According to the World Health Organisation (WHO) global air pollution database released in Geneva, India has 14 out of the 15 most polluted cities in the world in terms of PM 2.5 concentrations -- the worst being Kanpur with a PM 2.5 concentration of 173 micrograms per cubic metre, followed by Faridabad, Varanasi and Gaya.

On Trending @ 10, another grim reminder that the air that we are breathing in several of our cities in India is killing us. The World Health Organisation, in its latest report, shows that of the 20 most polluted cities in the world, the top 14 are in India. The rider is that the numbers are from 2016. On the show, we look at the startling findings of the report and ask: are steps taken by the government to combat air pollution enough? How can India's air be cleaned? And what can we learn from the China model?

Transportation is a major source of air pollution in many countries around the world due to the high number of vehicles on the roads. Vehicles introduce toxic materials into the atmosphere that have several bad effects on human health and the ecosystem. Examples of such pollutants include Carbon monoxide, Hydrogen, Nitrogen Oxide, particulate matter, Ammonia and Sulphur Dioxide.

India's top environmentalist Sunita Narain speaks about what she would do if she was the environment minister, and why she thinks the government, institutions, big companies and citizens need to do more to save the environment.

As north India goes through another day of 'severe' air pollution, we take a step back and look at this environmental disaster not just from the prism of the political slanging match but also from a saner perspective. What can we do to deal with this apocalyptic situation now beyond knee-jerk solutions like a half-hearted odd-even scheme?

A new report from the Centre for Science and Environment shows that lifestyle diseases or non-communicable diseases are responsible for more than 61 per cent of all deaths in India. Whether it is heart diseases, respiratory illnesses, cancer, obesity or food allergies, new research reveals that the rise in their incidences is due to factors such as rapid urbanisation, air pollution and changes in diet rather than in our genes. The new report called Body Burden: Lifestyle Diseases is essentially a report card on the state of health in India.

Delhi may be the worst polluted city in the world but not all is Delhi's fault. The neighbouring areas of Delhi, that is, Haryana, Punjab, Ghaziabad and Noida holds many industrial areas that emit poisonous gases every single which then accumulates in Delhi's atmosphere. So, Delhi will never be rid of its pollution crisis unless the governing bodies of these so-called neighbours regulate the industries emitting poisonous gases.

Delhi and the National Capital Region is in a state of emergency. With the Air Quality Index at the `Severe’ level people are confronting that hard truth about toxic air - it’s hazardous to health and life.

आज सुबह से दिल्ली NCR धुंध और smog की मोटी चादर से ढंका हुआ है. आँखों में जलन सांस लेने में परेशानी ये इसके असर हैं. दिल्ली में लगातार जहरीली हवा का प्रकोप बना हुआ है और pm स्तर 2.5 है.

कारण सबको पता है मगर समाधान में किसी की गहरी दिलचस्पी नहीं है. सभी को लगता है कि ये नवंबर की बात है, उसके बाद सब सामान्य हो जाएगा. दिल्ली की हवा आपकी जेब और हेल्थ पर असर डालने फिर से आ गई है. कब तक दिल्ली बात-बात में स्कूल बंद करती रहेगी, वो यह क्यों नहीं कहती कि शहर में डीज़ल कारों का पंजीकरण बंद हो, कारों की संख्या में बेतहाशा वृद्धि बंद हो, पब्लिक ट्रांसपोर्ट की संस्कृति को बढ़ाने के लिए कारें बंद करने की बात नहीं होती, कब तक बड़ों के फैलाए इस प्रदूषण का समाधान हम बच्चों के स्कूल को बंद करके करेंगे.
