摘要
A large quantity of industrial hazardous wastes (IHWs) accumulates in the Three Gorges Region. This study found that approximately 15 000 t IHWs were piled in the region by October 2001. These IHWs came from various sources and were complex in composition, mostly toxic and difficult to be disposed. IHW is regarded as a potential threat to the ecological environment, water resources and survival of local residents. It is important and indispensable to dispose the waste properly. To meet the regulation requirements on the disposal of IHWs and to minimize environmental effects on the Three Gorges Region, a disposal strategy is proposed, according to which approximately 600 t of the IHWs can be disposed by chemical stabilization, incineration and other treatment measures, and the rest need be stockpiled in safe and reliable places situated above the 177 m impoundment line of the Three Gorges dam.
