Davos: India’s has the worst air pollution in the entire world, beating China, Pakistan, Nepal and Bangladesh, according to a study released during this year’s World Economic Forum in Davos.
Of 132 countries whose environments were surveyed, India ranks dead last in the ‘Air (effects on human health)’ ranking. The annual study, the Environmental Performance Index, is conducted and written by environmental research centres at Yale and Columbia universities with assistance from dozens of outside scientists. The study uses satellite data to measure air pollution concentrations.
India’s high levels of fine particulate matter (a subject we’ve been looking at on India Ink, albeit just in Delhi) are one of the major factors contributing to the country’s abysmal air quality. Levels of so-called PM 2.5, for the 2.5 micron size of the particulates, are nearly five times the threshold where they become unsafe for human beings.
Particulate matter is one of the leading causes of acute lower respiratory infections and cancer. The World Health Organization found that Acute Respiratory Infections were one of the most common causes of deaths in children under 5 in India, and contributed to 13% of in-patient deaths in paediatric wards in India.
When it comes to overall environment, India ranked among the world’s “Worst Performers,” at No 125 out of the 132 nations, beating only Kuwait, Yemen, South Africa, Kazakhstan, Uzbekistan, Turkmenistan and Iraq. Neighbouring Pakistan, in contrast, ranked 120th and Bangladesh was listed as No. 115 on overall environment.
It is not just India’s big cities which are grappling with air pollution, said Anumita Roychowdhury, Executive Director of India’s Centre for Science and Environment, a non-profit organization which was not involved in the study. Air pollution also is worsening in smaller cities, she said.
The main culprit, Ms Roychowdhury said, is the growing number of vehicles in India. While the country still has far fewer vehicles per capita than developed nations, India’s cars are more polluting, Ms Roychowdhury said. Other air pollution experts also cite India’s reliance coal and polluting industries like brick-making that are located close to densely-populated areas.
Emission standards are nearly “10 years behind European standards,” Ms Roychowdhury said, and these standards are not legally enforceable, unlike in countries like the United States which has the Clean Air Act. India has an Air (Prevention and Control of Pollution) Act, 1981 which is supposed to be enforced by the Central Pollution Control Board. This act lacks teeth, Ms Roychowdhury said. “We need to take big steps or the problem will overwhelm us,” she said.
D Saha, a scientist in the “Air Lab” at India’s Central Pollution Control Board said the study’s findings were not a matter of huge concern.
“We should not compare our country with others,” Dr Saha said. “India has a different terrain.” He cited seasonal rainfall, deserts and dusty conditions as being responsible for the particulate matter. “Can we put water sprinklers across the country?,” he asked.
Particulate matter comes from boilers, thermal power plants and cars, as well, he said, but India would not have development if these activities were curbed, he said. “The diseases mentioned in the report are caused by many factors not just particulate matter, we are raising undue alarm,” Mr Saha said.
His advice? “It is a non-issue, we have other pressing problems like poverty, focus on them.”
Several species of beautiful birds have been forced into leaving the Garhi Mandu city forest area due to rise in pollution and loss of habitat. The forest area is spread over 894 acres in northeast Delhi.
Locals and civic workers are dumping debris and plastic waste in a huge natural wetland, which borders as much as 60 per cent of the south and eastern boundaries of this protected forest. Regular burning of garbage is causing severe air and water pollution.
On the filled up land, vegetable cultivation has also started. Water from the wetland is being regularly pumped out for cleaning vehicles and cultivation. Regular fishing is also disturbing the habitat and food chain of thes birds by causing the wetland to dry up. Open thoroughfare and playgrounds around the wetlands have also disturbed nesting.
“Resident waterbirds scared away so far include oriental darter, spot-bill duck, great and little cormorant, cinnamon bittern, white-throated kingfisher, purple swamphen, Indian moorhen,” said ecologist TK Roy. Birds, whose nesting has been disturbed, include green bee-eater, bank mynah, dabchik, and blackwinged still.
“The wetland attracts several species but despite repeated requests from environmentalists, the government is yet to notify the wetland. That’s why it’s unprotected and officially not part of the city forest,” he said.
“While so much money is being spent to save wetlands, a natural one along this city forest has been left neglected. Once the wetland is notified by the government for its protection, Garhi Mandu City Forest will be combined forest land of terrestrial and wetland habitats,” he said. The city forest is rich in biodiversity. The first-ever bird count at Garhi Mandu, conducted on February 24 this year, found 90 species, including 26 migratory and several threatened birds. “We found 33 species of waterbirds, including 13 migratory ones. Of the 57 species of terrestrial birds, 13 were migratory,” said Roy, who conducted the count.
The city forest shares its eastern boundary with colonies such as Shastri Park, Jagjit Nagar and Usmanpur along the Pushta Road which branches off National Highway 24. On the other side, it borders the left bank of the Yamuna.
Air pollution is now the fifth largest killer in India, says newly released findings of Global Burden of Disease report
- Findings released by the scientists behind the study at a Dialogue Workshop organised by Centre for Science and Environment, Indian Council of Medical Research and US-based Health Effects Institute
- Annual premature deaths caused by particulate air pollution have increased by six times since the year 2000
- With one fifth of global deaths, India shows the greatest impacts of outdoor air pollution
- Globally, air pollution-related deaths have increased by 300 per cent since 2000. About 65 per cent of these deaths occur in Asia
- CSE’s national air quality analysis shows half of urban population breathes air with particulate levels that exceed the permissible limit. One third of urban Indians live in critically polluted areas
CSE’s health survey in Delhi shows majority of Delhiites say air pollution has worsened and blame rising number of vehicles for it
New Delhi, February 13, 2013: Outdoor air pollution has become the fifth largest killer in India after high blood pressure, indoor air pollution, tobacco smoking, and poor nutrition – says a new set of findings of the Global Burden of Disease report. The India and South Asia-specific findings were officially released here today at a Dialogue Workshop jointly organised by Centre for Science and Environment (CSE), Indian Council of Medical Research and the US-based Health Effects Institute.
The Global Burden of Disease (GBD) report is a world-wide initiative involving the World Health Organization which tracks deaths and illnesses from all causes across the world every 10 years. The new findings were released by Aaron Cohen, principal epidemiologist of the Health Effects Institute and co-chair of the GBD Ambient Air Pollution Expert Group.
The report says that in 2010, about 620,000 premature deaths occured in India from air pollution-related diseases. GBD has ranked air pollution as one of the top 10 killers in the world, and the sixth most dangerous killer in South Asia. In fact, particulate air pollution is now just three places behind indoor air pollution, which is the second highest killer in India. “This is a shocking and deeply disturbing news. This calls for urgent and aggressive action to protect public health,” said Sunita Narain, director general, CSE.
Among the others who attended the release and participated in the discussions were Kesav Desiraju, secretary, Union ministry of health and family welfare; Sanjiv Kumar, environment secretary of Delhi; Vinod Raina, head, Department of Medical Oncology, AIIMS; SK Chhabra, head, Department of Cardiorespiratory Physiology, Vallabhbhai Patel Chest Institute; Randeep Guleria, head, Department of Pulmonary Medicine, AIIMS; Sanjeev Bagai, CMD, Nephron Clinic and Health Care; and Professor Kalpana Balakrishnan of the Sri Ramchandra Medical College and Research Institute.
Daniel Greenbaum, president and Robert O Keefe, vice president, Health Effects Institute, also shared the findings of the GBD assessment.
The India-specific analysis has been done using estimates of air pollution exposure at the national level and incidence of leading causes of deaths, aided by ground-level measurements, satellite remote sensing and models to capture population exposure. The GBD assessment follows a rigorous scientific process involving over 450 global experts and partner institutions including the Institute of Health Metrics and Evaluation, the WHO, the Health Effects Institute, the University of Queensland, Australia, Johns Hopkins University, and Harvard University.
The key new findings — India
- Shocking increase in Indian death toll: Air pollution is the fifth leading cause of death in India, with 620,000 premature deaths in 2010. This is up from 100,000 in 2000 – a six-fold increase.
- Massive loss in healthy years: Air pollution is the seventh leading cause behind the loss of about 18 million healthy years of life due to illness. It comes after indoor air pollution, tobacco smoking, high blood pressure, childhood underweight, low nutritional status, and alcohol use.
- Respiratory and cardiovascular diseases key reasons for air pollution-induced premature deaths: These diseases include stroke (25.48%), chronic obstructive pulmonary disease (17.32%), Ischemic heart disease (48.6%), lower respiratory infections (6.4%), and trachea, bronchus and lung cancer (2.02%).
The key findings – South Asia and the world
- Increase in death toll: Air pollution related diseases cause 3.2 million deaths worldwide every year. This has increased from 800,000, last estimated by GBD in the year 2000 – a whopping 300 per cent increase. About 74 million healthy life years are lost annually.
- Ranked among the top 10 killers in the world: In South Asia, air pollution has been ranked just below blood pressure, tobacco smoking, indoor air pollution, poor intake of fruits and diabetes. Everyone – rich and poor – is vulnerable.
- Two-thirds of the death burden from outdoor air pollution occurs in developing Asia: In 2010, particulate air pollution in Asia led to over 2.1 million premature deaths and 52 million years of healthy life lost, which is two-thirds of the worldwide burden. Killer outdoor air contributes to 1.2 million deaths in East Asia where economic growth and motorization are taking over, and 712,000 deaths in South Asia (including India) which is at the take-off stage. This is much higher than the combined toll of 400,000 in EU 27, Eastern Europe, and Russia.
CSE analysis exposes severe air pollution trends in India
In the wake of the GBD findings, CSE has analysed the latest air quality data available from the Central Pollution Control Board for the year 2010. Of the 180 cities monitored for SO2, NO2 and PM10, only two — Malapuram and Pathanamthitta in Kerala — meet the criteria of low pollution (50% below the standard) for all air pollutants.
Trends in polluted cities
- Close to half the cities are reeling under severe particulate pollution while newer pollutants like nitrogen oxides, ozone and air toxics are worsening the public health challenge.
- Vulnerable urban population: Half of the urban population breathes air laced with particulate pollution that has exceeded the standards. As much as one third of the population is exposed to critical levels of particulate pollution. Smaller and more obscure cities are amongst the most polluted.
- More cities in grip of PM10: About 78% cities (141) exceed the PM10 standard. 90 cities have critical levels of PM10; 26 have the most critical levels, exceeding the standard by over three times. Gwalior, West Singhbhum, Ghaziabad, Raipur, and Delhi are the top five critically polluted cities.
- More cities in grip of NO2: About 10% of the cities (19) exceed the NO2 standard. Of these, about nine have critical levels. Howrah, Barrackpore, Badlapur, Ulhasnagar and Asansol are the top five critically polluted cities.
- State of SO2 pollution: One city — Lote in Maharashtra — exceeds the SO2 standard. Moderate levels of SO2 are noted in Jamshedpur and Saraikela Kharsawan in Jharkhand; Chandrapur, Badlapur, Ulhasnagar, and Pune in Maharashtra; Ghaziabad and Khurja in UP, Dehradun in Uttarakhand and Marmagao and Curchorem in Goa.
- Cities with double-trouble — particulates and NO2: Howrah, Barrackpore, Asansol, Durgapur, Sankrail, Raniganj, Kolkata (West Bengal), Badlapur and Ulhasnagar (Maharashtra) have critical levels of NO2 and PM10. Delhi, Haldia, Bicholim, Jamshedpur, Meerut, Noida, Saraikela Kharsawan, Jalgaon and Raipur have high levels of NO2 as well as critical levels of PM10.
- Worsening trend since 2005: The PM10 monitoring network has doubled between 2005 and 2010 from 96 to 180 cities. During this period the cities with low level of pollution have fallen from 10 to 2, while the number of critically polluted cities has increased from 49 to 89. In 2005 about 75% of the cities exceeded the standard. In 2010, 78% are exceeding the standard. NO2 monitoring has expanded from 100 cities in 2005 to 177 in 2010. In 2005 only one city had exceeded the standard for NO2; in 2010, 19 cities have exceeded the standard. The tightening of the national ambient air quality standards has also changed the air quality profile of the cities.
- Stabilisation in some cities: Some mega cities that have initiated some pollution control action in recent years have witnessed either stabilisation or some decrease in the levels.
CSE survey captures angst and worries of Delhiites
CSE has carried out a rapid survey of citizens of Delhi on their perception of air pollution and health and the mitigation strategies. This has exposed overwhelming popular concern about air pollution.
- The majority of respondents — about 64% — have said air pollution is worsening.
- 79% have attributed the problem of air pollution to growing number of vehicles.
- 74% have said that air pollution causes respiratory problems and respiratory symptoms have increased in frequency in the last two months. About 14% say this has increased school absenteeism amongst children
- Close to half have said that their doctors have mentioned air pollution as one of the causal factors.
- Close to one third of the respondents have said that they are aware of the new GBD estimates.
- About 26% know that the World Health Organisation and International Agency on Cancer Research have reclassified diesel emission as a class 1 carcinogen, putting it in the same class as tobacco smoking for its strong link with lung cancer.
- There is strong support for improvement in public transport, walking and cycling. About 47% have supported reduction in car numbers. About 62% have said there should be restraint on diesel cars and SUVs.
Says Anumita Roychowdhury, CSE’s executive director-research and advocacy and head of its air pollution team: “Days of doubts and complacency are over. There is hard evidence now to act urgently to reduce the public health risks to all, particularly children, elderly, and poor. No one can escape toxic air. India will have to take aggressive action to reverse the trend of short-term respiratory and cardiac effects as well as long-term cancer and other metabolic and cellular effects. Remember – toxic effects like cancer surface after a long latency period. Therefore, exposure to air pollution will have to be reduced today to reduce the burden of dieses.”
What should India do:
- Make National Ambient Air Quality Standards legally binding in all regions: The national air quality planning and city action plans need a roadmap for each source of pollution and aggressive measures. Impose penalty on cities if air quality standards are violated.
- Prepare stringent vehicle technology and fuel quality roadmap, encourage in-use vehicle management: It is shocking that the terms of reference of the new committee that has been set up to propose the next Auto Fuel Policy Roadmap does not even include public health in its agenda. Make urgent timelines for Euro V and Euro VI emissions standards. Restrain dieselization.
- Control and cut increase in vehicle numbers by scaling up public transport, non-motorised transport, compact city planning and car restraint measures.
- Strengthen implementation plans for critically polluted notified areas
- Account for health cost in decision making: Valuation of acute and chronic illnesses must be linked to decision on air pollution control measures.
- Put in place a public information system on daily air quality with health advisories and implement smog alert and pollution emergencies measures.

In our day-to-day activities, we actually release substantial amount of toxic substances into the environment.
Have you ever think about the shampoo, soap and cleaning detergent that you use. Many of them contain chemicals that are washed down the sinks and pipes, into drains, rivers, reservoirs or even the sea.
Think about the fast-food lunch you had. In the process of producing the bread, meat patty and salad for the burger, chemicals in the form of pesticides, man-made fertilizers and even hormones are released into the lands, water and air. The wrappers used in packaging the meal is bound for the landfills and incinerators (because it is very hard to recycle them). In turn, harmful gases are released when the wrappers (as well as other waste) are buried or burnt.
Think about the car that you drive to work, or even the bus or cab that you take to your office. These vehicles emit greenhouse gases (contributing to global warming) and toxic substances like lead (harmful to living things, including the human body) into the atmosphere.
And we have yet to reach the part on the amount of chemicals and poisonous gases produced by factories and industries, in the process of manufacturing the various items we use (eg. electronics, clothes, paper and plastic products, furniture, packaged food etc), or extracting energy resources (eg. oil, coal, etc) from the earth.
In our modern day life, it may be hard to leave zero trace of toxic substances, or create zero pollution in our activities. So many of the things that we use on a daily basis contain some form of chemicals, or are produced through the use of some chemicals. Despite the pollution caused, we would still need to travel to work, whether by private or public transport. And we definitely need to consume food.
GREEN SOLUTION. GET GREEN.
Consider switching to more natural cleaners and personal products, such as natural detergents, or organic detergents, as well as organic shampoos and lotions. Made of natural substances instead of man-made chemicals, minimal harmful chemicals are used in the process of their production. At the same time, these natural products are ready bio-degradable and do little harm even when released into the environment, because they are found in the natural environment in the first place.
Switch to organically grown food if you can. Organically grown food is grown without the use of synthetic pesticides and fertilizers that would harm the environment, as well as hormones or genetic re-engineering. What’s more, organically grown food are so much healthier, because they are free of carcinogens and heavy metals (as a result of the synthetic chemicals), as well as more nutritious. And keep away from fast-food!
Also, what does going green mean in practice is to drive less, and use the public transport instead. You can even opt for carpool service in case the option is available. Automobiles are one of the single largest sources of air pollution on earth today, and the harmful gases released contribute to global warming and climate changes. By taking public transport (such as buses and trains), you are actually helping to reduce the number of automobiles on this earth, and hence the amount of air pollution produced by these vehicles.
Open burning of leaves, which has for ages been pretty much the norm for getting rid of fallen leaves in winter, has come under the scanner of pollution watchdogs for releasing huge amounts of soot, harmful particles and toxic gases aggravating air pollution. Sweepers and gardeners in public parks have been found burning leaves in large heaps. They have been doing this for years as a habit. Notices are served to civic bodies and other agencies too.
Traditionally, burning of leaves in the winter has been an integral part of the maintenance of parks in the city, in order to prevent the huge heaps of dry leaves from adding to the municipal solid waste stream.
But what makes this a huge problem is that there around 3,700 ornamental parks, almost 10,000 ordinary/neighbourhood parks and about 80 children’s parks across Delhi. “So the amount of leaves that burn in winter is just enormous. They are usually burnt in the mornings, mostly filling the area with smoke and soot,” he said.
The Central Pollution Control Board (CPCB), in its soon-to-be published Source Apportionment Study, which pinpoints the sources and the amount of each air pollution component, has mentioned burning of leaves as a source of winter pollution in Delhi and elsewhere.
That apart, burning of leaves and woods also release the cancer-causing organic compound called benzene and toxic gas carbon monoxide in large amounts, said Dr T.K. Joshi of Centre for Environment and Occupational Health at Maulana Azad Medical College. “Small children are at graver risk. Joggers and all who inhale more air in the morning are also greatly exposed to it,” he said.
A UN report had recently called Delhi one of the most polluted Asian metropolises.
Burning leaves also adds to the formation of thick smog in winters.
