Download or read book Mobility of Heavy Metals in Soils and Tailings at the Hanover and Bullfrog Tailings Sites Silver City New Mexico written by Tanya G. Baker and published by . This book was released on 1993 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hanover Mining District, located east of Silver City in south west New Mexico, has been mined since at least the 1600's. The majority of production was for iron and base metals such as Cu, Zn, and Pb. The two sites of interest in this study are the Hanover and Bullfrog tailings piles. Tailings were produced from Zn-Pb sulfide-vein deposits. The main ore mineral at Hanover is sphalerite. Ankerite, specular hematite, pyrite, and pyrrhotite are common gangue minerals. The main ore minerals at Bullfrog (derived from three mines) are sphalerite and galena. Gangue minerals include quartz, pyrite, manganiferous calcite, chlorite, and rarely barite. Movement of heavy metals from the tailings piles may occur by wind transport of metal-containing particles, fluvial transport, aqueous transport, and/or plant uptake. To determine the mobility of heavy metals present at the sites, surrounding soils, vegetation, and surface water were sampled and analyzed. Soils were sampled at the surface and at depth to determine possible downward movement. Foliar samples were taken to determine metal concentrations in plants on and near the tailings. Surface water samples were taken from Hanover Creek above, adjacent to, and below the Hanover tailings to determine possible contamination from the tailings. Surface soil samples taken in an area affected by wind-transported tailings material show slightly elevated Pb, Zn, and Cu concentrations above background. Concentrations of these metals drop to background levels below 2-4 cm in depth. Plant samples show little uptake of heavy metals even in samples taken on the edge of the tailings piles where wind transported material had engulfed the plant. Water samples taken adjacent to and below the Hanover tailings contain fewer total dissolved solids and lesser concentrations of the main ions SO4, and Ca than those taken upstream of the tailings. This is probably due to the presence of calcium carbonate in the tailings material. These results, together with the alkaline nature of the soils and arid climate of the southwest United States, indicate the probability of dissolved aqueous transport of heavy metals away from the tailings is low. It is recommended that the tailings be covered with topsoil and revegetated to decrease any effects the tailings may have on the surrounding environment.

Download or read book Soil Heavy Metals written by Irena Sherameti and published by Springer Science & Business Media. This book was released on 2010-01-12 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activities have dramatically changed the composition and organisation of soils. Industrial and urban wastes, agricultural application and also mining activities resulted in an increased concentration of heavy metals in soils. How plants and soil microorganisms cope with this situation and the sophisticated techniques developed for survival in contaminated soils is discussed in this volume. The topics presented include: the general role of heavy metals in biological soil systems; the relation of inorganic and organic pollutions; heavy metal, salt tolerance and combined effects with salinity; effects on abuscular mycorrhizal and on saprophytic soil fungi; heavy metal resistance by streptomycetes; trace element determination of environmental samples; the use of microbiological communities as indicators; phytostabilization of lead polluted sites by native plants; effects of soil earthworms on removal of heavy metals and the remediation of heavy metal contaminated tropical land.

This book was released on 2014 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy metals cadmium, lead, and zinc present in soil and sediment in high concentration may pose a threat to human (and wildlife) health. Several soil surveys have focused in the area encompassing Turkey Creek and Joplin, Missouri, due to its proximity to the historic Tri-State Lead and Zinc Mining District. The Tri-State Mining District is an area of extensive mining for over a century (1850-1960s) that resulted in soil contamination. Contaminant levels were considered toxic enough to declare part of this area an EPA Superfund site. Mixed media samples (soil, sediment, and chat) were collected throughout the summer of 2013 and were analyzed using aqua regia-Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). Significant positive and negative correlations were found between metals, as well as metal content and distance from mine waste piles and the smelter zone. Enrichment Factor (EF) and Geoaccumulation Index (IG) were both calculated and identified sites of highest contamination/enrichment. Inverse Distance Weighted (IDW) interpolation was used to generate metal concentrations around Turkey Creek Watershed and visualize the potential regions of highest concern. This study has identified areas of the watershed where metal contents are high and should be examined more closely to further remediation efforts.

Available in PDF, EPUB and Kindle. Book excerpt: Heavy metals in soils continue to receive increasing attention due to the growing scientific and public awareness of environmental issues and the development of analytical techniques to measure their concentrations accurately. Building on the success and acclaim of the first edition, this book continues to provide an up-to-date, balanced and comprehensive review of the subject in two sections: the first providing an introduction to the metals chemistry, sources and methods used for their analysis; and the second containing chapters dealing with individual elements in detail.

Book excerpt: Metals are naturally present in our environment and trace amounts of metals are essential micronutrients for the growth of many marine organisms. However, excessive amounts of heavy metal can be toxic to marine life. In this book, the authors gather topical research from around the globe in the study of heavy metal sediments. Topics discussed in this compilation include the distribution of heavy metals and total petroleum hydrocarbons in soils near a petrochemical complex in China; heavy metals in coastal sea sediments of the eastern Adriatic Sea; environmental assessments of metal concentrations in select rivers, estuaries and coastal sediments; iron contamination in the Bizerte Lagoon of Tunisia and the correlation between millennial mining activities and heavy metal pollution in Spanish estuaries.

Download or read book Heavy Metals Accumulation Within Black Hills Region Reservoirs of South Dakota and Wyoming and Downriver of New Idria Mine in San Benito County California written by Rohit K. Sharma and published by . This book was released on 2016 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation focused on the two diverse watersheds that are affected by historical mining in the Black Hills in South Dakota and New Idria District of San Benito County, California. None of the previous work related to these two anthropogenic altered watersheds has used catchment weathering or pollution indices to derive pollution trends. It is important to understand how weathering contributes to the pollution down gradient of these watersheds and then test them using pollution indices. In the Black Hills and New Idria region, solid phase sediments are chiefly composed of silicate and secondary clay minerals, such as aluminosilicate clay minerals. Pollution from the abandoned mines is a great environmental concern in these regions, as the heavy metals may be transported from the mining areas to the water resources downgradient, leading to environmental degradation.
