Potentially harmful chemicals found in plastic toys
...
"Out of 419 chemicals found in hard, soft and foam plastic materials used in children toys, we identified 126 substances that can potentially harm children's health either via cancer or non-cancer effects, including 31 plasticizers, 18 flame retardants, and 8 fragrances. Being harmful in our study means that for these chemicals, estimated exposure doses exceed regulatory Reference Doses (RfD) or cancer risks exceed regulatory risk thresholds. These substances should be prioritized for phase-out in toy materials and replaced with safer and more sustainable alternatives," says Peter Fantke, Professor at DTU Management and the study's principle investigator.
Nicolò Aurisano, the study's first author and Peter's PhD student, explains that toy manufacturers usually do not provide any information on the chemical content in the toys, and toy composition databases are missing. Hence, the researchers had to collect and scrutinize information on chemicals contents in toy materials based on chemical test data for specific toys reported in 25 different peer-reviewed studies.
Nicolò further states: "We have combined the reported chemical content in toy materials with material characteristics and toy use patterns, such as how long a child typically plays with a toy, whether it puts it into the mouth, and how many toys are found in a household per child. We used this information to estimate exposure using high-throughput mass-balance models, and compared exposure doses with doses below which there is no unacceptable risk to the children."
The researchers find that children in Western countries have on average about 18 kilograms of plastic toys, which underlines the large amounts of plastic that children are surrounded by on a daily basis.
