　　In recent years, I have often met some friends who sent me some pictures of potted plants, saying that I suddenly saw on the Internet that they were carcinogenic plants, but I happened to have them at home. I am very worried. Do you want to throw them away? Some micro-friends even sent links to articles, such as "Don’t leave these 52 kinds of cancer-causing plants at home", "Please stay away from these cancer-causing plants" and "80 kinds of common toxic or cancer-causing plants" … What’s more, it is said that a couple of flower farmers who have been planting flowers for a long time in Foshan City have suffered from nasopharyngeal carcinoma.

　　For a time, flower friends talked about the change of colors, "expelling the culprit of cancer" and "cleaning up the door", which meant that these plants were wiped out. In fact, is this really the case?

　　The statement comes from a paper nearly 30 years ago.

　　It is understood that this statement originated from a paper "Screening of Chinese Herbs and Plants Inducing Early Antigen Expression of Epstein—Barr Virus" by Academician Ceng Yi from Institute of Virology, Chinese Academy of Preventive Sciences. According to the article, "1693 species of plants (Raji cells with EB virus as experimental objects) were screened, and 52 of them were found to have the effect of inducing the early antigen expression of EB virus". And these 52 plants happen to be the "52 carcinogenic plants" transmitted by the Internet.

　　This paper was first published in 1992, almost 30 years later. The news of cancer-causing plants still appears in tabloids, Weibo and friends circle from time to time, and is often mentioned by people. Let the flower growers tread on thin ice, and create many unjust, false and wrong cases of flowers and plants.

　　Epstein-Barr virus is a virus isolated from people with lymphoma. 90%-95% people have been infected by this virus, but most of the time it will not affect human health. Only under the external stimulation, EB virus will suddenly "wake up" and start to replicate in large numbers, which will make the signal pathway controlling normal differentiation and proliferation in cells abnormal, thus causing cancer. Horribly, the activity of EB virus will promote other carcinogenic viruses (such as SV40 virus) to start activities.

　　It is found that the secondary metabolites produced by some plants can activate EB virus, make it wake up and become an active replication state, so these secondary metabolites are called "cancer-promoting" substances. For example, croton oil extracted from croton seeds has a strong ability to induce early antigens of EB virus.

　　However, it can be seen from the above description that plants themselves do not produce EB virus, and even some cancer-promoting substances released into the soil through fallen leaves or roots are only accomplices, not masterminds, in causing cancer. Therefore, the statement that these plants "contain carcinogenic viruses" on the Internet is groundless and a misunderstanding of scientific papers.

　　Plants containing cancer-promoting substances can still be domesticated.

　　Can 52 kinds of plants containing cancer-promoting substances detected by academicians still be raised in their own homes? This is probably what all flower lovers are eager to know.

　　The answer is, of course, yes. These plants, if you don’t eat them and maintain them normally at home, will not cause harm to the human body.

　　If these chemical cancer-promoting substances in plants are taken out and identified, they are just secondary metabolites of plants, and they are a large number of chemical synthetic products with complex structures that are not directly involved in plant growth and development. Plants use these compounds to improve the body’s ability to resist the invasion of the external environment, such as driving away hateful pests, transmitting useful information between plants, dealing with diseases and various unfavorable factors in the surrounding environment, and attracting "matchmakers" or "bodyguards" who help themselves pollinate …

　　Human beings are no strangers to the secondary metabolic "products" of plants, such as rubber, spices, essential oils and so on. The content of these secondary products in plants is not high. Most of the time, they stay quietly in plants and are released only when plants are in danger or their limbs are damaged. Only when these products enter the intruder’s body will they have the effect of poisoning or driving away; For flower growers, only when they enter the human body can they induce cancer.

　　Emphasize that it only induces cancer and promotes cancer, but it is not carcinogenic.

　　Some people may ask, I usually don’t eat potted flowers or move potted flowers, so will the secondary metabolites in these potted flowers float in the room in the form of gas, thus promoting cancer?

　　"It’s all hooliganism to talk about toxicity regardless of dosage". Generally speaking, the secondary substances in plant defense system have large molecular weight and poor volatility. Unlike esters and alkanes which are easy to volatilize in plants, they are mostly water-soluble secondary substances, and almost lose their volatilization ability in plants with high water content. The dose that can be volatilized into indoor air is very small, and they pose a cancer threat to people, even less than smoking a cigarette and breathing automobile exhaust.

　　In the book "Volatile Gases from Plants and Human Health and Safety", the volatile components of Rosa davurica, one of the "52 Carcinogenic Plants", were detected. The results showed that no cancer-promoting components were detected in its volatile components. Therefore, flower friends only need to know the properties of these plants and the characteristics of toxins in their bodies, and they can coexist peacefully with these plants without any burden without touching or eating them.

　　Three so-called "carcinogenic plants"

　　As long as you don’t eat, you can rest assured.

　　Let’s find out three so-called "cancer-causing plants" that are common indoors in northern China for the time being, and here we will break them down one by one.

　　dripping guanyin

　　Drip Guanyin is very suitable for keeping indoors. Staggered leaves, shaped like cattail fans, protrude from the base of brown leaves wrapped in layers, giving off a shiny luster. Drip Guanyin is resistant to shade, and its huge leaf surface can absorb dust and toxic gases in the air. Watered enough water the night before, and got up the next day to observe the leaves. There must be glittering and translucent "water drops" hanging on the tip of the leaves. That is, use toilet paper to absorb the water droplets on the tip of the leaf, and in a short time, a "pearl" will be hung on this part.

　　This is because the dripping Guanyin, which originated from the bottom of the tropical rain forest, can "sweat" like a human being. When it feels hot and humid, and there is too much water in its body, it will excrete the water together with the toxin alkali secreted by pests through its own catheter, and condense it into "water droplets" at the tip of the leaf. This water drop is actually the secret weapon of dripping Guanyin. Small insects that come here for food will be doomed if they drink this honey dew as dew or accidentally touch it. Drinking "honey dew" will make small animals’ mouths red and swollen or suffocate because of heart paralysis; Once the honey dew touches the skin, the skin immediately itches and swells; If the eyes touch the "water drops", it will cause severe conjunctivitis and even blindness … People accidentally touch it, and it is the same symptom. It is also reported that some people saw that the massive stem of Drip Guanyin was very white, a bit like a potato and watery, so they couldn’t help licking it and wanted to taste the juice inside. I didn’t expect this lick to bring disaster-swollen lips, sore throat and numb tongue.

　　In fact, in plants, it is very common that the roots and leaves of plants contain toxins. The dripping Guanyin belongs to Araceae, and most of the plants in this family are poisonous, such as tortoise-back bamboo, evergreen and green radish.

　　crown of thorns

　　Red flowers, rising slowly from the hard and pointed cone thorns, are delicate, charming and graceful. During the Spring Festival, the blooming Rosa davurica will add a lot of spring scenery to the living room, which is also the reason why northerners love Rosa davurica. It is not afraid of drought, waterlogging, shade and sun, and it is very easy to feed.

　　Its vitality is super strong: if you don’t water it for half a year, you won’t get the sun, but you can live in a decent way, and the cute little buds with pink branches will bloom again. Even if you cut a branch and let it lie on the ground, you can grow roots, and green buds will burst out on the branch.

　　Rosa davurica, also known as begonia, is a member of Euphorbia in Euphorbiaceae. Euphorbia plants have a common feature: white milk will be secreted from the wound after the plant is injured. This kind of milk is a diterpenoid compound with special structure, which is toxic. This is also a "sharp weapon" for such plants to protect themselves and prevent pests and diseases from invading during the evolution process. The white milk secreted by the "wound" of Rosa davurica also stimulates human skin and mucous membrane. Eating it by mistake will cause nausea, vomiting, diarrhea and dizziness.

　　iris

　　Iris, which we often say, is not a plant, but a general term for iris plants. Its German Iris, Iris, Iris and Cynthia are all called Iris in principle.

　　Iris plants have bright and beautiful colors. The Latin name iris comes from Greek and is the name of Iriz, the goddess of the rainbow. It can be seen that the colors of iris plants are as colorful as rainbows. It is common to have two or three colors on a flower, which is the eternal darling of horticulture. According to the internet, the rhizome of iris can be used as emetic and cathartic, and can also be used as medicine to treat dizziness and toxic swelling. Eating its flowers, leaves and roots will cause gastrointestinal congestion and severe diarrhea.

　　As can be seen from the above examples, whether these plants cause cancer depends on whether you eat them or want to grow them in flowerpots for viewing. If it is only the latter, you can raise these plants with peace of mind. According to some data, 97% of the 368 kinds of flowers planted at home are beneficial to human health. Of course, we have to emphasize the four basic principles of peaceful coexistence with domestic plants-no matter what flowers are raised at home, don’t import them; Try to avoid zero-distance contact with plant secretions; Wash your hands after handling plants; Open the doors and windows to let the air circulate.

　　Zhongxin. com, Hangzhou, September 29 (Reporter Zhang Yuhuan) On the 29th, the reporter learned from the Zhejiang Meteorological Observatory that according to the latest meteorological data analysis, it is expected that during the National Day holiday this year, Zhejiang Province will be successively affected by typhoon Mina and weak cold air, among which the province will usher in stormy weather from 1 to 2, and the typhoon center may have 14 to 15 winds passing through the sea.

　　The National Day holiday coincides with the growing autumn in Zhejiang. The temperature is generally suitable, but the daily temperature range is large. The average annual temperature in most parts of Zhejiang is 20-22℃, the average precipitation is 15-40 mm, and the average precipitation days are 2-3 days.

　　With the approaching of Typhoon Mina, the 18th this year, the National Day holiday in Zhejiang will also usher in a stronger autumn. On the 29th, the typhoon was strengthened from a tropical storm level to a strong tropical storm level. It is expected to pass the northeast of Taiwan Province Island on the evening of the 30th, and then gradually turn to the north and move towards the north-central coast of Zhejiang.

　　Influenced by Typhoon Mina, Zhejiang Meteorological Observatory predicted that the wind power in the southern part of the East China Sea will start to increase from the 29th, and there will be 11-13 winds in the East China Sea from the 30th to October 1st, and 14-15 winds in the nearby waters where the typhoon center passes, and the wind power in the coastal waters of Zhejiang Province will gradually increase to 10-12, and 13-14 in some areas. There are also 7-9 winds in some inland areas of Zhejiang Province, and there are heavy rains and heavy rains in eastern Zhejiang and parts of northern Zhejiang.

　　From October 3rd to 4th, Zhejiang Province was dominated by cloudy weather, with the highest daily temperature of 32-34℃ in most areas. From October 5th to 7th in the latter part of the holiday, affected by the weak cold air in the north, there was weak precipitation in some areas of Zhejiang Province, and the temperature dropped slowly. The lowest temperature in the morning of October 7th was 16-19℃.

　　The meteorological department reminded that during the National Day holiday, there were heavy rains and heavy rains in eastern Zhejiang and northern Zhejiang, and there were strong winds at sea. Relevant departments should pay attention to preventing the adverse effects of strong winds at sea on island tourism and maritime traffic. From October 3rd to 7th, the weather conditions in Zhejiang Province are generally favorable for leisure travel, but with the influence of cold air moving eastward and southward, we still need to pay attention to the obvious cooling and weak precipitation process.

Many people ridicule that it is the next generation of network car, which is not expensive to sell and the configuration is OK. The key is that it has low energy consumption and good economy! In fact, Tucki’s previous car energy consumption control was also good, but the latest MONA heard that it was even worse. We are also very curious about the level of power consumption and endurance achievement rate of this car.

Therefore, we have arranged the endurance test of two scenes simultaneously, one is the high-speed road test, and the other is the urban road test. Besides this endurance test, I have been driving this car back and forth for several days, so I can give you a more comprehensive experience.

First of all, the endurance performance, we still follow the test route of previous tests, located in Nanda trunk line. On the test day, the outdoor temperature was about 32 degrees Celsius, the fast-charging pile was fully charged, the kinetic energy recovery was adjusted to the maximum, the driving mode was adjusted to the energy-saving mode, the air conditioner was adjusted to 24 degrees Celsius to circulate the automatic wind, and the subtotal mileage was cleared, and the tire pressure was maintained at about 240kpa.

Nanda trunk line is a relatively long expressway with a speed limit of 80 km/h. After we are fully charged, we basically run around this road. Except for turning around at both ends and waiting at traffic lights, they are basically driving near the speed limit, but in the end, the average speed is about 60km/h, which can better represent the daily commuting power consumption.

The car we got was an entry-level version of the 515 endurance car, but when the endurance reached 0%, it drove 518km. At this time, the achievement rate exceeded expectations, and it ran for another 9 km until the power was limited. The final result was locked at 527km, and the endurance achievement rate was 102%. The meter showed that the power consumption was 9Wh/100km, which showed the last 100 km, but even if it was calculated according to the electricity, the 51.8-degree electricity ran 50 km.

And on the day of the test, my colleagues in Beijing also took a Tucki, 620 model with a long battery life, and they went directly to the high speed, holding up the live broadcast test at a speed of 120km/h, and finally the power consumption per 100 km was 12.6kWh/100km, which was also very low.

And this 515km version of Tucki, I have experienced five days back and forth, and I have also driven violently, and the power consumption is in the early 14kWh/100km. Therefore, if I drive steadily every day, this endurance performance can be achieved by anyone, which is enough to show that the power consumption of MONA M03 in Tucki is superior to that of the trams on the market at present, regardless of the middle and high speed scenes.

It is also the lowest power consumption among the models we are currently testing.

Some netizens think that the price of this car’s low power consumption is weak power. In fact, to be honest, the control of this car is more advantageous for the same price model, and the feelings of the three driving modes are also different. The economy and comfort modes are similar, but the comfort mode will have a little stronger power in the front and back stages, and the sports mode will be full of power from the beginning.

Kinetic energy recovery can be closed and adjustable in three gears. High kinetic energy recovery will nod a little after releasing the throttle, and it needs to be adapted to the body. It is recommended to open it in the middle and low for daily driving to ensure the comfort of the body and improve the battery life.

MONA in Tucki is relatively easy to drive as a whole, and it is not quite the same as Tucki before. In the past, even if the steering wheel was turned to sport mode, the overall feel was still light, and the medium and large SUVs like that were also very light, while MONA’s steering was obviously much tighter, and the switch damping seemed to be tighter.

Chassis can be regarded as the normal level of this level. The former McPherson rear torsion beam is relatively resilient when passing through some speed bumps at low speed, and it is quite satisfactory for filtering fine vibrations. It will feel less comfortable when encountering relatively large ups and downs, but the overall afterlife is still in line with the tonality of this price.

The layout of the whole car is very simple. There is only one screen in the central control area, and there is no instrument. The overall operation logic is more like the old Tesla, and the operating system interface is relatively simple. Fortunately, most operations can be realized by voice, but this voice does not seem to support multiple voice commands. Only 1-2 commands can be completed at a time, but the recognition accuracy is still ok.

Then the automatic parking recognition rate of this car is average, but as long as most parking spaces are recognized, they can basically be listened to well, and there are 360 images, which can also help you park in reverse, but the rear camera position is low, which may be covered by mud in rainy days. It is best to wipe it in rainy days.

In terms of intelligent driving, this version of my test drive does not have high-speed and intelligent driving in urban areas, but it has a lane intelligent cruise mode, which can drive at the set speed when the lane is set. If you encounter a vehicle in front of you, it will automatically accelerate and decelerate. To a certain extent, it can still better alleviate fatigue, but the power consumption will increase slightly after opening.

In terms of space performance, Tucki is relatively in line with his size, but personally, he feels that the seat cushion angle of the whole vehicle is relatively straight, especially in the back row. Then the spatial performance is basically the performance of an A-class car. The sitting posture of the main driver will be higher than that of the fuel car, and the driver’s seat needs to be adjusted to a slightly larger angle to be more comfortable.

Generally speaking, this car is very cost-effective in the price range of 120,000-150,000. Not only is it low in daily energy consumption, but it is also relatively easy to drive. At the same time, its experience and convenience are relatively advanced. It is perfect for daily urban transportation. I wonder if you are satisfied with the performance of this car? Let’s discuss it in the comment area!
