De toekomst van gezond en veilig werken een brede horizonscan

Het RIVM en TNO hebben onderzocht wat de impact is van ontwikkelingen in de komende 20 jaar op gezond en veilig werken. Hoe beïnvloedt artificiële intelligentie onze veiligheid op het werk? Wat betekent de energietransitie voor de risico’s waaraan werkenden blootgesteld worden? Direct of indirect hebben dit soort ontwikkelingen invloed op de...

Safe innovation approach: Towards an agile system for dealing with innovations

Nanotechnologies are characterized by a growing legacy of already marketed and novel manufactured nanomaterials (MNMs) and nano-enabled products with a lack of a coherent risk governance system to address their safety effectively. In response to this situation, a proactive system is needed to minimize the gap between the pace of innovation and...

Understanding workers' exposure: Systematic review and data-analysis of emission potential for NOAA

Exposure assessment for nano-objects, and their aggregates and agglomerates (NOAA), has evolved from explorative research toward more comprehensive exposure assessment, providing data to further develop currently used conservative control banding (CB) tools for risk assessment. This study aims to provide an overview of current knowledge on...

A new approach combining analytical methods for workplace exposure assessment of inhalable multi-walled carbon nanotubes

To date there is no consensus about the most appropriate analytical method for measuring carbon nanotubes (CNTs), hampering the assessment and limiting the comparison of data. The goal of this study is to develop an approach for the assessment of the level and nature of inhalable multi-wall CNTs (MWCNTs) in an actual workplace setting by...

Assessment of Determinants of Emission Potentially Affecting the Concentration of Airborne Nano-Objects and Their Agglomerates and Aggregates

Background: Nano-specific inhalation exposure models could potentially be effective tools to assess and control worker exposure to nano-objects, and their aggregates and agglomerates (NOAA). However, due to the lack of reliable and consistent collected NOAA exposure data, the scientific basis for validation of the existing NOAA exposure models...

Evaluation of Decision Rules in a Tiered Assessment of Inhalation Exposure to Nanomaterials

Tiered or stepwise approaches to assess occupational exposure to nano-objects, and their agglomerates and aggregates have been proposed, which require decision rules (DRs) to move to a next tier, or terminate the assessment. In a desk study the performance of a number of DRs based on the evaluation of results from direct reading instruments was...

Potential Release of Manufactured Nano Objects during Sanding of Nano-Coated Wood Surfaces

Increasing production and applications of manufactured nano objects (MNOs) have become a source for human exposure and therefore raise concerns and questions about the possible health effects. In this study, the potential release of nano objects, their agglomerates, and aggregates (NOAA) as a result of sanding of hardwood treated with MNOs...

The validity and applicability of using a generic exposure assessment model for occupational exposure to nano-objects and their aggregates and agglomerates

Background: Control banding can be used as a first-tier assessment to control worker exposure to nano-objects and their aggregates and agglomerates (NOAA). In a second tier, more advanced modelling approaches are needed to produce quantitative exposure estimates. As currently no general quantitative nano-specific exposure models are available,...

Analysis of time series of particle size distributions in nano exposure assessment

Occupational exposure to nano-objects and their agglomerates and aggregates across various life cycle stages: A broad-scale exposure study

Human exposure to conventional and nanoparticle-containing sprays - A critical review

The release of pesticides from conventional spray products has been investigated in depth, and suitable analytical techniques detecting the mass of the released substances are available. In contrast, nanoparticle-containing sprays are less studied, although they are perceived as critical for consumers because inhalation exposure can occur to...

Field and Laboratory Measurements Related to Occupational and Consumer Exposures

Airborne manufactured nano-objects released from commercially available spray products: Temporal and spatial influences

This paper reports a study of the dispersion of manufactured nano-objects (MNOs) through the air, both in time and space, during the use of two commercially available nano-spray products and comparable products without MNOs. The main objective was to identify whether personal exposure can occur at a greater distance than the immediate proximity...

NanoNextNL: Meetstrategie voor het meten van nanomaterialen op de werkplek

Industrial Production and Professional Application of Manufactured Nanomaterials-Enabled End Products in Dutch Industries: Potential for Exposure

Background: In order to make full use of the opportunities while responsibly managing the risks of working with manufactured nanomaterials (MNM), we need to gain insight into the potential level of exposure to MNM in the industry. Therefore, the goal of this study was to obtain an overview of the potential MNM exposure scenarios within relevant...
