Course Name : Aquatic Pollution

Code(Credit) : FSEM 3207 (1-1-0)

Course Objectives

  • To collect wastewater from residences, industries, institutions, and so on,
  • To find a place to discharge the wastewater (usually the nearest water course is chosen, but wastewater could also be used for groundwater recharge or even recycled to water supply),
  • To remove water pollutants that would produce adverse impacts to the receiving water or adversely affect the health of people subsequently using the water and
  • To do all the above in a cost - effective manner.

Learning Outcomes

  • Understand chemistry involved in environment
  • Identify the chemical reactions and changes in contaminants
  • Understand the microbiology and its usefulness to environment
  • Perform experimental analysis of some properties of water ad wastewater

Course Syllabus

  • Theory
    Introduction to aquatic pollution, the sources of pollutants, toxic organic compounds and their impacts in the aquatic organisms and the abiotic environment, Classification of pollution- physical, chemical and biological classification of water pollution- description of terminologies. Sewage and domestic wastes- composition and pollution effects- sewage treatment and its reuse.
    Agricultural wastes- organic detritus, nutrients, Adverse effects of oxygen demanding wastes: importance of dissolved oxygen; Oxygen demand; BOD; COD; Oxygen budget;
    Biological effects of organic matter.
  • Excessive plant nutrients: Eutrophication; Red tides and fish kills. Pesticide types and categories; inorganic pesticides, Organo-chlorine compounds, Organo-phosphorous compounds; Polychlorinated biphenyls (PCBs); Bioaccumulation and impact on aquatic fauna and human health; toxicology. Heavy metals: Interaction of heavy metals with water and aquatic organisms. Bioremediation and Phytoremediation. Oil pollution; Crude oil and its fractions; Sources of oil pollution; Treatment of oil spills at sea; Beach Cleaning; Toxicity of Petroleum Hydrocarbons; Ecological Impact of Oil pollution- Case studies. Microbial pollution: Types of aquatic microbes; autotrophs and heterotrophs; saprotrophs and necrotrophs; Sewage Fungus Complex; Transmission of Human Pathogenic Organisms; Zoonosis; Development of Antibiotic Resistance and its impact; Biofilms and Biocorrosion; Radioactivity and background radiation of earth: Radionuclide polluting, special effects of radioactive pollution. Thermal pollution and its effects, Physical and chemical nature of possible effluents from major industries in India. Monitoring and control of pollution: Biological indicators of pollution. Solid waste management.
