There are reports that carcinogens are present in mobile phone cases, so are the mobile phone cases

A doctor from the Building Environment Monitoring Center of the Department of Building Technology and Science at Tsinghua University said that the formaldehyde may come from the adhesive used on the phone case, or it may be emitted unsteadily from the silicone shell material。Nowadays, some benzene homologues are used to replace benzene as organic solvents, and if these organic solvents are not of high purity, they may contain a certain amount of benzene.

It seems that the statement that phone cases release carcinogen benzene is true, but the amount released is not as horrific as the rumors say. Both silicone and leather phone cases emit formaldehyde above air quality standards. Although the use of such a product is not certain whether it will exceed the formaldehyde concentration in the air, it will increase the risk of inhaling more formaldehyde.

Since there is no national standard for mobile phone cases in China, we have to use the national standard for indoor air quality as a reference. The standard stipulates the benzene concentration limit, and the test results show that the benzene concentration range is between the range, and the amount of benzene released is not large.

Dr. from the Building Environment Monitoring Center of the Department of Building Technology and Science at Tsinghua University said that because our experiment heated the phone case tightly for an hour, the release was higher than that of daily use. Because benzene is more harmful to the human body, the state has taken regulatory measures to restrict the use of benzene.

Precautions: 1. Try to choose a mobile phone case without obvious odor.

2. Try to use the phone case in a ventilated environment.

3. Reduce children's contact with mobile phone cases.

Our phone cases should be safe, only a small amount of them are carcinogenic.

It only contains trace amounts of carcinogens, but it still does not affect the use, and there are still cancer cells in the human body.

Generally speaking, it is safe, and the plastic of the phone case is quality guaranteed.

No, if it really causes cancer, then people all over the world will get cancer.

If it is not such a carcinogen, it should be caused by some plastic shells.

I don't think there's much correctness to believe in this, and I need to improve my awareness of prevention.

In fact, the impact of mobile phones on people is completely greater than the disadvantages of mobile phone cases.

I think it should be like this, do you think it will be like this?

It only contains trace amounts of carcinogens, but it still does not affect the use.

The dangers of metal phone cases? Long-term use of mobile phones not only has radiation hazards to the human body, but also has a lot of harm to the body. What are the hazards of metal phone cases?

1. According to the principle of physics, a metal phone case will affect the signal received by the mobile phone, because metal things will block the radio waves.

The transmitter, so you use such a phone case, will have a great impact on your phone signal.

2. The metal is not wear-resistant, and it no longer has the luster of the new machine after a long time, and it is permanently rough, and the old metal shell is more ugly than the new plastic shell.

3. The metal shell is generally not made into a detachable back cover, which means that you usually can't replace the battery, and it is also very inconvenient to take the card needle.

4. The metal shell is not resistant to falling, one fall and one is missing, and the permanent cannot be recovered.

5. The metal shell is conductive, and once the contact is poor, personal danger electric shock may occur.

If your phone case is made of recycled rubber, it will contain a lot of aromatic oil, which is absolutely carcinogenic.

Phenol is recognized as a toxic chemical, once absorbed by the human body, it will accumulate in the tissues of various organs, it is difficult to excrete from the body, when the phenol reaches a certain amount, it will destroy liver cells and kidney cells, causing chronic poisoning, and the harm to children is particularly serious. The Ministry of Health promulgated the "Measures for the Hygiene Management of Plastic Products and Raw Materials for Food" clearly stipulating: "All plastic shall not be used in the processing of plastic utensils, containers, and food packaging materials."

The National Institutes of Health has published the results of a new study on bisphenol A. The report is based on 18 months of research and analysis of animal experiments from about 500 laboratories. Experts from the National Toxicology Programming Division, part of the hospital, have found that even small amounts of BPA can cause harm to animals — in experiments, mice exposed to BPA showed signs of breast cancer, prostate cancer and other cancers.

Plastics contain a lot of phthalates and bisphenol A, especially thin and soft low-quality plastic bags. Dr. Zhou Yiqi of the Chinese Academy of Sciences' Research Center for Eco-Environmental Sciences told China News Weekly that the combination of these compounds with PVC is very unstable, just like the sand in rice, which is very tolerant during contact.

It is volatile and adsorbed by the human body.

If it is said that it is very possible to prevent radiation from mobile phone cases, it is impossible to cause cancer, and there are also individual mobile phone cases with certain carcinogenic substances....

Could it be that the landlord ate the phone case?

Many young people like to put on a personalized "coat" for their mobile phones, but recently a news that "mobile phone cases contain super carcinogens" has gone viral on the Internet, and many citizens have worried about mobile phone cases for a while. Experts said that the products produced by regular manufacturers that meet national standards contain very few harmful substances and have little impact on the body.

Mobile phone mesh shells are a subspecies of soft shells, named after the mesh vents in the case, and the design is usually simpler. Many users prefer mobile phone mesh shells. There is no other reason, the structure is sturdy and the heat dissipation is fast, and the phone looks refreshing and concise at a glance.

[Expert statement: the benzene contained in the mobile phone case has little effect on the human body].

Process processing and raw materials may cause carcinogens, especially plastic additives and polymer intermediates when the reaction is incomplete, it will cause carcinogenesis, but the online upload is "a bit outrageous".

As an organic solvent, benzene behaves as a colorless liquid at room temperature and has a distinct aroma. However, products such as mobile phone cases do not contain pure benzene, but phenyl polymers, which are basically non-toxic and volatile when the product leaves the factory. Therefore, the use of such products in daily life has minimal impact on the body.

[How to choose a safe and non-toxic phone case].

1. First of all, you have to look at it, don't be too fancy, too bright, you have to be careful.

2. The second thing to smell is that there is a pungent smell, or it smells disgusting, or it chokes your eyes, don't choose it.

3. If you touch it with your hands, it is too soft and faded, or if you feel that there is a peculiar smell on your hands after touching, and the hardness and strength are particularly large, don't choose it.

The raw materials of the mobile phone case are hard plastics, aluminum alloys, and steels, and it is recommended to buy metal, which is nothing.

Really, it's just more than 20 yuan, and the effect is not very big, go to the store to buy.

Mobile phone cases are frequently used and touched by consumers every day, girls like to buy all kinds of mobile phone cases to dress up their mobile phones, and then many people do not know that many carcinogens in mobile phone cases are exceeded!

On April 12, the Shenzhen Institute of Quality Consumption tested 30 mobile phone cases and found that many mobile phone cases exceeded the limit of toxic and harmful substances. **The 288 yuan Apple phone case was found to be nearly 50 times more carcinogens than the standard, and the lead content of the "rhinestone glitter pastel film" protective case that girls loved exceeded the standard limit by 1550 times.

The report shows that 5 mobile phone cases were detected with toxic and harmful substances, and the content of toxic and harmful substances detected exceeded the requirements of the standard limit, namely: Apple, Xiaomi, Tia, Qguo, and Yuening. Among them, the content of polycyclic aromatic hydrocarbons (internationally recognized strong carcinogens) in the Apple mobile phone case is 94MK kg, which exceeds the standard single limit by nearly 50 times; The plasticizer content of the Xiaomi phone case is exceeded, exceeding the limit value (requirements; The girls' favorite Yuening "Rhinestone Glitter Pastel Film" protective case has a lead content of 155,000 ppm, which is 1,550 times higher than the standard limit.

It is hoped that the state will introduce standards. Think about the phone case every day and be scared!

Yes. But only in very small amounts.

The purchased mobile phone cases contain benzene and formaldehyde to varying degrees. Some low-quality mobile phone cases will release toxic benzene and formaldehyde, which is probably better than unqualified plastic glue or adhesive. However, as for whether benzene series and formaldehyde exceed the standard, there is no legal theory because the country does not have an industry testing standard for mobile phone cases.

Benzene and formaldehyde are both human carcinogens recognized by the World Health Organization. Benzene can be volatilized at room temperature to form benzene vapor, and the higher the temperature, the greater the volatilization. In industrial and agricultural production, benzene is widely used, and formaldehyde is also a commonly used chemical raw material, due to the relatively low cost, the bonding effect of resin is better.

As for whether such volatile substances in mobile phone cases can cause cancer, there is no relevant testing standard.

Apple's own mobile phone case is not poisonous, but some factories have produced shells suitable for Apple mobile phones, this kind of shell has nothing to do with Apple, and cannot be controlled, these shells are not monitored and produced by Apple, how can it be said that it is an Apple mobile phone case.

The picture below is one of the Apple phone cases, and such a case has nothing to do with Apple.

Some of the poor quality ones are toxic and contain toxic substances such as benzene. Engineering plastics themselves cannot be said to be completely harmless to the human body, and epiphytes and so on are also harmful.

When it comes to whether the mobile phone case is toxic, it depends on the composition of the mobile phone, and the composition of the mobile phone case made by Bunsen has harmful substances, which will inevitably volatilize with the accumulation of time, but a large amount of small things!

A bad plastic case emits toxic substances when the phone heats up.

Yes, but not very harmful. Nothing big.
