Garbage burning can cause cancer, should be banned: Doctors

With leaf litter often set on fire by the roadsides, along with other trash, Bengalureans are getting affected. Children are most vulnerable, and toxins released during burning garbage affect lungs, according to experts.

It happens in every nook and corner of Bengaluru. Electronic City, Basavanagudi, Malleshwaram, Indiranagar. And your area too, possibly. This is the season of burning garbage in Bengaluru.

Last year we wrote about it. This year is no different as these photos prove.

 

What’s different about garbage this season?

From January to April, Bengaluru witnesses scenes of burning garbage. mainly leaf litter.

While trees profusely shed dry leaves this season, there are no local composting or disposal solutions for leaf litter. The BBMP contractors do not like to pick up dry leaves, as they add volume but not weight (Contractors are paid by weight). BBMP pourakarmikas burn leaves as they do not know what to do with them or they are instructed to do so by the contractors, corporators or health inspectors. To make it worse, civic workers leave thin plastic, paper, cloth or bedding while burning leaves, which results in the emission of harmful chemicals.

Bengaluru is a city that is perceived to have the most burning of garbage, out of all Indian metro cities. This was projected in a survey done by The Environment Research Institute (TERI) in 2013.

Burning garbage is not a new trend in Bangalore. An environment audit of municipal solid waste management done by Indian Institute of Science (IISc) in 2006 noticed the burning of garbage in all areas across Bengaluru, and suggested that it should be avoided.

The KSPCB data for January-February 2015 shows that particles in the air, or particulate matter as they are scientifically called, in the city exceed the limit of 100 μg/m3, and exceeds by upto 185% in some areas in the city. Central Silk Board, Victoria Hospital, Graphite India in Whitefield, AMCO Batteries on Mysore Road and others have high amount of particulate matter. Particulate matter comes from smoke from vehicles, dust and smoke, ash and soot from burning garbage.

What do experts say about burning garbage?

When polluted air is inhaled, a part of the particulate matter, or particles as they are commonly known, in the inhaled smoke actually reaches our lungs. Hair follicles in our nose can filter the particles only upto some extent. These particles can cause serious illness to people, especially children and elderly citizens. Medical Director of Rajiv Gandhi Institute of Chest diseases, Dr. Shashidhar Buggi, says that 85% of the airborne particles in the inhaled smoke that comes from burning leaves, reach the lungs.

Once the particles reach the lungs, they remain there for months to years. They cause physical, chemical and cellular changes in the lungs, leading to inflammation, causing increased mucus secretion, bronchospasm (tightening of the muscles around the bronchial tubes) and other effects, which cause cough, wheezing, and other respiratory infections.

Continuous exposure to the smoke emitted by burning leaves, for example, by those who sleep on the sidewalks near such fire, can be fatal or cause a permanent damage, because Carbon Monoxide is produced when the burning is improper. Burning 1,000 kilos of leaves will produce about 56 kilos of Carbon Monoxide. This, if inhaled, enters blood and affects the red blood cells, converting haemoglobin into carboxy-haemoglobin, which reduces its oxygen-carrying capacity.

“Burning of plastic will add to the carcinogenic effects… Dioxins and styrene gases are some of the most dangerous chemicals leading to lung cancer. This should be totally banned.”

Burning of plastic will add to carcinogenic effects. Dioxins and styrene gases are some of the most dangerous chemicals leading to lung cancer. This should be totally banned, says Dr Buggi.  “The most common hydrocarbons are benzo-pyrene and poly hydrocarbons,” he adds.

Children more vulnerable to health problem

Inhaling any kind of smoke, be it from burning leaves, garbage, mosquito coils or camp fires, is injurious to all age groups. However, as children’s lungs are still developing and small in size, their vulnerability is particularly high, says a paediatrician from Malleshwaram, Dr. Kaushik.

“Also, unlike adults, it will not occur to children to move away from the smoke quickly or to cover their noses. This is another reason they are more vulnerable than other age groups,” he says.

Apart from short-term effects like running nose, continuous sneezing, dry skin, scaling of skin and itching, children are also at the risk of developing asthma. Constant exposure to smoke might lead to asthma in a child, and will be carried on to adulthood. A child raised in a highly polluted environment, with exposure to smoke for over ten years, has a much higher predisposal to lung cancer.

Burning piles of leaves, even after removing any plastic and paper from them, is dangerous. Smoke emitted from burning leaves, or from any biodegradable matter, has carbon particles. “But when plastic is mixed, it is not only carbon that is emitted, but also sulphur and lead, both of which are very strong carcinogens,” says Dr Kaushik. However, carcinogenic content in smoke emitted from burning only leaves, is less compared to burning the mixed pile that contains plastic and paper along with leaves, he adds.

85% of the particles that come from burning leaves reach lungs, and remain there for months. The rest 15% is prevented by the hair follicles in the nose.

How to minimise the effect?

As a preventive measure, Dr Buggi suggests covering the nose with handkerchief or with three-layered mask to prevent inhaling these particles.

Regular breathing exercises – Yoga and Pranayama – and nutritional diet will help in controlling the effects to some extent. Dr Buggi says that permanent solution, however, would be a healthy environment. Proper scientific management of domestic waste, encouraging composting of dry waste and simple scientific innovation in waste management can go a long way, says Dr Buggi.

Civic amenities and urban growth: Lessons from a design jam on Bengaluru BBMP Bye-laws

Access to civic amenities like parks is skewed even when they exist as per BBMP bye-laws, finds a representative study of three Bengaluru wards.

In the OpenCity Bengaluru Design Jam on BBMP, our team analysed and debated the bylaws and zoning rules governing civic amenities, parks and open spaces in the city. As a diverse group of spatial thinkers and design creatives, we sought to understand what liveability meant for citizens navigating the urban landscape, and how building and zoning laws address our needs and the city’s densifying future. Urbanisation is transforming cities worldwide, significantly impacting the quality of life both socio-economically and environmentally. In democratic societies, livability crises affect and are affected by the different levels of urban growth and how cities are…

Why all Bengaluru lakes need a biodiversity survey: Lessons from Dorekere

The Dorekere survey highlighted the importance of documenting the biodiversity of lakes and the need to involve the community in such an activity.

A lake is not just a body of water, it is an ecosystem. Action Aid Association India organised a survey to document the biodiversity of Dorekere, a lake in South Bengaluru. The biodiversity survey was funded by the Australian Consulate in Chennai. It not only documented several species but highlighted the importance of such an activity in understanding whether Bengaluru lakes are being developed in an ecologically sound manner. Dorekere is a 28-acre lake in the Uttarahalli suburb of South Bengaluru. The Bruhat Bengaluru Mahanagara Palike (BBMP) currently manages the lake. Earlier, it came under the purview of the Karnataka…
