A recent study by the University of Cape Town, published in the journal Heliyon, has revealed that various children's products sold in South Africa contain traces of banned toxic chemicals. Researchers Rebecca Mlelwa and Professor Andrea Rother examined 138 new and second-hand items, including Rubik’s Cubes, puzzle mats, and car seats, using X-ray fluorescence spectroscopy. The study found bromine in 38% of products and antimony in 90%, suggesting that legacy pollutants are re-entering the market through contaminated recycled plastics. These brominated flame retardants are linked to cancer, neurotoxicity, and endocrine disruption. Because children are highly vulnerable to these toxins through skin contact or mouthing toys, researchers warn that recycling processes must include stronger safeguards. The team advocates for a coordinated response from South African regulatory bodies to enforce stricter testing and transparency to prevent these hazardous substances from circulating in consumer goods.
