When children are just learning to eat, or when children don’t like to eat, many parents will choose to buy beautiful color tableware for children, hoping to guide children to eat with tableware. However, some cutlery with lovely appearance and beautiful color have huge hidden danger!
Uncovering the colorful tableware
Recently, a two-year-old child died suddenly in Vancouver, Canada. After medical examination, it was found that the root cause was: the child drank the apple juice in the colored porcelain pot for 29 consecutive days, resulting in lead poisoning.
Dong Jinshi, Secretary General of Beijing environmental protection tableware joint organization, said that in daily life, some colorful ceramic tableware and crystal vessels are one of the sources of lead pollution. There are a lot of lead, antimony and other metal compounds in the raw materials (clay) and colored glaze of ceramic products. If such vessels are used to hold acid food or drink such as wine, fruit juice, vinegar, etc., the lead in colored glaze will dissolve in food or drink. Not long ago, AQSIQ released the results of random inspection on the quality of domestic ceramic catering utensils, with a qualified rate of only 54.5%. Most of the unqualified products come from collective, individual and private small enterprises, in which the content of lead and cadmium is too high. However, the amount of lead dissolution mainly comes from ceramic pigment decals. For example, if the area of decorative materials is too large, the temperature of baking flowers is not enough or the processing is not proper, the amount of lead dissolution will exceed the standard. As for the porcelain products “imported from abroad”, we can’t take it lightly blindly. Not long ago, the customs of Hong Kong inspected 600 kinds of porcelain tableware from Japan, Italy, Britain, Portugal and other countries, including bowls, plates, cups and spoons of different sizes. As a result, 526 kinds of porcelain tableware did not conform to the international standards, releasing excessive heavy metal lead, and the unqualified rate was as high as 88%.
Crystal products with gorgeous appearance often contain 20% – 30% lead oxide. Some people have carried out experiments, using crystal containers to hold wine, an hour later, the lead content in the wine doubled. If a liter of brandy is put into a crystal vessel, 5 years later, the lead content in the brandy can be as high as 20000 micrograms, far exceeding the regulations of the environmental protection department that the lead content in the drink should be less than 50 micrograms / liter.
Paint chopsticks are also the traditional food utensils in China. They are noble, elegant and highly decorative. But because paint is a polymer organic compound, most of them contain toxic chemical components. For example, the lead content of yellow paint accounts for 64% of the total pigment, and the chromium content is also 16.1%. Long term use of paint chopsticks for meals, especially when the paint falls off and goes into the stomach with the food, lead and chromium and other toxic substances enter the human body and are accumulated, there is a risk of chronic poisoning. Therefore, it is better not to paint chopsticks in daily meals, but to use non-toxic and hygienic bamboo chopsticks or wooden chopsticks; in addition, chopsticks should be frequently disinfected and replaced every half a year to avoid chopsticks becoming the vector of disease.
Plastic is everywhere in people’s life, plastic tableware is an important part of household appliances. At present, the safer plastic meals include polyethylene, polystyrene, polypropylene plastic products, etc. Wan Qing, director of scientific research office and senior engineer of light industrial plastics processing and Application Research Institute, said that due to the high price of raw materials for melamine tableware, some illegal enterprises, in order to pursue profits, replaced urea aldehyde molding powder in the production of melamine tableware, and then coated a layer of cyanuric chloride powder on the surface of tableware, while the tableware made of urea aldehyde is harmful to human body; some enterprises It is no doubt that these products are harmful to human body to reduce the cost and use the waste plastic smuggled from abroad or recycled in China to make plastic tableware. Because these products can not have the pure color of qualified products, they are often processed into some bright colors. China Consumer Association has published the comparative test results of 317 brands of plastic baby bottles. It is found that the release of heavy metals on the surface of several brands is surprising. The release of lead is 2-20 times higher than the European safety standard, and the chromium content is 1-5 times higher.
The harm of aluminum tableware to human body is almost known to all. Not long ago, the “TEFLON” event of various coal bodies, which makes people need to be vigilant, added a non stick pot to the unsafe tableware. If the ordinary iron pot wanted not to stick to the bottom, it would be coated with a layer of plastic called “polytetrafluoroethylene” on the inner surface of the pot. If the product comes from a small workshop with incomplete facilities, it is possible to mix fluorine monomers in this layer of “plastic” and release them when heated, which is harmful and unhelpful. The non stick pot sold in the supermarket is not likely to be a “poison pot”. But “polytetrafluoroethylene” will decompose if it is heated to more than 400 ℃, and the released “tetrafluoroethylene” is a highly toxic gas. This kind of plastic can be applied to the inner walls of non stick pots and electric rice cookers, so be careful not to burn the pots over the fire.
Therefore, we say that some tableware, good-looking is not necessarily safe, parents or to buy safe and practical healthy tableware for the good! If you want to know more about how to disinfect children’s tableware, you can go to Baibai safety net to search!
