DOWNLOAD EBOOKAnalysis of Seawater deals with the investigation of the micro-constituents in seawater in terms of nutrient content and environmental concerns. The book describes sampling, determination of anions, analysis of dissolved gases, and metal preconcentration techniques. The book also deals with monitoring radioactive elements, the determination of seawater organics, organometallic compounds, and the oxygen-demand parameters in seawater. It describes in detail surface and deep water sampling, the types of devices used, storage, preservation, and prevention of contamination during sample analysis. In examining dissolved gases, the investigator can use the amperometric titrimetric method (with some reservations) on chlorine, the ultraviolet method on ozone, electron capture gas chromatography on nitric oxide, and also the flow injection analysis on hydrogen sulphide. The methods for determining metals in seawater concern either for single element or for groups of elements. The investigator should always initiate various pre-concentration techniques when determining metals due to their low concentration and occurrence in seawater. The investigator uses various methods to determine different radioactive compounds such as uranium, polonium, thorium, radium, barium, radon, plutonium, strontium-90, and cesium-137. The book can be beneficial for meteorologists, environmentalists, marine ecologists, biologists, oceanographers, fisheries experts, for students studying hydrology, meteorology, as well as for river and lake authorities.

DOWNLOAD EBOOKThis book both describes the chemical parameters that must be measured in the ocean in order to improve our understanding of the ocean's role in the global carbon cycle and recommends technologies of analytical chemistry that could be applied to these parameters. Additionally, the volume recommends how the federal government, ocean scientists, and analytical chemists could work together more closely to speed development of new instruments and implementation of new techniques.

DOWNLOAD EBOOKHigh 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.

Most of the data gathered before the mid-1970s have had to be discarded. Possible associations of organic and inorganic ligands with the metals were throwing views of metal speciation into great uncertainty. Biological effects of metals need to be re-examined after recent revelations of unsuspected metal contaminations in methodology. The investigations appear chaotic, yet exciting.

DOWNLOAD EBOOKAquatic chemistry is becoming both a rewarding and substantial area of inquiry and is drawing many prominent scientists to its fold. Its literature has changed from a compilation of compositional tables to studies of the chemical reactions occurring within the aquatic environments. But more than this is the recognition that human society in part is determining the nature of aquatic systems. Since rivers deliver to the world ocean most of its dissolved and particulate components, the interactions of these two sets of waters determine the vitality of our coastal waters. This significant vol ume provides not only an introduction to the dynamics of aquatic chem istries but also identifies those materials that jeopardize the resources of both the marine and fluvial domains. Its very title provides its emphasis but clearly not its breadth in considering natural processes. The book will be of great value to those environmental scientists who are dedicated to keeping the resources of the hydrosphere renewable. As the size of the world population becomes larger in the near future and as the uses of materials and energy show parallel increases, the rivers and oceans must be considered as a resource to accept some of the wastes of society. The ability of these waters and the sediments below them to accommodate wastes must be assessed continually. The key questions relate to the capacities of aqueous systems to carry one or more pollutants.

DOWNLOAD EBOOKLead in the Marine Environment covers the proceedings of the International Experts Discussion on Lead Occurrence, Fate, and Pollution in the Marine Environment, held in Rovinj, Yugoslavia on October 18-22, 1977. The book focuses on the release of lead to the environment, including the techniques, processes, and technologies involved in the analysis of lead in marine ecosystems. The selection first highlights the impact of human on coastal marine ecosystems; analysis of natural and industrial lead in marine ecosystems; and the occurrence of lead in Northeast Pacific and the effects of anthropogenic inputs. The book also looks at the voltammetric determination of the stability constants of the predominant labile lead complexes in sea water, as well as investigations on the nature of the effective carbonato ligand and experimental verification of a chemical model for trace metal speciation in sea water. The publication reviews studies of lead in water and biological materials using X-ray emission spectroscopy; theoretical studies of the chemical speciation of lead in sea water; and input of lead into the Mediterranean through rivers. The text also explains the chelation of lead by organic ligands in sea water and potentialities and limitations of atomic absorption spectroscopy in environmental and biological materials with reference to lead determinations. Concerns include aspects of chelation of heavy metal traces in sea water and typical lead values and analytical data for biological and environmental materials. The selection is a vital source of data for readers interested in studying the effects of lead on the environment.

DOWNLOAD EBOOKThis book discusses in detail the application of physical separation procedures together with modern instrumental analysis techniques such as HPLC, gas chromatography, and anodic strip-ping voltammetry. Particular emphasis is given to environmental samples where the greatest concern for the effects of speciation on trace element transport, toxicity, and bioavailability have been ex-pressed. Special chapters are also devoted to methods of sam-pling and storage, and to the mathematical modeling of chemical speciation. Although designed for the practical analytical chemist, this publication is essential reading for researchers in or entering the field of chemical speciation.
