Five Double Hole Shoes Were Found To Contain A Carcinogen.

reverent shoes We are all familiar with it because it is fashionable, light and comfortable, and is well received by consumers.

Recently, a survey released by German radio West Germany showed that many plastics " Crocs "A large number of carcinogenic polycyclic aromatic hydrocarbons (PHAS), which can enter the body through skin, may be harmful to health.

Now, many people are wearing hole shoes, many of them children. Can these shoes make people feel relieved? This people's livelihood laboratory bought 5 pairs of cave shoes from shopping malls, supermarkets and roadside shops, and commissioned the Zhejiang inspection and Quarantine Science and Technology Research Institute to conduct PHAS testing. As a result, 1 of the 5 pairs contain carcinogens.

Experimental sampling: there are many kinds of hole shoes in the market, there are recognized big brands, and there are "three no products", each price ranging from four hundred or five hundred yuan to more than ten yuan. The texture is light to heavy. The reporter randomly selected shoes of all prices and colors, a total of 5 pairs.

Experimental process:

1, sampling: cut out a few pieces of shoes touching the skin (vamp and insole) and cut them with scissors. The maximum particles are not more than 2~3 mm.

2, extraction: each sample is called 0.5g sample, mixed with toluene solution, then placed in an ultrasonic bath, and then extracted for 1 hours at constant temperature of 60 degrees Celsius. The inspector said that the process is similar to decocting Chinese medicine and extracting the components from the solid.

3. Determination: take an extraction solution and put it into special instrument (gas chromatography-mass spectrometry) to conduct qualitative and quantitative analysis of PHAS. The test covers 18 common PHAS and gets the sum of them.

Detection methods: reference to the German Safety Technology Certification Center (ZLS) for the detection of plastic products. In the method, the two category refers to components that are regular and skin contact, and the contact time will exceed 30 seconds.

At present, the detection of plastic shoes in China is based on this method.

PHAS release slowly, buy a smell before.

Before the experiment, the reporter asked several readers about the quality of the 5 pair of hole shoes. Their first feeling is that the cheapest shoes have a higher probability of having problems; those shoes bought in the shopping malls are guaranteed without fear.

The results of the test are somewhat unexpected. 5 pairs of shoes, ten yuan a pair, in the roadside shop to buy shoes is relatively safe. On the contrary, a pair of hole shoes purchased in regular shopping malls are "caught": PHAS content is seriously beyond the limit. This pair of shoes has a standard label, and the inspection grade clearly reads "qualified products".

　　 PHAS exceeding standard What harm is it? For ordinary consumers, how to choose safe and secure cave shoes properly?

Ruan Yi, director of the laboratory of light industrial products, which is responsible for testing of Zhejiang Institute of inspection and quarantine, said that PHAS has a certain carcinogenic risk, which is chronic poisoning and can be penetrated through skin. Especially in summer, sweat on the feet will promote the absorption and absorption of harmful substances. There is no authoritative data about how much time it will wear, and this is a cumulative process.

Judging from the test results, the PHAS content is not much related to the color of the shoes, but is related to the raw material control of the manufacturer. Consumers first smell the products when buying them, and there is a distinct tar smell. Please do not buy them. The PHAS content of these shoes will be quite high.

Skin sensitive people buy carefully.

Hangzhou City three hospital dermatin Colin told reporters that the production of cancer may be related to the addition of chemical substances, but the possibility of skin cancer through skin infiltration is unlikely.

It is worth noting that some of the patients themselves are allergic to gelatinized substances. If they wear inferior plastic hole shoes, their skin will not recover again and again. He suggested that when wearing "hole shoes" or other plastic shoes, it is best to wear socks to reduce direct contact between harmful substances and skin.

Summer is also a season of high beriberi. Some poor quality cave shoes are airtight and sweat is hard to volatilize. Long wearing may lead to dermatitis and allergies.
