Lin Xiaoxiao and Yang Yufeng had already seen Li Bai sampling, and this time they began to do it themselves.

According to Li Bai's guidance, the two of them gently dug out part of the coal ash from under the coal stove, put it in the sampling bag, and picked up part of the coal that had not yet burned next to the coal stove, and also put it in the sampling bag for preservation.

After sampling in the kitchen here, everyone suddenly heard Gao Meng shouting loudly in the West Wing, "Boss, come and see, there are a lot of pesticides here!"

The CDC team rushed to the West Wing and found that Gao Meng was inspecting the pile of pesticides.

There are really a lot of bottles and cans of pesticides here, and it seems that Li Jianguo usually uses to store pesticides.

The village cadres who accompanied him were also attracted to the scene, and when they saw this meeting, they explained: "Hey, there is no fuss about this, all the villagers in our Phoenix Village are tea farmers, and they have to apply medicine to the tea trees to run a tea garden, and every household has more or less pesticides, I see that many bottles here are used up, and it is estimated that Li Jianguo has not had time to throw them away." ”

Li Bai checked each medicine bottle one by one, and finally shook his head, "There are no pesticides containing arsenic, and the medicine bottles are clearly labeled, so they should be purchased from regular manufacturers." ”

Village cadre: "How dare we buy fake medicines, we usually go to a big store in the town to buy pesticides, if we buy fake medicines, then the tea trees will not suffer, and work in vain." ”

Gao Meng is in a dilemma, should these suspicious pesticides be sampled now?

Li Bai asked the village cadres, "Do you know what pesticides Li Jianguo has used in the tea garden this year?"

The village cadre took out four pesticide bottles from a pile of pesticides, "The medicine used in our village for tea gardens is basically the same, and it should be these four kinds." ”

Li Bai: "Bring these pesticides back." ”

According to Li Bai's request, Gao Meng sealed the four pesticide bottles taken out by the village cadres in a sampling bag and carefully put them into the sampling box.

Back to the bedroom where Li Jianguo and his wife usually lived, they found the medicine they often took from the drawer, and learned from the previous hospital inquiry that the couple had taken Chinese patent medicine before the onset of the disease, so the medicine in the drawer was also sampled and taken away.

After checking the homes of Li Jianguo and his wife, they went to the homes of three other patients.

The collection area is the same as before, air, water, soil, daily necessities, and every household does have a stove as the village chief said.

At the same time, another group of villagers also came out one after another, and many villagers had skin symptoms and typical rice-like arsenic boils.

The situation was reported to Li Bai.

Li Bai realized that the matter was serious, and searched in his mind for the experience of the flow just now, targeting the water source and coal.

While Li Bai was sampling, he asked the accompanying village chief, "When was the deep well in the village dug?"

"Four or five years ago, what happened?

"Not sure, do you need to take it back for testing? Have the villagers ever had skin symptoms before? For example, there is a maculopapular rash on the body, or a metallic odor in the mouth, nausea and vomiting, headache, dizziness, and fatigue, or is there any cancer?"

The village chief immediately shook his head, "No, our Phoenix Village is located on Phoenix Mountain, and you also know that Phoenix Mountain is a famous scenic spot in our county, with a good environment, good air, and the villagers are in good health, not to mention cancer, even headaches and brain fever are rare." ”

The village chief paused slightly, and added, "Since the beginning of this winter, some villagers have said that their bodies are itchy and uncomfortable, and everyone thinks that the weather is too dry this winter, and it is the first family to need to be hospitalized in such a serious condition as Li Jianguo and his wife." ”

The symptoms have just appeared this winter, so it is necessary to start looking for clues from the changing conditions this winter.

"Do you know where the coal in the village is bought from?" asked Li Bai.

"In the past, coal was pulled directly from the coal yard in the next county, and every year our village sent a car to pull it back, and the big guys shared a point. This winter, there was a hawker from out of town, and there was a truckload of coal that was very cheap and of good quality, and all the coal in the village was bought from him. ”

The change in the coal production area and the subsequent development of arsenic poisoning symptoms in the villagers made it seem suspicious that the coal was very suspicious.

"Where did that peddler get his coal from?" Li Bai continued to ask.

The village chief thought for a while, "It seems to have been pulled out of a small coal mine in Shaanxi, I don't know what the coal mine is, I heard the vendor say that his batch of coal was originally given to others, but then it was not sold for some reason, so it was sold to us cheaply." ”

It seems that the cause of arsenic poisoning in the villagers has been found this time, and nine times out of ten it is this batch of problematic coal.

Li Bai speculated that it might be that this batch of coal was found to be problematic, and the hawker was reluctant to dispose of it, so he quietly pulled it to a distant place and sold it to the villagers here.

"Do you still have the vendor's contact information?"

The village chief shook his head and said with certainty, "No, I deliberately asked him for contact information at that time, thinking that such cheap coal would be bought from him next year, but he excused himself with various excuses, saying that if he still wanted to buy coal, he would come over next autumn, so he did not leave contact information." ”

It seems that the peddler is really weak-hearted, afraid to leave his contact information to find him.

Although the clues to trace the source of the coal have been broken, as long as the coal is tested for arsenic levels exceeding the standard, the cause of the arsenic poisoning of the villagers can be determined.

The CDC team collected the hair and urine of the villagers and prepared to bring them back to the CDC laboratory for hair arsenic and urine arsenic testing.

Li Bai also suggested to the village chief that the symptomatic villagers should go to the hospital for arsenic treatment in time.

At the end of the on-site investigation in Phoenix Village, it was already 8 o'clock in the evening.

It was completely dark, there were no street lights on the mountain, and it was pitch black.

The group of disease control and control used flashlights to illuminate, stepped on the bluestone road, carried heavy sampling boxes, and touched down the mountain with one foot deep and one foot shallow.

At the foot of the mountain, two on-site shunting vehicles drove in different directions, one back to the Fenghuang County Center for Disease Control and Prevention, and the other to the Municipal Center for Disease Control and Prevention.

On the way to the Municipal Center for Disease Control and Prevention, Li Bai drove, Yu Fei sat in the co-pilot's seat, and several other members of the emergency team, as well as two interns, sat in the back rows in turn.

On the road, which is less than a few kilometers from the city, a large truck is approaching.

The road was slippery after dark, and the truck suddenly went out of control and entered the opposite lane to drive in the opposite direction.

Li Bai urgently turned the front of the car to avoid colliding with the big truck.

The truck overturned on its side into a roadside wheat field.

The on-site flow shunting vehicle hit a poplar tree on the side of the road.

The speed was too fast, the impact force was too strong, and the location of the impact happened to be the driver's seat, the front airbag was popped open, and Li Bai was knocked unconscious.

——

The First People's Hospital of Yunhai City.

When Li Bai woke up, it was already noon on the second day.

The first thing he saw when he woke up was Lin Xiaoxiao looking at him with a concerned expression.

Seeing him wake up, Lin Xiaoxiao had a smile on his face and hurriedly called the doctor.

After the doctor's examination, he instructed, "It's good to wake up, because it is a concussion, and you have to be hospitalized for a few days for observation, if there are symptoms of nausea and vomiting, notify the doctor in time, during which the family should pay attention to take care of the patient, eat lightly, and do not exercise excessively." ”

Lin Xiaoxiao nodded again and again.

She still clearly remembers the situation when the car accident occurred, Li Bai fainted on the spot, and the other people in the car were frightened, but they were all fine, and called a 120 ambulance to send Li Bai to the hospital, and several other people in the emergency team took the samples and sent them to the disease control laboratory.

Lin Xiaoxiao wanted to contact Li Bai's family, but was stopped by several people from the emergency team, and only learned that Li Bai's parents were dead, and there was only one twin brother, but this brother was an autistic patient and usually needed to be taken care of.

Li Bai is sick and hospitalized, and there will be no family to take care of him.

Fortunately, his twin brother had always had an aunt who took care of him before, and after discussing with the disease control emergency team, it was decided that several people would have time to take turns to take care of Li Bai who was hospitalized.

It's noon, and Lin Xiaoxiao happens to be in the hospital.

The first thing Li Bai cared about when he woke up was not his own condition, but how the samples were doing, and whether the samples were damaged in the car accident.

"The samples were all very good and sent to the laboratory in time, and the colleagues in the laboratory worked overtime overnight, and the test results are estimated to have come out. ”
