Wang Guangqian, an academician of the Chinese Academy of Sciences, once made a survey on Wuliangsuhai, and concluded that the situation of environmental pollution and ecological function degradation in Wuliangsuhai is serious. How serious is the water pollution in Wuliangsuhai? From 2005 to 2010, the chemical oxygen consumption reached the standard only three times, and the rate of nitrogen and oxygen exceeding the standard was 30.3%. The sediment pollution was serious, and the heavy metals exceeded the standard. The sediment pollution in West and East Datans was the most serious.
In fact, in recent years, pollution problems related to UL have been reported repeatedly, but the local people said that they did not feel any reduction in the pollution of the pharmaceutical factory. According to the reporter, at present, UL is constantly expanding its production scale. At present, Phase IV and Phase V projects are under way.
It is urgent to save Wuliangsuhai! Once Wuliangsuhai, with such an important ecological status, disappears, "land desertification will become more serious, deserts will drive straight in, and the sandstorm disaster in northern areas will be aggravated." The investigation report of the Human Resources, Environmental Protection Committee of the CPPCC National Committee said. It is not difficult to answer the difference between Wu Liangsuhai and some large profit and tax households.
