This book discusses the physicochemical changes (transformations) that metals deposited on urban road surfaces undergo during dry weather periods, in order to provide insights into their potential impacts on stormwater quality. Based on extensive field experiments, and laboratory and data analyses, it examines transformation characteristics of metals with respect to the particle size of road dust, antecedent dry days and land uses. Further, it proposes a new risk-assessment methodology, improving the original human health-risk indices based on the transformation characteristics and potential bioavailability of metals in order to evaluate the risks posed by metals in stormwater. This book is of interest to researchers and decision-makers developing appropriate pollution mitigation measures to enhance the quality of stormwater, targeting the effective reuse of stormwater in urban areas.

This book presents a detailed analysis in relation to human health risk assessment of the main toxic chemical pollutants in urban stormwater generated from urban traffic and land use activities. The knowledge presented in this book was derived based on comprehensive experimental investigations including field sampling, laboratory testing, mathematical modelling, spatial analysis and multivariate and univariate statistical data analyses. The key highlights of the book include the quantitative assessment of the human health risk posed by key toxic chemical pollutants in urban stormwater and the development of linkages between risk and traffic and land use. Additionally, a suite of mathematical equations are presented to predict human health risk based on traffic and land use characteristics through mathematical modelling. These outcomes can significantly assist in effective stormwater risk management under changing traffic and land use in the urban environment. The knowledge presented is of particular interest to readers such as stormwater treatment design specialists, decision-makers and urban planners since these outcomes provide practical suggestions and recommendations for effective urban stormwater treatment design.

This 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.

Hydrology and water resources analysis can be looked at together, but this is the only book which presents the relevant material and which bridges the gap between scientific processes and applications in one text. New methods and programs for solving hydrological problems are outlined in a concise and readily accessible form. Hydrology and Water Resource Systems Analysis includes a number of illustrations and tables, with fully solved example problems integrated within the text. It describes a systematic treatment of various surface water estimation techniques; and provides detailed treatment of theory and applications of groundwater flow for both steady-state and unsteady-state conditions; time series analysis and hydrological simulation; floodplain management; reservoir and stream flow routing; sedimentation and erosion hydraulics; urban hydrology; the hydrological design of basic hydraulic structures; storage spillways and energy dissipation for flood control, optimization techniques for water management projects; and methods for uncertainty analysis. It is written for advanced undergraduate and graduate students and for practitioners. Hydrologists and water-related professionals will be helped with an unfamiliar term or a new subject area, or be given a formula, the procedure for solving a problem, or guidance on the computer packages which are available, or shown how to obtain values from a table of data. For them it is a compendium of hydrological practice rather than science, but sufficient scientific background is provided to enable them to understand the hydrological processes in a given problem, and to appreciate the limitations of the methods presented for solving it.

This edited volume presents new data and insights from the most internationally respected PGE experts, representing a variety of disciplines ranging from chemistry, geochemistry, biology, environmental science to toxicology and environmental health. It builds upon three previous co-edited books published by Springer, Zereini and Alt (Eds.) (1999, 2000 and 2006), incorporating the most recent advances on the topic. The book covers the following topical areas related to PGE: sources and applications, analytical methods, environmental fate, bioavailability and chemical behaviour, use of bioindicators and human exposures and health risk potential. Highly interdisciplinary in orientation, this book is a comprehensive guide to academics, students and professionals working in a number of different scientific fields, who are interested in topics related to platinum metal emissions in the environment.
