In Situ Monitoring of Aquatic Systems

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.In-situ-Analysenverfahren werden nicht im Labor, sondern (mit Hilfe transportabler Geräte) direkt beim zu analysierenden Medium verwendet. Daher ist es nicht verwunderlich, daß solche Methoden in der Umweltanalytik zunehmend von Bedeutung sind. Dieser vierte Band der IUPAC-Reihe zur Umweltchemie faßt die gängigen In-situ-Prozeduren zur Wasseranalyse zusammen, wobei ein besonderer Schwerpunkt auf Mikrotechniken liegt.

Index.

"Summarising it must be stated that the book reviewed is of top interest for at least analytical chemists, electrochemists, sensor interested researchers and environmentalists. All of them should have this book on his desk for deepening the knowledge and use the book as an excellent source of information." (Chemistry Analysis - Poland, No.46, 2001)

Jacques Buffle and George Horvai are the authors of In Situ Monitoring of Aquatic Systems: Chemical Analysis and Speciation, published by Wiley. The IUPAC Series on Analytical and Physical Chemistry of Environmental Systems provides the scientific community with a critical evaluation of the state of the art on physicochemical structures and reactions in environmental systems. The series is aimed at promoting rigorous analysis and understanding of physiocochemical functioning of environmental systems.

In order to control the impact of human activity on our environment it is necessary to develop efficient multi-parameter monitoring systems in addition to understanding the underlying environmental processes. To carry out the huge numbers of analyses necessary it is not feasible to employ classical sample collection and analysis techniques. Robust sensors and instruments for on-site and automatic measurements are therefore being developed. A major goal of this book is to evaluate the 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.
This book also includes

• critical discussion of the state of the art of existing techniques and devices,
• what can be expected in terms of performance and
• possible improvements in the future.

In Situ Monitoring of Aquatic Systems will thus be invaluable to both researchers interested in the development of environmental monitoring systems and laboratories in charge of water quality assessment by proving them with a critical evaluation of existing and possible future options. Indeed it will be a valuable reference book for any researcher interested in developing new types of sensors for in situ monitoring.
