چکیده
Abstract Diclofenac is a nonsteroidal anti-inflammatory human and veterinary medicine widely detected in European surface waters, especially downstream from Wastewater Treatment Plants (WWTPs). Veterinary uses of diclofenac Europe are greatly restricted, so wastewater the key exposure route for wildlife. Proposed Environmental Quality Standards (EQS) which include an assessment toxicity to aquatic organisms under consideration by Commission (EC) support aims Water Framework Directive (WFD). The EC approach favours use deterministic (single test value factor) derivation direct EQS diclofenac, resulting 0.040 µg L ?1 based on single mesocosm study. In this paper, we discuss potential issues with respect EC’s own guidance derive evidence-driven alternative 0.126 using probabilistic (species sensitivity distribution) that accounts all reliable relevant data accordance guidance. Europe-wide freshwater monitoring used indicative compliance EQS. implications only some does not adhere guidance, compared guidance-compliant available also discussed.
