[Establishment of VOCs Emissions Factor and Emissions Inventory from Using of Architectural Coatings in China].

Volatile organic compounds (VOCs)are important air pollutants in China, and control of their emission is an important subject of air pollution prevention and control.Architectural coatings play a significant role as sources of atmospheric VOCs in China.Due to recent economic development and increase in the levels of urbanization, the building of residences and other buildings is ongoing all the time, which results in increasing demand for architectural coatings and the VOCs pollution caused by painting operations.

[Content Levels and Compositions Characteristics of Volatile Organic Compounds(VOCs) Emission from Architectural Coatings Based on Actual Measurement].

The content levels and composition characteristics of Volatile Organic Compounds (VOCs) from architectural coatings including interior wall coatings, exterior wall coatings, waterproofing coatings, anticorrosive coatings and floor coatings were investigated in this study. Architectural coating samples were obtained from manufacturers and retail outlets and the associated VOC contents and compositions were determined based on the domestic standard methods for measurement of VOCs in architectural coatings.The results showed that the VOC contents were 0-145 g·L and 0-171 g·L for interior and exterior wall coatings respectively.
