Some students often use correction fluid when doing their homework, so that they inhale those irritating gases. In order to seek quick drying, some students wipe the wet surface with their hands, and the liquid adheres to the skin. Some students also use correction fluid as toys and squeeze each other. If the liquid enters the human eye, the consequences are unimaginable.
According to reports, if such products are used for a long time, it may damage the immune function of the human body, and more seriously, it may lead to complications such as leukemia. Someone once put cotton soaked in dichloromethane, trichloroethane and p-xylene next to two groups of mice. The mice in the group with more reagents only died of convulsions within 5 minutes, while the mice in the group with less reagents were tested for 5-8 minutes every day. Within 5 days, the mice were flustered, ate less, moved slowly and lost weight, while the control mice without correction fluid had normal weight. In addition to correction fluid, ballpoint pens with strong fragrance, stationery with strange shapes and luminous stationery mostly contain formaldehyde. Long-term exposure can cause chronic poisoning. Experts suggest that it is best not to let children touch it, do not use correction fluid, and do not use non-stick glue.
Professor Shang Jia, deputy director of the Henan Hepatology Branch of the Chinese Medical Association and director of the Department of Gastroenterology of Henan Provincial People's Hospital, said in an interview that according to the survey, the incidence of minors is obviously on the rise, which is inseparable from people's excessive exposure to chemicals in their lives. For example, some students use toxic learning tools, which are very bad for children's growth and development and have potential harm. On the surface, it has little effect after use, but it may get sick in adulthood. Therefore, students should choose stationery from the perspective of safety, health and practicality. It is best not to use stationery with pungent smell, not to blindly pursue beauty and fun, but to consider it from the perspective of environmental protection, health and practicality.
At present, most primary school students use correction fluid.
How many students are using correction fluid? Do they know that the correction fluid is poisonous? The reporter conducted an interview on this.
At the gate of a primary school in Huayuan Road, Zhengzhou City, when a fourth-grade pupil bought correction fluid, the reporter asked him why he bought this school supplies and whether he knew it was toxic. He said: "Most students in our class have it. It has been used for more than a year, and no one is sick with correction fluid. "
A fifth-grade pupil told reporters that his father had read CCTV's report on the correction fluid and knew that the correction fluid was toxic. "But we are all used to it. When you use it, stay away from it and don't let the smell float into your nose. "
In a primary school in Jingsan Road, the reporter investigated 85 students in a class and found that 60 people were using correction fluid, and only less than 10 people knew that it was toxic.
Correction fluid is not only used by primary school students, but also by many middle school students. When the reporter was investigating in a middle school in Zhengzhou, a female student named Qian Qian said that nearly half of the students in her class had correction fluid, but they didn't use it as often as primary school students, and they only needed it if they made mistakes in their homework occasionally. As for toxicity, she also learned something from recent news reports, and felt a little alarmist: "If it is so toxic, why does the country let it produce?" Why not close the manufacturer of correction fluid? "
Most of the correction fluids investigated are "three noes" products.
Yes, since the correction fluid is so harmful, why don't the relevant departments ban production? In the investigation, the reporter found that most of the correction fluids are "three noes" products, and there is no factory name, address and production certificate. In a stationery store on Wei Wu Road, the reporter said that he wanted to buy a tube of correction fluid. The shopkeeper immediately took out three kinds of correction fluid from the counter. Two kinds of correction fluid are written in English, and only one is written in "Bai Tong" correction fluid. There is no name or address of the manufacturer. The reporter casually asked the shopkeeper where he came in. The shopkeeper smiled and said, "Don't worry about buying it. I have been selling it for several years, and 2.5 yuan is very convenient to use. " When the reporter suggested that this was a "three noes" product, the shopkeeper said that the first two products were wholesale in Commodity City, and "Bai Tong" was specially delivered to the door for sale.
Subsequently, the reporter saw in several stationery stores in Huayuan Road, Shangcheng Road and Jiaotong Road that there are still many types of correction fluids, some in tubes and some in small bottles. According to rough statistics, there are 15 kinds, of which only two kinds of correction fluids named "correction fluids" have the name, address and telephone number of the manufacturer on them.
In the commodity city near the railway station, there are a wide range of correction fluids, most of which are written in English, and some of them are marked with the words "environmental protection" in Chinese. Mr. Xu, the stall owner, said: "Most of these correction fluids are imported from the south. Wholesale is very cheap, less than one yuan, and it can sell two or three yuan at the school gate. " The reporter asked him if he knew that the correction fluid was poisonous. He smiled and said, "Of course, I don't want to smell it when I sell it. However, you can buy something with small fragrance, low toxicity and pungent smell. "
It is understood that at present, the national mandatory safety standard "General Requirements for the Safety of School Supplies" is being drafted and is expected to be implemented next year. This regulation covers almost all the safety technical standards of stationery, including the limit standards of eight harmful heavy metals such as lead, mercury and arsenic. It will also stipulate that stationery should not have sharp edges, burrs and thorns, and children's scissors must be round heads.
It is suggested that students should be allowed to make mistakes.
During the interview, many parents of students were very worried about the use of correction fluid by their children. I hope the school can take some measures to get rid of students' dependence on correction fluid, such as not using correction fluid in class, not using correction fluid in homework, educating students about the harm of correction fluid and so on.
Seeing that more than half of the students in the class use correction fluid, Zhang Liping, the head teacher of Class 3 (2) in Wei Wu Road, Zhengzhou City, also felt that the problem was serious. After consulting with several class cadres, he put forward the following initiatives to primary and secondary schools in the city.
We are primary school students in Grade Three, and we started to use pens this year. We found that some students use correction fluid after writing typos, but it is not conducive to our growth:
1. correction fluid is a chemical synthetic product with irritating smell. We use pens every day to study, and long-term use of correction fluid is harmful to our health.
2. Some students regard correction fluid as a toy, which will distract them from playing in class.
The exercise book is coated with correction fluid, just like pieces of white plaster, which is not beautiful.
4. It will form dependence on correction fluid, which is not conducive to developing good writing habits.
Therefore, we issued an initiative to primary and secondary school students in Zhengzhou, and we must be calm and concentrate on writing homework; After writing the typo, make a small cross or draw a diagonal line. I hope everyone will stay away from the correction fluid and make our homework clean and tidy.
