測試也發現在4大受歡迎的背包中，其含鉛量都在3,700ppm以上，甚至高於9,100ppm，包括了湯瑪士小火車背包（Thomas and Friends backpack）、愛探險朵拉後背包（Dora the Explorer）、迪亞哥包（Go Diego Go）和Hello Kitty巧克力貓包等。
High levels of lead in children's backpacks, rain ponchos, vinyl lunchboxes and toys are documented by nonprofit environmental health and consumer protection groups in two reports this week. In addition, the federal Consumer Product Safety Commission announced recalls of children's jewelry and school supplies with illegal levels of lead. The findings serve as warnings to shoppers with children on their lists this holiday season.
The Center for Environmental Health, based in Oakland, California, together with the grassroots online group MomsRising.org commissioned lab tests of children's products for lead. Many tested way above the legal limit for lead in paint - 600 parts per million. The federal limit applies although public health experts now say there is no safe level of exposure to lead.
The testing found lead levels ranging from 3,700 ppm to more than 9,100 ppm in four backpacks - Thomas and Friends backpack, Dora the Explorer, Go Diego Go, and Hello Kitty's "Chococat."
Children under the age of six are especially vulnerable to lead's harmful health effects, because their brains and central nervous systems are still being formed.
For them, even very low levels of exposure can result in reduced IQ, learning disabilities, attention deficit disorders, behavioral problems, stunted growth, impaired hearing, and kidney damage. At high levels of exposure, a child may become mentally retarded, fall into a coma or die from lead poisoning.
