Laboratory Building, School of Chemical Engineering.

A key laboratory.

The lab was in chaos.

Because I just moved from the old yard, I didn't have time to tidy up a lot of things, so it looked very messy.

Before the police could ask first, one of the accompanying leaders of the university asked, "Dean Zhang, who commanded the relocation of your laboratory?" It's been more than a week since I first moved, why is it still so messy in the lab? ”

Dean Zhang looked nervous, "Because two new returnees have been recruited in the hospital this year, the use of the laboratory is still being discussed in the hospital, so some things have not yet had time to be sorted out." ”

"When is this still being discussed? Hurry up and get your lab in order and see if you've lost anything, especially important hazardous items! ”

Gu Yanan thought to himself, the management of this chemical engineering college is really chaotic, and it is not strange to lose two packets of thallium salt.

Nan Hanfei communicated with the leaders of the hospital, "Try to check the items related to thallium metal first. ”

Dean Zhang promised again and again, "Okay, well, only Professor Li can use thallium metal in our Institute of Chemical Technology, but he went to the field to attend an academic conference in the past two days, and I asked his teaching assistant and the graduate students he brought to come and sort it out." ”

Soon, several young people who looked like students rushed over.

The young man at the head asked Dean Zhang, "Dean, can we enter the laboratory now?" ”

Dean Zhang was a little impatient, "Why didn't the people in your group come to tidy up the laboratory earlier?" ”

The young man looked stunned, and with a puzzled tone, "I wasn't allowed to come in before, the logistics said that the laboratory had not been allocated yet, and the keys were not given, and after the movers put things in, the door was locked, and our group's experiments were stopped for more than a week." I have reported this situation to you, the dean, and you also said that you will wait until Professor Li comes back to make a decision. ”

The faces of Dean Zhang and several school leaders were embarrassed and ugly.

Dean Zhang urged, "Don't talk about it yet, go and sort it out first, you must have a list when your laboratory moves, and correspond one by one, to see if there is anything missing, especially related to thallium metal." ”

Several graduate students and teaching assistants began to take inventory.

The others couldn't help, and they didn't dare to go up and help.

The bottles and cans on the table look like ordinary salt, but I don't know which bottle and bag are highly toxic.

During the inventory, a hospital leader looked at Gu Yanan and his party from CDC, and then cautiously asked, "This matter is also under the control of your CDC?" ”

"This thallium poisoning incident is serious, and our Municipal Center for Disease Control and Prevention is one of the member units of the emergency response team of the entire incident, responsible for the sampling and flow control of patients, suspected patients and suspected contacts."

"Sampling? Do you want to have blood sampling? Who are you going to take? ”

"The staff who are responsible for the relocation of the laboratory of the School of Chemical Engineering this time, as well as the teachers and students who may be exposed to thallium salt, because there is an incubation period from the ingestion of thallium salt to the manifestation of symptoms, as long as it is possible to be exposed, it is within the scope of our sampling flow control."

"This is easy to do, I'll help you gather people. Where do you want to collect blood from teachers and students? Is it okay to have a classroom? ”

"There's an open-air plaza in front of the experimental building, and there's a makeshift medical tent for CDC workers there."

"Okay, I'll do it right away."

Acting separately, the disease control staff took samples from teachers and students and asked questions about the flow survey.

Nan Hanfei led the police team to stare at the laboratory and count the experimental items.

Soon, the results were counted.

Professor Li's teaching assistant reported with a dark face and a trembling voice, "There are two packets of thallium salt missing, 500 grams each." ”

The source of the poisoning was finally identified.

——

A few days later.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan is writing a summary report on the thallium poisoning outbreak.

The School of Chemical Engineering of Lianhai University moved to a new campus, and asked the moving company to transport the laboratory items.

During transportation, the truck overturned, leaving two bags of thallium salt in the grass at the scene of the accident.

The old man picked up thallium salt and brought it back to his temporary residence in the back alley of the commercial street on Esplanade.

Li Ming, an employee of Lianhai Tu Restaurant, went to the old man's shack to look for the lost sausage, and mistakenly took two packets of thallium salt back to the restaurant as table salt and placed them next to the salt jar.

Chef Wong poured one packet of thallium salt into the salt jar, and the other packet of thallium salt into the cabinet where the salt was stored.

Cooking dishes with thallium salt, the staff and customers of the local restaurant have developed gastrointestinal, nervous system, and hair loss symptoms one after another.

On the surface of the thallium salt bag found in the salt storage cabinet of the local restaurant, the fingerprints of the restaurant staff Li Ming and Wang Dawei, the old man who picked up waste and Professor Li's assistant teacher of the School of Chemical Engineering were found.

After laboratory testing by the Municipal Center for Disease Control and Prevention, a total of 87 patients were found to have excessive thallium content in their bodies.

All patients were caused by the consumption of thallium-contaminated dishes from Lianhai Tu Restaurant.

There was no excessive thallium content in the body among the teachers and students of the School of Chemical Engineering of Lianhai University.

The hospitalized patients were discharged after Prussian blue detoxification treatment.

After writing the summary report, Gu Yanan filed the report.

Wang Xiaoxiao sighed: "Today is the last case of patient discharge, this thallium poisoning epidemic is finally over." ”

Gu Yanan: "In this matter, our disease control work is over, but the rehabilitation treatment of some patients has just begun. ”

"Huh? Wasn't it the last patient to be discharged? Wang smiled and asked.

Zhou Lao replied: "The follow-up of the patient is me and Gao Fei are following up. The last patient to be discharged today is Wang Dawei, the chef of Lianhai Tu Restaurant, although he was discharged, but it is not a cure, because when he is cooking, he is used to tasting the taste before coming out of the pot, so he ingests the most thallium salt, although the special antidote Prussian blue is used, but thallium has caused serious damage in the body, leaving sequelae of the nervous system. He was transferred to a specialized rehabilitation hospital, and the rehabilitation process would be lengthy. ”

Gao Fei sighed: "Li Ming, the waiter in the restaurant, was discharged from the hospital a few days earlier, and he was also transferred to a rehabilitation institution to continue his recovery, and his condition was not good, probably because he ate more working meals in the restaurant in those days, and the thallium content in his body was higher than that of other employees, and the doctor said that his intelligence would be affected later." ”

Lu Li: "What about the others." ”

Gao Fei: "Customers have basically only ingested once, the detoxification effect is good, there will be no sequelae, although the other people in the restaurant are in serious condition, but the chance of leaving sequelae is not large." Only chef Wang Dawei and waiter Li Ming are more serious. ”

Wang smiled: "Hey, flying is causing trouble." ”

Gu Yanan: "This is a man-made disaster!" If the School of Chemical Engineering strengthens supervision during the moving process, if the scene of the car accident can be cleaned up, if the old man who picks up waste knows the chemical label on the yellow plastic bag, if Li Ming does not arbitrarily frame the old man who scavenges for stealing salt, if the chef of the restaurant can identify the salt of unknown origin, then everything may be different. ”

——

Weekend evenings.

Xinhua Apartment.

Gu Yanan's residence.

Cousin Li Xinran took advantage of the weekend to come over to eat.

Gu Yanan personally cooked a few dishes.

At the dinner table, Li Xinran asked, "Sister, where is my prospective brother-in-law?" Why don't you call him to come along? He lives next door. ”

"He's on a business trip and he's not here these days. Also, don't call people around. ”

"Oh, I don't understand the world of you adults. However, sister, I have a big deal for you. Li Xinran began to gossip about the school again, "Our school has changed leaders, and there have been several changes. ”

"Oh?" Gu Yanan squeaked, expressing interest in continuing to listen.

"It's you and your brother-in-law...... Brother Nan, the last time I came to our new campus to investigate, several school leaders have been punished recently. ”

"Hmm."

"Sister, aren't you surprised?"

"Expected."
