使用顶空/气相色谱-质谱法对儿童读物、小学课本、报纸中的16种溶剂残留进行检测。结果表明,检验的150批次样品中,有120批次检出溶剂残留;相比小学课本和报纸,儿童读物中各种溶剂检出率高,且有3批次儿童读物检出甲苯。儿童读物、小学课本、报纸均存在安全隐患,印刷厂家应采用绿色印刷以减少印刷品中的有害物质。
16 solvent residues in children’s books, primary school textbooks, and newspapers were detected using headspace / gas chromatography-mass spectrometry. The results showed that of the 150 batches tested, 120 batches of solvent residues were detected. Compared with primary school textbooks and newspapers, the detection rate of various solvents in children’s books was high, and toluene was detected in 3 batches of children’s books. Children’s books, primary school textbooks, newspapers are a safety hazard, printing manufacturers should adopt green printing to reduce the harmful substances in printed matter.
