ECO37: D-BASS – Developing a Bioaccumulation Assessment Strategy for Surfactants

The general objective of this proposed research is therefore to validate the combined use of (a) measured partition coefficients, (b) in vitro intrinsic hepatic clearance rates, and (c) a recently improved bioaccumulation model for ionogenic compounds, against measured bioconcentration factors […]

ARC3: Development of The Bioaccumulation Assessment Tool (BAT Ver.1.0) to Aid in the Bioaccumulation Assessment of Organic Chemicals

This project aims to develop a user-friendly organizational framework and computational tool in the form of an Excel spreadsheet for integrating various lines of evidence in a quantitative weight of evidence (QWOE) approach to aid regulatory decision-making for bioaccumulation assessment.

B19: Extrapolating the Applicability of Worker Exposure Measurement Data

The purpose of this project is to develop criteria and examples (case studies) that can be applied to evaluate if exposure measurements for a given substance(s) and use scenario(s) might be reasonably representative for another substance used in the same […]

AIMT8: Prediction of systemic toxicity after repeated exposure by new approach methodologies (NAMs) – is prediction of STOR-RE classification possible?

This project aims to assess the ability of currently available new approach methodologies (NAM) to predict STOT-RE categories of a range of chemicals for which both in vitro and in vivo data are available and that can be profiled in […]

ECO35: Interference of hepatotoxicity with endocrine activity in fish

The project proposed is driven by the hypothesis that hepatotoxicity may positively or negatively interfere with vitellogenin production, which is used as a key marker of endocrine activity in current OECD test guidelines 229, 230 and 234 and the proposed […]

ECO20.2: Development of an alternative testing strategy for the fish early life-stage test for predicting chronic toxicity: assay validation

This project demonstrates the use of in chemico assays targeting specific key events of an established Adverse Outcome Pathway (AOP) to predict higher biological endpoints. One of the case studies in this project focused on the role of thyroid hormones […]

ECO34: A tiered testing strategy for rapid estimation of bioaccumulation by a combined modelling – in vitro testing approach

The overall objective of our research is to reduce the uncertainty related to the estimation of bioaccumulation of organic chemicals in fish in ecological risk assessment (ERA). Based on a combination of different in vitro approaches to estimate chemical uptake […]
