Toys are children’s close companions, and children share their joy with toys, and wear out their loneliness with toys. However, children do not know that toys are a good companion that can bring them deadly danger, and the killer is the lead that “lurks” in toys. Lead is currently recognized as one of the environmental toxins that affect the development of the central nervous system. Children’s gastrointestinal absorption rate of lead is about 5 times higher than that of adults, and because children’s central nervous system is not fully developed, they are more sensitive to the toxicity of lead than adults. Lead poisoning affects a child’s ability to think and judge, reaction speed, reading ability and attention, etc., making the child’s academic performance poor and the dropout rate increase. It is possible that the students with bad grades that teachers often complain about are the ones with lead in their brains. The children’s toys and pictures made of lead paint or lacquer are one of the main ways of lead exposure, which leads to lead poisoning in infants and children. Toys basically need to use spray paint, such as metal toys, painted blocks, injection-molded toys, balloons with patterns, books and picture books, etc. Even for plush toys, the eyes and lips of dolls or small animals are sprayed with paint, and most of the paint contains lead. Children holding toys to sleep, to kiss toys and to take things to eat without washing hands, are easy to cause lead poisoning. Many toys for children mainly come from the low-priced market, these toys are not safe. Parents to buy toys for children should go to the formal, reputable shopping malls, manufacturers of products into the mall need to be complete 8 certificates, including product safety testing certificate. Toys are sprayed with paint must be non-toxic paint, that is, lead content in paint and other national safety standards. Parents buy toys also pay attention to the warning language, see the toys indicate the appropriate age of the child.
