In recent years, children and young people as a fashionable light stick stuff and some media have also said: "light sticks ingredients-n-methyl ester and dibutyl phthalate, and has low toxicity. If you accidentally spill, aspiration or touched by the body, can cause nausea, dizziness, numbness and even harmful to human health such as coma. "Department of chemistry, Tsinghua University, Institute of physical chemistry of Zhao fuqun said, if properly used, light stick will not cause too much harm to the human body.
As the GLO-sticks and liquid chemicals are in polyethylene (plastic) packaging, so it will not cause too much harm to the human body. Because GLO-sticks and the light emitted by a chemical reaction inspired the non-radioactive light dye, rather than radiation excited dyes emit light, will not harm the human body. But Zhao fuqun today some people to keep up with fashion, and sticks broken, liquid inside covered himself opposes, because chemicals in the light sticks in direct contact with the skin can cause some damage to the human body. Especially careful not to let children eat.
View fluorescent substance will damage the body, because in some luminous watches, mines use of emergency lights and other radioactive material, dye-glow in the dark, people mistaken for light sticks are also used in radioactive material, form a cognitive error. Consumers identify a radioactive glow of luminous products through the radioactive glow of long duration and low light level and non-radiation light of shorter duration.
