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.
