Abstract

ABSTRACT This article describes the current state of the development toward a common European framework for site-specific ecological risk assessment (SS-ERA) Although common progression has been slow in the past two years, earlier activities were very promising. Results are presented of a 2001 workshop to discuss the scientific development and policy needs in preparation of such a common framework. The framework was recommended to follow a tiered approach. Other important elements for a common European framework for SS-ERA were identified to be the use of generic values in the first tier and bioassays in later tiers, to address bioavailability in the assessment, to differentiate for land use. Also, the framework should allow for negotiation between stakeholders specific to the site. These aspects are present in the Dutch approach to SS-ERA, and this article further presents some experience with the application of this framework in a large case of SS-ERA in The Netherlands. The derivation of suitable ecological parameters and assessment criteria in view of land use in a tiered approach risk assessment is focused on, and the interactive process between stakeholders and ongoing discussions concerning references and criteria for assessment are illustrated.
