ECO21-ARC: Improving the performance and expanding the applicability of a mechanistic bioconcentration model for ionogenic organic compounds (IOCs) in fish (BIONIC)
The general objective of this proposed research is to improve the mechanistic understanding of bioaccumulation of ionogenic organic chemicals (IOCs) in aquatic organisms, primarily fish, in the form of mass balance models and to increase the confidence of applying these […]

B10-ICL: Animal and human NOAELS: cross-species comparison, inference and synthesis
The overall aim of the proposed project is to provide a systematic and quantifiable comparison of NOAELs derived from animal studies with those from human studies for a range of chemicals and to develop robust evidence synthesis (meta-analytical) methodology combining […]

B9-VITO: DRESS – DeRmal Exposure aSsessment Strategies
The use of chemicals in consumer products has been, and still is, of great societal importance. Their use allowed industry to achieve a high level of innovation, as well as greatly improve the quality of day-to-day life of many consumers. […]

HBM4-VITO:Understanding inter- and intra-individual variability in HBM spot samples
In many large-scale human biomonitoring (HBM) surveys, single samples of blood, urine or other bodily matrices are collected from large numbers of individuals recruited from the general population. These HBM surveys aim to obtain information on the distribution of exposures […]

ECO18-Eawag: Improved strategy to assess chemical persistence at the water-sediment interface
In this project, we intend to investigate two hypotheses that should (i) help better understand the value and information content of the existing OECD 308 protocol, and (ii) help develop an improved test strategy for assessing persistence in sediment and […]

B7-ETHZ: Estimation of realistic consumer exposure to substances from multiple sources and approaches to validation of exposure models
This project will provide a short overview on existing methods for estimating aggregate consumer exposure, i.e. exposure that adds up from consuming different household consumer products, and is built upon the work that is already funded by LRI in response to […]

B8-FRAU: Threshold of Toxicological Concern (TTC) for inhalation exposure: Improvement of the TTC concept for inhalation exposure and derivation of thresholds with the database RepDose
Recent results of the analysis of Cramer classes for inhalation studies indicate that local effects of the respiratory tract and eyes dominate the very low NOEC values in Cramer class 1 and also to some extent in class 3 and […]

ECO17-WAG: Evaluation of test methods for measuring toxicity to sediment organisms
The primary aim of this project is to develop improved methods for assessing potential effects of contaminated sediments on aquatic microorganisms, plants and invertebrates within and across different taxonomic groups, to be applied in a regulatory context such as REACH. The objectives […]

ECO6.2-CSL: Establishing relationships of biotransformation across organisms
The overall aim of this study is to develop quantitative structure-activity relationships relating to biodegradation, biotransformation and bioaccumulation in organisms from different taxa and trophic levels and to develop relationships between biotransformation in microbial systems, invertebrates and vertebrate species. This […]

ECO6.2-ILSIHESI: Pre-validation of an in vitro fish liver S9 assay to optimize the prediction of bioaccumulation
The specific objectives of this project are to support incorporation of in vitro metabolism data into BCF prediction models and to extrapolate in vitro test results to whole body biotransformation rates (kmet) to be used to refine BCF model predictions. […]
