Breathless during Diwali? Blame it on smoke from sparklers

PUNE: Common firecrackers like sparklers and flower pots are less noisy, but owe their special effects to the heavy metal content in them which are not just harmful to the environment, but when inhaled cause health problems. Noisy crackers do not have heavy metal content.
Inhaling the oxides of heavy metals can cause 'oxidant stress,' which is the baseline for asthma, bronchitis, pneumonia and lung cancer. Children and elderly people are more vulnerable. The cold weather aggravates the problem, as it remains stagnant in the air for a longer time, he added.
A test conducted by NGO Awaaz Foundation recently showed that of the 17 firecrackers had heavy metal content, only three had the details on their cover boxes. Most manufacturers do not mention the chemical content and the few who do list it, do it inaccurately.
Firecrackers with heavy metal content were found in four colour sparklers, multicolour pots, green flowerpots, red flowerpots, mirinda sparkler, vulcano rassi bombs, electric crackers, musical mala, star plus sparklers, shooting star, pink sparklers, seven shots, crackling king, green rassi bomb, aerial out, golden cherry and blue rain.
Sumaira Abdulali, convenor of Awaaz Foundation, told TOI that all firecrackers tested are available in the market but the content is not mentioned on the covers. "Only a few boxes have the content mentioned but it was either incorrect or not accurate. All these heavy metals have been banned under the hazardous chemicals Act,'' she said.
According to a Supreme Court order, no cracker may exceed 125 decibel and the chemical composition of all crackers must be displayed on the packaging. Petroleum and Explosives Safety Organisation (PESO) is supposed to address some requirements of the Indian fireworks industry like development of environment friendly fireworks, study of nature of chemical composition and contrivance, quality control and quality assurance, testing of raw materials, among others.
Abdulali said,We believe that less noisy firecrackers are safe. But sparklers, anara and multicolour pots, have a maximum content of heavy metals that give the colour. Bombs have less content of heavy metals,'' she said.
Dr Sandeep Salvi, director of Chest Research Foundation, said heavy metals are harmful for the environment and cause health problems. Inhaling the smoke for long can impact one's health. It can affect the kidney, lung system and cause respiratory issues, he said.
When crackers are lit, they produce different oxides of heavy metals that are harmful for lungs and get absorbed into the circulation and affect other organs of the body. It can also get deposited in the brain and kidney,'' he said.
Chest Research Foundation had tested firecrackers and the level of pollutants in Kothrud four years ago and found that sulphur dioxide level in the air was 200 times more that the WHO limit. The level was found to be 5.5 ppm (parts per million), whereas the limit is 0.02 ppm. The oxides of calcium and magnesium in air are very high during Diwali.
Hence, a majority of people complain of respiratory problems. They complain of cough, irritation in the eyes and nose and wheezing. The more smoke one inhales, one is more prone to these health problems,'' said Dr Salvi.
Gufran Beig, senior scientist at Indian Institute of Tropical Meteorology, Pune said heavy metals are highly carcinogenic.

Four-colour sparkler Iron, manganese, chromium, titanium and vanadium
Multi-colour pots Aluminium, copper, iron
Anar red Aluminium, zirconium, zinc, iron
Mirinda sparkler Aluminium, vanadium. manganese, titanium
