The festive fervour gripped the nation on Thursday as people celebrated Diwali, often referred to as 'the by lighting diyas (earthen lamps), paying obeisance to Goddess Lakshmi, distributing sweets. However, a quiet and promising evening gave way to thick haze and noise as Delhi celebrated Diwali, dashing the hopes of cracker-free festivities, following a Supreme Court ban on the sale of firecrackers in the Capital Region (NCR).

The cracker-bursting was relatively subdued as compared to previous years. However, the revelers in the adjoining townships of Delhi such as Noida, Gurgaon and Faridabad paid little heed to the apex court's writ and environmentalists' concerns.

Real-time pollution data alarming

The online indicators of the pollution monitoring stations in the city glowed red, indicating a 'very poor' as the volume of ultrafine particulates PM 2.5 and PM 10, which enter the respiratory system and manage to reach the bloodstream, sharply rose from around 7 pm.


At 10 pm, in Mandir Marg in Delhi, the PM 2.5 concentration was 390 units against the prescribed 60 units, while PM 10 was 480 against the prescribed 100.

Real-time pollution data appeared alarming. The Delhi Pollution Control Committee's (DPCC) R K Puram monitoring station recorded PM 2.5 and PM 10 at 878 and 1,179 micrograms per cubic metre at around 11 pm.

However, the nitrogen dioxide and sulphur dioxide concentrations at 50.84 and 31.20 respectively were well under the prescribed limits.

The pollutants had violated the corresponding 24-hour safe limits of 60 and 100 respectively by up to 10 times.

While it is difficult to quantify the immediate effect of the ban on firecrackers, residents across the capital felt the beginning was promising with neighbourhoods reporting much lesser noise and smoke till about 6 pm, compared to the previous years.

But as the festivities picked up, the faint echo of crackers started growing louder.

According to the SAFAR (System of and Weather Forecasting And Research), the 24-hour rolling average of PM2.5 and PM10 were 154 and 256 micrograms per cubic metre respectively at around 11 pm.

It has forecast that the pollution levels will peak between 11 pm and 3 am.

The situation was similar, if not worse, in the neighbouring regions of Delhi such as Gurugram, and Ghaziabad, where crackers were burst as usual, raising question marks on the efficacy of the administration in enforcing the apex court's ban.

However, the SAFAR has also predicted a relatively cleaner post-Diwali air due to favourable meteorological conditions, which are helping prevent the smoke-filled air from the agricultural belt of and from entering the capital.

A 'very poor' index (AQI) essentially means that people may suffer from respiratory illnesses on a prolonged exposure to such air. If the dips further, the AQI will turn 'severe', which may trouble even those with sound health conditions and seriously affect those with ailments.

The Supreme Court-appointed Environment Pollution Prevention and Control Authority (EPCA) is empowered to enforce the Graded Response Action Plan (GRAP) to combat in Delhi-NCR.

Measures under the GRAP's 'very poor' and 'severe' categories, which include a ban on diesel generator sets, came into effect on October 17 and they will remain in force till March 15.

In Amritsar, fireworks display and the newly-installed LEDs lighting marked the celebrations of Diwali and "Bandi Chhor Diwas" as thousands of devotees flocked to the complex.

However, the duration of fireworks display was shortened owing to environmental concerns.

How celebrated Diwali

The guru and the princes arrived in during Diwali festivities. Since then, the Bandi Chhor Diwas and Diwali celebrations coincide at the complex.

People across the state exchanged sweets and savouries with friends, neighbours and relatives. The festival saw the mingling of a sizeable population of non-Bengali communities (Marwari, Gujarati, Bihari) and Bengalis across the state to celebrate Diwali.

Ululations (high pitched vocal sounds) and peals of bells resonated across temples and residences observing Kali Puja, adding to the festive spirit.

People hit the streets in their best ethnic wears, making way through various marquees and stopping for a bite.

In Odisha, heavy rainfall on Thursday dampened Diwali celebrations and the festive spirit, forcing the people to stay indoors.
