Analysis of Migratory Elements in Toy Samples Using ICP Spectroscopy

摘要

Anumber of high-profile cases concerning t o y s contaminated with heavy metals, such as cadmium, lead, and arsenic, have highlighted the importance of rigorous testing of toy product samples for toxic trace elements. Many of these elements pose substantial health risks if ingested by children, including damage to the central nervous system and even death. Product samples of all toys must be routinely analyzed for heavy metals in order to preserve public safety. However, a recent study from the Ecology Center's Environmental Health Project and the Washington Toxics Coalition' tested 1200 toy products and found that more than a third of all toys tested contained toxic elements, the most common being lead, mercury, cadmium, and arsenic. Of the objects tested, 17% contained more lead than is allowed by federal safety standards (600 ppm). Some products had lead levels more than five times the allowed maximum. Cadmium levels greater than 100 ppm were found in 2.9% of products, and arsenic levels greater than 100 ppm were found in 2.2%.
