Heavy metal leaching of electronic waste has been documented in recent literature. Heavy metal aquatic toxicity in the toxicity characteristic (TC) leachates produced from 56 electronic devices were tested using the aquatic toxicity assays such as Ceriodaphnia dubia 48-hr acute toxicity assay, the Selenatastrum capricornutum chronic algal growth inhibition assay (test used only for circuit-board leachates), and the MetPLATE acute heavy metal toxicity tests. The electronic devices tested, include 9 circuit boards (printed wire boards), 2 videocassette recorders, 4 remote controls, 1 cathode ray tube, 15 cellular phones, 1 calculator, 5 smoke detectors and their PC board components, 3 printers, 4 laptop computers, and 7 personal computer central processing units (CPUs). The toxicity tests showed toxicity in 51 of the 56 Toxicity Characteristic Leaching Procedure leachates of electronic devices assayed.
近期文献中已记载了电子垃圾的重金属浸出情况。使用诸如大型蚤48小时急性毒性试验、羊角月牙藻慢性藻类生长抑制试验（该试验仅用于电路板浸出液）以及MetPLATE急性重金属毒性试验等水生毒性测定方法，对56种电子设备产生的毒性特性（TC）浸出液中的重金属水生毒性进行了测试。所测试的电子设备包括9块电路板（印刷线路板）、2台录像机、4个遥控器、1个阴极射线管、15部手机、1个计算器、5个烟雾探测器及其印刷电路板组件、3台打印机、4台笔记本电脑以及7个个人计算机中央处理器（CPU）。毒性测试表明，在所分析的56种电子设备的毒性特性浸出程序浸出液中，有51种具有毒性。
