The ongoing progress of science has shown that it is important for analytical scientists to determine not only the presence of particular elements, but also their species. There are many fields where this is applicable, and where there are a number of topics to be addressed. Developing separation and measurement systems for the many element species has tested the resourcefulness of analytical chemists over recent decades. A product of the EU sponsored Speciation 21 Network, this book presents a detailed review of the state-of-the-art of speciation issues in the occupational health, food and environment sectors, along with the main conclusions arising from discussions held during expert meetings. Topics covered include mercury and organotin compounds in the environment; factors affecting the health of workers; the importance of speciation of trace elements for health, and subsequent metabolism in the body; analytical methodologies; risk assessment; and legislation. Trace Element Speciation for Environment, Food and Health provides an insight into applied research in the speciation field and how it has become so important in all the fields represented. With its comprehensive coverage, it will be of particular interest to researchers in industry and academia, as well as government agencies and legislative bodies.
This two-volume handbook, prepared by Editors involved in an EU validation project on speciation, provides comprehensive coverage of the sample preparation methods and analytical techniques utilised for speciation of different elements in environmental, food, and clinical samples. Handbook of Elemental Speciation I - Techniques and Methodology brings together a collection of chapters covering different aspects of procedures for speciation analysis at the different levels starting from sample collection and storage, through sample preparation approaches to render the species chromatographable, principles of separation techniques used in speciation analysis, to the element specific detection. Also covers quality assurance and risk assessment, and speciation-relevant legislation. Handbook of Elemental Speciation II - Species in the Environment, Food, Medicine and Occupational Health provides a comprehensive, cross-disciplinary presentation of the analytical techniques involved in speciation. * Comprehensive coverage of key elements and compounds in situ * Addresses the analysis and impact of these elements and compounds, e.g. arsenic, lead, copper, iron, halogens, etc., in food, the environment, clinical and occupational health * Detailed methodology and data are reported, as well as regulatory limits * Includes general introduction on the impact in these key areas
QUANTITATIVE ENVIRONMENTAL RISK ANALYSIS FOR HUMAN HEALTH An updated edition of the foundational guide to environmental risk analysis Environmental risk analysis is a systematic process essential for the evaluation, management, and communication of the human health risk posed by the release of contaminants to the environment. Performed correctly, risk analysis is an essential tool in the protection of the public from the health hazards posed by chemical and radioactive contaminants. Cultivating the quantitative skills required to perform risk analysis competently is a critical need. Quantitative Environmental Risk Analysis for Human Health meets this need with a thorough, comprehensive coverage of the fundamental knowledge necessary to assess environmental impacts on human health. It introduces readers to a robust methodology for analyzing environmental risk, as well as to the fundamental principles of uncertainty analysis and the pertinent environmental regulations. Now updated to reflect the latest research and new cutting-edge methodologies, this is an essential contribution to the practice of environmental risk analysis. Readers of the second edition of Quantitative Environmental Risk Analysis for Human Health will also find: Detailed treatment of source and release characterization, contaminant migration, exposure assessment, and more New coverage of computer-based analytical methods A new chapter of case studies providing actual, real-world examples of environmental risk assessments Quantitative Environmental Risk Analysis for Human Health is must-have for graduate and advanced undergraduate students in civil engineering, environmental engineering, and environmental science, as well as for risk analysis practitioners in industry, environmental consultants, and regulators.

Risk Assessment for Human Metal Exposures: Mode of Action and Kinetic Approaches examines the current principles of risk assessment in human metal exposures, with a focus on Mode of Action(MOA), Toxicokinetic and Toxicodynamic (TKTD) considerations, and computer models. Derived from the highly respected Handbook on the Toxicology of Metals, Fourth Edition (2014), the book summarizes principles and methods and provides examples of how MOA –TKTD can be used. In addition, it presents tactics on how information generated by such methods can be confirmed by epidemiological data. Furthermore, it demonstrates how epidemiological data can be confirmed and evaluated by the examined models and considerations. This resource uniquely integrates several important topics, such as risk assessment, characterization, management and communication—the classic risk assessment paradigm—with mode of action, TKTD, and epidemiology, all topics related to human exposure. Written by pioneers in the field, this book is an essential reference for researchers, students and technicians in toxicology and risk assessment. Covers fundamental risk assessment concerns for the effects of metals on human health Provides an easy-to-use structure to quickly locate specific methods Uses case studies to illustrate the methods and theories described Written to be understood by students, researchers and industry workers who need to conduct risk assessment in metals and human health

Numerous applications of heavy metal have caused to their wide contamination in the environmental system and raised serious concerns over potential harmful effects on public health and the environment. Water, sediment, and dietary food are the main exposure media of heavy metal pollution and key determinants of adverse human and environmental health effects. Heavy metal(s) toxicity and speciation involve various mechanistic features with specific media and some of them are not clearly investigated. In particular, biological effects such as toxicity are not related to the total concentration of heavy metals in media, and many laboratory and field studies have supported this supposition. Organisms respond to the bioaccessible and bioavailable fraction of metals only, not the total concentration. The bioaccessibility and bioavailability of toxicants are dependent on chemical properties of the contaminant, the many exposure pathways, and temporal variability of these variables with respect to uptake by the target organism. Usually, bioavailable fractions are estimated using chemical or biological approaches. For this study, biological approaches were performed to better ascertain the toxic effects of heavy metals on organisms. A better understanding of bioaccessibility and bioavailability can be a useful tool in exposure and risk assessment. Therefore, this study presents experimental designs focusing on assessing of the bioaccessibility and bioavailability of metals in aquatic, benthic organisms and dietary food. This study also examines the role of metal mixtures on the adverse effects of metals.
