- Department:Toxic and Chemical Substances Bureau

Idea and core spirit
The idea of the logo of the Toxic and Chemical Substances Bureau came from the Chinese character "化" (or "chemical"). The atomic chemical bonds and house shape in the blue circle and green sphere imply that the visual conception of the Toxic and Chemical Substances Bureau is rooted in the blue sky and green land, and conveys the core value of having a home free from toxins.
Color and organizational mission
The softened blue and green are derived from the logo of the Environmental Protection Administration. The modern, professional and vibrant principles of coloring demonstrate the organization's tasks and missions in constructing a sustainable, friendly and green chemical environment.
