This commentary explores the use of high-resolution data from new, miniature sensors to enrich models that predict exposures to chemical substances in the workplace. To optimally apply these sensors, one can expect an increased need for new models that will facilitate the interpretation and extrapolation of the acquired time-resolved data. We...

Driven by the concept of the ‘four generations of nanomaterials’, the current state of the knowledge on risk assessment of future generation is explored for active nanomaterials. Through case studies, we identify challenges and evaluate the preparedness of characterization methods, available risk assessment modeling tools, and analytical...

Model tools for estimating hazardous substance exposure are an accepted part of regulatory risk assessments in Europe, and models underpin control banding tools used to help manage chemicals in workplaces. Of necessity the models are simplified abstractions of real-life working situations that aim to capture the essence of the scenario to give...

Measured data are generally preferred to modelled estimates of exposure. Grouping and read-across is already widely used and accepted approach in toxicology, but an appropriate approach and guidance on how to use existing exposure measurement data on one substance and work situation for another substance and/or work situation is currently not...

Nederland is in ontwikkeling. Onder invloed van globalisering, een stijgende levens verwachting en technologisering verandert onze demografie en onze arbeidsmarkt. Ook het karakter van werk verandert sterk in de komende decennia. Flexibilisering, de komst van nieuwe technologie en intensivering van het werk zijn hierin leidend, aldus de WRR in...

The challenge in ensuring the safety of manufactured nanomaterials and products stems from the lack of knowledge among industries about the potential environment and health risks of nanotechnology based innovations and the legislations that apply to them. A lack of information and preparedness for the regulatory safety assessment of innovative...

The current work describes the interaction with various stakeholder groups to establish consensus on stage-gate specific criteria that human risk assessment (HRA) models for manufactured nanomaterials (MN) need to comply with. During the decisive steps in the innovation process, which can be described in a simplified way as stage-gates, it is...

For many work situations only insufficient exposure data are available to perform proper risk assessment. Because measuring worker exposure can be time consuming and resource intense, the availability of reliable exposure models is important when performing risk assessments. However, the development and improvement of exposure models are...

Dustiness is not an intrinsic physically defined property of a powder, but the tendency of particles to become airborne in response to mechanical and/or aerodynamic stimuli. The present study considers a set of 10 physical properties to which the powder dustiness can be attributed. Through a preliminary investigation of a standardized continuous...

This article describes the development of a mechanistic model for underpinning the dermal Advanced REACH Tool (dART), an extension of the existing ART model and its software platform. It was developed for hand exposure to low volatile liquids (vapour pressure ≤ 10 Pa at 20°C) including solids-in-liquid products. The model is based on an existing...
