The joint initiative of the European detergent and surfactant industries (A
ISE, CESIO), called ERASM, was founded in 1991 as a response to the ongoing
risk assessment activities in Europe. The activities of ERASM aim at a sci
entifically sound environmental risk assessment of surfacfants used in dete
rgents and involve work by industry expert groups as well as environmental
research programmes sponsored by industry. The goals include programmes to
improve the existing tools for risk evaluation and to enlarge knowledge abo
ut the fate and impact of surfactants in environmental compartments. The ER
ASM activities in recent years have focussed on the development of GREATER,
a sophisticated calculation model allowing a visualised prediction of Chem
icals concentration along a river, and on in-depth studies into the bioconc
entration behaviour as well as the terrestrial fate and effects of importan
t surfactant groups. Major contributions have also been made to an improved
understanding of the role of surfactants in anaerobic environments, their
influence on artificial river ecosystems and their possible impact to river
s receiving untreated waste waters. The paper will review the background an
d summarise the achievements of and the conclusions from these ERASM activi
ties.
