The correction fluid has not been broken and the students have never stopped using this kind of thing. A primary school student said that the correction solution was used to keep the textbook neat and clean. In order not to let the textbook "ugly", the correction fluid had to be used. Then, whether the correction is poisonous or not, the reporter did the experiment to let the lively mice and the correction fluid live for five minutes, and the mice couldn't even walk away.

"many school teachers now remind students to try not to use corrections, but do not explicitly prohibit use." Ma, the three grade of a primary school in Shinan District, told reporters that "the school has played a guiding role and has not acted as a compulsory forbidding role."
according to teacher Ma, in the class that he taught, a few years ago, the students who used the correction fluid were still very much, and now it began to slow down, but it still accounted for more than 30%. On the two day of January 10th and 11, the reporter visited many primary schools in the island city, and the answers were not the same, but in general, there were still a lot of use of the correction fluid.
this phenomenon can be drawn not only from the teachers and students, but also from the small toy shop beside the school. At noon on 10, it was time for school to go to school. The students of a primary school in Anshan walked out of the stationery store on the campus. "There are many stationery stores on our side. The sales of the corrected liquid are good, because the students are also many." Mr. Zhang, the owner of the toy shop, told the reporter.
Mr. Zhang pointed to the next shelf. The reporter saw that there were more than ten kinds of correction fluid on the shelf. According to different brands, it was divided into different grades. The price ranged from two or three yuan to more than ten yuan, but many products were not even in Chinese, even there were no manufacturers and contact ways. Boss Zhang told reporters: "a little bit better has pungent flavor, that kind of perfume is very strong correction fluid is not good, is not good for the body."

correction fluid toxic, students know, parents know why the toxic things can go on the campus.
Li Minghao (pseudonym) is a student of grade four in primary school. His achievements have always been excellent. He has become an object for other students to imitate. He told reporters that he was in contact with the correction fluid when he was in grade three. At that time, Li Minghao began to write with a ball point pen. Try using the correction fluid. " At that time, it was quite fresh. It took more than six months. Later, the teacher refused to use it, saying that it was easy to form bad habits.
Ma Jun (pseudonym) is Li Minghao's teacher, her view is that the correction fluid is not conducive to the students to develop good writing habits, in addition to the prohibition of some tests, teacher Ma's view is to suggest that students do not use it. "The school does not have the relevant regulations in this respect, saying that the correction fluid can not be used, and the teacher can not force the students to use it. If the students insist on it, the teacher has no way to do it."
later, the reporter interviewed the president of Li Minghao's school. The headmaster told reporters, "the correction fluid is a stationery, it can be found in the relevant regulations. Now the correction fluid on the market is not good for the students, who knows, but it is like a pencil, and we can't disable all the stationery." "."
[b] interpretation of [/b]
[b] toxic substances can be carcinogenic, students should be careful to use [/b]
the debate over the forbidden solution has been a long time, the experts have done testing found that the correction fluid contains dichloromethane, three chloroethane and para xylene and other substances. In April 2008, the general requirements for safety of student products were put into effect. However, for two years, no obvious effect has been achieved in the correction fluid.
according to the staff of the Municipal Quality Supervision Bureau, after the implementation of the general requirements for the safety of students' articles, the label of "GB" should be tempted to make it easy to distinguish, but the reporter saw in the investigation for successive days is not optimistic. The smell of the nose is very popular with students.
industry insiders say, "the modified liquid is very toxic. It is not recommended for students to buy. "
the reporter has found that some experts have detected this correction fluid, usually containing dichloromethane, three chloroethane and para xylene, and the auxiliary materials are titanium dioxide and essence. These substances are easily volatile in the air, especially when gaseous p-xylene is inhaled, it can cause chronic poisoning, causing headache, drowsiness, nausea and so on.
dichloromethane and three chloroethane, such as the nervous system that infringe on the human body, will cause drowsiness, dizziness, anorexia, slow action and so on. When inhalation is too much, it can cause discomfort, convulsion, and difficulty in breathing. The rescue will not cause serious harm to life in time. The correction fluid is popular because it is done quickly after it is painted, because it contains highly volatile organic hydrocarbons, which is why it strengthens its toxic permeability and causes more obvious damage to the health of the children.
reporter in the entrance of a primary school to buy the correction fluid to write notes: stay away from infants, not to suck, pay attention to ventilation, avoid high temperature, away from the fire source.
[b] reporter experiment [/b]
[b] seven or eight minutes smoked white mouse [/b]
to explore whether the correction fluid is poisonous, the reporter bought a small white mouse in the Nanshan market, and did the experiment.
before the experiment began, the reporter first fed the mice bought from the market and fed them enough sleep. After waking up, it looks very energetic and runs around the table.
the experiment began. The reporter cut off the correction fluid bought from the sales department from the bottom, dripped the fluid out on a silver plastic bag, flapping an unpleasant smell and found a glass bottle on the flowing correction fluid. After about 30 seconds, the reporter put the mouse in the bottle. It may be that the scent in the bottle is very bad. The mouse is particularly unfit after entering it. At first he is at a loss. After a few seconds, it becomes impatient, desperately searching for the exit, and digging the bottle with his claws, and trying to run out of it.
about 30 seconds later, the liquid began to harden, the edge was basically dry, the mouse was anxious to find the exit, and the dry liquid was picked up everywhere.
during the hasty period, the mouse also bites the plastic bag under the ground and bites a few of the white correction fluid and eats it. The liquid on the corners of the mouth is more irritable and it wants to erase the liquid. The whole process is very irritable. After a minute, the mouse became tired and stopped breathing. It could feel that it could not bear the peculiar smell in the bottle.
to ensure that there is enough oxygen in the bottle, the reporter exposed a three cm gap at the bottom of the bottle to ensure air circulation. During this period, the mouse looked for an outlet around the bottle, but the movement became slower and slower. After seven or eight minutes, I took a few mouthfuls of liquid, and the pace of walking was somewhat unstable. When he took it out of the bottle, he didn't feel any excitement from the bottle. After a few steps, he didn't stand up and fell to the ground. It walked a few more steps and might feel a little tired.
about half an hour later, come back to look at it. The mouse is huddled in a corner of the table and touch it with his hand. It just looks up slowly, and crouch. This is in sharp contrast to the lively jumping before the experiment.
before the press release, the mice remained unconscious, but the situation gradually improved.
[b] reporter [/b]
[b] can not let it "change" the health of the child's health [/b]
talking about the correction fluid, the reporter remembered his own school, at that time, there was a kind of "slippery flow" correction fluid, as the name of the stars like a lot of students sought after.
after several days of investigation, the reporter found that after ten years, today there are still different brands of correction fluid, and there are still many students using it. A primary school teacher said the school was opposed to use. In 1999, the Chinese Consumer Association issued a warning to minors: pay attention to self protection, be vigilant for chronic poisoning, and let the correction fluid "change" the health of the children. Although the school has no rigid rules that can not be used, it has been educating children not to use it from the side.
why is the child so unpersuaded? Don't you know it's harmful? "Do not correct the liquid, write out the wrong way directly, and affect the beauty. The teacher wants the homework to be clean." One student told the reporter. Use the correction fluid for the work of the clean, perhaps this is the teacher's regulations, but the writing homework must be wrong, what is wrong? The child has to choose to continue to use the correction fluid, the beauty is important, but the healthy living habits are more important.
