Improper use of plastic net products can cause cancer

Mr. Wang is a planner for an advertising company in Zhengzhou, and stays up late because of work.

At 11pm on December 20th, Mr. Wang felt a little hungry. He opened a bag of instant noodles, added hot water and eggs, and put the instant noodles into the microwave oven. After 5 minutes, a bowl of microwave noodles was hot and baked. Mr. Wang, holding his job, opened the computer.

At this time, a netizen sent a message, Mr. Wang opened the link, after reading the surface of his bowl can not eat anymore. This is a post titled "From the bottom of the plastic bottle to see its toxicity, ignorance will kill people", this post explains the meaning of the plastic bottle bottom number, describes in detail the use of plastic products No. 1 to 7, where Mentioned in bowl-shaped instant noodles, fast food boxes should be marked in the triangle symbol "6", such plastic products belong to the heat and cold resistant plastic products, but can not be put into the microwave oven, so as to avoid release of chemicals due to high temperature, And can not be used to dress strong acid (such as orange juice), strong alkaline substances, because it will break down the harmful to the human body polystyrene, easy to cause cancer.

What makes Mr. Wang even more frightened is that at the end of the text, a girl from the United Arab Emirates said she had cancer because she used the same plastic water bottle for 16 consecutive months.

Mr. Wang said that many of the “improper practices” in the article have been done by themselves, such as using mineral water bottles to store water several times and heating the food with a snack box or plastic wrap in a microwave oven.

In response to Mr. Wang’s doubts, the reporter conducted an investigation of drinking cups, water bottles, baby bottles, and disposable cups frequently used by consumers.

At Renmin Road Dennis Supermarket, the reporter viewed nearly 20 kinds of drinking glasses. Most plastic products have no triangular marks on the bottom, and only two models have triangle marks on the bottom of the drinking glass. A thermal space cup is printed with a "5", and another button-type cup is printed with a "7" at the bottom. According to the content of the post, "5" represents that the material can be placed in a microwave oven, and "7" represents that the plastic material can be used for a kettle, a cup, and a baby bottle.

Afterwards, the reporter asked a staff member in the store. What does the triangle symbol mean? Why are some water cups marked and some are not marked?

"Not too clear." The staff member said. At the bottle counter on the second floor of the Renmin Road Dennis supermarket, the reporter found that many plastic bottles were not marked with triangles. Later, the reporter conducted investigations on the “triangular” signs of 30 consumers at supermarkets such as Yichu Lotus and Beijing Hualian. The answer for all consumers is uniform and "do not know."

Plastic Association logo has nothing to do with the safety of plastic products

What does the "triangular" sign mean? How much influence does it have on our health?

In a telephone interview with the General Secretary of the China Plastics Association, Ma said that the digital signs in the bottom triangle of plastic products are equivalent to plastic ID cards. The triangle formed by three arrows means that the bottle's material is "recyclable". This kind of digital recycling mark is a standard type of plastic. Numbers are from 1 to 7. Each number represents a type of material. For example, a product with a number “1” will be recycled according to the category of “1”.

Secretary-General Ma said that this kind of sign was promoted by the state and each plastic product should be marked. At present, most of the standardized companies have annotated. However, because this standard is just promotion, it is not mandatory, so it is not labeled. There is no mandatory requirement for a specific labeling location, and no requirement must be placed on a prominent location. Without affecting the appearance of the product, just label it.

Regarding everyone's doubts about plastic safety, Secretary-General Ma said that the different numbers of logos are easy to classify and recycle, and have nothing to do with the safety of plastic products.
