Download or read book Recent Advances Towards Improved Phytoremediation of Heavy Metal Pollution written by David W.M. Leung and published by Bentham Science Publishers. This book was released on 2013-11-08 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy metal pollution represents a global challenge to both public health and environmental sustainability. Any means to reduce heavy metal pollution in the environment is of considerable economic significance. The use of green plants to clean up heavy metal pollution is an environmentally friendly as well as a low-cost approach to the problem. This plant-based biotechnology is commonly known as ‘phytoremediation’. Presently, there is limited application of this technology because useful plants with enhanced heavy metal resistance/tolerance are still needed to assist remediation of environments polluted with heavy metals. A key to improved phytoremediation of heavy metal pollution lies in research seeking for a better understanding of the mechanism(s) of heavy metal resistance/tolerance in plants. This E-book presents a unique treatment of the topics that have never been comprehensively brought together before in a single advanced reference. The volume explores aspects of plant biology that are critical for employing phytoremedation techniques to combat heavy metal contamination such as the specific plant biology, seed biology, plant tissue culture and enzymology. This E-book will be a useful reference to plant biologists, biotechnologists and environmental engineers seeking information about phytoremediation of heavy metals from the environment.
Download or read book Heavy Metal Pollution and Its Phytoremediation Through Wetland Plants written by Prabhat Kumar Rai and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrialisation and urbanisation have led to the rapid deterioration in the water quality of rivers, lakes and reservoirs. Heavy metal pollution in aquatic ecosystems has become the most important point for discussion in recent years. The problem of heavy metal pollution is emerging as a matter of concern at local, regional and also at global scales. Heavy metal pollution in aquatic ecosystems pose serious threats to aquatic biodiversity, and drinking of contaminated water pose severe health hazards in humans. Therefore, the focus of attention has been shifted from mere monitoring of environmental conditions to the development of alternative means to solve the environmental problems at local and global levels. This new book discusses how economic aspects and side effects of conventional treatment technologies in aquatic ecosystems paved way to phytoremediation technology.
Download or read book Detoxification of Heavy Metals written by Irena Sherameti and published by Springer Science & Business Media. This book was released on 2011-09-01 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy metals are severe environmental pollutants, and many of them are toxic even at very low concentrations. With industrial development, soil pollution with heavy metal elements have dramatically increased. The uptake of heavy metals via plants that are exposed to contaminated soils is a risk for human health and a major hazard for the ecosystem as a whole, including soil microorganisms. On the other hand, plants may be used in the decontamination of soils. The topics presented in this book include: sources of heavy metals contaminants in soils; plant species that can grow on contaminated soils; the phytoremediation of contaminated soils; tolerance, accumulation and detoxification mechanisms of zinc, copper, arsenic, cadmium and vanadium in plants; the critical role of sulfur metabolism in heavy metal tolerance; the role of aquatic macrophytes, plant growth-promoting bacteria, sugar crops and earthworms in detoxification; and heavy metal stabilization by promoting zeolite synthesis in soils.

Download or read book Phytoremediation of Heavy Metals from Industrial Effluent by Aquatic Plants written by Dr. Rita N. Kumar and published by Google Book Publishers. This book was released on with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water and land are precious natural resources for the agricultural activities, which are prerequisite for any civilization. Rapid industrialization and urbanization exploit and severely pollute these resources. The organic and inorganic pollutants generate an unfavourable environment for the survival of aquatic flora and fauna by affecting the aquatic ecosystems. The increasing urbanization, industrial revolution, advancement of technologies, etc. are the reasons for increased pollution level. Smoke and dust particles pollute the air, solid waste pollutes the land, and in the same way industrial discharge, municipal sewage, and domestic wastewater pollute the water resources (streams, lakes, oceans, groundwater). Heavy metals naturally occur within the earth’s crust but presently due to several manmade activities, they pool-up at certain places and hamper the natural constitution and function of natural resources they invade. The natural sources of heavy metal intrusion are weathering of minerals, volcanic eruptions, overexploitation of underground resources, etc., which cause heavy metals of underlying rocks to leach into the groundwater, whereas man-made sources are smelting, mining, industries, sludge selling, agricultural use of serious metals in fertilizers and pesticides and many more. Some of the heavy metals like Lead, Mercury, Arsenic, and Chromium are one of the culprits for global warming and destroying the atmospheric ozone with atmospheric methane, nitrous oxide and sulphur dioxide. Environmental contamination by heavy metals is a serious problem throughout the world. The addition of toxic heavy metals in the ecosystem may lead to its bioaccumulation, geo-accumulation, and biomagnification. The heavy metals can be removed by using some common conventional treatment processes. Physicochemical removal processes such as adsorption, ion exchange, membrane filtration, reverse osmosis etc. are used to remove heavy metals. Biological treatments using microorganisms include methods such as activated sludge, trickling filters, stabilization ponds etc. Biosorption and phytoremediation are promising, low cost, eco-friendly best solution for removal of heavy metals. The phytoremediation applications can be classified based on contaminant fate: degradation, extraction, containment or combination of these. Phytoremediation applications can be classified based on mechanisms involved. Such mechanisms include extraction of contaminant from soil or groundwater; concentration of contaminants in plant tissue, degradation of contaminants by various biotic and abiotic processes; volatilization or transpiration of volatile contaminants from plants into air, immobilization of contaminants in root zone etc. The present book Phytoremediation of Heavy Metals from Industrial Effluent by Aquatic Plants focuses on preliminary screening of aquatic macrophytes having phytoremediation potential, selection of two specific hyperaccumulator species for phytoremediation, screening of heavy metals accumulation potential and biochemical constituents of selected plant species involving heavy metal treatment, assessing heavy metal accumulation potential, physio-chemical and phytochemical parameters with a treatment of electroplating industry effluent, measuring the phytoremediation efficiency of two selected plant species by in situ experiments, assessing the physico-chemical characteristics of contaminated water treated with two selected plant species, and heavy metal accumulation in biomass by both the species. The book would be a ready reference guide for pollution control board authorities, industry managers, and remediation specialists, to prevent the further degradation and deterioration of contaminated sites using remediator plant species for retaining inviolability for pliant sustainability.
Download or read book China s Water Pollution Problems written by Claudio Delang and published by Routledge. This book was released on 2016-03-31 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water pollution is one of the most serious problems plaguing China today with millions of citizens drinking water unfit for consumption. These abysmal conditions have fuelled increasing social discontent, as people become more concerned by the need to address the pressing issues of water pollution, scarcity, and waste management. This book describes how and why China has ended up in such a dire situation, what the government is doing to address the problem and the difficulties encountered in attempting to reduce pollution. The analysis is based on both gray literature (newspaper articles, NGO reports, Chinese government information) and on academic studies. The gray literature gives a voice to those who suffer from the pollution, their advocates, and government officers, and allows the reader to better grasp the conditions on the ground, and the impact of the air pollution among the people in different areas in China. The academic literature adds a theoretical perspective and brings these different case studies into a broader context. This book will be of great interest to students of environmental pollution and contemporary Chinese studies looking for an introduction to the topic, as well as researchers looking for an analysis of China's environmental problems.

Download or read book Phytoremediation of Heavy Metals from Wastewater and Polluted Soil written by Isaiah Debrah and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most developing countries, there is dependence on wastewater for vegetable production due to limited access to clean water. Heavy metal pollution of aqueous streams, soil and sediments is a major environmental problem globally. Methods such as ion exchange, chemical and microbiological precipitation that have been developed to remove heavy metals have limited access due to the cost involved, labour and energy. This book, therefore unveils the phytoremediation potentials of Lactuca sativa, Brassica oleracea L. var capitata and Daucus carrota var sativa irrigated with wastewater from Nagodi mining site in Ghana. The concentration of heavy metals in the soil and the wastewater was also analysed. Differential accumulation and translocation of copper, lead, iron, manganese, cadmium and zinc in the root, stem and leaf of the vegetables were investigated during the experiment. This book should serve as a guide to environmentalists, scientists and all who may be interested in using plants for clean-up of toxic metals and also helps to understand the mechanisms plants uses to remove heavy metals from our environment in order to guarantee a greener and cleaner planet for all of us.

Download or read book Plant ABC Transporters written by Markus Geisler and published by Springer. This book was released on 2014-09-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the fascinating superfamily of plant ATP-binding cassette (ABC) transporters and their variety of transported substrates. It highlights their exciting biological functions, covering aspects ranging from cellular detoxification, through development, to symbiosis and defense. Moreover, it also includes a number of chapters that center on ABC transporters from non-Arabidopsis species. ABC proteins are ubiquitous, membrane-intrinsic transporters that catalyze the primary (ATP-dependent) movement of their substrates through biological membranes. Initially identified as an essential aspect of a vacuolar detoxification process, genetic work in the last decade has revealed an unexpectedly diverse variety of ABC transporter substrates, which include not only xenobiotic conjugates, but also heavy metals, lipids, terpenoids, lignols, alkaloids and organic acids. The discovery that members of the ABCB and ABCG family are involved in the movement of phytohormones has further sparked their exploration and provided a new understanding of the whole family. Accordingly, the trafficking, regulation and structure-function of ABCB-type auxin transporters are especially emphasized in this book.
