UNIMAX Environmental Chemistry for M.Sc. Chemistry by Dr Shafila
Navigate the complexities of our planet’s chemical systems with UNIMAX Environmental Chemistry, a definitive book meticulously crafted for postgraduate students. Authored by Dr. Shafila and published by Unimax Publications, this book serves as an essential guide for M.Sc. Chemistry (2nd Year, Semester System) students, aligning perfectly with the updated UGC module and the academic standards of Panjab University, Chandigarh, and its affiliated colleges. It is a comprehensive resource designed not just for exam success, but for building a robust foundation in the intellectual and practical skills required in this critical field.
This volume provides a structured and in-depth exploration of environmental chemistry, systematically broken down into four key units. The content seamlessly integrates theoretical principles with real-world applications, ensuring students grasp the chemical processes governing our environment and the challenges it faces.
Unit I: Foundations and Toxicology establishes the core concepts. It begins with a detailed examination of the environment, including the composition and vertical temperature profile of the atmosphere, the Earth’s heat budget, and atmospheric stability. The crucial biogeochemical cycles of carbon, nitrogen, phosphorus, sulphur, and oxygen are explained, alongside the biodistribution of elements. The unit then transitions into environmental toxicology, discussing chemical solutions to environmental problems, the principles of biodegradability and decomposition, and a critical analysis of major industrial disasters like the Bhopal gas tragedy, Chernobyl, and Three Mile Island, providing poignant lessons on the consequences of industrial mismanagement.
Unit II: Industrial Pollution and Soil Chemistry tackles the pressing issue of waste and land contamination. It offers a thorough analysis of industrial pollution from key sectors, including cement, sugar, distilleries, drugs, paper, thermal and nuclear power plants, and metallurgy. The unit covers radionuclide analysis, waste disposal and management strategies, and a study of the Minamata disaster. Furthermore, it delves into the chemistry of soils, covering their composition, the role of micro- and macronutrients, and the critical topic of soil pollution from fertilisers, pesticides, plastics, and metals, alongside methods for waste treatment.
Unit III: The Hydrosphere is dedicated to the chemistry of water. It begins by detailing the chemical composition of various water bodies—lakes, streams, rivers, and wetlands—and the hydrological cycle. A significant portion is devoted to aquatic pollution, covering inorganic and organic pollutants, pesticides, agricultural and industrial runoff, sewage, detergents, and oil spills. The unit is particularly strong on practical applications, providing a detailed guide to water quality parameters such as dissolved oxygen (DO), biochemical oxygen demand (BOD), and the presence of metals, chloride, sulphate, phosphate, and nitrate. It concludes with essential water quality standards and analytical methods for measuring BOD, COD, fluoride, oils, and heavy metals (like As, Cd, Cr, Hg, Pb, and Se), as well as water purification and treatment processes.
Unit IV: The Atmosphere focuses on the gaseous envelope that sustains life. It explores the chemical composition of the atmosphere, including the formation and role of particles, ions, and radicals. Students will gain a deep understanding of chemical and photochemical reactions, the formation of smog, and the behaviour of oxides of nitrogen and sulphur. The unit provides a thorough scientific explanation of some of the most pressing global issues: the role of chlorofluorocarbons (CFCs) in ozone depletion, the mechanisms behind the greenhouse effect and global warming, and the chemistry of acid rain. It concludes with a practical overview of air pollution control technologies and the analytical methods and continuous monitoring instruments used to measure air pollutants.
With its unit-wise arrangement, focus on both conceptual clarity and practical analytical methods, and direct alignment with the latest syllabus, UNIMAX Environmental Chemistry is an indispensable companion for any M.Sc. Chemistry student aiming to excel in their examinations and contribute meaningfully to the field of environmental science.
