A University of Cape Town (UCT) study has uncovered traces of banned toxic chemicals in various children's products sold in South Africa, raising serious concerns about product safety.

The research, led by PhD candidate Rebecca Mlelwa under the supervision of Prof Andrea Rother, tested 138 new and second-hand items including Rubik’s Cubes, toy phones, puzzle mats, sunglasses, car seats, and toys.

Using X-ray fluorescence spectrometry, researchers detected bromine in 38% of products and antimony in 90%, both linked to legacy flame-retardant chemicals banned globally due to health risks like endocrine disruption and cancer.The findings suggest contaminated recycled plastics are reintroducing these hazardous substances into children’s products.

Mlelwa warned that while recycling is vital, it must not compromise child safety, as young bodies are more vulnerable to toxic exposure through skin contact, ingestion, or dust inhalation.

The study calls for stricter regulations, mandatory product testing, and transparency in chemical use to prevent harmful substances from entering the market.This adds to global evidence highlighting the need for stronger safeguards in circular economy practices to protect public health.
