – is lowered. The concentration of pollutants within the air increases when this happens.

3. High-speed winds:

They are very effective at dispersing pollutants, but winters bring a dip in wind speed over all as compared to in summers.

4. Farm fires:

A 2015 source-apportionment study on Delhi’s pollution conducted by IIT-Kanpur also states that 17-26% of all particulate in Delhi in winters is due to biomass burning.

5. Dust pollution:

Dry weather means dust is prevalent within the entire region, which doesn’t see many rainy days between October and June. Dust pollution contributes to 56% of PM 10 and and therefore the PM2.5 load at 59 t/d, the highest contributors being road 38 you look after PM 2.5 concentration.

6. Vehicular pollution:

It is the second biggest explanation for pollution in winters. consistent with the IIT Kanpur study, 20 you look after PM 2.5 in winters comes from vehicular pollution.

Measures to enhance air quality:

• Improving conveyance

• Limiting the amount of polluting vehicles on the road

• Introducing less polluting fuel

• Strict emission regulations

• Moving from diesel generators to rooftop solar

• Increased use of unpolluted renewable energy

• Electric vehicles

• Removing dust from roads

• Regulating construction activities

• Stopping biomass burning, etc
