Active pharmaceutical ingredients entering the aquatic environment from wastewater treatment works: A cause for concern?

October 23, 2017 by Dean Leverett

Dean has contributed to a recently published paper reporting on the variation in wastewater treatment works (WwTW) influent concentrations of a wide variety of active pharmaceutical ingredients (APIs), their removal efficiency, effluent concentrations and potential risks to the aquatic environment. The research is based on data generated from both Phase 1 and Phase 2 of the UKWIR CIP.

“Effects Based Tools” (EBT) and the Water Framework Directive (WFD)

March 13, 2017 by Becky Brown

There are currently 33 substances or groups of substances designated as priority substances (PS) under the WFD, for which environmental quality standards (EQSs) have been set and a further 8 substances with EQSs which are under the scope of Directive 86/280/EEC1. Good chemical status can only be achieved for a water body if concentrations of the PS are below their specific EQS. As part of the WFD review it has been suggested that the use of “effects based tools (EBT)” should be given consideration.

Workshop: Applying exposure science to increase the utility of non-animal data in the efficacy and safety testing

March 2, 2017 by Louise Youngs

Non-animal approaches can provide useful information on the mechanism of action, informing substance evaluation and product development. However, the regulatory applicability of these approaches is typically limited, as the relevance of in vitro concentrations to in vivo exposure, is often not considered.
