Diesel oil of Shaanxi leaks pollution Wei river and the Yellow River
It is reported ' Reporter Zhang Hao) A few days ago, the incident of leakage of diesel oil happened in Shaanxi Province, river of Wei and the Yellow River, some section water quality, was polluted by the petroleum material. The environmental expert pointed out yesterday, water pollution would threaten some drinking water along city on the bank safely when being interviewed by reporter. It is reported, before dawn on December 30 of 2009, the leakage of diesel oil takes place in the course of trying out in the south branch line of Wei of long readymade oil pipeline of CNPC blue Zheng located in Shaanxi Province Wei Nanshi, it is about 150 tons to let out the total amount. The oil spill flows into river of Wei subsequently, and flow into the upper reaches of the Yellow River (the domestic segment of Sanmenxia of Henan Province) partly . Both regard water of the Yellow River as the drinking water and source of water in big cities such as Zhengzhou, Kaifeng of the low reaches of the Yellow River,etc., the Yellow River pollutes and threatens the security of drinking water of these cities. Monitor the result newly according to environmental protection department, at present, the petroleum material density in Sanmenxia reservoir has already been returned to water getting level in the earth's surface, this means petroleum material content in Sanmenxia reservoir for 0.5 milligrams / rises to 1.0 milligrams / liter, still in higher level. The environmental expert explains, the diesel oil is polluted and mainly influenced by ecology. Floating in the above-water oils can be spread rapidly, form the oil film, hinder the surface of water from keeping in touch with the air, dissolve oxygen to reduce in water, it is smelly to cause the water body. Though the intersection of diesel oil and pollutant toxic material, the intersection of drinking water and standard CNPC relatively loosely requirement of total amount, but the content of the CNPC material in Sanmenxia reservoir is still higher than " drinking water sanitary standard " (GB5749-2006) The ones that stipulate " Drinking water CNPC ( Total amount) Should be lower than 0.3 milligrams / liter " Standard. If this pollution can't be got and controlled effectively in time, will threaten the security of drinking water of the downstream city seriously.
