Scientists from the University of Gothenburg studied the composition of 157 plastic children’s toys. Some were made before 2014, when restrictions on permitted toy composition were adopted. Unhealthy phthalates and chlorinated paraffins were found in concentrations exceeding the permissible norm in 84% of the old products and 30% of the new ones.
Therefore, in many old balls, the phthalate concentration was more than 40% of the weight of the toy. And this is 400 times higher than the allowable level.
Additionally, scientists have concluded that recycling toys is impractical because this way dangerous chemicals can get into new toys.
