Proof: Does overnight water cause cancer? Is the hollow tomato hormonal? Here comes the answer.

  CCTV News:Nowadays, online rumors can be said to be changing, and new and old rumors take turns to appear. Today, CCTV news takes stock of several kinds of common false information for you, so everyone must keep their eyes open.

  01. Is there carcinogen in boiled water overnight?

  "Overnight water causes cancer", "Cold boiled water is comparable to chronic poison if left for a long time" and "Thousands of boiling water is harmful to human body" … … Recently, rumors about boiled water have been circulated again. Are these all true?

  Truth: Carcinogens are not born out of thin air.

  Experts say that mineral water and pure water that meet the safety standards have only minerals and trace elements or nothing at all. Therefore,Overnight water will not give birth to carcinogens out of thin air.. Even the carcinogen people are most worried about — — Nitrite must also be produced on the basis of nitrate.However, overnight tea will produce amino acids and other substances, which will easily lead to microbial proliferation over time and should not be drunk.

  Can I drink cold boiled water for a long time? Experts say that there is no fixed time for water to deteriorate, which is mainly affected by external objective environment such as temperature. In summer, the air humidity is high, and bacteria multiply rapidly, which easily pollutes water and causes human diarrhea. So,It is best not to drink overnight water in summer, and it is best to put overnight water in a covered container (such as a thermos bottle) in winter. Boiled water should not be left for too long, and it is best not to drink it after a few days. Barreled pure water is generally recommended to be drunk within one week.

  Except the bacterial content, other substances in the water will not change much. Therefore, as long as the water source is qualified, even if it is boiled repeatedly, the water quality will not change significantly. Therefore,There is no scientific basis for saying that "thousands of boiling water" cannot be drunk.

  02. Cann’t hollow, pointed tomatoes be eaten with hormones?

  Recently, a news about tomatoes was widely spread on the Internet. The post said, "Hollow, pointed tomatoes with red outside and green inside are all hormonal and poisonous to eat." The news made many people nervous. Is it true?/You don’t say.

  Truth: There are many reasons why tomatoes are hollow.

  Plant hormones (such as tomato essence) can really promote the fruit setting and fruit expansion of tomato, and too high concentration may lead to its hollowness. However, this is not the only reason. Insufficient light, insufficient nutrient supply, improper fertilization, excessive external temperature, improper water application and fertilization may all lead to tomato hollowness.Hollow is a physiological disease often encountered in melon and fruit planting. Hollow tomato is a deformed fruit, which is only a little problem in shape, and may taste a little bad, but it is not harmful and can be eaten.

  There are also pointed, peach-shaped, tumor-shaped and scarred tomatoes, which are mainly determined by the quality of tomato flower bud differentiation. In addition, the color of tomato is mainly controlled by genes, and the peel and pulp will show different colors by different gene combinations.None of this has much to do with plant hormones.

  What many people are worried aboutplant hormoneGrowth regulator is not a scourge, but a pesticide with extremely low toxicity. It’s completely different from animal hormones,Will not make the user precocious or infertile.Rational use can promote fruit growth. The possibility of excessive use by farmers is very low, because using too much will be counterproductive.

  03. Will the radiation from routers and microwave ovens hurt people?

  Routers radiate, microwave ovens radiate, and hair dryers radiate … … On the internet, many posts claim that these daily items are harmful to human body. Is this true?

  Truth: As long as you don’t sleep next to them, it’s safe.

  First, explain two words: radiation and electromagnetic radiation.

  Radiation can be divided into ionizing radiation and non-ionizing radiation.

  Ionizing radiationSubstances that can ionize can cause damage to cells and even DNA, which is dangerous;

  non ionizing radiationThere is no ability to ionize substances, and the energy of daily contact with non-ionizing radiation is very small, so it is difficult to directly harm organisms and it is safe.

  Electromagnetic radiation, also known as electromagnetic waves.

  High energy (high frequency) electromagnetic radiationIt’s ionizing radiation. Only this part of electromagnetic radiation is dangerous.

  wireless routerThe electromagnetic waves emitted by the router are safe non-ionizing radiation, and the frequency is mostly 2 GHz (or 5 GHz). As for ionizing radiation that can directly damage organisms, the frequency threshold is very, very high, at least reaching 100000000000000000 Hz, almost 50 million times that of 2 GHz! So, stop worrying about the radiation from the router.

  microwave ovenMicrowave is also non-ionizing radiation, which belongs to "radio waves" and can be used to heat biological tissues (such as microwave ovens). Radio waves are safe, and the electromagnetic field that can be detected outside the microwave oven is much smaller than that in the microwave oven. So, as long as you stay outside the microwave oven, it usually won’t hurt.

  electric hair dryerThe electromagnetic field generated by the hair dryer is the electromagnetic field of alternating current that we usually use. It can only form a magnetic field near the position where the current passes, and it can’t spread at all. Some data show that the magnetic field near the hair dryer is about 350 mG, while the magnetic field intensity of a common magnet is several hundred to several thousand g, which is at least several thousand times worse. So, don’t worry about the hair dryer.
