This book was released on 2019-03-01 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Effect of Heavy Metal Pollution on Plants written by N. W. Lepp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

Download or read book High Resolution Continuum Source AAS written by Bernhard Welz and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-resolution continuum source atomic absorption spectrometry (HR-CS AAS) is the most revolutionary innovation since the introduction of AAS in 1955. Here, the authors provide the first complete and comprehensive discussion of HR-CS AAS and its application to the analysis of a variety of difficult matrices. Published just in time with the first commercial instrument available for this new technique, the book is a must for all those who want to know more about HR-CS AAS, and in particular for all future users. The advantages of the new technique over conventional line-source AAS are clearly demonstrated using practical examples and numerous figures, many in full color. HR-CS AAS is overcoming essentially all the remaining limitations of established AAS, particularly the notorious problem of accurate background measurement and correction. Using a continuum radiation source and a CCD array detector makes the spectral environment visible to several tenths of a nanometer on both sides of the analytical line, tremendously facilitating method development and elimination of interferences. Conceived as a supplement to the standard reference work on AAS by B. Welz and M. Sperling, this book does not repeat such fundamentals as the principles of atomizers or atomization mechanisms. Instead, it is strictly focused on new and additional information required to profit from HR-CS AAS. It presents characteristic concentration for flame atomization and characteristic mass data for electrothermal atomization for all elements, as well as listing numerous secondary lines of lower sensitivity for the determination of higher analyte concentrations. The highly resolved molecular absorption spectra of nitric, sulfuric and phosphoric acids, observed in an air-acetylene flame, which are depicted together with the atomic lines of all elements, make it possible to predict potential spectral interferences.

Download or read book Hazards associated with animal feed written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-11-04 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for feed for terrestrial and aquatic animals continues to rise with the increasing demand for foods of animal origin; however, the challenge is not only to meet the growing need for feed but also to ensure its safety and thus contributing to the safety of the entire food chain. Feed safety incorporates the impact on human as well as animal health and welfare, which, in turn, can affect productivity. Hazards in feed may be inherent to feed ingredients as well as introduced during feed production, processing, handling, storage, transportation, and use. Hazards in feed may also result from accidental or deliberate human intervention. The expert meeting reviewed and discussed potential hazards in feed of chemical, biological and physical origin. It addressed hazards, as well as their occurrence in feed are described, and transfer from feed to food, relevance for food safety, impact on animal health, and emerging issues and trends. In addition, specific consideration was given to feed and products of feed production technologies of increasing relevance, for instance insects, former food and food processing by-products, biofuels (bioethanol and biodiesel) by-products, aquatic plants and marine resources.
