Available in PDF, EPUB and Kindle. Book excerpt: 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.

It gives an exhaustive account of the most reliable procedures for sampling, sample preparation, analytical determinations and interpretation of data. Using an ecophysiological approach, metal uptake by plants and metal transfer along terrestrial food chains are examined.
Download or read book Atmospheric Trace Elements and Their Application in Tracing Air Pollution written by Yin-Sang Shum and published by . This book was released on 1973 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atmospheric trace element abundances associated with several major sources of air pollution in Western Oregon, such as the paper industry, the metallurgical processing industry, the plywood industry and agricultural field burning have been measured by instrumental neutron activation analysis (INAA). Air samples were collected directly from industrial stacks and during the field burning season using high volume air samplers, tape samplers and a cascade impactor. Nuclepore filter paper and Handiwrap were used as collection media for air particulates. The results show that some of the trace elements are highly correlated with a particular source of pollution, e. the high concentration of Zr, Hf, Ta, As, Cl, and Br associated with the metallurgical processing company; Na, Cl, Br, Cu, V, Co, Cr and Hg with the paper company; Na, K, Cl, Cr, Cu, Br and Hg with the plywood company and Ti, Na, Al, K, and Fe with agricultural field burning. Of all these characteristic elements, only Zr, Hf, Ta and As could be used as "natural occurring" tracers for tracing the dispersal pattern of stack effluent from a particular source. The concentrations of potentially toxic elements such as Hg, A.s, Se, and V emitted from these sources into the atmosphere were found to be too low to cause any health hazard in the area concerned. The atmospheric trace element abundances in Albany (an industrial area) and in Corvallis (a rural area) were also measured. Abnormally high trace element concentrations were found in the Albany area. Most of the trace element concentrations are highly correlated to the industries in the area. The rural air in Corvallis, on the other hand, shows very low trace element concentrations and may serve as an indication of the "continental background" contribution to atmospheric abundance. An artificial activable tracer technique using some of the rareearth elements (Dy, Sm, La, and Ce) was also developed to monitor stack effluent. These tracers were used in testing the generalized Gaussian plume model (Gifford, 1962) and Hewson's trapping plume model (Hewson, 1958) applied to describe the dispersal pattern of stack effluent in the Albany area. These models were found to work quite well under atmospheric stabilities types D, C, and B (Pasquill's classification, 1962) and not to work well under very turbulent conditions (atmospheric stability type A. or above). These meteorological models along with the techniques of multiple regression analysis were applied to predict the emission rates of the stack effluent involving multiple sources of air pollution in the Albany area. The artificial activable tracers were used as source tracers. It was found that these models, in general, can be applied to predict the emission rates withinafactor of two in multiple sources involving three stacks.
Download or read book Trace Metals in the Environment written by Daisy Joseph and published by BoD – Books on Demand. This book was released on 2023-09-27 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: High levels of toxic elements have harmful effects on all aspects of the environment (water, air, plants, etc.). Trace elements, many of which are heavy metals, can compromise soil quality, cause toxicity to plants, and ultimately contaminate the food chain. This book summarizes the effects of trace elements in the environment. Section 1 discusses the influence of trace elements on soil and the ecosystem and Section 2 examines the influence of trace elements on water. The book also discusses microplastics, which accumulate trace elements and pollute the oceans, harming both aquatic and human life.
