Scope

Main Technical Content: 5. Construction of Emission Scenarios for the Coatings Industry The construction of environmental emission scenarios for chemical substances in the coatings industry largely depends on the availability of effective information. Typically, the construction process includes four steps: determining the scope of the emission scenario, collecting scenario information, establishing the emission scenario, and compiling an emission scenario document. The schematic of the emission scenario construction process is shown in Figure 1. **Figure 1: Schematic of the Emission Scenario Construction Process** 6. Content of Emission Scenarios 6.1 Environmental Emission Scenarios for Chemical Substances in the Coatings Industry Should cover all information necessary for environmental emission estimation and reflect the standardization and normalization of relevant information. The construction of the emission scenario should organize relevant information rationally and clearly demonstrate the relationships between the emission sources, emission pathways, and environmental media of the coatings chemical substances to be evaluated. 6.2 Before Constructing the Emission Scenario, Ensure the Accuracy and Representativeness of the Collected Scenario Information and Evaluate It Using Methods Such as Evidence Weighting, Where Necessary. Typically, the collected scenario information should at least represent either the worst-case emission scenario or a typical emission scenario. All collected scenario information should not be disorganized and should be relatively unified, organized, standardized, and structured. When the information fails to meet the requirements of environmental risk assessment, additional collection of scenario information is necessary. 6.3 Content of the Emission Scenario 6.3.1 To Construct Environmental Emission Scenarios for Chemical Substances in the Coatings Industry, the Following Six Aspects Should Be Clearly Reflected:
