Delhi Pollution: It’s all social media is talking about

Social media is abuzz with discussions and opinions on the New Delhi pollution issue, with Twitter chatter being the loudest.
by Meltwater India

Voted as one of the most populated cities in the world for several consecutive years, New Delhi, India’s bustling capital, is facing some serious health risks too. Due to over-population and severe pollution, the city’s atmosphere is often hazy with smoke and fog.

This month, though, the air pollution has reached a point of severity that is out of the ordinary. On Tuesday, The Indian Medical Association (IMA) declared a public health emergency. They have advised schools to be shut, and for the public to avoid walking or running outside, as the air pollution is said to be hazardous.

In November last year, one million school children were forced to stay home from school, thousands of workers reported sick and long queues formed outside shops selling face masks as the Indian capital struggled with its worst pollution level in two decades.

2017 is showing similar degrees of danger, with the Air Quality Index (AQI) sitting on an average level of 400 and reaching over 700 in the early morning and during most afternoons. To put it in perspective, anything over 100 is considered dangerous, and 500 is the maximum AQI level. This means that even healthy people are at a high risk of developing serious respiratory problems.

Meltwater, the global leader in media intelligence, took to the (virtual) streets to listen to what the public is saying on social media about the health emergency.

Mapping the chatter

In a week, since November 1, the terms “New Delhi” and “pollution” have appeared together 1,965 times on online editorial media in India alone, and has received 2, 339 mentions across social media.

92% of the mentions were from Twitter, where the sentiment was 50% negative (only 2% positive and the rest neutral). “Risk,” “dangerous” and “health” were among the most used words when discussing the New Delhi pollution problem. Some citizens spoke about having a “scratchy throat” and “sore eyes” specifically since Diwali, held this year on 19 October.

“Runners” was also a hot topic being spoken about across social media platforms with 177 mentions this week.

The India Medical Association urged the iconic New Delhi Half Marathon, due to take place on 19 November, to be called off in order to protect runners, marshals and spectators from exposure to the thin and low-quality air. With even healthy people being warned not to walk outdoors, it’s been advised that it would be too dangerous to allow the runners to over-exert themselves, and urged the race to be cancelled for the safety of all.

Today, social media is an opportunity to gauge public opinion and sentiment. Meltwater believes that companies and individuals can benefit from these insights to better understand needs, contextualise them and then to improve company strategy.

This refers to a wide range of possibilities. IMA is an example of how governments can use social insights as a guide to making more informed decisions. Event sponsorships is an example of how companies can use this data for better, more informed decisions to benefit the public.

Media intelligence lets companies, organisations or individuals use social insights to gather external data to make better internal decisions. There is an abundance of data out there, and millions of online conversations happening at any given minute. Meltwater helps you to make sense of it all.

You’re so polluted, Bandra!

…but Sion and Worli, not much. MPCB readings for one month show rising trend of air pollution and particulate matter.

If you’re in Bandra, you should probably not breathe till you get the hell out of there. You’re not much better off elsewhere in the city, but Bandra is the worst.

For the Maharashtra Pollution Control Board’s (MBCB) findings for air quality in Bandra for the period September 21, 2012 to October 19, 2012 are not just startling, they will literally take your breath away. As per the MPCB’s daily findings for its station at Government Polytechnic (Kherwadi), Bandra, the suburb has been breathing very polluted air for 18 days out of the 28 days of recent monitoring.

You don’t have to take the MPCB’s word on air pollution in the city alone – an environmental status report for Mumbai was recently released by the Brihanmumbai Municipal Corporation (BMC); the report’s findings were similar to those of the MPCB.

What constitutes air pollution? As per the MPCB, there are three parameters for measuring air pollution – sulphur dioxide (SO2), oxides of Nitrogen (NOx) and RSPMs, or Respirable Suspended Particulate Matter. This last, if it exceeds the permissible level of 100 µg/m3, gives rise to such respiratory disorders as asthma or bronchitis.

The RSPM levels for Bandra in the period monitored have been above 100 µg/m3 for the most part. The average reading for Bandra is 111.61 µg/m3; the highest has been 176 µg/m3 on September 30, while the lowest has been 60 µg/m3 on October 10.

The corresponding sulphur dioxide and nitrous oxide levels, however, have been within the permissible range of 80 µg/m3 for Bandra throughout the monitoring period.

Meanwhile, though Sion has recorded below permissible levels of RSPMs, exceeding it only thrice in the monitoring period, the levels of nitrous oxide have been higher than the permissible levels, throughout. Experts cite city-wide construction activities and rising vehicular traffic for the rise in air pollution levels. All recorded levels of pollutants at Worli are below the permissible levels.

The areas that the MPCB monitoring stations are present in the city and the state are chosen for high traffic density, industrial growth, human population and its distribution, emission source, public  complaints if any and the land use pattern.
