Description : Due to its inherent characteristics, mercury contamination from gold mining is a major environmental problem compared to past mercury contamination from industrial point sources. The worsening of social-economical conditions and increasing gold prices in the late 1970s resulted in a new rush for gold by individual entrepreneurs for whom Hg amalgamation is a cheap and easily carried out operation. Even after the present-day mining areas are exhausted, the mercury left behind will remain part of the biochemical cycle of the tropical forest. This book reviews the current information on mercury from gold mining, its cycling in the environment and its long-term ecotoxicological impact. The book is illustrated with numerous diagrams and photographs.
Description : The smallest planet in our solar system is also the closest to the sun. That means on Mercury, one year is just 88 days long! Discover more facts about the small but mighty Mercury.
Description : This book contains 57 chapters describing the results of original research and reviewing the state-of-the-science with respect to environmental mercury. Topics include analytical methodology, atmospheric cycling, freshwater and marine ecosystems, terrestrial processes, bioaccumulation, modeling, pollution and remediation, and human health and public policy.
Description : This fascinating book reviews the progress made in Mercury studies since the flybys by Mariner 10 in 1974-75. Thus far, it is the only book on Mercury which balances a wide range of Earth-based observations, made under difficult conditions, with the only available space-based data. The text is based on continued research using the Mariner 10 archive, on observations from Earth, and on increasingly realistic models of this mysterious planet’s interior evolution.
Description : Venus and Mercury have long been regarded as difficult targets for amateur observers, but advances in commercially-made telescopes have brought them within the skills of observers of only moderate experience. Peter Grego’s fascinating book presents an up-to-date, detailed description of the history and geology of the so-called inferior planets, and provides the latest, most useful advice on observing and recording them with commercially-available telescopes and cameras. The book also offers a wealth of detailed practical information on every aspect of observing, from safely targeting the two planets, through visual observing, to sketching and electronic imaging.
Description : Although this is a handbook for policy and regulation, the major part of it is filled with data on the three heavy metals that served as examples: mercury, cadmium and lead. Their stocks, productions, prices, trade flows, uses and applications, recovery and recycling, as well as their (eco)toxicological characteristics have been collected and presented to their fullest extent. In addition, they are thoroughly analysed for consistency, future developments and trends and, of course, their consequences for sustainable development and future policy and regulation. The second part, on policy and regulation, begins with an extensive and fundamental consideration on the characteristics of a sustainable heavy metals policy, whereby innovative policy tools are developed. In many aspects, these considerations are also valid for other metals and even non-metallic persistent substances. Addressing the European Union in particular, its policy-making structure and practice are critically analysed, in order to develop feasible and viable guidelines for long-, medium- and short-term EU policy measures. The results of this exercise are then applied to the three heavy metals. In each of these three chapters, all existing EU measures are presented in detail and confronted with better practices elsewhere, resulting in many suggestions and recommendations for the future. In the last chapter, the main conclusions and recommendations are carefully summarised. Together with a very extended table of contents, this makes the book easily accessible, in spite of its volume. This Handbook is a must for policy-makers and administrators at all levels, as well as for their counterparts in a wide variety of industries. In addition, it is well-suited for environmental science courses at academic or higher professional level.
