1.必须采取紧急行动对付水质污染据公开发表的数据,1986年流淌在地表水域的污水量是超过允许范围的150亿 m~3,与1985年相比减少了8亿 m~3。但这些数据所具有的意义是有限的,因为其中对有关污染的程度未提供任何线索,而且是否包括所有的污染水还有疑问。现存的处理设备大致1/3没有达到废水净化标准。从国内几乎所有的地区汇集来的报告都显示了水质保护不完善,顿河、鄂毕河、额尔齐斯河、卡马河的水质已恶化到了相
1. Urgent Action to Address Water Pollution According to publicly available data, the amount of sewage flowing into surface waters in 1986 was over 15 billion m 3 exceeding the allowable range, a decrease of 800 million m 3 compared with 1985. However, the significance of these data is limited because it does not provide any clues as to the extent of the pollution involved, and it is questionable whether all contaminated water is included. Approximately one-third of the existing treatment facilities do not meet the wastewater purification standards. The report compiled from almost all parts of China shows that the water quality protection is not perfect and the water quality of the Don River, Ob River, Irtysh River and Kama River has deteriorated to the phase
