Application of silver-based biocides in face masks intended for general use requires regulatory control

Presenter: Jan Masta (Sciensano)

Abstract: Silver-based biocides are applied in face masks because of their antimicrobial properties. The added value of biocidal silver treatment of face masks to control SARS-CoV-2 infection needs to be balanced against possible toxicity due to inhalation exposure. Direct measurement of silver (particle) release to estimate exposure is problematic. Therefore, this study optimized methodologies to characterize silver-based biocides directly in the face masks, by measuring their total silver content using ICP-MS and ICP-OES bas   read more...

Comparison of biodistribution of cerium oxide nanoparticles after repeated oral administration by gavage or snack in Sprague Dawley rats

Presenter: Alicja Mortensen (The National Research Centre for the Working Environment)

Abstract: The rate of translocation of ingested nanoparticles (NPs) and how the uptake is affected by a food matrix are key aspects of health risk assessment. In this study, female Sprague Dawley rats (N=4/group) received 0, 1.4, or 13 mg of cerium oxide (CeO2 NM-212) NPs/rat/day by gavage or in a chocolate spread snack 5 days/week for 1 or 2 weeks followed by 2 weeks of recovery. A dose and time-dependent uptake in the liver and spleen of 0.1–0.3 and 0.004–0.005 parts per million (ng/mg) of the total administered dose was f   read more...

A Walk in PARC WP Hazard Assessment

Presenter: Philip Marx-Stoelting (Germand Federal Institute for Risk Assessment)

Abstract: Current approaches for the assessment of environmental and human health risks due to exposure to chemical substances have served their purpose reasonably well so far. Nevertheless, the assessment systems in place for different chemical regulations are faced with several challenges, ranging from a growing number of chemicals to changes in the types of chemicals and materials produced. This has triggered awareness of the need for a paradigm shift, notably appearing in the CSS, requiring new concepts for chemical risk a   read more...
