A Study On Pollution Risk Assessment And Emergency Strategy On Petroleum And Chemical Docks And Ships In Circumjacent Sea Area Of DaGu Mountain In Dalian

DaGu mountain Economic Development Zone is located between dalian bay and dayao bay. According to dalian's city development plan, DaGu byland breaks traditional preponderant aquaculture and is affirmed to be petroleum and chemical area. Along with Fujia PX and Yisheng PTA project launch at petroleum and chemical industrial area of southern of DaGu mountain, the new vision that petroleum import is center in NianYu Bay and two wings on petroleum and chemical dock is formed in DaGu mountain water area.Load and unload of petroleum and chemical raw material and product is easily to cause hidden danger. Once the leak of petroleum and chemical product and the accident of fire and explosion happened on ships, these will result in serious damage on aquicolous zoology, pollution on the quality of sea and land environment.
