Available in PDF, EPUB and Kindle. Book excerpt: Measured metals concentrations in roadside soil samples. Most vehicle-associated metals (including copper) were found in the top 15 centimeters of soil. Lead, zinc, and copper concentrations were closely correlated - in contrast to concentrations of nickel and chromium, which were not associated with each other nor with the first three metals. Sequential extraction of the samples by a method similar to that of Tessier (to identify the potential environmental availability of the metals) found that somewhat less than half of the copper was extracted before the "residual" extraction. Most of the extracted copper was in the "organically bound" and "carbonate bound" fractions. Separately, an "exchangeable" fraction was measured by suspending roadway soil samples overnight in an ammonium acetate solution; this extracted about 7% of the copper.

This book was released on 2012-07 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental pollution of soil, plants and deposits around highways endanger urban environment through heavy metals as the byproducts of vehicles and urban industries along with other pollutants.Due to a slow traffic movement and long stops, tires undergo comparatively more abrasion due to repeated brakes and this intensifies, zinc discharge and lead releases from automobile fuels, all of which are being factors that increase the metal contents of runoffs of roads.The transport pathways and effects of these heavy metals depend on arrange of physical and chemical properties including pollutant concentration, the size spectrum of heavy metal containing particles and the chemical form in which the metals occur.In the present study we have seen the effects of heavy metals on roadside soil quality and plant nutrition in Agra District (The City of TAJ MAHAL). The values of the heavy metals have been compared with results found by other investigators in various countries worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: With more than 50% of the world’s population already living in towns and cities, migration from rural areas continuing at an alarming rate in developing countries and suburbanisation using more and more land in developed countries, the urban environment has become supremely important with regard to human health and wellbeing. For centuries, urbanisation has caused relatively low level soil conta- nation mainly by various wastes. However, from the time of the Industrial Revolution onwards, both the scale of urban development and the degree of soil contamination rapidly increased and involved an ever widening spectrum of c- taminants. With constraints on the supply of land for new urban development in many countries, it is becoming increasingly necessary to re-use previously dev- oped (brownfield) sites and to deal with their accompanying suites of contaminants. It is therefore essential to fully understand the diversity and properties of urban soils, to assess the possible risks from the contaminants they contain and devise ways of cleaning up sites and/or minimizing hazards. The author, Helmut Meuser, is Professor of Soil Protection and Soil Clean-up at the University of Applied Sciences, Osnabrück and is one of Europe’s foremost experts on contamination from technogenic materials in urban soils. He has many years’ experience of research in Berlin, Essen, Osnabrück, other regions of Germany, and several other countries.

Download or read book Heavy Metal Contamination of Soils written by Irena Sherameti and published by Springer. This book was released on 2015-04-06 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following a description of the various sources and factors influencing the contents of heavy metal pollution in post-catastrophic and agricultural soils, subsequent chapters examine soil enzymes and eggs as bio-monitors, lead adsorption, the effects of arsenic on microbial diversity, and the effects of Mediterranean grasslands on abandoned mines. A third section focuses on the adaptation strategies used by plants and bacteria, such as Pinus sylvestris in industrial areas, and the rhizosphere in contaminated tropical soils and soil treated with sewage sludge. Further topics addressed include strategies of bioremediation, e.g. using transgenic plants as tools for soil remediation. This new volume on heavy metals in soil will be of interest to researchers and scholars in microbial and plant biotechnology, agriculture, the environmental sciences and soil ecology.
Download or read book On Heavy Metal Pollution from a Suburban Road Network written by Sudip Kumar Pal and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of urban diffuse pollution a suburban road acts as a potential source of toxic pollutants among which heavy metals are very common, are found at elevated concentrations and are generally persistent. With a lack of detailed understanding of metal emission patterns on suburban roads, a detailed study is therefore essential for gaining an improved understanding to plug the knowledge gap in terms of urban diffuse pollution management. The present understanding of pollutant build-up and wash-off processes on road surfaces elucidates that these processes are highly site specific and are hard to generalise in certain aspects. Therefore, this study aimed to characterise heavy metal emissions and associated pollution levels at several road sites on the Riccarton Campus road network using road sediment collected during dry and wet weather periods. The heavy metal concentrations of Cd, Cr, Cu, Ni, Pb and Zn, are believed to be greatly toxic and are highly abundant in road traffic environments, were determined by strong nitric acid digestion and atomic absorption spectrometry. The study revealed that the pollutant build-up and wash-off processes were site specific and so also were the derived local build-up and wash-off parameters, as expected. However, these derived parameters were very different from those used in common urban drainage models suggesting that the default values are (significantly) inappropriate for the studied road network. The quantification of heavy metals in road sediments displayed significantly higher concentrations than local background concentrations. Their concentrations between weather types were found in the order of runoff, snow and dry road sediment, and also varied between sampling sites according to site-specific attributes, such as road lay-out inured traffic movement pattern, road surface condition and presence of road paint rather than due to traffic volume alone. The concentrations of all metals except Pb were significantly higher in finer sediment sizes than in larger sediment sizes. Correlation analyses revealed a similar pattern showing a greater number of statistically significant associations between metals in finer sediment sizes. An assessment of heavy metal contamination indicated that road sediment may likely pose a moderate to considerable level of ecological risk, if transported to the nearby water environment in the study area. The assimilation of the knowledge gained in this study should help to improve current understanding of environmental pollution from suburban roads and to provide better guidance for selecting appropriate control measures under the framework of sustainable urban drainage systems.
Download or read book The Heavy Elements written by J. E. Fergusson and published by Pergamon. This book was released on 1990 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text provides a broad survey of the ten heavier elements of the p-block, which have a number of features in common as well as displaying periodic trends. Full comprehension of the chemistry of the elements is necessary before complete understanding of environmental and health effects is possible. In many texts, however, basic chemistry is avoided as too complex or uninteresting. The author's approach in this case is to use the disciplines of health and environmental science to enhance understanding of the chemistry and to provide students with an integrated approach to the influence of the elements on the world. Information is provided on concentrations, sources and speciation of the heavy elements and their effects on the health of human beings. The text is intended to stimulate students to investigate further aspects of the heavy elements, and contribute to this young but rapidly growing field.
Download or read book Highway and Urban Environment written by Sébastien Rauch and published by Springer Science & Business Media. This book was released on 2009-12-02 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 9th Highway and Urban Environment Symposium (9HUES) was held in Madrid, Spain, from 9-11 June 2008. HUES is run by Chalmers University of Technology within the Alliance for Global Sustainability (The AGS). HUES was initiated by Professor Ron Hamilton at Middlesex Polytechnic (now University) in the early 1980s and had the title "Highway Pollution". The initial aim was to measure and assess challenges in highway pollution, with a strong emphasis on urban photochemical smog, ozone formation and particle release. After the first symposium, the emphasis on air pollution issues continued through to Munich in 1989 where diesel particulate issues and the relevance to health through measurements of PM10 emerged. The focus on air quality issues was also strengthened. In parallel, the symposium started to receive an increasing number of scientific contributions from the area of urban run off, indeed to the extent that the title of the symposium was changed to "Highway and Urban Pollution". Since then the importance of science in support of policy became increasingly important as a key aspect of the symposium. 9HUES was held at TRANSyT- Universidad Politécnica de Madrid, Spain to provide a professional and scientific forum on global examples of the science required to support pathways to a positive and sustainable future in the highway and urban environment.

Download or read book Heavy Metal Toxicity Environmental Concerns Remediation and Opportunities written by Rajeev Pratap Singh and published by Springer Nature. This book was released on 2023-10-24 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume covers a comprehensive account of the sources, toxic biological as well as environmental impacts, and possible remediation strategies for contamination by heavy metals. In biological systems, toxic metals affect the integrity of cellular organelles and act as carcinogens causing chromosomal aberrations or as systemic toxicants leading to cardiovascular, neurobehavioral, and immunological disorders. In plants, they interfere with photosynthesis, fertility, metabolite, and chlorophyll synthesis. Toxicity induced by heavy metals involves mechanistic approaches that need to be understood properly. They cannot be degraded by biological or chemical means and thus can only be converted to less harmful forms. The conventional detection methods include biosensors, voltammetry, atomic absorption spectrometry, and inductively coupled plasma with atomic emission spectrometry. All such strategies for metal detection and mitigation strategies are covered in this title under one section. This book incorporates classical views along with modern scientific approaches to develop an understanding of the subject matter suitable for academicians, researchers, planners, policymakers, NGOs, and environmental consultancies and raise awareness on this concern. Topics representing diverse sections namely environmental impacts, biological effects, and methods used for detection and remediation have been included to address all possible contemporary issues on the topic in one concise volume.

Download or read book Heavy Metal Soil Concentrations in the Urban Toledo Ohio Area written by Karen R. Burris and published by . This book was released on 2021 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban environments have a history of anthropogenic input of heavy metals to soils. Toledo, Ohio is an urban setting that has been altered through heavy industry and transportation dating back to the 1800s. Heavy metal contamination in soil has been shown to cause serious health effects in humans, such as brain damage, birth defects, cancer, and even death.A total of 137 Toledo soil samples were collected in collaboration with local Toledo schools, the Manos Community Garden, and a previous study completed by Stewart et al (2014). Stewart's study samples and the local Toledo schools' soil samples were collected by K-12 students through a hands-on citizen science project. The samples were analyzed to determine the concentrations of a series of heavy metals, including arsenic, cadmium, chromium, lead, nickel, and zinc. The results revealed multiple samples with elevated levels of all six focus metals greater than the Ohio EPA's soil background levels of the region. Two of these elements, arsenic and lead, had concentrations higher than the USEPA screening level for soils of this region in 73% and 7% of samples, respectively. Locations with elevated heavy metals concentrations in soils were mostly residential yards with older houses and within areas of high transportation. Therefore, the elevated levels of heavy metals were likely deposited from a legacy of human activities. Heavy metal predictive concentration maps of the Toledo, Ohio area were created to show possible areas of concern. The predictive maps showed a higher concentration of most elements in the Old West End area of Toledo. The findings were presented to the collaborating schools and in public forums to educate citizens about elevated heavy metal soil contamination in their area. They were given possible reasons for the contamination, explaining the harmful side effects of human activities on the soils. The health risks associated with the contamination were presented along with how to prevent health issues and how to take precautions around heavy metals.
Download or read book Environmental Impacts of Road Vehicles written by R M Harrison and published by Royal Society of Chemistry. This book was released on 2017-06-16 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first concerns that come to mind in relation to pollution from road vehicles are direct emissions of carbon dioxide and toxic air pollutants. These are, of course, important but the impacts of road traffic are altogether more substantial. This volume of the Issues in Environmental Science and Technology Series takes a broader view of the effects on the environment and human health, excluding only injury due to road traffic accidents. By looking across the environmental media, air, water and soil, and taking account also of noise pollution, the volume addresses far more than the conventional atmospheric issues. More importantly, however, it examines present and future vehicle technologies, the implications of more extensive use of batteries in electric vehicles and the consequences of recycling vehicles at the end of use. Finally, examples of life-cycle analysis as applied to road vehicles are reviewed. This book is a comprehensive source of authoritative information for students studying pollution, and for policy-makers concerned with vehicle emissions and road traffic impacts more generally.
Download or read book Urban Soils written by Andrew W. Rate and published by Springer Nature. This book was released on 2022-01-07 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook addresses the increasing trend in urbanization of the world’s population and its relation with urban soils. Written by active practitioners of university level teaching and research, this book is designed primarily as an educational text, while it also provides readers with an authoritative gateway to the primary literature. It includes explicit coverage of spatial and statistical (multivariate) techniques and case studies to illustrate key concept, and to support practical guidance in issues such as data collection and analysis. The authors reflect current developments in research and urban trends. In China, for example, the proportion of the population living in cities increased from 13% in 1950 to 45% in 2010 (World Bank data). Australia is one of the world's top ten urbanised countries with population greater than ten million, with approximately 90% of its population living in cities, mainly along Australia's coast. The most rapidly urbanising populations are currently in nations of the African continent. Soils in urban areas have multiple functions which are becoming more valued by urban communities: soils supply water, nutrients and physical support for urban plant and animal communities (parks, reserves, gardens), and are becoming increasingly valued for growing food. Soils may be used for building foundations, or as building materials themselves. Urban hydrology relies on the existence of unsealed soils for aquifer protection and flood control. This volume presents the importance of urban ecosystems and the impacts of global change. It examines pedogenesis of urban soils: natural materials affected by urban phenomena, and natural processes acting on urban materials, including an examination of different climatic zones. There is a focus on soils formed on landfill, reclaimed land, dredge spoils as well as soil-related changes in urban geomorphology. There is plenty of discussion on urban soil as a source and sink as well as soil geochemistry and health. The book is intended primarily as a text for upper-level undergraduate, and postgraduate (Masters) students. It will also be invaluable as a resource for professionals such as researchers, environmental regulators, and environmental consultants.
Download or read book Heavy Metals written by Hosam El-Din M. Saleh and published by BoD – Books on Demand. This book was released on 2018-06-27 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental societal changes resulted from the necessity of people to get organized in mining, transporting, processing, and circulating the heavy metals and their follow-up products, which in consequence resulted in a differentiation of society into diversified professions and even societal strata. Heavy metals are highly demanded technological materials, which drive welfare and progress of the human society, and often play essential metabolic roles. However, their eminent toxicity challenges the field of chemistry, physics, engineering, cleaner production, electronics, metabolomics, botany, biotechnology, and microbiology in an interdisciplinary and cross-sectorial manner. Today, all these scientific disciplines are called to dedicate their efforts in a synergistic way to avoid exposure of heavy metals into the eco- and biosphere, to reliably monitor and quantify heavy metal contamination, and to foster the development of novel strategies to remediate damage caused by heavy metals.
