Sea Baby Ball, also known as water sprite, Bawangzhu and Crystal Baby, is a kind of water drop with different colors and the size of soybean. After soaking in water, it will expand several times, and it will break when pinched. Many people should have played it.
However, it is actually a kind of super absorbent polymer material. The reason why it can expand rapidly after absorbing water is mainly because most of it is a composite material of sodium polyacrylate, which contains toxic elements such as benzene, lead, magnesium, manganese and boron, and bright colors need more additives.
Analysis and Testing Center of Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences: After elemental analysis, it is found that Haibao contains magnesium, zinc, titanium, manganese, boron, barium, chlorine, sulfur and other elements. These chemical elements and their compounds are toxic and harmful to human body.
At the same time, the chloroform extract of "Haibao" was detected, and it was found that it contained aromatic compounds with benzene rings or heteroaromatic rings. According to the characteristics of water absorption, swelling and certain elasticity of colored balls, it is determined that the main component of colored balls is hydrophilic resin through inspection. Whether skin contact (infiltration) or inhalation of its volatile substances may be harmful to children's health.
suggestion
Experts suggest that relevant departments should carry out relevant tests on sea babies according to toy safety standards.
"This kind of toy definitely does not meet the requirements." The relevant person in charge of Shanghai Toy Association said that the General Administration of Quality Supervision, Inspection and Quarantine and the National Certification and Accreditation Administration (CNCA) have implemented "3C" compulsory product certification for six types of toy products, including plastic toys, metal toys, ejection toys and doll toys, since March, 2006. The "three noes" products like "Sea Baby" should be produced by some small workshops. He suggested that the relevant departments should deal with the production of this "three noes" toy.
