Trace Elements


Book Description

Over the last few years, we have witnessed increasing efforts dedicated to the scientific investigation and characteristics of trace elements. Especially in the field of human and animal nutrition, trace elements display a considerably attractive issue for research because they play an essential role in the nutrition of both animals and humans. Aquatic environments contaminated with trace elements are an emerging research area due to the toxicity, abundance, and environmental persistence of trace elements. Accumulation of heavy metals as a class of trace elements in various environments, and the subsequent transition of these elements into the food and feed chain, severely affects human health. The determination of type and concentration of trace elements is regarded as the first and most important step to follow the mechanisms controlling the dispersal and accumulation of trace elements. Element speciation in different media (water, soil, food, plants, coal, biological matter, food, and fodder) is pivotal to assess an element's toxicity, bioavailability, environmental mobility, and biogeochemical performance. Recently, new analytical techniques have been developed, which greatly simplified the quantitation of many trace elements and considerably extended their detection range. In this context, the development of reproducible and accurate techniques for trace element analysis in different media using spectroscopic instrumentation is continuously updated.




Trace Element-mineral Associations in the Regolith, Scuddles Massive Cu-Zn Sulphide Deposit, Western Australia


Book Description

Open file report 197 is a second impression (second printing) of CRC LEME restricted report 195R. It was produced in July 2003 for Newmont Australia. The period of confidentiality has now expired. The association between trace elements and regolith minerals has been studied at the Scuddles Cu-Zn sulphide deposit Golden Grove, Western Australia. The Scuddles deposit is located in the Golden Grove district in the Murchison province of the Archaean Yilgarn Craton. The mineralogy and the trace element abundance were characterised using a combination of bulk and in situ micro-analytical techniques.The determination of low abundance elements in the minerals was carried out with in situ Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS).







Distribution of Selected Trace Elements in Rocks


Book Description

This report discusses factors influencing trace element distribution in rocks, tabulates maximum and minimum concentrations of twenty-nine trace elements in various common rock types, and briefly describes the geochemical behavior of each of these elements. A procedure is outlined for predicting concentrations of these selected elements in various rock types. On the basis of this study it is concluded that: 1. Trace element concentration varies systematically according to the gross mineralogical composition of the host rock. 2. Mineralogical composition of the host rock is the primary determinant of trace element concentrations. 3. Knowledge of rock mineralogy as provided by conventional petrographic analyses serves as a basis for estimating trace element concentrations.




The Handbook of Trace Elements


Book Description

Compiled by two of the world’s experts in the field, The Handbook of Trace Elements brings together into a single source a complete listing of the trace elements found in both naturally occurring and manmade substances in the environment. The book provides a thorough description by element for 41 trace elements, transition metals, and micronutrients found in Earth's crust, soil, water, plants, animals, and humans. Elucidating the ecological impact of industrial waste and health problems in animals and humans, this widely accessible resource continues to provide a reliable reference for researchers, scientists, and other professionals engaged in the study of trace elements.
