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 […]

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. […]

ART-TNO: Phase 1: mechanistic model and Bayesian update
Under REACH, the new chemicals policy in Europe, exposure scenarios form an essential basis for chemical risk assessment reports to show that chemicals can be used safely. This requires a tiered exposure assessment approach in which the first Tier is […]
