Notwithstanding the vast amount of environmental analytical chemical literature available, publications dealing with environmental analytical chemistry in a general, integrated manner are rather scant. In fact, most literature on such a relevant topic appears to touch on individual aspects such as water or air pollution, applicable conventional or special equipment used with given matrices and specific pollutant groups. Most of these books are of interest to experts and only a few, if any, provide less experienced readers with a systematic, comprehensive description of environmental analytical issues. This book, which is intended to fill the gap, approaches the subject by focusing on the sample and its handling.
