Hazardous waste pollution preparedness system based on the 3S technology

The present paper aims to introducing the authors' work on preparing a Hazardous Waste Pollution Preparedness System based on the 3S Technology,that is,the Remote-Sensing(RS),the Geographical Information System(GIS) and the Global Positioning System(GPS).The so-called Hazardous Waste Pollution Preparedness System has been taken to form a four-level comprehensive hazardous waste pollution preparedness system including those of the state,provincial,municipal as well as the county.The state-level is assigned to be in charge of the province-boundary hazardous waste pollution emergencies and guides the provincial level hazardous waste pollution preparedness system,while the provincial level system is in charge of the intercity-boundary waste pollution businesses and gives instructions to the city-level system.The city-level is responsible for the county-boundary hazardous waste pollution incidents and emergencies and gives instructions to the work of the county-level system.And,in turn,the county-level is to manage things with the inter-county hazardous waste pollution preparedness system.Therefore a hazardous waste preparedness system all over the country will be made to work efficiently,which will enable the entire in-site environmental monitoring system to work steadily and fast in quickly disposing,integratedly leading and forecasting the likely pollution emergencies to occur by applying the 3S technology.Furthermore,the paper has also discussed the supporting conditions of the technology and the economic feasibility of the method.A case study in Liaohe River,Liaoning,has also been introduced to demonstrate how the system has actually been working based on 3S technology.
