The cars torn into two sections by the explosion and the road that has become a river seem to be accusing of this disaster. Like the 2010 Dalian oil pipeline explosion, the harmful gas produced by this accident will cause unpredictable harm to the local ecology< According to the Publicity Department of the working committee of Qingdao Economic and Technological Development Zone (Huangdao District), about 18000 people have been evacuated from 12 communities in Huangdao District.

Another point is the intersection of Huaihe Road and Penghu 1sland street, which measured the concentration as 1mg / m3, and the standard is 4mg / m3. 1t can be seen that the monitoring data is still in the safe range the Qingdao Municipal Environmental Protection Bureau recently released the preliminary report on environmental emergencies caused by oil pipeline leakage in Qingdao Development Zone on its official microblog, saying that the monitoring shows that the concentration of non methane hydrocarbons in the downwind direction has not exceeded the standard. 1t is understood that non methane hydrocarbons usually refer to all volatile hydrocarbons except methane. When the concentration of non methane hydrocarbons in the atmosphere exceeds a certain level, it is harmful to human health directly.
