AbstractBackgroundExisting models for estimating children’s exposure to chemicals through mouthing currently depends on the availability of chemical- and material-specific experimental migration rates, only covering a few dozen chemicals.ObjectiveThis study objective is hence to develop a mouthing exposure model to predict migration into saliva, mouthing exposure, and related health risk from a wide range of chemical-material combinations in children’s products.MethodsWe collected experimental data on chemical migration from different products into saliva for multiple substance groups and materials, identifying chemical concentration and

The Secretariat of the Strategic Approach to Chemicals Management (SAICM) and the University of Cape Town (UCT) have established a Community of Practice (CoP) on Lead in Paint to bring representatives from different sectors together and to create a learning network around issues related to the elimination of Lead Paint. This is a summary of the discussion on Making the case: raising awareness about importance of lead paint laws, which took place on 14 September 2021.Presenters: Lesley Onyon (WHO), Siddika

Scientific knowledge to assess the exposure to nanomaterials continues to improve. The OECD compiled an inventory of available models and tools for assessing occupational, consumer and environmental exposure to Nanomaterials. 54 tools and models were initially compiled and following in-depth analyses, 10 occupational, 7 consumer and 6 environmental tools/models were recommended or evaluated as suitable for assessing exposure to nanomaterials. The detailed information on the analyses and evaluations are provided in the reports accessible from the Series on Nanomaterials website

The SAICM Secretariat, in partnership with the University of Cape Town, established a community of practice on Chemicals in Products to bring representatives from different sectors together and to create a learning network around issues related to addressing Chemicals in Products (CiP). This is a summary of the discussion on Traceability in the textiles value chain, which took place on 11 November 2021.Presenters: Ahmad Ansari (ZDHC)Traceability in the textile values chain refers to the ability to trace a product’s lifecycle

Chemicals provide a variety of specific functions in electric and electronic products or in their manufacturing process. However, some of these chemicals are hazardous and can cause concern related to their potential for adverse impacts on human health and the environment. Such impacts can occur throughout the product’s life cycle, including raw material extraction, processing and manufacturing, but also during product use or at end-of-life. However, decisions influencing product ingredients are usually taken at upstream stages of the value chain

PFAS are non-aromatic, organic chemicals in which the hydrogen atoms in the carbon chain are fully replaced (“per”) or partly but almost entirely replaced (“poly”) by fluorine atoms. At least 4,700 substances belong to this group of substances. All these chemicals have in common that their environmental degradability is fairly slow and very limited and therefore remain resistant for years to decades.PFAS are “forever chemicals.” Even when being incinerated for disposal, very high temperatures are required for these compounds to

The Secretariat of the Strategic Approach to Chemicals Management (SAICM) and the University of Cape Town (UCT) have established a Community of Practice (CoP) on Lead in Paint to bring representatives from different sectors together and to create a learning network around issues related to the elimination of Lead Paint.
