ECO36: Paving the way for QIVIVE – from nominal to free to cellular concentrations in in vitro assays

The objective of this project is to bundle existing expertise to progress exposure assessment in in vitro bioassays used for high-throughput screening (HTS) in 384- and 1536-well plates and complex in vitro bioassays based on transwell and 3D cultures.

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 […]

ECO33: Use And Interpretation Of Dietary Bioaccumulation Tests For Hydrophobic

The overall objective of the proposed research is to improve the interpretation of dietary bioaccumulation tests for hydrophobic chemicals.

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 […]

ECO32: Environmental risk assessment of poorly soluble substances: Improved tools for assessing biodegradation, (de)sorption, and modeling

This project proposal will answer the following questions: Objective: How can the aqueous phase biodegradation kinetics of poorly water soluble substances be measured without the influence of bioavailability factors, i.e., without (de)sorption effects? Objective: How can the desorption rates of […]

ECO31: Identifying strategies that will provide greater confidence in estimating the degradation rates of organic chemicals in water, soil and sediment

In the first phase of this project (ECO31.1), the team aimed to identify strategies that will provide greater confidence in estimating the degradation rate constants of organic chemicals in the environment. To meet this objective, the team performed an extensive […]

B18: Carcinogen Dose-Response Database for Threshold of Toxicological Concern (CDRD-TTC)

This project aims to generate a fully-curated, quality-controlled and publically-available database on genotoxic and non-genotoxic carcinogens. The novel database will form the basis of analysis of TTC distributions for cancer thresholds. The specific objectives of the research, in the context […]
