SENIOR SCIENTIST in the Forest Pathology Division at the Forest Research Institute (FRI) AN Shukla said that satellite pictures had shown “Asian Brown Haze” over Delhi.
He was delivering a lecture on the second day of the two-day national workshop on ‘Aerosols and its impact on climate with special reference to Indo-Gangetic plains’ at the Indian Institute of Technology-Kanpur (IIT-K) here on Saturday.
Shukla said that this phenomenon had extended to the entire stretch of lower Himalayas including West Bengal, Bangladesh and other South Asian countries.
He said that about 200 scientists who had studied the new phenomenon as part of “Indian Ocean Experiment”(INDONEX) for about six years since 1995 had named it “Asian Brown Haze”.
The experiment under the United Nations Environment Programme (UNEP) found that three-kilometre deep pollution blanket has been disrupting climate patterns across Asia and beyond. Emission of green house gases principally carbon dioxide and methane from transport, power plants and industries were believed to be heating up the atmosphere, leading to disruption in climate patterns.
He said a lethal mix of traditional village practices such as burning of agriculture waste, fossil fuels in vehicles and in new industries was creating a blanket around the earth, restricting re-radiation, trapping heat and causing global warming.
AK Gosain of IIT-Delhi said that on account of severity of droughts and intensity of floods, green house gases (GHG) in the Ganga river basin would further deteriorate. His assessment was based on a research “Vulnerability assessment of climate change impact on Indian water resources-Ganga basin study” conducted by him.
A team of doctors from the Laxmipat Singhania Institute of Cardiology at Kippur has found that about 400 patients implanted with permanent pacemakers and living in the Indo-Gangetic region are suffering after consuming polluted drinking water and adulterated mustard oil.
The team including Dr M Ahmad, Adnaik R Arjun, J Rajgopal, RPS Bharadwaj, RK Bansal, CM Varma, Ramesh Thakur and G Goyal studied the patients for possible etiology and clinical profile of degenerative complete heart block.
These doctors said that while they found non-degenerative causes were not present, diabetes and hypertension were seen in 28 per cent and 46 per cent cases, respectively.
