The influence of electronic products on education Electronic products, which grew up with modern students, undoubtedly promoted a new generation of young people to learn and accumulate new knowledge. While generating positive energy, it also undeniably brought negative energy to the lives of many new people. Computers, mobile phones, iPadTouch, MP3, p4, p5, psp…… ..................................................................................................................................................... However, while more and more electronic products are filling people's lives and serving the people, some tiny hidden dangers are quietly coming.
As far as the physical properties of electronic products are concerned, the six harmful elements that pose the greatest threat to human health are lead Pb, cadmium Cd, mercury Hg, hexavalent chromium Cr6+, PBDE and PBB. Traditional mainstream electronic products all use these toxic substances, which are harmful to our health in the dark. Radiation protection, radiation protection, in recent years, this word has been used by more and more electronic products. Users are saying that it is obvious that people have realized the harm of radiation. Radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, and even induce cancer and accelerate the proliferation of cancer cells. Is it really radiation-proof? While using these products, people have adopted all kinds of new radiation protection products in the world. New products are also talking about their magical effects, and manufacturers are doing their best to update new products. However, the influence of electromagnetic waves on human beings is not a simple problem, and people cannot rule out the possibility that slight radiation is harmful to human health. And there are statistics from relevant departments, because chronic diseases caused by radiation are rising every year.
Are the negative effects of electronic products only physical? No, except adults, what will happen to growing teenagers if they don't know it correctly? Can't be described in words. Take the mobile phone as an example to talk about the harm to the growing students.
First of all, from a physical point of view, long-term radiation from mobile phones is not good for students' physical development. Professor Gail, who studies human cranial nerves and cells at the University of London, wrote that the brain cells and DNA structures of normal mice showed signs of destruction after being exposed to radio waves with a frequency range similar to that of mobile phones for four hours. Studies have shown that when children use mobile phones, the radiation absorbed by their brains is 50% higher than that of adults. Liang Xuanmei, from Lanzhou Hospital of Integrated Traditional Chinese and Western Medicine, said that many teenagers are using mobile phones now, thinking that it has little impact on their health. In fact, teenagers' immune system is weaker than that of adults, so they are more susceptible to radiation. Facts have proved that cell phone radiation can damage the brain nerves of teenagers, causing headaches, memory loss and sleep disorders. Playing mobile games often may also make children deaf, and reaching 85 decibels may damage their hearing.
Secondly, improper use of mobile phones will affect the formation of students' good quality. In recent years, it is nothing new for students to cheat with their mobile phones in various exams. In June, 2004, our school found that some students cheated with their mobile phones in the final exam. In 2004, there were cases of cheating in the college entrance examination by using mobile phones in Qianjiang, Shishou and Nanzhang, Hubei Province, such as the cheating in the college entrance examination in Dianbai. With the popularization of mobile phones and the enhancement of their functions, there are more and more phenomena of cheating by using mobile phones. And doing it more and more skillfully, such as tying headphones in your sleeves and pretending to think with your hands close to them during the exam, is essentially listening to the answers from your mobile phone. Girls are more convenient, and some simply wear headphones on their ears and cover them with long hair, which is difficult for invigilators to find. In addition, it is common for students to lie on their mobile phones. In particular, some students who are tired of learning clearly play games in internet cafes, but he lied about reviewing their lessons at school. Some students also play tricks on teachers and classmates through text messages. Deception, lying or sending false information are all dishonest. If it is not stopped in time and guided correctly, it will bring serious harm to the formation of students' good quality.
Internet cafes enter the classroom. Scientific and technological innovation in the field of communication provides a fast and simple modern means for people to exchange information and convey their feelings. With the popularity of 3G mobile phones, more and more functions can be accomplished with it. At the same time, more and more electronic products are serving everyone, and various electronic products have quietly entered the classroom. Students can surf the Internet and look up information at any time directly in the classroom. However, QQ chatting and web browsing through mobile phones have become more and more mainstream. It is no accident that the mobile phone rings frequently in class, and students send messages to each other and whisper to each other to exchange interesting information, which disturbs the classroom order.
Facing the harm of students using mobile phones and various physical and mental health problems, it has attracted the attention of all walks of life, and it is difficult to deal with it only by the original education, teaching and moral education of the school. To change the passive state of the existing school education, it is necessary to widely carry out the popularization of mental health science, social education, school education and family education, and schools should also increase mental health classes and health education classes to guide students to establish a correct outlook on life and use mobile phones correctly and reasonably.
With the continuous development of network technology, the popularity of electronic products, and scientific and technological innovation in the field of communication, more and more electronic products appear in our lives, providing a quick and simple modern means for people to exchange information and convey their feelings. Build an inestimable platform for economic construction; However, while people are enjoying the brand-new era brought by electronic products, should they also consider how to use them correctly in order to maximize their functions and minimize their negative effects? How to make our next generation use electronic products correctly for work, study and entertainment instead of indulging in online novels, online games and chatting … How to make better use of this double-edged sword? I hope more students can correctly face and use it correctly. I hope my article can remind you.
In order to increase our knowledge, broaden our horizons and use your electronic products reasonably and correctly.
Attachment: 1) Lead mainly exists in solder, printed circuit boards and incandescent lamps. Lead is a heavy metal element harmful to the nervous system. Metal lead may produce lead compounds, which are classified as dangerous substances. In human body, lead can affect the central nervous system and kidneys.
2) Cadmium has a strong accumulation in human body, which can lurk for as long as 10-30 years, and can cause "bone pain". Animal experiments show that the minimum lethal dose of mice is 50mg/kg, and cadmium entering human body and warm-blooded animals is mainly accumulated in liver, kidney, pancreas, thyroid and bones. It causes pathological changes in kidney organs and affects people's normal activities. Causes anemia, hypertension, neuralgia, secretion disorder and other diseases.
3) Long-term intake of hexavalent chromium will cause squamous cell carcinoma, adenocarcinoma and other diseases; Inhalation of high content of hexavalent chromium compounds can lead to nosebleeds, ulcers and perforation of nasal septum. Ingesting large doses of chromium can cause kidney and liver damage, nausea, gastrointestinal discomfort and other symptoms. In severe cases, the circulatory system will fail, lose consciousness and even die. Long-term exposure of parents to hexavalent chromium may also have adverse effects on the intellectual development of offspring.
4) Mercury exists in power supply equipment and light source equipment, which is a dangerous substance, an inhalation poison and has bioaccumulation effect. The impact on human body mainly affects the central nervous system and kidney system. Poisoning can lead to obvious memory loss, inattention and general weakness.
5) Polybrominated diphenyl ethers and polybrominated biphenyls are added to electrical appliances and electronic plastics as flame retardants. These two substances are carcinogenic and teratogenic, which will cause thyroid hormone disorder and fetal malformation.
