The Secretariat of the Strategic Approach to Chemicals Management (SAICM) and the University of Cape Town (UCT) have launched a Community of Practice (CoP) on Chemicals and SDGs to bring representatives from different sectors together and to create a learning network around issues related to addressing Chemicals and the Sustainable Development Goals (SDGs). This is a summary of the discussion on Plastic pollution: ideas for addressing chemicals in plastics, which took place on 19 October 2022.

Presenters: Brenda Koekkoek (UNEP), Jost Dittkrist (UNEP), Dr. Eeva Leinala (OECD), Mochamad Adi Septiono (Nexus3 Foundation)

In this report, we present a list of Chemicals of Concern (CoCs) in plastic toys, with supporting information on the applied selection criteria. To identify the CoCs, we started from a literature review of available plastic toys compositions studies, and obtained the chemical mass fraction in plastic toy as well as the chemical functions. The chemical emissions from the plastic toys and subsequent human exposures were then estimated using a series of models and the coupled nearfield and far-field exposure assessment framework. Finally, the human exposure doses were compared to toxicity measures such as the reference dose (RfD), or median effective dose (ED50) for cancer effects, to evaluate the health risks on children. Chemical-material combinations that have a hazard quotient (HQ) > 10, a margin of exposure (MoE) < 100, or a lifetime cancer risk > 10-6 were included in the list of CoCs. In total, 35 (less than 10%) of all chemical-material combinations studied were identified as CoCs. The results indicate that a relevant amount of chemicals used in plastic toys may pose a non-negligible health risk to children, calling for more refined investigations and more human- and eco-friendly alternatives.
