The old lady in Changshu prepared pickles with snowmelt salt.

Salt can melt snow, but the salt used for melting snow is different from the edible salt we usually use for cooking. Snow melting salt belongs to industrial salt, and people will be poisoned if they eat it. A few days ago, there was snowfall everywhere, which affected people's travel. The sanitation department used melted snow salt to clean up the snowflakes. As a result, the melted snow salt in Changshu, Jiangsu Province was taken away. It's really urgent! If you eat by mistake, the consequences will be unimaginable!

1, the old lady pickled pickles with snowmelt salt.

On the afternoon of October 24th, 65438/KLOC-0, the Meteorological Observatory of Changshu City, Jiangsu Province predicted that there would be a heavy snowstorm in the city from that night to the 25th.

Emergency measures will be initiated immediately.

At about 4 pm that day, Meili Town Construction Bureau arranged for salt workers to put industrial salt on each bridge in advance for use. Among them, Meiliqiao put six bags of salt, each bag 100 kg.

An hour and a half later, Meili Town Police Station received a report that the industrial salt on Meili Bridge had been taken away.

The police station quickly sent someone to inspect the scene. However, due to the blind area on the bridge deck, there are several bags of salt scattered around, so it is impossible to confirm how many bags have been lost. After contacting the salt worker, it was finally confirmed that two bags of salt were taken away.

That night, Weibo, local TV stations and Changshu traffic police released salt search information. "Salt is an emergency material to ensure smooth traffic in freezing rain and snow. It is illegal to take it for yourself, and it is even more inedible. Please spread, it is important to save people. "

After research, the staff of the police station found that the bag of salt was taken away by a passerby riding a tricycle at 4: 30 in the morning.

At 3 o'clock in the afternoon, the staff of the police station finally found Yang Cuilian who took the bag of salt for the second time. She said that she had thrown it away without eating it, and found the discarded salt near the trash can with the staff of the police station.

As for the other bag of salt lost, the staff of the police station found through video investigation that it was taken away by a three-wheeled battery car at 7: 40 on the morning of 25th.

At 2 o'clock in the afternoon, the police found the whereabouts of this bag of salt-Shenshi Village near Meili Town 10 km. Since Mrs. B was not at home, her motive for taking salt could not be confirmed, and the police then brought back the unopened salt.

So far, two bags of industrial salt that were robbed three times were recovered after missing for more than 20 hours. "No one has eaten by mistake."

Marinate vegetables with salt

At 3: 30 in the morning on the 25th, Yang Cuilian got up and went out. She makes steamed buns in a breakfast shop 2 kilometers away from home. She goes to work at 4 o'clock every morning and gets off work at 10: 30.

She rides an electric tricycle to work every day. She first turned out of the community, drove for two or three minutes, crossed Meiliqiao, and walked more than 500 meters.

According to the news of Changshu Meteorological Observatory, at 0: 07 on October 25th, 65438/kloc-0, the Meteorological Observatory issued a yellow warning of blizzard. It is estimated that there will be more than 6 mm of heavy snowfall from midnight to daytime after the 25th, and the snow is obvious.

According to the records of the police station, Yang Cuilian didn't open the Meili Bridge until around 4: 0017 on the 25th. At about 4: 30, she loaded a bag of industrial salt into a tricycle and drove off the bridge.

"I was passing by the bridge and saw (industrial salt). I want to see what it is. I tasted one. It was salty. Now that we have good salt (refined salt), we don't eat this kind, but we can still eat this kind of kimchi when we were young. " The old lady Yang Cuilian recalled.

Industrial salt is one of many snow melting agents. It is difficult for salt to form ice when dissolved in snow water, and traffic accidents and traffic jams can be avoided to some extent in rainy and snowy days.

However, industrial salt is essentially crude salt without refining, which may contain toxic heavy metals and even a nitrite to slow down corrosion. If the latter is ingested at 0.2-0.5g, it may cause poisoning, and if it exceeds 3g, it may lead to death. According to the official understanding, the old lady A who took this bag of salt back before Yang Cuilian was also for pickling pickles.

"(Pickled pickles) are coarse salt, which is thinner than industrial salt, but they are very similar and difficult to distinguish. Bacon is cooked in the countryside now. If you do more, you will still use raw salt. " Zhong Jiandong, director of the Party and Government Office of Meili Town, later introduced that he used to work in the field of food safety.

But Yang Cuilian doesn't know this. Although the salt bag was marked "no food", she said that she could not read, and she went to work with industrial salt in her car. About six hours after going to work, the salt bag was kept in the tricycle parked outdoors, and no one reminded her that it was toxic industrial salt.

In the afternoon, before Yang Cuilian's husband went home, he heard on the road that the police were looking for salt in their own community. Neighbors in the community recalled that Yang Cuilian's husband was very angry later and severely scolded Yang Cuilian. The old lady A had been scolded like this before.

So, before the police at the police station found herself, Yang Cuilian had thrown the salt into the trash can of the community.

After the police took the bag of salt away, Yang Cuilian's family buried a small amount of spilled salt in the stone trough in front of their house.

"How dare you do such a bad thing of stealing? No one else picked it up. It is something on the bridge. " An old man in the community who claimed to know Yang Cuilian was a little angry.

Another neighbor said that Yang Cuilian's family (economic) conditions are good. This time, she took salt mainly because she didn't know that she couldn't eat it. "She was greedy for that cheap."

The owner of the breakfast shop didn't want to be interviewed at first, but in the end he couldn't help but comment: "She has worked for me for five or six years and never takes anything from others."

This breakfast shop in 7 yuan sells a cage of fresh meat buns, both of which are 0 yuan 65438+ 1. The boss's personality is very casual, and he just smiles when he is pointed out that the name of the store is upside down.

Yang Cuilian's chubby figure was put into a purple down jacket with red sleeves tied to her arms and a small scarf around her neck. She said that she was preparing dinner for her family.

At first, Yang Cuilian didn't resist telling her about taking salt, and her words were peaceful. However, when it was mentioned that the government added salt to the snow melting business, she became a little annoyed and raised her voice. "I'm not alone, three people will take it. If there are fifty people (look), there will be fifty people to take it, and no one will take care of it. "

After several media visits, Yang Cuilian's son thought that the media made a mountain out of a molehill. "My mother went to work in the morning and took it conveniently. Later, she was monitored and found here. That's it. "

In Meili Town, the story of "three old ladies busy with bad police in Shuli" has become a household name in Changshu. Yang Cuilian's son jokingly said, "If it snows again next year, I will be famous."

"There are so many bridges in Meili Town that it is impossible for everyone to see every bridge. First of all, some ordinary people have quality problems. How to take public property home? This time it was restored, and there was no safety accident. (But) it stands to reason that we should hold them personally responsible. " Xu Xiaoying, deputy director of DangZhengBan of the town government, expressed his dissatisfaction.

2, snowmelt salt is not edible.

Can I eat snowmelt salt?

A: Snow melting salt belongs to industrial salt. Although it looks similar to salt, its chemical composition is different. Don't take it home to eat! Once eaten by mistake, the consequences are unimaginable.

The composition of snowmelt salt is NaCl, which will dissolve when it comes into contact with snow. There is a dissolution equilibrium here. The direction of the equilibrium is that the salt is completely dissolved, so the snow is melting, providing dissolved water for the salt.

Snow melting agents are mainly divided into two categories. One is an organic snow melting agent with potassium acetate as the main component. Although this kind of snow melting agent has good snow melting effect and no corrosion damage, its price is too high, and it is generally only suitable for airports and other places. The other is chloride snow melting agent, including sodium chloride, calcium chloride, magnesium chloride, potassium chloride and so on. , commonly known as' deicing salt'. Its advantage is that it is cheap, and the price is only equivalent to110 of organic snow melting agent, but it has very serious corrosion to large public infrastructure.

Chlorine salt snow melting agent has two functions in snow removal. In addition to the endothermic effect of salt, another effect is that the freezing point of salt water is low, so it is difficult to form ice cubes after salt is dissolved in snow water, which is beneficial to snow removal.

After the snowmelt agent is dissolved in water, the ion concentration in water increases, which makes the liquid vapor pressure of water decrease, while the solid vapor pressure of ice remains unchanged. In order to reach the solid-liquid vapor pressure state of the ice-water mixture, the ice melted. This principle also explains why salt water is not easy to freeze.

3. The harm of eating pickled food

(1) increased the burden on the liver.

Due to the addition of preservatives, color enhancers and color retention agents, although these additives will not cause poisoning as long as they are not excessive, they will still increase the burden on the human liver.

(2) Increase the burden on the kidneys.

Ham and other products are mostly high-sodium foods. Eating too much will lead to excessive salt intake, affect the water balance of the body, cause blood pressure fluctuation and renal function damage.

(3) easy to ulcer and inflammation

In pickled food, vitamin C is destroyed a lot, and its ingredients are almost "gone". Therefore, if you eat a lot of pickles, it will lead to vitamin C deficiency. Lack of VC will lead to decreased resistance, causing various inflammations and ulcers. It is even easy to cause various diseases.

(4) easy to be poisoned

Pickled food is often contaminated by microorganisms during the pickling process. If the salt content is less than 15%, nitrate in vegetables can be reduced to nitrite by microorganisms, and people will be poisoned if they eat pickled products containing nitrite. Its symptoms are blue-purple skin and mucosa, blue lips and nail beds, and even dizziness, headache, accelerated heart rate and even coma.

(5) easy to stone

Pickled vegetables contain more oxalic acid and calcium. Because of its high acidity, it is not easy to form calcium oxalate in the intestine after eating, but it will be absorbed in large quantities, and calcium oxalate will crystallize and deposit in the urinary system to form stones.

(6) It is easy to cause cancer

A large number of carcinogenic nitrosamines can be produced in the curing process of food, which greatly increases the risk of malignant tumors such as nasopharyngeal carcinoma. In addition, because high concentration of salt can seriously damage gastrointestinal mucosa, people who often eat pickled food have a higher incidence of gastrointestinal inflammation and ulcer.

Pickled food can be eaten as a meal, especially when we feel that we have no appetite, we can eat some pickled food to adjust our appetite. Pickled food must use edible salt, and don't take advantage of industrial snowmelt salt. We can't eat snowmelt salt, it will kill us. Please remember not to pick up anything on the road!
