Ecotoxicology


Book Description

Ecotoxicology offers a comprehensive overview of the science underpinning the recognition and management of environmental contamination. It describes the toxicology of environmental contaminants, the methods used for assessing their toxicity and ecological impacts, and approaches employed to mitigate pollution and ecological health risks globally. Chapters cover the latest advances in research, including genomics, natural toxins, endocrine disruption and the toxicology of radioactive substances. The second half of the book focuses on applications, such as cradle-to-grave effects of selected industries, legal and economic approaches to environmental regulation, ecological risk assessment, and contaminated site remediation. With short capsules written by invited experts, numerous case studies from around the world and further reading lists, this textbook is designed for advanced undergraduate and graduate one-semester courses. It is also a valuable reference for graduate students and professionals. Online resources for instructors and students are also available.




OECD Series on Testing and Assessment Guidance on the Incorporation of Bioavailability Concepts for Assessing the Chemical Ecological Risk and/or Environmental Threshold Values of Metals and Inorganic Metal Compounds


Book Description

Several models, tools and methods have been published in the past 20 years to include bioavailability in risk assessment and several OECD member countries already have developed frameworks and published guidance documents for taking metal specificities into account in environmental risk ...




Ecotoxicology of Nanoparticles in Aquatic Systems


Book Description

The use of nanoparticles in medicine, industrial, and other applications has triggered an interest in their potential. This book explores the use of nanoparticles related to their occurrence in the environment, their impact on biota in aquatic systems, application of new methodologies, and changes associated with new global scenarios. The book also covers the bioaccumulation and internalization of nanoparticles as key aspects to assess their uptake and discusses the methodologies for testing ENPs ecotoxicity at different trophic levels.




Fish Physiology: Homeostasis and Toxicology of Essential Metals


Book Description

Homeostasis and Toxicology of Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses. The companion volume, Homeostasis and Toxicology of Non-Essential Metals, Volume 31B, covers metals that have no known nutritive function in fish at present, but which are toxic at fairly low levels, such as Ag, Al, Cd, Pb, Hg, As, Sr, and U. In addition, three chapters in Volumes 31A and 31B on Basic Principles (Chapter 1, 31A), Field Studies and Ecological Integration (Chapter 9, 31A) and Modeling the Physiology and Toxicology of Metals (Chapter 9, 31B) act as integrative summaries and make these two volumes a vital set for readers. - All major essential metals of interest are covered in metal-specific chapters - Each metal-specific chapter is written by fish physiologists/toxicologists who are recognized authorities for that metal - A common format is featured throughout this two volume edition

Assessing the Hazard of Metals and Inorganic Metal Substances in Aquatic and Terrestrial Systems


Book Description

Current procedures used for hazard identification and classification are based on persistence, bioaccumulation, and toxicity measurements. Assessing the Hazard of Metals and Inorganic Metal Substances in Aquatic and Terrestrial Systems provides the basis for improvements to the current model for hazard assessment. The book reviews the scientific un




Improving Farmed Fish Quality and Safety


Book Description

Global aquaculture production has grown rapidly over the last 50 years. It is generally accepted that there is limited potential to increase traditional fisheries since most fish stocks are well or fully exploited. Consequently increased aquaculture production is required in order to maintain global per capita fish consumption at the present level. Fish farming enables greater control of product quality and safety, and presents the possibility of tailoring products according to consumer demands. This important collection reviews safety and quality issues in farmed fish and presents methods to improve product characteristics.The first part of the book focuses on chemical contaminants, chemical use in aquaculture and farmed fish safety. After an opening chapter discussing the risks and benefits of consumption of farmed fish, subsequent contributions consider environmental contaminants, pesticides, drug use and antibiotic resistance in aquaculture. Part two addresses important quality issues, such as selective breeding to improve flesh quality, the effects of dietary factors including alternative lipids and proteins sources on eating quality, microbial safety of farmed products, parasites, flesh colouration and off-flavours. Welfare issues and the ethical quality of farmed products are also covered. The final part discusses ways of managing of product quality, with chapters on HACCP, monitoring and surveillance, authenticity and product labelling.With its distinguished editor and international team of contributors, Improving farmed fish quality and safety is a standard reference for aquaculture industry professionals and academics in the field. - Reviews safety and quality issues in farmed fish and presents methods to improve product characteristics - Discusses contaminants, persistent organic pollutants and veterinary drug residues and methods for their reduction and control - Addresses important quality issues, genetic control of flesh characteristics and the effects of feed on product nutritional and sensory quality




Risk Management of Complex Inorganic Materials


Book Description

Risk Management of Complex Inorganic Materials: A Practical Guide facilitates the risk assessment and management of complex inorganic materials around the world by providing accessible and specific guidance on their assessment. Inorganic complex materials, such as ores and concentrates, metal containing- glasses, ceramic and inorganic pigments, alloys, and UVCBs produced during the manufacturing of metals present specificities not addressed by most guidance documents. This book explains the main characteristics of inorganic complex materials affecting their hazard and risk assessment and management, including their source and main uses, also covering hazard and exposure assessment, risk characterization and risk management. It is an essential reference for regulators involved in risk assessment and risk management, industry experts charged of compliance with chemical management program requirements, consultants preparing chemicals management files for companies and regulators, and academics involved in research on complex inorganic materials. - Focuses on key information required to globally manage the risk of inorganic complex material - Includes user-friendly descriptions of methodologies and tools that facilitate chemicals management of such materials - Provides key messages to assist communication on risk assessment and risk management to audiences like regulators, workers and communities living around industrial sites
