In Climate Change and Marine and Freshwater Toxins the editors have assembled contributions from a team of international experts to expand the framework for an appropriate assessment of climate change impacts on aquatic toxins. While the production of toxins by microalgae has been known for decades, establishing a factual link supported by scientific evidence is a very complex endeavor. The increasing frequency and distribution of toxic blooms for example continue to raise serious concerns regarding seafood and drinking water safety. This book compiles current evidence on the influence of climate change on the spreading of toxin producing species in aquatic systems. The chemistry and biology of toxin production is revised and an outlook on control and prevention of the toxin's impact on human and animal health is given. * Compelling quantitative evidence of complex interactions from primary toxin producers and along the food chain. * Latest advances on prediction and prevention of water toxin threats to human and animal health. * A must read for insights into aquatic toxins and their modification by climatic conditions.
