Report Abstract: A Material and Toxic Plasticizer Survey of 86 Kinds of Eraser Product in the Market

In March 2020, in order to reduce the impact of toxic plasticizer exposure on students' health, Toxics-Free Corps launched a systematic product safety market survey for eraser, an important category of stationery. The eraser samples collected in the survey come from the three E-commerce platforms including Taobao, Jingdong and Pinduoduo, as well as the on-site purchase of offline stores, with a total of 86 items, involving 33 well-known stationery brands. The investigators first used XRF analyzer to analyze the materials of all 86 kinds of eraser samples, and then sent 62 of them to a qualified third-party laboratory to test the content of 6 kinds of phthalic acid esters (PAEs).
