Veteran new police officer

Monday, go to work normally.

Xu Haoran rushed to the unit, only to find that the office was empty.

Not to mention Han Keng being late, it was normal even if he didn't come, but it was impossible for Hou Wen not to go to work on time.

He felt very strange, so he walked diagonally across and knocked on the door of the general room: "Sister Jiang, where are Captain Han and Hou Wen?"

"They went to Xingdong with Xiao Zhi, didn't you know?"

"The Korean team didn't tell me, why didn't they take me with them to Xingdong!"

Sister Jiang neither wanted to care nor had the energy to care about the intelligence squadron, so she muttered: "Why don't you call and ask if they have just left."

"Okay, I'll call and ask."

The feeling of being "abandoned" was unpleasant. Xu Haoran felt depressed and returned to the office to dial Han Xin's cell phone.

Unexpectedly, as soon as she spoke, Han Xin handed the phone to Xiao Zhi. She only heard Xiao Zhi say on the phone: "Xiao Xu, we only found out through big data analysis that Jiang Zhengfei's activities in Xingdong are relatively frequent. There is no evidence that he He was engaged in drug trafficking activities in Xingdong, and everything he said before is all speculation."

"Xiao Zhi..."

"Don't worry, listen to me. There are only three people in your squadron. You can't let Jiang Zhengfei affect your normal work.

Your current task is to develop informants, broaden our sources of intelligence clues in the urban area, and strive to become smart as soon as possible. Do you understand? "

"Yes, understand."

He was thrown away just like that!

Xu Haoran felt very uncomfortable and couldn't ask any more questions. He could only follow the original work plan and make friends with the online ride-hailing driver, courier boy and takeaway boy.

In fact, Xiao Yunbo did not go directly to Xingdong, but took Han Xin and Hou Wen to the Binjiang Municipal Ecological Environment Bureau first.

Institutional reform has created many new government departments, and the Bureau of Ecology and Environment is one of them.

The Bureau of Ecology and Environment is not the original Environmental Protection Bureau that has changed its brand as the public thinks.

In addition to the functions of the former Environmental Protection Bureau, it is also responsible for the original work of the National Development and Reform Commission in response to climate change and emission reduction, and the supervision of the former Municipal Land and Resources Bureau to prevent groundwater pollution.

In addition, the former Municipal Water Affairs Bureau was responsible for the preparation of water functional zoning, the management of sewage outlet installation, and the protection of river basin water environment. The former Municipal Agricultural Committee was responsible for the supervision and guidance of agricultural non-point source pollution control and other responsibilities.

The Bureau of Ecology and Environment has an ecological monitoring center with advanced instruments and professional staff.

Considering that the bureau's funds are relatively tight, and the Ecological Environment Bureau is a member of the Narcotics Control Committee, Xiao Yunbo, with the support of the city leaders, reached a cooperation agreement on "sewage poison testing" with the Ecological Environment Bureau.

The Bureau of Ecology and Environment not only arranged dedicated personnel for docking, but even transferred three engineers from the Ecological Monitoring Center to form a technical research team to study how to conduct sewage drug detection.

Accompanied by a deputy director of the Bureau of Ecology and Environment, the three people put on white coats, non-woven hats, and shoe covers, and walked into a laboratory that looked very high-tech.

"Wang Gong, Xiao Zhi is here. Please introduce him."

"Okay, leaders, please look here."

Wang Gong adjusted his eye mask and picked up a cup of sewage from the operating table, which he didn't know whether it was purified or concentrated, and he spoke with all his treasures:

“We have researched and found that it is not difficult to detect drugs in sewage. Using solid-phase extraction, liquid chromatography, and mass spectrometry technology, drugs can be revealed at the molecular level.

For example, this bottle of sewage undergoes a series of pre-treatments such as filtration and extraction, and is analyzed by instruments. Combined with water quality parameters and the surrounding environment, it is possible to analyze whether the water contains drugs! "

This work is important…

It is said that some provinces have begun to use sewage testing to check the drug situation in various places, and even use this as a basis to evaluate the work of local anti-drug departments.

The Criminal Technology Center does not have this condition and can only ask qualified units for help.

Xiao Zhixiao asked: "Wang Gong, does the monitoring center have testing equipment for this?"

"The technology and equipment are fine, but if you want to put it into actual combat, there are still many factors to consider."

"What factors?"

“To ultimately determine whether there are drugs in the sewage and how much, we need to compare and have a reference.

We can now only use the drug standard spectrum library produced by international high-purity drug standards and compare it through mass spectrometry signals. "

Xiao Zhi didn’t know much about technology. In fact, the entire detachment didn’t have talents in this area. He asked thoughtfully:

"Wang Gong, are you worried that the results of the comparison based on international standards are different from the results we need?"

"It can be understood that way. After all, testing is nothing else. There must be a standard."

"In fact, although this work is very important, for us it is mainly to monitor the drug situation, which means we should be aware of it.

The test results and related data are different from the test results of testing institutions such as the Criminal Technology Center. It can be said that they are only used for reference and will not be used as evidence. "

Wang Gong asked with a smile: "Is it just about right?"

This is "black technology". Not only have I never been exposed to it before, but my superiors don't even have a standard for this aspect.

Xiao Zhi said with a bit of embarrassment: "It's not a big difference, as long as it can be detected. We can first conduct a large-scale sampling test, such as sampling from several large-scale sewage treatment plants.

If drugs are detected in the sewage, we will narrow the scope and trace the source step by step to a certain community or even a certain district. Then we can conduct targeted investigations. "

It turns out that the police don’t care about data, they just want to know whether anyone is taking drugs in a certain area...

Gong Wang originally wanted to discuss technology with them, but found that they didn't understand anything. He was a little disappointed. He put down his cup and said:

"Even if we don't have high requirements for the data, we still need to conduct a test first and correct the measured data based on the living habits and environment of the people in each area. There must be a baseline data."

"No problem, you are an expert on how to test, we listen to you."

"There is another factor to consider, such as morphine, which is used in many hospitals. I may have to conduct repeated experiments to find out how much difference there is between the drug components metabolized by the human body and those directly thrown into the sewer. "

Wang Gong thought about it and said: "In the process from sewer to sewage treatment plant, there is a metabolic process. These need to be corrected through post-processing data to distinguish some subtle differences."

Han Xin admired a capable person like Wang Gong, but she really didn’t have time to listen to what he had to say. She couldn’t help but ask: “Wang Gong, how many types of drugs can you and your team detect through sewage?”

"Heroin, methamphetamine, ketamine, morphine...as long as they are drugs, existing technology can detect them."

"That's great. As long as you can detect it and trace it back to three or four levels, I guess I can pinpoint the source of the poison."

By assisting the Anti-Drug Office in this work, the Bureau of Ecology and Environment will definitely win back a brand as an advanced anti-drug unit next year!

Deputy Director Gu of the Ecological Environment Bureau knew that Wang Gong, a technical geek, was not very sophisticated, so he turned around and asked with a smile: "Xiao Zhi, where do you plan to start testing?"

"We are going to start from Xingdong."

"Use Xingdong as a pilot?"

"Yeah, but this needs to be kept secret."

"Don't worry, we have to monitor the city's sewage. We have many monitoring stations and monitoring points."

"Then let's decide on a testing plan first."

"No problem, Mr. Wang, this is not the place to talk. Let's go to the conference room together."

There are priorities.

Large-scale testing and drawing a city-wide sewage drug detection drug map is a long-term task, and the drug situation is constantly changing and requires constant monitoring.

The top priority is to find out whether there are hidden drug addicts in Xingdong and whether there is really a drug trafficking network!

Han Xin followed everyone into the conference room of the monitoring center, took out a map of Jiang Zhengfei's activities in Xingdong analyzed by big data from her bag, and handed it to Wang Gong at Xiao Zhi's signal.

"Wang Gong, we plan to test these six places first."

"Detection is not difficult, but we must first understand the situation of the sewage pipe network."

"The Xingdong Public Security Bureau doesn't understand these things. Can it ask the Xingdong Ecological Environment Bureau for assistance in the name of random inspections?"

"Xiao Zhi, are you saying you won't come forward?"

"We don't know the technology, so we can't help even if we come forward, but Xiao Han and Xiao Hou will participate."

Deputy Director Gu realized that this was a confidential operation, and the Xingdong Public Security Bureau might have been kept in the dark. He couldn't help laughing and said: "No problem, I will arrange it for the Xingdong Ecological Environment Bureau. I will send a notice later to inspect and supervise the operation." You can check everything.”

Xiao Zhi smiled and said: "Thank you very much. I'll trouble you two now."

"Let's not talk about trouble. We are originally a member of the Narcotics Control Committee. We have no choice but to do so. Since we have this condition, of course we must make some contribution to the anti-drug campaign."

Deputy Director Gu smiled and then changed the topic: "Wang Gong, good job on this job, our Ecological Environment Bureau will definitely be an advanced anti-drug unit next year, and you may be able to name an advanced individual in anti-drug control!"

It doesn't matter what the anti-drug detachment wants. The only thing it can give others is honor.

How could Xiao Zhi fail to hear the implication of Deputy Director Gu's words? He immediately knocked on the table: "If this job is done well, it will be more meaningful than solving ten drug cases. Not to mention advanced individuals in drug control, even the most beautiful anti-drug people have hope."

"Wang Gong, did you hear that? It's the most beautiful, hahaha."

"My image is sorry for the audience, but it is the most beautiful. Guju, Xiao Zhi, since we have determined the scope of testing first, how about we go to Xingdong first?"

"Wang Gong, I'm sorry, I have a meeting in the morning... How about I ask Xiao Han and Xiao Hou to accompany you."

"Sampling is nothing else. You don't need to do it yourself."

After negotiating with the Ecological Environment Bureau, we will set off immediately after Wang Gong packs up the equipment for extracting sewage.

Next, we have to deal with them for a long time. After all, the whole city needs to be tested. Han Xin chats with Wang Gong while driving, getting close to them and making friends.

Hou Wen couldn't say anything, but he was very excited.

Returning to the old unit, if the problem is really detected through this "black technology", and the detection scope is narrowed layer by layer, and finally traced back to the source of the drug, and hidden drug addicts and even drug dealers are targeted, then the expressions of the leaders of the old unit will be certain when they find out. It will be exciting...
