More than a dozen U.S. environmental health organizations claimed that many children's toys, jewelry and backpacks were found to contain excessive amounts of lead after testing. This investigation began a while ago when lead-containing toys were recalled due to safety issues, and the investigation targeted more than 1,200 products from chain stores and self-operated stores. The investigation found that among the 1,200 products tested, 17%'s product exceeded the lead content stipulated by the federal government. Tracey Easthope, director of the environmental health program at the Environmental Research Center in Ann Arbor, Michigan, said, "The findings do not indicate that these products pose an immediate danger to consumers, but they do show that the government is not They fail to perform their supervisory duties to detect products containing toxic chemicals, and too many manufacturers do not self-regulate the products they produce.” Among the products tested, children’s toys and jewelry accounted for one-third of the total. one. The main test item for these children's toy jewelry is whether it contains lead. Because young children are particularly vulnerable to exposure to lead-containing products. The other two-thirds of the products tested were tested for lead, as well as eight other potentially hazardous chemicals such as antimony, arsenic, bromine, cadmium, chlorine, chromium, mercury, and tin. The test results revealed that the tested products also contained very high levels of cadmium and arsenic. However, it should be noted that this survey did not further evaluate the direct impact of the tested products containing chemical substances on human health.
