GE6351 ENVIRONMENTAL SCIENCE AND ENGINEERING L T  P C 3   0  0 3
OBJECTIVES:
To the study of nature and the facts about environment.
To  finding  and  implementing  scientific,  technological,  economic  and  political  solutions  to environmental problems.
•           To study the interrelationship between living organism and environment.
•           To appreciate the importance of environment by assessing its impact on the human world;
envision the surrounding environment, its functions and its value.

To study the dynamic processes and understand the features of the earth’s interior and surface.
To study the integrated themes and biodiversity, natural resources, pollution control and waste management.

UNIT I             ENVIRONMENT, ECOSYSTEMS AND BIODIVERSITY                                   12
Definition,  scope  and  importance  of  Risk  and  hazards;  Chemical  hazards,  Physical  hazards, Biological hazards in the environment – concept   of an ecosystem – structure and function of an ecosystem – producers, consumers and decomposers-Oxygen cycle and Nitrogen cycle – energy flow in the ecosystem – ecological succession processes – Introduction, types, characteristic features, structure and function of the (a) forest ecosystem (b) grassland ecosystem (c) desert ecosystem (d) aquatic ecosystems (ponds, streams, lakes, rivers, oceans, estuaries) – Introduction to biodiversity definition: genetic, species and ecosystem diversity – biogeographical classification of India – value of biodiversity:  consumptive  use,  productive  use,  social,  ethical,  aesthetic  and  option  values  – Biodiversity at global, national and local levels – India as a mega-diversity nation – hot-spots of biodiversity – threats to biodiversity: habitat loss, poaching of wildlife, man-wildlife conflicts – endangered and endemic species of India – conservation of biodiversity: In-situ and ex-situ conservation  of  biodiversity.  Field  study of  common  plants,  insects, birds  Field  study of  simple ecosystems – pond, river, hill slopes, etc.

UNIT II            ENVIRONMENTAL POLLUTION                                                                        10
Definition – causes, effects and control measures of: (a) Air pollution (Atmospheric chemistry- Chemical composition of the atmosphere; Chemical and photochemical reactions in the atmosphere - formation of smog, PAN, acid rain, oxygen and ozone chemistry;- Mitigation procedures- Control of particulate and gaseous  emission, Control of SO2, NOX, CO and HC) (b) Water pollution : Physical and chemical properties of terrestrial and marine water and their environmental significance; Water quality parameters – physical, chemical and biological; absorption of heavy metals - Water treatment processes. (c) Soil pollution - soil waste management: causes, effects and control measures of municipal solid wastes – (d) Marine pollution (e) Noise pollution (f) Thermal pollution (g) Nuclear hazards–role of an individual in prevention of pollution – pollution case studies – Field study of local polluted site – Urban / Rural / Industrial / Agricultural.

UNIT III           NATURAL RESOURCES                                                                                        10
Forest resources: Use and over-exploitation, deforestation, case studies- timber extraction, mining, dams and their effects on forests and tribal people – Water resources: Use and overutilization of surface and ground water, dams-benefits and problems – Mineral resources: Use and exploitation, environmental effects of extracting and using mineral resources, case studies – Food resources: World food problems, changes caused by agriculture and overgrazing, effects of modern agriculture, fertilizer-pesticide problems, water logging, salinity, case studies – Energy resources: Growing energy needs, renewable and non renewable energy sources, use of alternate energy sources. Energy Conversion processes – Biogas – production and uses, anaerobic digestion; case studies – Land resources: Land as a resource, land degradation, man induced landslides, soil erosion and desertification – role of an individual in conservation of natural resources – Equitable use of resources for sustainable lifestyles. Introduction to Environmental Biochemistry: Proteins –Biochemical degradation of pollutants, Bioconversion of pollutants. Field study of local area to document environmental assets – river / forest / grassland / hill / mountain.

UNIT IV           SOCIAL ISSUES AND THE ENVIRONMENT                                                       7
From unsustainable to sustainable development – urban problems related to energy – water conservation, rain water harvesting, watershed management –  resettlement and  rehabilitation of people; its problems and concerns, case studies – role of non-governmental organization- environmental ethics: Issues and possible solutions –  12  Principles of  green  chemistry- nuclear

OUTCOMES:

TOTAL : 45 PERIODS

Environmental Pollution or  problems  cannot  be solved  by  mere  laws. Public  participation  is an important  aspect  which  serves  the environmental  Protection.  One  will  obtain  knowledge  on  the following after completing the course.
•         Public awareness of environmental is at infant stage.
•         Ignorance and incomplete knowledge has lead to misconceptions
•         Development and improvement in std. of living has lead to serious environmental disasters
