Risk assessment of surfactants in coastal environments

Acronym: RISICO
Period: 2004 till 2008
Status: Completed

Institutes (2)  Top 
  • Université Libre de Bruxelles; Faculté des Sciences; Laboratoire de physiologie et d'Agrotechnologie végétale (LAV), more, partner
  • Procter & Gamble Eurocor N.V., more, co-ordinator

The objective of the RISICO project is to develop analytical methods to predict the exposure to surfactant mixtures in sea-sprays and in marine sediments and their effects on coastal ecosystems.
The innovative aspects include the development and validation of

  1. specific analytical methods targeting surfactants in sea sprays,
  2. a radiotracer approach to characterize kinetics of surfactants biological uptake and subsequent metabolization in target marine organisms,
  3. insight into the bioavailability and sorption of surfactants in marine sediments,
  4. a microbiofilm in stratified oxic/anoxic sediments to identify recalcitrant metabolites, and
  5. new standardized ecotoxicity tests for marine sediments.
