Computer dermatosis initiates people's high concern
Computer dermatosis is getting more and more
White collar Miss Zhang works overtime continuously for the previous period, has 10 hours to face the computer each day, she can obviously feel one's own skin itches and likes producing oil, begin to emit small pox on the originally bright and clean face, the skin looks much duller too. The expert tells reporters, though a lot of people are unwilling to and operate these the computer to get in touch, but in the clinic, the doctors call this " computer dermatosis " . And because increasingly many young women use the computer for a long time, the skin comes to hospital by the injury to go to a doctor, doctor Yang says, it is the obscure skin that they all have a common characteristic, have the outstanding spot, some still begin to rise " Adult's small pox " .
The expert points out, because the static will make the surface of screen of the computer absorb dust and filth in a lot of air to act on, the user is like very near words that are gathered with the computer screen, a large number of dusts will drop on skin, make the pore of the skin stop up, apt long analeptic and acne; Absorbing at the same time will blot most epidermis moisture in dust and filth of the skin surface, the hot evaporation effect of electromagnetic radiation will aggravate the evaporation of the moisture even more, make the user's skin lack water. And because of the function of the ray radiation, people seem to sunbathe in the face of the computer, accepting radiation constantly, make the skin darken and is yellow, have the outstanding spot; To " only allergic " Patient say coming, be may if you can't last skin, produce by rashes red to peel the computer one ray radiationed. In addition time, in the face of computer, also can make eyes do astringent, black orbit aggravate often.

The display is released to have " Poisonous" Gas
Is it that does the radiation which people often say bring to human body uncomfortable? Professor Xiao GuoMin tells reporters, and incomplete, besides radiation, some computer displays will give out a kind of poisonous gas, cause the human body to be allergic. Show according to the 15th issue and a Swedish research of magazine of " environmental science and technology " that was published in September of 1998, it deals with a kind of fire-retardant organic phosphoric acid ester of chemical material to exceed half in the new computer screen sold before this, such chemical material can cause the allergic response.
Stockholm and Hakan Dr. Carlson of the university and his research group of the leadership have done the following experiments, determine the computer on a short time and influence that the release of such chemical material causes in long-term use separately. Researcher concentrate on, study one larger international the intersection of computer and 7 different type that Company produce amount to 18 computer screen of brand, and adopted such three phenylic phosphate (TP) by name from computer and ambient air Additive sample content. Researchers find, even the computer only spends one day, the temperature of the screen will rise to 50 degrees Centigrade - 55 degrees. At this temperature, three phenylic phosphate very easy eases produce and enter in air. They explain it is that this kind of material fails to combine together with its materials protected that the reason this kind of phenomenon take place, but at the pressure of the hot vapour, decompose to the outer surface of the computer screen, release on the air finally. The computer screen uses one week later continuously, the level which releases three phenylic phosphate can be reduced by half. Even so, call as into " the person who breathe " in the 2 range before the intersection of computer and screen Area in,183 day later phenylic level of phosphate last office three phosphate the 10 timeses of levels phenylic in the airs inners in three. Besides screen, such chemical material is used in products such as paint, lubricant, plastic and television,etc. extensively. Xiao GuoMin analyzes, according to the above-mentioned experiments, once the computer screen deals with through such fire-retardant chemical material, will volatilize the poisonous gas and bring danger to human body while starting the machine.
The expert explains, three phenylic phosphate is a kind of colourless gas with pungent taste, will stimulate eyes, skin and respiratory system, will make muscles weak and unable when the situation is serious, or there is feeling of paralysis, can cause irritated symptoms such as rash, itching, nasal obstruction, giddy, having a headache,etc. happen in the skin. The reason is that three phenylic phosphate is a kind of "anaphylactogen, after the person of the allergic physique touches this kind of gas, the loose cells in the body will release ergamine one kind of active substance when being stimulated, thus cause skin pruritus, irritated responses such as rash,etc. appear. After through taking antiallergic and applying some cortical hormone medicines outside, its pruritus symptom of skin will be obviously lightened or disappeared, but once will recur or aggravate when stopping medicines.

The new computer leaves unused for ten days and uses after starting the machine
Because three phenylic phosphate exerts an allergic influence on the human body, it will cause danger to the health to use this kind of compound as fire-retardant pharmaceutical in the outer cover of display. Xiao GuoMin proposes, the producer can start the machine for about 10 days in order to reduce the release amount of this kind of chemical early before putting the new display on market. In addition, it is a valid route too to keep the good ventilation state in using the environment of the computer.
The past 20 years, fire-retardant the intersection of pharmaceutical and output 10- 15% speed is increased progressively with every year in the world, the total volume of consumption of global fire-retardant pharmaceutical has already exceeded 1,500,000 tons at present. According to the estimation by analysis, in 2010, it is about 2 million tons that the consumption of global fire-retardant pharmaceutical will be increased to. The expert thinks, the scheme of getting a permanent cure is to popularize the use of inorganic fire-retardant pharmaceutical in the course of making the electronic product. Inorganic fire-retardant pharmaceutical has occupied the increasingly important position in the fire-retardant pharmaceutical field with the advantage of its nonpoisonous and harmless and moderate price. But in the inorganic fire-retardant pharmaceutical researching and developing at home, the main products are that hydrogen oxidize aluminium, hydrogen and oxidize magnesium etc., the variety is relatively single. And because lack superfine variety and surface treatment technology, has led to the fact the products are inferior in quality, share in market of fire-retardant pharmaceutical is not high. One that is with development and laws and regulations of the synthetic material industry is sound, and the enhancement of people's environmental consciousness, development and modifying the development trend that has already become main fire-retardant pharmaceutical of high-efficient fire-retardant pharmaceutical of environmental protection.
The doctor reminds the computer clan, especially the young women who like to be beautiful, can turn down the luminance slightly while using the computer, it is a bit farther from the display screen, can reduce the intensity of the ray radiation too in this way. While using the computer, pay attention to drinking the water and supplementing the moisture more, drinking the green tea can resist radiation too.
