An environmental risk assessment has been carried out for the polycyclic musks AHTN and HHCB according to the EU Technical Guidance Document for Environmental Risk Assessment for New and Existing Substances. AHTN and HHCB are used in fragrances for cosmetics and detergents. Both substances are high volume chemicals with a use volume for Europe of 585 and 1482 tonnes in 1995, respectively. The environmental risk assessment is based on information and results of studies provided by the fragrance industry as represented in the Netherlands by its association of Fragrance and Flavouring Materials Manufacturers (NEA), and the Research Institute for Fragrance Materials (RIFM) and international literature sources as well. Endpoints in the assessment were aquatic organisms, sediment dwelling organisms, soil organisms, fish-eating predators and worm-eating predators. Predicted Environmental Concentrations (PECs) were calculated with the European Union System for the Evaluation of Substances (EUSES). Since monitoring data were available for several media, measured concentrations could be compared with predicted ones. Subsequently, one of the two was selected as the exposure concentration used for the risk characterisation.
