air pollution

As rapidly-expanding Guwahati, northeast India’s largest metropolis, gears up to clean its air under the National Clean Air Policy (NCAP), a study suggests a cocktail of natural and man-made pollutants wafting through the air is tinkering with the city’s rainwater quality. Guwahati in Assam is among the 122 ‘non-attainment’ cities identified for implementing mitigation actions under the national policy, which means it does not meet the National Ambient Air Quality Standards. Researchers said pinpointing critical sources of air pollution and their contributions to the problem are essential to crafting effective city and region-specific air pollution control plans. Connecting the dots between the origin of…

On 7th September 2017, a 7-year-old school-going child was run over by a school bus while he was trying to cross Old Madras road (OMR). He was rushed to the hospital in an auto-rickshaw. The doctors examined the boy, and proclaimed that he suffered severe head injuries and had died on the way to the hospital. On 14th March 2017, a male pedestrian, 45, was hit and run by an unknown vehicle near Battarahalli junction on OMR when he tried to cross the road. He too sustained serious injuries and died on the way to the hospital. In another three…

Air pollution is now the leading cause of death in India. It accounts for 1.2 million deaths, more than the number of people killed by malaria, smoking or road accidents. Last year, a study by the Central Pollution Control Board (CPCB) found that Bengaluru topped the list of major polluting cities in India. More recently, measurements of pollution level using hand-held devices show that particulate matter pollution levels in many places in Bengaluru are substantially higher than the levels in Beijing, China and yes, even New Delhi.  More alarmingly, pollution levels in Bengaluru are expected to skyrocket over the next…

Since schools have reopened, children, who are more at risk from air pollution, have been facing high levels of exposure. Air Quality Index (AQI), measured by monitors across the city, show that air quality is often poor. For example, on June 5th, the AQI at BTM Layout was 159, which falls in the 'unhealthy' category. At this air quality, children and the elderly, as well as people with lung and heart diseases, may have discomfort breathing. Anti-pollution masks can help reduce exposure to pollutants and minimise health impacts. Here is an overview of different types of anti-pollutant masks, and tips…

‘Beat Air Pollution’ is the rallying call issued by China, which is hosting this year’s World Environment Day celebrations.  And China knows how to beat air pollution, for it has worked hard the past two decades doing just that. According to a report released this March by the Beijing Municipal Ecology and Environment Bureau, 20 years of tough action has produced the following results: “the average concentrations of sulfur dioxide, nitrogen dioxide, and fine particle PM10 dropped by 93.3, 37.8 and 55.3 percent respectively in Beijing. The PM 2.5 content in the air reduced by over 40 percent.” United Nations…

Raj Kumar Jena resides in a slum close to Noapara metro station at Baranagar in Kolkata. Standing on the narrow viaduct below the station he watches several trains chugging into the last station of metro connectivity in the northern fringes of the city. Under the cemented viaduct, flows the Bagjola drainage canal carrying blackish water full of household waste and emitting a putrid smell. Jena however does not look to be as hit by the smell as you would expect him to be. Perhaps, because he lives with it. More than the polluted canal, he says, the unbearable stench from…

Hop, skip, jump or dance—follow any of these strategies and you may be able to navigate across Bengaluru’s footpaths! The Constitution of India guarantees its citizens the right to move freely throughout the territory of India. However, in cities like ours, enjoying that right seems to require a motor vehicle! As a pedestrian, you may be knocked down as soon as you start your journey. The National Urban Transport Policy, formulated in 2014, calls for “universal accessibility” and transport services for all including children, the aged and disabled. It goes on to say, “Walking is a zero-emission mode of transport…

Election manifestos released recently by the BJP, Congress and CPI(M) seem to show some responsibility towards the declining environmental standards of the country. The Congress manifesto, for instance describes air pollution as a “national public health emergency”. The BJP manifesto promised to reduce pollution levels by at least 35% over the next five years in 102 cities. However, past experience shows that the promises made on paper remain largely unimplemented. Few elected representatives seem committed to improve air quality in their respective cities and constituencies. A recent report by Climate Trends titled, “Political Leaders Position and Action on Air Quality…

To address the looming air pollution crisis in Bengaluru, Health & Environment Alliance (HEAL), a leading European non-profit organisation, in collaboration with Global Climate and Health Alliance (GCHA), launched the Healthy Air Coalition on Friday, 5th April, at the St John’s Research Institute (SJRI). SJRI is a key partner of the initiative. According to a study published in the environment journal Lancet Planetary Health, air pollution in India leads to at least 1.2 million premature deaths each year. The 2018 study attributed one in eight deaths that occurred in India in 2017 to poor air quality and exposure to ultra-fine…

This article is part of a special series: Air Quality in our Cities If you were to go walking in Nagavarpalya area in the city, and take the inner by-lanes ahead of Gopalan Mall, you would come upon a sprawling settlement, home primarily to migrant workers from Northern Karnataka. They stay in small makeshift structures that are covered with blue tarpaulin sheets. Such settlements are present in several parts of the city, and they are usually devoid of basic facilities of sanitation, adequate supply of water, electricity etc. "If the migrant workers are staying with their families, they usually cook inside…
