How Diwali Firework result in Smoggy Fog in India

Diwali (the festival of lights) is the most important Hindu festival in India celebrated each autumn.

Lots of sparklers and fireworks were set off to celebrate the Hindu festival but the smoke caused heavy smog.

Burning loads of crackers on Diwali is a habit that the government cannot take away from Indians. 

The morning after Diwali in Delhi was all smog with residents left with no option but to breathe the poisonous air with pollution levels in many areas reaching levels 40 times over the safe limits.

A day after Indians marked the holiday of Diwali by setting off firecrackers in huge numbers, a toxic smog has covered the capital city. Pollution levels were at dangerous in most parts of the city  Monday morning (31 October 2016).

Environmental conditions like low wind speeds, cooler temperature and moist air contribute to extending the suspension of such pollutants near the ground.

Many areas in the city have zero visibility including the railway stations, highways and airports. Normal life slowed down in the morning as it became dangerous to navigate on roads due to the alarming drop in visibility.

There is now a serious risk of respiratory problems for people living in Delhi as the air quality index increase from safety levels of 150 to 999

The particulate matter PM 2.5 and PM 10 pollutants reached levels at least 15 times above the safe limits throughout the city. 

PM pollutants enter the respiratory system to cause medical issues and can even prove fatal in cases of prolonged exposure to dangerous levels.

Those tiny particles called PM2.5 can travel into the lungs and get stuck there posing a serious health risk.

Residents of New Delhi have been advised to remain indoors Monday.

The sources of suspended particulate matter PM 2.5 are as follows: road dust (38 per cent), vehicles (20 per cent), domestic fuel burning (12 per cent) and industrial point sources (11 per cent). 

Reason for making Smog in this Diwali

There are several reasons for the severe Diwali pollution.

1) Delhi's air remains so polluted throughout the year that it does not have room for additional pollution during Diwali.
2) In winter, cooler temperatures and slower winds prevent the smoke from being blown away. Wind speeds were lower for this Diwali than they were for last year's festival.

Note : 

1) Drivers should buy newer cars that has higher emissions standards and carried out several weeks of experimental traffic control, limiting the number of cars on the road. 
2) People should covers their face with a scarf as they rides on the road across NCR area. 
3) The results of Diwali celebrations show that even bursting fewer firecrackers can have deadly results.
4) It is found that popular firecrackers emitted extremely dangerous amounts of particulate matter. 
5) The chemicals used in Chinese firecrackers are more toxic compared to Indian fireworks. Even illegally imported Chinese crackers contain higher sulphur and potassium chlorate content and thus causing more pollution.

Consideration : 

1) The weather did not help matters this year. Higher pressure and calmer winds led to sinking air, keeping the pollutants trapped near the surface. These conditions are especially common during autumn and winter in northern India.
2) India already has the world's highest rate of death from respiratory disease.
3) Almost 60-70 per cent of the smoke during Diwali came from the firecrackers.
4) Before Diwali, the many environmentalists had warned of the possibility of diseases ranging from cancer to imbalance of hormones due to the carcinogenic elements in the smoke emitted by fireworks.
5) PM2.5 particles and droplets are considered to be the most harmful kind of air pollution because they are fine enough to evade the body’s natural filters, penetrate the lungs and enter the bloodstream.
6) Air pollution related issues can hurt “Brand India” in World.

Health Advise during Toxic Smog 

1) Those with heart or lung disease, older adults and children should stay indoors and keep activity levels low during toxic smog in Delhi.
2) Short-term exposure can trigger coughing and eye and throat irritation, while longer term exposure is strongly associated with reduced lung function, heart disease and lung cancer. 

Residents of NCR area are angry about higher than usual levels of smog the morning after Diwali celebrations. (2016)

This year ranking the capital as the 11th most polluted city out of 3,000 cities in 103 countries in terms of fine particulate matter or PM 2.5 and at the 25th place in terms of PM 10 levels

The Delhi government has decided to install large outdoor air purifiers and mist sprinklers at five highly polluted locations in the city.
