摘要

This paper discusses the need for regulatory measures to include persistence and mobility of chemicals as hazard criteria to better protect freshwater, groundwater and drinking water. In the EU, the hazard criteria persistence and mobility are, regulatorily speaking, still new. These criteria have been included in environmental hazard classes in Regulation 1272/2008 on classification, labelling and packaging of substances and mixtures in 2023 (Commission Delegated Regulation 2023/707). Even though these substances may not be classified as toxic under existing criteria, their persistence and mobility pose potential hazards to the environment and human health. We show the perspective of the German stakeholder dialogue on trace substances and how chemicals are assessed in this national framework. Persistence and mobility criteria should also be integrated into regulatory approaches, namely the derivation of environmental quality standards for surface water and in the hazardousness definition of the Urban Wastewater Treatment Directive 2024/3019. To ensure regulatory consistency, we support harmonized criteria as laid down in Regulation 2023/707 for persistent and mobile substances across different legislative frameworks.
