Drawing chopsticks is beautiful and cheap, but from a health point of view, it is not good for your health. This is because paint is a polymer organic compound, most of which contains toxic chemical components, especially yellow paint, which is made of yellow pigments containing lead and chromium. The lead content accounts for 64% of the total pigment, and the chromium content also reaches 16. 1%. Some green (mixed with blue and yellow) and brown (mixed with yellow, red and black) paints also contain lead and chromium. Long-term use of painted chopsticks to eat, especially when paint falls off and is swallowed with food, lead, chromium and other toxic substances enter the human body and accumulate, which is in danger of chronic poisoning. The dose of lead poisoning is 0. 04g, the lethal dose is about 20g. Lead entering the body every day exceeds 1 mg, which will cause harm to human body. Lead mainly damages the nervous system, hematopoietic organs and kidneys. In severe cases, it can cause metallic taste in the mouth, gingival lead, gastrointestinal symptoms, neurasthenia and muscle pain. In particular, it will affect children's intellectual development. Therefore, it is best not to eat with painted chopsticks in daily life.
