This book was released on 2022-02-24 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the role that bioremediation can play in the detoxification of soil, water, and air to improve environmental and human health, with a specific focus on heavy metals and radionuclides. Environmental pollution, whether by natural or human causes, with industrial activities being a key player, is a challenge facing all nations across the world. While treatment has typically required the use of expensive technology, one promising solution is the use of phytoremediation, in which plants act by metabolizing or sequestering pollutants. This eco-friendly solution is a good alternative to the standard methods of soil and water treatments. This book provides not only the basic definitions and classification of technologies used for contaminant remediation but also the most recent studies dealing with the selection of new promising microbial stains and plant varieties involved in the treatment of radioactive and heavy metal contaminants. It provides a detailed description of the biochemical mechanisms and genes involved in the bioremediation of radionuclides and heavy metals, offering a clear insight for academics and practitioners interested in in vitro and in situ biological treatment. This book will be of great value to students and scholars interested in environmental pollution and environmental health from across a range of different disciplines, including environmental microbiology and chemistry, ecology and environmental science, biological and environmental engineering and biotechnology.

Download or read book Use of Humic Substances to Remediate Polluted Environments From Theory to Practice written by Irina V. Perminova and published by Springer Science & Business Media. This book was released on 2006-04-07 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective remediation of polluted environments is a priority in both Eastern and Western countries. In the U.S. and Europe, remediation costs generally exceed the net economic value of the land. As a result, scientists and engineers on both sides of the Atlantic have aggressively tried to develop novel technologies to meet regulatory standards at a fraction of the costs. In situ remediation shows considerable promise from both technical and economic perspectives. In situ technologies that deploy natural attenuating agents such as humic substances (HS) may be even more cost effective. Numerous studies have shown humics capable of altering both the chemical and the physical speciation of the ecotoxicants and in turn attenuate potential adverse environmental repercussions. Furthermore, the reserves of inexpensive humic materials are immense. Which suggests HS portend great promise as inexpensive amendments to mitigate the environmental impacts of ecotoxicants and as active agents in remediation. To elucidate emerging concepts of humics-based remediation technologies, we organized the NATO Advanced Research Workshop (ARW), entitled "Use of humates to remediate polluted environments: from theory to practice", held on September 23-29, 2002 in Zvenigorod, Russia (see the web-site http://www.mgumus.chem.msu.ru/arw).

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.
