Publisher:
ISBN:
Category : Metals
Languages : en
Pages : 48

Book Description
Short articles summarize environmental geochemical studies of metallic mineral deposits in Alaska, including massive sulfide, gold, mercury, chromium, and uranium mines and deposits. The studies report metal and acid concentrations in samples collected around such mines and deposits, and evaluate environmental effects of the deposits. The articles are written in a style intended to reach a general audience.

Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments

Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments PDF Author: Elżbieta Kalisińska
Publisher: Springer
ISBN: 3030001210
Category : Science
Languages : en
Pages : 707

Book Description
The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Perspectives on Deep-Sea Mining

Perspectives on Deep-Sea Mining PDF Author: Rahul Sharma
Publisher: Springer Nature
ISBN: 3030879828
Category : Science
Languages : en
Pages : 680

Book Description
This book is a sequel to ’Deep-Sea Mining: Resource Potential, Technical and Environmental Considerations’ (2017) and ‘Environmental Issues of Deep-Sea Mining: Impacts, Consequences and Policy Perspectives’ (2019), and aims to provide a comprehensive volume on different perspectives of deep-sea mining from specialists around the world. The work is timely, as deep-sea minerals continue to enthuse researchers involved in activities such as ascertaining their potential as alternative sources for critical metals for green energy and other industrial applications, as well as technology development for their sustainable exploration and exploitation, while addressing environmental concerns. With a steady increase in the number of contractors having exclusive rights over large tracts of seafloor in the ‘Area’, i.e. area beyond national jurisdictions, the International Seabed Authority, mandated with the responsibility of regulating such activities, is in the process of developing a code for exploitation of deep-sea minerals. These, coupled with growing interest among private entrepreneurs, investment companies and policy makers, underscore the need for updated information to be made available in one place on the subject of deep-sea mining. The book evaluates the potential and sustainability of mining for deep-sea minerals compared to other land-based deposits, the technologies needed for mining and processing of ores, the approach towards environmental monitoring and management, as well as the regulatory frameworks and legal challenges to manage deep-sea mining activities. The book is expected to serve as an important reference for all stakeholders including researchers, contractors, mining companies, regulators and NGOs involved in deep-sea mining.

Metal Deposits in Relation to Plate Tectonics

Metal Deposits in Relation to Plate Tectonics PDF Author: Frederick J. Sawkins
Publisher: Springer Science & Business Media
ISBN: 3662086816
Category : Science
Languages : en
Pages : 677

Book Description
In this book metal deposits, in particular those of non-ferrous and precious metals, are classified and analyzed in terms of their plate tectonic settings. This approach allows a meaningful treatment of metal deposits of different types and provides significant insights into both their genesis and formative environments. The updated 2nd edition incorporates the most significant advances in economic geology of the last 5 years. Particular attention is paid to the geological settings and generative models of gold deposits of all kinds.
