Toxic Metals Found in Many Plastic Toys Sold in Brazil, New Study Warns
A new study has uncovered worrying levels of toxic metals in many plastic toys sold in Brazil. The research team analyzed 70 products and found contamination in most samples. As a result, experts are urging stronger safety checks and better manufacturing oversight.The study examined toys made both locally and overseas. It stands as the most detailed investigation of chemical risks in children’s toys in Brazil so far.
High Levels of Barium, Lead, and Other Metals
The results showed extremely high levels of hazardous substances. For example, almost half of the toys contained barium above legal limits. Some items had levels up to 15 times higher. Barium exposure can cause heart issues, muscle weakness, and serious neurological problems.The team also detected concerning amounts of lead, chromium, and antimony. Lead exceeded safe limits in nearly one-third of the samples. This metal can harm a child’s brain and reduce learning ability. Chromium and antimony also appear in many toys and may trigger long-term health problems.
How Researchers Tested the Toys
Scientists used advanced technology to identify the contaminants. They relied on inductively coupled plasma mass spectrometry, which detects even tiny amounts of metals. In addition, they performed tests that mimic contact with saliva to understand exposure risks.The tests showed that only a small fraction of each toxin is released during oral contact. However, the total amount inside many toys remains very high. Therefore, experts believe the overall risk still deserves serious attention.
Clues About Manufacturing Sources
The researchers also found patterns that may help identify where the contamination begins. For example, they noticed similar metal combinations in several toys, which points to shared production processes. Beige-colored toys showed higher contamination, possibly due to specific paint suppliers.The findings highlight the need for stronger regulations. In addition, the researchers call for frequent lab testing and stricter certification, especially for imported items.
