იტალიის სასამართლომ ტელეფონისგან გამოწვეული სიმსივნის არსებობა დაადასტურა

ROME | OCT. 2012 — AN RETIRED ITALIAN BUSINESSMAN WON THE RIGHT TO WORKER’S COMPENSATION FOR A BRAIN TUMOR HE DEVELOPED WHILE WORKING. ITALY’S HIGHEST COURT RULED THAT THE TUMOR WAS CAUSED BY THE CELLPHONE HE HELD TO HIS EAR FOR HOURS DAILY.

Innocente Marcolini, whose face is partially paralyzed, argued that using cell and portable phones six hours a day for 12 years while dealing with clients in China and elsewhere overseas caused the tumor on the trigeminal nerve in his head.

His lawyers presented doctors who testified that excessive cell phone use increases risk of such tumors.

Oncologist and professor of environmental mutagenesis Angelo Gino Levis, who gave evidence during the court hearing, said that the ruling was “extremely important.”

“Finally a correlation has been officially recognized between electromagnetic waves and development of tumors in spite of the anti-alarmist propaganda and research financed by mobile phone manufacturers,” Levis told the Corriere. He stressed that after working on several case studies the relationship between the use of mobile phones and the increased risk of brain tumors is proven.

Time: პედიატრების დასკვნით მობილური ტელეფონების რადიაციის სტანდარტების საკითხი უნდა გადაიხედოს

It’s been 18 years since the U.S. government assessed the standards for cell phone radiation. That was back in 1996, long before the practice of giving your big kid a cell phone became as common as giving your little kid a bath. Both cell-phone technology and cell-phone use have changed in the interim, which is why last week the American Academy of Pediatrics (AAP) urged the Federal Communications Commission (FCC) to reconsider its radiation standards.

Current guidelines specify that the specific absorption rate (SAR) — the amount of radiofrequency (RF) energy absorbed by the body when using a cell phone — can’t exceed 1.6 watts per kilogram. The standard tells cell-phone makers how much radiation their products are allowed to emit. This all sounds pretty technical; why, you may wonder, is the AAP getting involved in deliberations over RF and SARs? It comes down to children’s health and well-being, writes AAP President Dr. Robert Block, who notes that standards are based on the impact of exposure on an adult male, not on women or kids:

Children, however, are not little adults and are disproportionately impacted by all environmental exposures, including cell phone radiation. In fact, according to [the International Agency for Research on Cancer], when used by children, the average RF energy deposition is two times higher in the brain and 10 times higher in the bone marrow of the skull, compared with mobile phone use by adults.

მკვლევარები ამტკიცებენ, რომ მობილურ ტელეფონებს მამაკაცის სპერმის ხარისხის შეცვლა შეუძლიათ

(CNN) -- Keeping a cell phone on talk mode in a pocket can decrease sperm quality, according to new research from the Cleveland Clinic.

"We believe that these devices are used because we consider them very safe, but it could cause harmful effects due to the proximity of the phones and the exposure that they are causing to the gonads," says lead researcher Ashok Agarwal, the Director of the Center for Reproductive Medicine.

In the small study, Agarwal's team took semen samples from 32 men and brought them to the lab. Each man's sample was placed into small, conical tubes and divided into two parts: a test group and a control group. The control group was unexposed to cell phone emissions, but kept under the same conditions and temperature as the test group.

The semen in the test group was placed 2.5 centimeters from an 850 MHz cell phone in talk mode for 1 hour. Researchers say that 850 MHz is the most commonly used frequency.

They used the measurement of 2.5 centimeters to mimic the distance between the trouser pocket and the testes. Agarwal reasoned that many men keep their active cell phones in their pants pocket while talking on their headsets.

Overall, researchers found an increase in oxidative stress such as a significant increase in free radicals and oxidants and a decrease in antioxidants. Agarwal says that equals a decrease in sperm's quality, including motility and viability. Evidence of oxidative stress can appear under other conditions, including exposure to certain environmental pollutants or infections in the urinary genital tract.

"On average, there was an 85 percent increase in the amount of free radicals for all the subjects in the study. Free radicals have been linked to a variety of diseases in humans including cancer," said Agarwal. Free radicals have been linked to decreased sperm quality in previous studies.

However, the study does have major limitations, he acknowledged, such as the small sample size. It also was conducted in a lab and so cannot account for the protection a human body might offer, such as layers of skin, bone and tissue. Agarwal is in the early stages of further research that can model the human body's role in protecting from radio-frequency electromagnetic waves emitted from cell phones.

Agarwal also admits that there is no clear explanation of this demonstrated effect, but he shared some of his theories. "Perhaps the cell phone radiation is able to affect the gonads through a thermal effect thereby increasing the temperature of the testes and causing damaging effects in the sperm cell."

In a previous study, Agarwal and his team found that men who used their cell phones more than four hours a day had significantly lower sperm quality than those who used their cell phones for less time. Those findings were based on self-reported data from 361 subjects.

While representatives from the cell phone industry had not yet reviewed the latest study, they were careful not to give this study much merit. "The weight of the published scientific evidence, in addition to the opinion of global health organizations, shows that there is no link between wireless usage and adverse health effects," said Joe Farren, a spokesman for the CTIA-the Wireless Association.

"We support good science and always have," he said. "It's important to look at studies that are peer-reviewed and published in leading journals and to listen to the experts."

Agarwal emphasized that it is far too early for men to start changing cell phone carrying habits, noting that his own cell phone was in his pocket as he talked to CNN.

"Our study has not provided proof that you should stop putting cell phones in your pocket. There are many things that need to be proven before we get to that stage," he said.
