Impact of nefarious Air Pollution!

Image
Poor air quality has a direct effect on human health. Exposure to air pollutants or airborne allergens can harm our respiratory and cardiovascular systems or exacerbate existing conditions in susceptible populations. Children, older adults, persons with asthma, and immune compromised persons are most vulnerable to air quality impacts. Respiratory impacts can include advanced-stage asthma, respiratory allergies, and airway diseases, while cardiovascular effects can include hypertension, coronary artery disease, heart attack, and stroke. Bad air quality is also linked to eye problems up to and including partial blindness, skin allergies, lack of mental alertness, and kidney problems due to inhalation of chemical particles that are bad for kidney health. The national library of medicine at the National Centre for Biotechnology Information in the United States has published a detailed report on each particulate element in polluted air and its effect on people. The  same report  va...

Understanding GRAP!!

Image
With air pollution remaining critically high and serious health since 2010 in India, especially in the capital city of New Delhi, the Supreme Court of India in 2015 mandated the Central Pollution Control Board (CPCB) to draw up an urgent and comprehensive action plan to tackle this problem. The action plan was mapped out by an expert committee and submitted to the Supreme Court in December 2016. After proper analysis and deliberation, it was accepted and rolled out, thus introducing the Graded Response Action Plan or GRAP to the city of Delhi and the National Capital Region. Implemented in January 2017 by the Ministry of Environment, Forest and Climate Change, this plan aimed to ensure the “prevention, control, and abatement” of air pollution in Delhi-NCR. The central government set up the Commission for Air Quality Management (CAQM) to implement the program. This statutory body was tasked to work with other Indian states to develop and implement similar plans for a more considerab...

The Silent Killer - World’s Most Polluted City

Image
  In 2014, The World Health Organization studied the air quality of 1,600 cities in 91 countries. New Delhi, India, was ranked number 1 as the most polluted city in the world. Beyond the findings for Delhi, 13 of the top 20 cities with the highest annual averages of PM2.5 in the WHO study were also in India. The figures were alarming and concerning!   Using satellite-based remote sensing technology and ground-level data from the Central Pollution Control Board, Dr. Michael Greenstone and his team from WHO produced an insightful study (Greenstone et al., 2015) showing that 660 million people (more than half of India’s population at that time) lived in areas that highly exceed India’s standards for fine particulate pollution. Large portions of India, particularly in the north along the Indo-Gangetic plain, were heavily polluted and in non-compliance with India’s National Air Quality Standards (NAAQS.) Since 2014, this data has been updated yearly by the W.H.O. Though New Del...
