Former businessman now a crusader for safe kids’ products
Since discovering harmful chemicals on the school books used by his daughter, Wei Wenfeng has been advising parents about similar issues

Hangzhou-based businessman Wei Wenfeng embarked on a career change well into his professional life. Wei, 40, became concerned that the covers on school books on the market used by his only daughter contained harmful chemicals. Now he runs a firm that advises parents on the safety of everyday products. He spoke to Maggie Zhang.
How did this venture get started?
Last year, I sometimes discovered a strange smell coming from the plastic covers of books used by my nine-year-old daughter who is at primary school. As a veteran inspection engineer, I suspected these covers might contain harmful chemicals. So I paid more than 1,000 yuan (HK$1,120) to test a cover at the China National Supervision & Testing Centre of Fine Chemicals in Taizhou, Jiangsu province.
The test report proved that the product contained hazardous amounts of two materials, phthalate and polycyclic aromatic hydrocarbons, or PAHs. The first can harm children’s later reproductive health while the latter can cause cancer.
