上世纪六七十年代,日本经济快速增长,污染事件不断。中国正在经历和日本上个世纪同样迅速的经济增长,污染也在同步增长。新世纪以来,和重金属有关的环境事件愈见频繁。继去年陕西凤翔血铅事件之后,今年又相继发生了四川内江、湖南郴州等地群众血铅超标及中毒引发的群体性事件,土地污染问题日益突出。而对于土壤直接产生危害的重要来源,就是“农用肥料”。根据2010年初国家污染源普查结果,我国主要污染物排放量有四成以上来自农业污染源。农业大规模施用化肥、不科学施用化肥及化肥本身的环保性能不佳是导致污染的重要原因。
In the 1960s and 1970s, Japan’s economy grew rapidly and pollution incidents continued. China is experiencing the same rapid economic growth as Japan’s in the past century. Pollution is also growing at the same pace. Since the new century, heavy metal-related environmental incidents have become more frequent. Following the blood lead incident in Fengxiang, Shaanxi last year, this year there have been mass incidents of excessive blood lead and poisoning in the Neijiang, Sichuan, and Chenzhou areas of Hunan Province. Land pollution problems have become increasingly prominent. The direct source of harm to the soil is an important source, is “agricultural fertilizer ”. According to the results of the national pollution census in early 2010, more than 40% of China’s major pollutant emissions come from agricultural sources. Large-scale application of fertilizers in agriculture, unscientific application of chemical fertilizers and poor environmental performance of their own pollution is an important cause of pollution.
