Surface Water Photochemistry [PDF ebook] 

Borne out of the current widespread interest in the pollution of water bodies, this book explores the latest research concerning the photochemical fate of organic pollutants in surface water. Considering both the functioning of ecosystems and the behaviour of emerging pollutants in those ecosystems, it is dedicated to techniques that can be used in the field and in the laboratory for the detection of pollutants and of their transformation intermediates. The inclusion of photochemical processes that have not gained previous coverage will afford the reader novel insights, whilst the focus on modelling and transformation intermediates will ensure the title’s relevance to academics, the chemical manufacturing industries and environmental assessment experts alike.
