In 2012, “ 3· 15” teaching materials for teaching materials and food packaging and printing quality supervision and inspection activities, the quality inspection center of the General Administration of the General Administration organized the environmental quality sampling test for the primary and secondary school textbooks for the implementation of green printing. The environmental quality (volatile organic compounds and transferable elements content) of 95 kinds of primary and secondary school textbooks for green printing were all in accordance with the requirements of technical standards, and the qualified rate was 100%.

The 95 green printing primary and secondary school textbooks were produced by lithography printing process. The seal was printed with “ China environmental label ” logo.

The determination methods, procedures, equipment and conditions of the headspace gas chromatography (YC/T207-2006) and the national toy safety technical specification (GB6675-2003) for the determination of the organic compounds of the organic compounds are tested for the content of the harmful substances in the samples. The content of 16 volatile organic compounds, such as benzene, toluene, ethylbenzene and xylene, and 8 kinds of transferable elements, such as chromium, cadmium, selenium and barium, are obtained by testing and determine whether they are in accordance with the standard requirements.

The test shows that the content of volatile organic compounds and transferable elements in 95 kinds of primary and secondary school textbooks for green printing meet the limit requirements, and the quality of environmental protection is 100%.
