ENVIRONMENTAL STUDIES FOR UNDERGRADUATE COURSES
Authors: Dr. Sushmitha Baskar & Dr. R. Baskar
This book Environmental Studies for Undergraduate Courses follows the syllabus for undergraduate courses of higher education. The book has been divided into eight units. The first unit covers definition, scope and importance of environmental studies. Second unit explains the renewal and non-renewal resources. Next unit introduces the reader to the types of ecosystems, and food chains. Fourth unit describes biodiversity and its conservation.
The fifth unit elaborates sources of pollution, solid waste management, and disaster management. Sixth unit discusses sustainable development, urban problems, climate & global warming, and legislative environmental Acts. Human welfare and environment form the next unit. Fieldwork relating to study of simple ecosystems forms the eighth and the last unit.
The salient features of the book include a simple explanation of the subject, relevant case studies, environmental quotes and interesting facts.

Some classic case studies: Air pollution
1. Taj Mahal, Agra, India: A symbol of love affected by air pollutants
Emperor Shah Jahan constructed this historic monument in the memory of his wife Mumtaz Mahal at Agra, India in the year 1648. The innumerable industries in and around Agra released a large amount of sulphur dioxides, suspended particulate matter, smoke, soot etc causing tanning, blackening, and yellowing of the marble stone. The oxides reacting with rainwater resulted in acid precipitation and in return caused the deterioration and corrosion of the Taj Mahal. In 1984, the Supreme Court of India ordered designated polluting industries in the Taj area to be shut down and or adopt cleaner control technologies.
2.The London smog of 1952: A classic air pollution case study
During the cold month of December, the people of London burnt large amounts of coal for heating their homes, which resulted in a huge amount of smoke, soot, ash, sulphur oxides etc. generated from the chimneys. On 5 December 1952, the temperature went down to -1°C and the humidity at 80%. There was a thick fog and the air near the ground was moist.The accumulation of smoke close to the ground was so much that the sunlight was totally cut off and the air stayed cool and static. The term smog means fog that has soot in it. Average smoke measurements in London showed the PM concentration was 56 times the level normally experienced and the sulphur dioxide level increased by 7 times
(700 ppb). Around 4000 people died due to the smog causing pneumonia, bronchitis, tuberculosis, heart failure, asphyxiation, chest pains, inflammation of the lungs, damage to respiratory cells, permanent lung damage, respiratory ailments, susceptibility to cancers etc. The effects on vegetation were profound due to the resulting acidic rain. Following this disastrous event, London formulated the Clean Air Act, 1956 and all the traditional coal fires were converted to heaters fueled by gas, steam, hot water, oil, smokeless coal and electricity.
3.The terrible Bhopal Gas tragedy of India, 1984
Another classic case study involving air pollution is one of World’s worst industrial disasters, which occurred on December 3, 1984 in Bhopal, Madhya Pradesh (India). The Union Carbide Company used methyl isocyanate in manufacturing Carbaryl (carbamate) pesticides. On the fatal day none of the safety devices worked and there was a functional failure of the vent scrubber outlet. There was a violent chemical reaction in the tank and the pressure built up. This popped the safety valve open. The safety valve remained open for more than two hours. As a result over 30 – 40 tons of methyl isocyanate (MIC) and 35 – 40 kg phosgene were emitted into the atmosphere. The gas spread over the entire region and city, air being the medium. Approximately 5000 people died in the disaster. More than 2,50,000 people were exposed to the gas. MIC afflicts the lungs, eyes, skin, respiratory system, gastrointestinal system etc. The clean up of the tragedy cost approximately 570 million U.S. dollars compared to the cost of the safety devices, which would have cost only 1 million U.S. dollars if it had been installed before the tragedy. The after effects of the Bhopal gas tragedy are seen even today with people and children having genetic disorders.
