Environmental Chemistry and Toxicology is an emergent course in Ethiopia. It has great role in mitigating solution for different environmental stresses. All human activities irrespective of the scope and severeness have an impact in soil, air, water and life of the receiving bodies. Thus, the main focus of this book is to study the fate of chemical pollutants in the environment. This book comprises five chapters such as, Introduction to Environmental Chemistry, Aquatic Chemistry and Water pollution, Atmospheric Chemistry and Air pollution, Soil Chemistry and Pollution and Environmental Toxicity and Toxicology. The overall goal of this book is to gain an understanding of the fundamental chemical processes that are central to a range of important Environmental problems and to utilize this knowledge in making critical evaluations of these problems.
Biophysical Chemistry of Fractal Structures and Processes in Environmental Systems
The rapid pace of innovation in nanotechnology has posed a greater risk over health and environment demanding a need for responsible development, relevant policy framework and risk assessment guidelines. This book offers a comprehensive overview of this challenging, inter-disciplinary research area. Topics covered include: Nanotechnology roadmap, Environmental, Ethical and social impacts of nanotechnology The fate and behaviour of nanomaterials in aquatic, terrestrial and atmospheric environments Ecotoxicology and human toxicology of manufactured nanoparticles Occupational health and exposure of nanomaterials Risk assessment and global regulatory and policy responses Environmental Nanotechnology will serve as a valuable resource for students, researchers in nanoscience and nanotechnology, environmental science, chemistry, as well as for scientists in industry, regulators and policy makers.
The studied area (Al-Atwani village) southern east of the Egyptian ferroalloys company is highly polluted with lead, cadmium and cobalt due to the emissions of the company, in addition to exhaust automobile emissions (the highway connects Cairo and Aswan). The degree of pollution is limited as faraway of the company. There are no clinical signs of typical acute or chronic poisoning of lead, cadmium and cobalt, meanwhile animals exposed to sub-toxic concentrations of these metals. Presence of livestock particularly near the company for long time increases the risk of poisoning with metal pollutants. The obtained data from estimation of lead, cadmium in blood, hairs or wool, milk and feces of different animals reared in the vicinity of the company are higher than the international permissible limit.
The main aim of this book is to introduce individuals of all ages to chemistry and to demonstrate the importance of chemistry in daily life. In addition to these intentions, individuals love chemistry with considering such matters as chemistry of housing and households, chemistry in our environment, chemistry of cosmetics, chemistry in foods, nutritional supports, the chemistry of swimming pools, the chemistry of our body, toxicology, chemistry of toxic substances, the entrance and discharge mechanisms of toxic substances to our body.
This major two volume work presents a new decision making tool which enables manufacturers and scientists to undertake life cycle assessment (LCA) of new products from the design and development stages. The methodology allows the environmental consequences of a product to enter into decision making in the same way as traditional commercial parameters such as price, quality etc. Significantly, it is in accordance with international consensus, as defined by SETAC (Society of Environmental Toxicology and Chemistry) and ISO (International Organization for Standardization). Moreover, the individual steps have been made operational through the creation of a collection of tools for assessment. The books are derived from the Environmental Design of Industrial Products (EDIP) programme organized by the Technical University of Denmark and five leading Danish companies. The project was sponsored by the Danish Environmental Protection Agency (EPA) and the Confederation of Danish Industries.
Undoubtedly, there is currently a greater awareness of environmental issues globally. A wave of the environmental consciousness and concern has swept across the developed and developing countries. Chemistry is exciting between the environment and living creature and is going on all around us. Presently, there is an ever increasing demand of such information and knowledge in the form of printed books which address all environmental issues. The present effort is one of them attempting to incorporate information on chemistry of the environment in relation to human beings in a concise manner. In addition to providing updated material in the rapidly developing area of environmental chemistry, this book emphasizes several major concepts that are providing essential to the practice in the area. Besides, the problems such as Freon and the ozone layer, acid rain, types of pollution and toxic effects of various gases and pesticides are also discussed. Although the book is designed for readers who have a good understanding of general chemistry and some knowledge of organic chemistry, it can also serve as resource materials for individuals who may not have a very good background in chemistry.
Chemistry of the Environment, 3rd edition, is a concise, clear and current account of today's environmental issues and the science needed to understand them. It systematically lays out themes of sustainability, atmosphere, hydrosphere, lithosphere and biospheres, while stressing the interconnectedness of environmental problems and solutions. This new edition has been extensively revised to reflect the rapid evolution of all areas of environmental science. Additionally, much of the text and organisation have been refined for enhanced clarity. New worked problems and end of chapter problems have also been included to make this an excellent university textbook.
