Even a decade after the Stockholm Convention on Persistent Organic Pollutants (POPs) was signed, a large variety of organic chemicals still pose ecological hazards of top most priority. The expansion of information base on organic pollutants (OPs), environmental fate and effects, as well as the cleansing methods, is accompanied by a rise in importance of certain pollution sources, associated with possible generation of new hazards for humans and nature. This book specifies these details, particularly in the light of Organic Pollutants risk assessment and analyzing methods of decontaminating our environment from Organic Pollutants. Providing an analytical and environmental update, this text can specifically be important for engineers and experts.
