中国自20世纪90年代初以来，中国一直在接受来自国外的大量废弃电视、电脑、打印机和其他设备。科学家们在一次研讨会上认为，电子垃圾处理是中国沿海地区一个新兴的木屋行业，最终可能会让其他污染案例相形见绌。电子垃圾处理过程中释放出的物质是一场毒理学噩梦：它们包括已知的致癌物质，如二恶英和多环芳烃；神经毒性元素，如铅；以及溴化阻燃剂，包括多溴联苯醚，已被证明会扰乱实验室动物和野生动物的内分泌激素。自2000年以来，中央政府禁止进口电子垃圾，去年通过的一项法律要求电子垃圾处理者向地方政府注册，并采取措施控制污染。
ChinaChina has been accepting vast quantities of discarded televisions, computers, printers, and other equipment from abroad since the early 1990s. E-waste processing, a burgeoning cabin industry in coastal parts of China, may end up dwarfing other examples of contamination, scientists argued at a symposium. The roster of substances liberated during e-waste processing is a toxicological nightmare: They include known carcinogens like dioxins and polycyclic aromatic hydrocarbons; neurotoxic elements like lead; and brominated fire retardants, including polybrominated diphenyl ethers, which have been shown to disrupt endocrine hormones in lab animals and wildlife. Since 2000, the central government has prohibited importation of e-waste, and a law passed last year requires e-waste processors to register with local governments and take steps to control pollution.
