This outstanding volume enables researchers to develop robust sensors and instruments for automatic 'on site' measurement of water quality. The need for an efficient multi-parameter monitoring system is ever-increasing, given that human activity is impacting so greatly on ecosystems and the increased need to develop our understanding of the underlying environmental processes. Edited by two renowned experts, this book evaluates developments over the last 10-20 years which will form the basis of future sophisticated in situ monitoring systems. The emphasis is on micro-analytical monitoring techniques and microtechnology. * Critically discusses the state of the art of existing techniques and devices * Overviews what can be expected in terms of performance * Outlines possible improvements in the future This book will be invaluable to both researchers interested in the development of environmental monitoring systems and laboratories in charge of water quality assessment by providing them with a critical evaluation of existing and possible future options.

With regional, national, and global processes affecting both the structure and function of lakes and rivers, assessment methodology must encompass many attributes to evaluate the impact of these processes on water quality. Many of the changes in biological communities correlate to resource exploitation, nonpoint pollutant interactions, and habitat alteration - factors that can be missed by routine chemical sampling. This creates the need for ecologically-based approaches to this problem. Biological monitoring is a fundamental part of an ecologically-based approach. Biological Monitoring of Aquatic Systems brings together contributions by authors recognized as leaders in the development and utilization of biological monitoring techniques for freshwater ecosystems. It provides a conceptual framework for the use of biological monitoring to assess the environmental health of freshwater resources. Biological monitoring is an important part of any water quality assessment program. Biological Monitoring of Aquatic Systems provides you with an understanding of water resources. It includes discussions concerning historical development, ecological basis, experimental design characteristics, case studies, and future concerns. As efforts to maintain and restore the world's water resources intensify, the need to develop accurate methods to assess the health of these resources becomes critical.

Overall, microsensors capable of measuring pH, oxidation-potential reduction (ORP), dissolved oxygen (DO), ammonia (NH3), hydrogen peroxide (H2O2), and zinc (Zn2+) were developed and applied to the systems described above to significantly contribute to a better understanding of interfacial transport mechanisms in various natural and engineered systems.

This reference book collates traditional and modern applications of remote sensing in aquatic ecosystem monitoring. It covers conventional assessment methods like sampling, surveying, and chlorophyll estimation. Advanced remote sensing technology provides timely spectral information for quantitative and qualitative assessment of water changes, volume, and vegetation. The book discusses space-borne, airborne, and drone geospatial data. The five sections broadly cover aquatic ecosystem monitoring, vegetation management, advanced modelling practices, and challenges. Key features Covers different types of aquatic ecosystems like wetlands, rivers, lakes, saline, and brackish Reviews the latest applications of remote sensing in the monitoring and assessment of aquatic ecosystems Includes traditional methods like cartography, sampling, surveying, phytoplankton assessment and chlorophyll estimation Discusses the application of artificial intelligence, machine learning, data fusion in monitoring aquatic systems Explores the prospects of future Earth observation space missions for aquatic ecosystem monitoring The book is meant for scientists, professionals, and policymakers working in environmental sciences, remote sensing, and geology.

This detailed volume examines the complex study of the assessment of in situ bioavailability and toxicity of organic chemicals in aquatic systems with a toolbox of reliable techniques. Beginning with a section on approaches for chemical analytical and bioanalytical techniques in bioavailability research, the book continues with methods to monitor effects in situ and conduct bioassays to assess the effects of complex environmental samples. It concludes with descriptions of various computational models. Written for the Methods in Pharmacology and Toxicology series, chapters feature the kind of expert implementation advice that leads to greater success in the field. Authoritative and versatile, In Situ Bioavailability and Toxicity of Organic Chemicals in Aquatic Systems serves as an ideal guide to aid in tackling the challenge of analyzing and understanding chemical pollution in aquatic systems.
