Now, more and more people like to phone "wear" on a shell, both highlight personality, but also prevent the appearance of mobile phone wear. However, CCTV "is true?" The experiment of the program investigation team shocked many people: these appearance or lovely or luxurious mobile phone shell contains carcinogenic substances. 1157.html "> Jiangsu Province Cancer Hospital experts said that formaldehyde is indeed carcinogenic, may cause leukemia, in the outdoor or ventilated environment on the body is not very small, if in bed and so small space, formaldehyde will cause damage to the human body.
Test 1: Use mobile phone 1-hour shell average 45 degrees
program group from stall and shopping malls bought plastic, silica gel and leather 3 kinds of common materials of the mobile phone shell, which, shopping malls to buy the phone shell are brand information complete products, and mobile vendors sell mobile phone shell does not label the manufacturer's name. The program group will send these mobile phone shells to the http://www.aliyun.com/zixun/aggregation/25205.html "> Tsinghua University Building Environment Testing Center indoor air testing room was tested." is the mobile phone shell really releasing carcinogens during normal use?
The program group found 6 enthusiastic citizens, asked them to follow the usual way, call, Brush Weibo, play games ... Test normal use of mobile phone, the phone shell temperature can reach how high.
1 hours later, the program group with infrared temperature tester, testing the maximum temperature of each cell phone, 6 mobile phone shell outside the maximum temperature of 39.3 degrees ~48.4 degrees. Mobile phone shell average 45 degrees.
Test 2: The phone shell heated to 45 degrees will release benzene and formaldehyde
The experimenter heated the cabin temperature to 45 degrees, then put the cell phone shell in, 1 hours later, 6 cell phone shells were heated to release the gas collected. Subsequently, the laboratory staff of these gases for benzene, formaldehyde content analysis.
6 mobile phone shells, whether in the mobile vendors or in the store to buy the phone shell, have released carcinogens benzene, released in 0.0191mg/cubic meters ~0.0494mg/cubic meters. National air quality standards for benzene concentration limit is 0.011mg/cubic meters, the experiment will be sealed when the phone shell heating for 1 hours, so that the release of benzene than the daily use of the situation higher, based on this reason, the mobile phone shell benzene release is not large. However, the purchase of plastic cell phone shell benzene release more than 0.0494 mg/cu m, and the market bought leather phone shell benzene release volume is 0.0191 mg/cu. m.
In addition, there are 4 mobile phone shell formaldehyde exceeded. The experimenter tested it in the same way, 2 silicone phone shell, 2 leather cell phone shell formaldehyde emissions are higher than the indoor air quality standards stipulated in the 0.1mg/cubic meters, of which formaldehyde released the highest amount of leather material, or even to 0.25mg/cubic meters, is the indoor Air national standard value of twice times more.
Benzene and formaldehyde are identified by the World Health Organization as carcinogens, are volatile organic compounds, will be released from the phone shell. Benzene damage to the human body is relatively large, the state has adopted regulatory measures to limit the use of benzene, more use of benzene as a substitute for benzene as an organic solvent, if the purity of these organic solvents is not high, then it may contain a certain amount of benzene. Formaldehyde may come from the use of the adhesive on the phone shell, but also may be the use of silicone shell material is not stable enough to emit. Formaldehyde is also a strong carcinogen. It is identified as 1 types of carcinogens (i.e. carcinogenic to both humans and animals).
Don't play with your cell phone in bed.
The formaldehyde in the handset sleeve can cause harm to the human body? Laboratory of Molecular Biology and genetics, Jiangsu Cancer hospital Schicker researchers told reporters that they have not done experiments, mobile phone shell, there is no formaldehyde and other carcinogens, however, there is a point to be reminded that too bad mobile phone shell, the body is certainly no good.
According to the introduction, formaldehyde is a carcinogen, long-term inhalation of large doses, may cause leukemia, and as the temperature rises, the faster the release. If the concentration is too high, people will feel dizzy and weak. If you use a mobile phone shell containing formaldehyde, in the outdoor, office and other large environment, not through the respiratory system into the body. However, if a small space, such as people often in the quilt call to send information play mobile phone, your phone shell contains formaldehyde, may affect the body.
Phone shell can't prolong phone life
In fact, the use of mobile phone shell does not extend the life of the phone. There are data shows that the phone shell will affect the cooling function of the phone, the same phone if the shell can be used for more than 3 years, and the shell to use up to 2 years. Therefore, the vast majority of mobile phone shells are not necessary.
Journalists remind the vast number of netizens, if you want to use mobile phone shell, must pay attention to purchase channels, first of all, try not to choose color too bright mobile phone shell, because brightly colored may contain a large number of heavy metals.
