This book details the experiences gained by the Catalan Water Agency (ACA) in a Mediterranean watershed - the Catalan River Basin District - following the launch of the EU Water Framework Directive (WFD) in the year 2000. Experts in rivers, reservoirs, lakes, wetlands and estuaries present 13 chapters defining tools for water-status assessment specially adapted to Mediterranean conditions. The content of this and the companion volume Experiences from Ground, Coastal and Transitional Water Quality Monitoring: The EU Water Framework Directive Implementation in the Catalan River Basin District (Part II) are the result of an excellent collaboration between the ACA and several Catalan universities and research centers to cope with new challenges provided by the WFD monitoring requirements. The volume serves as a useful guide for environmental managers and scientists engaged in other European as well as Non-European river basins

Contamination of surface waters by pesticides continues to be the focus of concern for water authorities due to the growing evidence of their deleterious effects on aquatic life. In this context, the present work investigates the occurrence of 16 selected pesticides belonging to the classes of triazines, phenylureas, organophosphates, chloroacetanilides and thiocarbamates in surface waters from the Llobregat River (NE Spain) and some of its tributaries (Anoia and Rubí) and assesses their potential impact on the aquatic organisms by applying a recently developed index, the Short-term Pesticide Risk Index for the Surface Water System (PRISW-1), which takes into account the pesticides concentrations and their overall toxicity against three aquatic organisms (algae, Daphnia, and fish). Chemical analysis, performed by means of a fully automated method based on isotope dilution on-line solid phase extraction–liquid chromatography– electrospray–tandem mass spectrometry (on-line SPE–LC–ESI–MS/MS), revealed diuron and diazinon as the most ubiquitous and abundant compounds with levels up to 818 and 132 ng L 1, respectively. Total pesticide concentrations, which in only 1 out of 66 samples surpassed 500 ng L 1, were higher in the tributaries than in the river but their contribution in terms of mass-loads to the overall pesticide pollution of the Llobregat River was relatively small. Contamination increased downstream of the river and was clearly influenced by rainfall and hence river flow. Application of the PRISW-1 index indicated that, although pesticides levels fulfilled the European Union Environmental Quality Standards (EQS) for surface waters, the existing pesticide contamination poses a low to high ecotoxicological risk for aquatic organisms, that algae and macro-invertebrates are at higher risk than fish, and that the organophosphates diazinon and malathion and the phenylurea diuron are the major contributors to the overall toxicity and therefore the most problematic compounds. ; Peer Reviewed ; Postprint (published version)

This Workshop on "Safety assessment of consumer goods coming from recovered materials in a global scale perspective" is the first of the Thematic Workshops organized within the framework of the European Union (EU)-funded Coordination Action "Risk-based management of chemicals and products in a circular economy at a global scale" (RISKCYCLE). It was organised by the Dresden University of Technology (TUD), coordinator of the project, and by the Hanoi University of Science (HUS). The workshop was held from 4th–5th May 2010 in Hanoi, Vietnam ; Postprint (published version)

Abstract
Current prioritisation procedures under the EU Water Framework Directive (WFD) do not account for risks from chemical mixtures. SOLUTIONS proposes a multiple-lines-of-evidence approach to tackle the problem effectively. The approach merges all available evidence from co-exposure modelling, chemical monitoring, effect-based monitoring, and ecological monitoring. Full implementation of the proposed methodology requires changes in the legal text in adaptation to scientific progress.

Recently, the Guardian published an article entitled "EU clean water laws under attack from industry lobbyists" by Arthur Neslen (https://www.theguardian.com/environment/2019/may/15/eu-clean-water-laws-under-attack-from-industry-lobbyists) expressing concerns regarding a roll back in European clean water regulations. As principal investigators of the large EU-funded project "SOLUTIONS for present and future emerging pollutants in land and water resources management", we appreciate such an open debate on water quality protection in Europe, which we would like to enrich with conclusions from 5 years of extensive research and stakeholder dialogue within SOLUTIONS and other large EU projects. ; This article has been prepared as an outcome of the SOLUTIONS project (European Union's Seventh Framework Programme for research, technological development and demonstration under Grant Agreement No. 603437). ; Peer reviewed
