Apple, millet and other brands of mobile phone protection shell is found strong carcinogens! Is your cell phone a good shell?2018-04-16 10:25:33 28 ℃
4 12 July, the Shenzhen Consumer Council 30 to market the sale of the mobile phone shell sample testing, the test results show that the number of mobile phone shell containing toxic and harmful substances, heavy metals, polycyclic aromatic hydrocarbons plasticizer, short chain chlorinated paraffins, including apple, millet and other big mobile phone shell.

, you may be curious to see the news, what harm do these substances do to the body? What is the accuracy of the experiment? And listen to the spring rain gentleman to talk to you slowly. What's the "poison" with the
288 yuan's apple cell phone shell? According to the report issued by the Shenzhen Consumer Council,
reported that Apple's 288 yuan mobile phone shell polycyclic aromatic hydrocarbons content is 94mg/kg, exceeding the standard single limit value of nearly 50 times.
(Note: naphthalene belongs to polycyclic aromatic hydrocarbons)
, at first glance, the name is still ignorant. After all, high school chemistry has been returned to teachers. What is the polycyclic aromatic hydrocarbon in the end?
actually, as long as you enter "polycyclic aromatic hydrocarbons" in any search box, more than half will follow the "pollution" two words. This is a second people all know, polycyclic aromatic hydrocarbons and formaldehyde, on our body is not what good stuff.
(picture from micro-blog
screenshot) indeed, polycyclic aromatic hydrocarbons in the biological world has long been notorious.
has no mobile phone shell as early as 1979, the United States Environmental Protection Agency (EPA) has promulgated the "priority pollutants" laws, including 16 kinds of polycyclic aromatic hydrocarbons in China, followed by the 7 kinds of polycyclic aromatic hydrocarbons in "China environmental priority pollutants blacklist".
is only because polycyclic aromatic hydrocarbons are harmful to human health. It is not only an industrial pollution source of petrochemical plants or coking plants, but also a toxic substance emitted from boiler combustion and cigarette combustion. It is now clear that polycyclic aromatic hydrocarbons on the human body has the following 2 kinds of hazards:
PAHs are found in the earliest and largest number of a class of strong carcinogen, according to the study of long-term flow disease WHO, PAHs exposure workers were more likely to have cancer, especially skin cancer, leukemia, bladder cancer, at the same time, PAHs can also cause nasopharyngeal carcinoma and gastric cancer; light induced toxic effects of
PAHs easily absorb sunlight in the ultraviolet and visible light, if they are in PAHs and ultraviolet radiation, the formation of free radicals in cells is likely to damage, cause DNA damage, which caused by the genetic information mutation.
, a mobile phone shell of millet has also been listed in
. The test report also suggested that the content of plasticizer in a mobile phone shell of millet is 0.17%, which is beyond the limit (0.1%) requirement.
strictly speaking, this value refers to the plasticizer content of phthalic acid esters in two, China has not yet been made, but the test is based on the EU standards, all products to increase the total content of plasticizer in phthalic acid esters two must be less than or equal to 0.1% per cent.

although it seems that the content of o-benzoic acid two esters is only 0.07%, but it may also cause harm to the human body.
has previously published the results of the National Toxicology Program (NTP). It has been confirmed that long-term absorption of such compounds is likely to cause liver cancer and Leydig cell tumors, and it is classified as a suspicious cancer promoter. However, the study does not confirm the carcinogenic dose of such substances. What are the craters of the
shiny mobile phone shell? Miss
mostly likes bulingbuling~'s cell phone shell, and 20~60 yuan can buy various kinds of mobile phone shells, such as drilled, woolen, dolls, etc., but the heavy metal contents in such cell phone shell accessories may be scary.
(pictures from a treasure screenshot)
took the test result of the Yue Ning brand mobile phone shell. The lead content in the transparent pink drill shell is 155000ppm, which is 1550 times higher than the standard limit.
(pictures from the consumer committee of Shenzhen 2018 mobile protective cover comparison test)
generally speaking, the daily lead absorption of human body is over 0.5mg, which can accumulate and appear chronic poisoning symptoms.
imagine, every day you put the mobile phone in the hand, put in the mouth, lead and its compounds in the mobile phone shell is likely to pass through the digestive tract, respiratory tract into the body with the blood flow into the brain, cerebellum and cerebral cortex damage caused by cells, peripheral neuritis, motor and sensory abnormalities, and may cause anemia, interstitial nephritis renal damage.

if a child put the mobile phone shell beautiful as toys, directly through the mouth to eat, it is easy to cause hepatomegaly, jaundice appears, even cirrhosis or liver necrosis.
hear here, people don't quickly check their own cell phone shell? Spring rain silently Jun send you test results of this test, if one uses a mobile phone shell is not qualified, just trash it:

selling mobile phone shell businesses may say......
most people just want to buy a protective cover for their cell phone when they buy the cell phone shell, but the cell phone shell that detects poisonous substances is believed that everyone is afraid to use it again.
however, Jun spring rain silently conjecture, several big name mobile phone shell businesses in order to restore consumer confidence (washed himself), may argue that the
of our country has not issued any quality testing standards on "mobile phone protective sleeve", does not exceed the standard problem.
actually, it looks right. At present, there are no laws and regulations in China, which stipulates the material, performance, service life and so on. This test report also SD:
Shenzhen Consumer Council test mobile phone shell using the standard for the EU in 2007 the implementation of the "registration, evaluation, authorization and restriction", Germany GS certification of polycyclic aromatic hydrocarbons (PAHs) requirements, the U.S. Consumer Product Safety Improvement Act (CPSIA) and the relevant requirements of ISO 4892-3 standard.
, however, it is an undisputable fact that harmful substances in mobile phone protective shell exceed the international average level. If merchants only add all kinds of toxic compounds to reduce production costs just because there is no relevant standard, Chun Yu Jun would like to ask: is this method really suitable?
