With different legislations including or aiming to include limits for either specific or sets of PFAS, it is needed to accurately and precisely confirm their absence/ presence in aqueous environments. A set of ‘official’ methods are available, albeit often accompanied by some uncertainties on their […]
In 2018 the dermal Advanced REACH Tool (dART) was developed, calibrated and published (Goede 2018, McNally 2019), initiated by the Health and Safety Executive (UK) and the Dutch Ministry of Social Affairs and Employment. The dART has been developed as an extension to the ART model and involves a new mechanistic Tier 2 exposure model for estimating dermal […]
Simulation tests in surface water, soil, and aquatic sediment systems are considered higher tier tests in regulatory persistence assessments. They investigate biodegradation under more realistic environmental conditions, such as the use of natural inocula and lower test substance concentrations, and can generate compartment-specific biodegradation […]
The first comprehensive assessment of adsorption and desorption characteristics of water soluble polymers (WSPs) and water dispersible polymers (WDPs) to mineral surfaces for environmental fate assessment was recently published by the group of the principal investigator (Sanders et. al) . […]
The FRAGMENT-ARTICLE project will identify key formulation factors that impact the degradation and fragmentation into micro- and nanoplastics of post-use plastic articles in the environment. It will build a quality dataset on the influence of product formulation, use this to […]
The overarching goal is to test the hypothesis that in some situations new approach method (NAM)-based assessments bear less uncertainty whereas in others, animal-data based assessments will have less uncertainty. To achieve such, the specific project objectives include: Performing probabilistic […]
The project will deliver a new version of UTOPIA that will integrate state-of-the-science knowledge about the behavior of microplastic in the environment and support calculation of exposure metrics and representative concentrations of microplastic to support risk assessment.
We propose a project to publish a paper that more fully explores the uncertainty and variation in MAF values for mixtures that occur in surface waters. The objectives of the second paper are to clearly describe the biases in the […]
The general objective of this project proposal is therefore to develop a probabilistic modelling framework that allows to identify the priority chemicals for co-exposure risk at the watershed level. The environmental fate model at the core of this probabilistic framework […]
This research project aims to investigate the current understanding of the risk of dermal uptake of MNPs. Information on the impact of particle size, shape (spherical, needle, irregular, fibre), polymer composition, hydrophobicity, charge, surface chemistry and aging will be investigated […]
