This book is the result of a research project on environmental behaviour of sediments. It represents one of the most comprehensive programs in the field of chemical and biological interactions of toxicants in sediments. It also provides valuable insights into the actual international state of sediment quality assessment and discusses various chemical and biological approaches to sediment toxicity. The understanding of interactions of toxic substances in sediments and of conditions controlling mobilization, transfer and bioavailability can be used to predict environmental fates and effects of chemicals. Such knowledge is essential to explain the limitations of existing water quality regulations and will help to set up appropriate sediment quality criteria. Inglés
