India's capital Delhi has the dubious distinction of being the world's most polluted city and Diwali fireworks are making its air pollution even worse. The smog will be particularly dangerous on Nov. 12 and 13, with the concentration of pollution-related particles — PM2.5 and PM10 — projected to increase by 148% and 170% respectively, according to
Indian media reports.
News headlines said US President Obama's 3 day visit to New Delhi last year cut his life expectancy by 6 hours. Why? Because Delhi has the highest level of the airborne particulate matter, PM2.5 considered most harmful to health, with 153 micrograms per cubic meter, 15 times higher than the 10 micrograms per cubic meter considered safe by the World Health Organization (WHO).
Delhi is not alone; Other cities in India claim
13 spots among the top 20 dirties cities in the world. Not far behind Delhi's 153 micrograms is another Indian city, Patna with 149 micrograms. Other Indian cities among the world's dirtiest are: Agra (88 ug/m3), Allahabad (88 ug/m3), Ahmedabad (100 ug/m3), Amritsar (92 ug/m3), Firozabad (96 ug/m3), Gwalior (144 ug/m3), Khanna (88 ug/m3), Kanpur (93 ug/m3), Lucknow (96 ug/m3), Ludhiana (91 ug/m3) and Raipur (134 ug/m3). Pakistani cities of Karachi (117 ug/m3), Peshawar (111 ug/m3) and Rawalpindi (107 ug/m3) also count among the world's most polluted.
India's
pollution problems are not entirely due to poorly controlled industry and transport. The early winter problems are significantly exacerbated by the burning of the fields by farmers after harvest.
With a score of
just 3.73 out of 100, India ranks as the worst country for the
ill effects of toxic air pollution on human health among 132 nations, according to a
report presented at the World Economic Forum 2012. India's neighbors also score poorly for toxic air pollution, but still significantly better than India. For example China scores 19.7, followed by
Pakistan (18.76), Nepal (18.01) and Bangladesh (13.66).

In the overall rankings based on 22 policy indicators, India finds itself ranked at 125 among the bottom ten environmental laggards such as Yemen, South Africa, Turkmenistan, Uzbekistan and Iraq while
Pakistan ranks slightly better at 120. The indicators used for this ranking are in ten major policy categories including air and water pollution, climate change, boidiversity, and forest management.
These rankings are part of a joint Yale-Columbia study to index the nations of the world in terms of their overall environmental performance. The
Yale Center for Environmental Law and Policy and
Columbia's Center for International Earth Science Information Network have brought out the Environment Performance Index rankings every two years since 2006.
The Yale-Columbia study confirms that environmental problems in South Asia are growing rapidly. The increasing consumption by rapidly
growing population is depleting natural resources, and straining the environment and the infrastructure like never before. Soil erosion, deforestation, rapid industrialization, urbanization, and land and water degradation are all contributing to it.
It's important to remember that
Bhopal still remains the worst recorded industrial accident in the history of mankind. As India, Pakistan and other developing nations vie for foreign direct investments by multi-national companies seeking to set up industries to lower their production costs and increase their profits, the lessons of Bhopal must not be forgotten.
It is the responsibility of the governments of the developing countries to legislate carefully and enforce strict environmental and safety standards to protect their people by reversing the rapidly unfolding environmental degradation. Public interest groups, NGOs and environmental and labor activists must press the politicians and the bureaucrats for policies to protect the people against the growing environmental hazards stemming from growing consumption and increasing global footprint of large industrial conglomerates.
There will be severe health consequences for all Indians unless the Modi government acts to legislate and regulate various sources of pollution in the country. Pakistan government, too, needs to act to prevent severe harm to public health by rising pollution.
