Soluble lead and cadmium in 24 kinds of children's toys were determined by atomic absorption spectrophotometer. The results showed that the concentration of soluble lead and cadmium in the toys which had a paint coating were respectively from 110.3 mg/kg to 5,156.0 mg/kg and from 0.34 mg/kg to 35.50 mg/kg, but soluble lead and cadmium concentration in the toys which did not have a paint coating were very low. This study suggested that the children's exposure to lead and cadmium was mainly from the paint coating of toys, and that the important problem was too high concentration soluble lead in the colouring and varnishing substances. In preventing children's exposure to low lead and cadmium level, the hazards from toys containing soluble lead should be paid attention.
采用原子吸收分光光度计测定了24种儿童玩具中的可溶性铅和镉。结果表明，有油漆涂层的玩具中可溶性铅的浓度为110.3毫克/千克至5156.0毫克/千克，可溶性镉的浓度为0.34毫克/千克至35.50毫克/千克，而无油漆涂层的玩具中可溶性铅和镉的浓度非常低。本研究表明，儿童对铅和镉的接触主要来自玩具的油漆涂层，且重要问题是着色和清漆物质中可溶性铅浓度过高。在预防儿童接触低水平铅和镉时，应注意含可溶性铅玩具带来的危害。
