Spotlight September: A methodology for the automatic evaluation of data quality and completeness of nanomaterials for risk assessment purposes
This paper describes a method for automatically assessing the quality and completeness of nanosafety data for the purpose of risk assessment. Steps to develop the methodology for assessing data completeness and the methodology for assessing quality are presented. The methodology is tailored to physicochemical and hazard (meta) data, but can also be configured with appropriate criteria to support modeling or exposure assessment. It is based on assessing the quality and completeness of the data contained in the eNanoMapper database using the harmonized data reporting templates introduced in the NANoREG project and further developed in the GRACIOUS project. Combined with expert knowledge, this methodology can be used as a powerful data analysis tool in different contexts. To enable the practical application of the proposed methodology, it has been implemented as an online R-tool (https://shinyapps.greendecision.eu/app/gracious-data-quality) that can be connected to both databases and risk assessment software tools.

Spotlight August 2020: The nanoGRAVUR Grouping approach
In August, we would like to present a paper of the German BMBF project nanoGRAVUR. nanoGRAVUR dealt from 2015-2018 with the grouping of nanostructured materials with regard to occupational safety, consumer and environmental protection and risk mitigation. The approach is now described by the project partners in this paper.Due to the variety of synthetic nanomaterials and the numerous modifications (differences in size, shape, chemical composition and surface functionalization), the effort required to investigate effects and behaviour within the framework of regulatory requirements is…

The resistance of plants to various pathogens is often increased in agriculture with various chemicals (“fertilizers”). A new direction is being taken with the use of nanoparticles. These can be sprayed on the plants. In the present study, the model plant Arabidopsis was used to investigate whether silicon dioxide nanoparticles (SiO2) can increase resistance to […]

Plastic pollution has become a significant threat to the oceans, biodiversity, and ecosystems worldwide. Despite efforts to reduce plastic consumption, escalating plastic production continues to increase the magnitude of plastic pollution in the environment. In response to this crisis, the UN-Environmental Assembly (Link) adopted a resolution in March 2022 to develop a legally binding treaty […]

The European Commission has issued a ban on the colorant titanium dioxide in food. Titanium dioxide, which provides a nice shine and bright white color, can potentially damage genetic material. We chose a review article from 2022 for the May 2022 Spotlight that addresses the risk assessment of food-grade titanium dioxide (E171) and the resulting […]
