Artificial Winter Olympics Snow Contains’ toxic ‘Substances?The Japanese writer is making a joke


It has been more than a week since the opening ceremony of the 2022 Beijing Winter Olympics.On February 5, Tetsuya Watanabe, a Japanese economic commentator and author, sent out more than a dozen tweets questioning the use of artificial snow for the Beijing Winter Olympics.He noted that artificial snow contains high levels of DHMO, a dangerous chemical.What is DHMO?Search DHMO on the Internet, you can find a variety of nicknames for this substance, such as decarbonized formaldehyde, caustic hydrogen, zero alcohol, dihydroether, hydrophenol, dihydrogen monoxide, hydroxyl hydrogen, hydroxy acid, caustic hydrogen, dizero ether, n-oxane, ethylene oxide, hydrogen hydroxide…But perhaps the most familiar of these nicknames is H₂O, commonly known as “water.”DHMO is the abbreviation of Dihydrogen HYDROGEN.In Latin, Di and Mon are prefixes meaning “two” and “one,” respectively.”Hydrogen” means Hydrogen, and Oxide means a compound of oxygen.Therefore, literally speaking, Dihydrogen Monoxide means “two hydrogen and one oxygen”, that is, Dihydrogen Monoxide, whose meaning is self-evident after the chemical formula is written.Why go to the trouble of changing the name to DHMO when water already has a formula?It all started in the last century.In 1990, Eric Lechner, a student at the University of California, Santa Cruz, posted on the Google online forum Rec.Humor.Funny that he had discovered that their drinking water system had been contaminated with a harmful chemical called dihydrogen monoxide — a colorless, odorless substance that dissolved completely in water,It cannot be removed by any water purification equipment and may cause death if ingested.Leckner also wrote about a range of properties of DHMO, which is water, including its ability to accelerate rust, its use in animal research, and its use in the manufacturing of styrofoam.Mr. Leckner posted to the rec.Humor.Funny online forum.The post is now seen as the original source of DHMO jokes, but Leckner may have meant no harm, as rec.Humor.Funny is a forum designed to produce and share funny jokes that can’t be taken seriously.The forum describes itself as “a funny joke (in the eyes of the moderator)”.In 1997, Nathan Zohner, a 14-year-old student at Eagle Rock Junior High school in Idaho Falls, Idaho, noticed the joke while completing his school’s science practice project.The report of the unknown killer was distributed to 50 of his classmates and asked them to decide whether to do something about the chemical.In the end, 43 of the 50 students voted unanimously to take action to ban the use of dihydrogen monoxide.Zona put together an article entitled just How Gullible Are We?The “How Gullible Are We” report was picked up by several media outlets, including the Washington Post, and the DHMO’s “reputation” spread.The Washington Post reported on Zona’s project.But even so, the name “dihydrogen monoxide” has been used on and off for nearly 20 years.2012 London Olympics, weibo had a joke, said “the coach has finally admitted that gave leaf poetry taking a liquid called dhmo, to replenish energy as leaf verse”, was meant to banter questioned the Chinese national swimming team players abroad leaf verse false rumors of doping, don’t want to be a lot of net friend to take it seriously.Watanabe’s tweet wasn’t a joke, either. In a follow-up tweet, watanabe solemnly noted that the dangers of DHMO have been proven, but the results haven’t been published yet.How did the snow come from the Beijing Winter Olympics?So where does the snow come from, and will it harm the environment or the human body?Yan Jiarong, spokesperson for the Beijing Winter Olympics Organizing Committee (BOCOG), told Channel News Asia reporters at The State Council press conference on January 13 that the snow events of the Beijing Winter Olympics will mainly be held in yanqing and Chongli mountain areas, which have relatively unique weather conditions and have more natural snow.This provides a prerequisite for reducing the amount of water used to make artificial snow.According to the official website of the International Olympic Committee (IOC) on February 6, during the 2022 Beijing Winter Olympics, the ancient poplar stadium complex in Zhangjiakou is expected to have 30 centimeters of snow this year, and may use about 10 percent of the natural snow, while the snow resort in Yanqing area is almost 100 percent dependent on artificial snow.Beijing is not alone in using artificial snow at the Winter Olympics.The IOC noted that snowfall around the world has become increasingly difficult to predict in recent years as the global climate situation has changed.Artificial snow is necessary to ensure the success of the event.In Vancouver in 2010, Sochi in 2014 and PyeongChang in 2018, artificial snow was used to varying degrees.In addition, Bernhard Russi, president of the International Snow Federation (FIS) mountain skiing committee, said in a press conference earlier that artificial snow is almost necessary to achieve the perfect venues for mountain skiing.Ioc official website discussion on artificial snow for the Beijing Winter Olympics.Yan jiarong also mentioned in her speech that artificial snow is not only an emergency means to deal with the weather, but also an objective demand to ensure the quality of snow used in international major events.From the global snow events, major international events basically use artificial snow.Compared with natural snow, artificial snow can change particle size, water content and hardness, which is conducive to meet the needs of different competition venues. Moreover, artificial snow is more stable than natural snow, and it is easier to prepare the same state of snow after being pressed, leveled and injected water.From a racing point of view, the consistency of the trails also means more fairness to a certain extent.For artificial snow implementation technology, the China Association for Science and Technology science rumours platform in an article published on February 3, according to now in the market of the snowmaking technology generally has two kinds: one kind is on piece of ice, ice maker, then through crushed ice device, has made a good piece of ice broken into powder, and then through the air transport system, the formation of “snow”;The other uses biodegradable proteins to make water molecules freeze into ice crystals at above-normal temperatures.According to the relevant staff, the Winter Olympics use environmentally friendly refrigerant made of artificial snow, all snowflakes are formed by water.Snow press in operation.The 2022 Beijing Winter Olympics will use the world’s most advanced water-saving equipment and intelligent snow making system to maintain the best snow making efficiency according to the dynamic environment and avoid water waste, said Yan Jiarong.Artificial snow for the Beijing Winter Olympics will be made of the same ingredients as natural snow, and the humidity and amount of snow will be controlled intelligently, the China Daily report said.The snow is relatively low in water consumption and production costs. It’s non-toxic, so people can touch it as much as they want, and the meltwater can be recycled harmlessly after the race.Based on the available information, tetsuya Watanabe used DHMO as an article to criticize the artificial snow of the Beijing Winter Olympics.The name DHMO comes from a joke posted by an American college student on Google’s online forum in the last century. It originally means dihydrogen monoxide.Water itself is not poisonous.According to reports, the Beijing games are the use of artificial snow are needed for different events according to provisions of the international snow ski slopes corresponding technical indicators of production, its composition is exactly the same as that of a natural snow, nonpoisonous and harmless, not only can be carried out and the dosage of the dry humidity of snow and the intelligent control, can be recycled in the future, effectively avoids the waste of water resources.Source: The paper Mingcha editor: Xiao Yu
