Lianhai Center for Disease Control and Prevention, Laboratory.

Lu Li and Wang Xiaoxiao were in the laboratory to test the specimens collected from Jinshan Village in the morning.

Soon, the results came in.

The well water of Li Yuanshan's house, as well as the vegetables, rice and other foods he ate at the right time, all had excessive levels of cadmium.

In particular, the cadmium content in well water was 0.624 milligrams per liter, which was significantly higher than the limit of cadmium in drinking water in China's drinking water quality and sanitation standards, which was 0.005 milligrams per liter.

The cadmium content in the water of the Jinshan River in front of Jinshan Village exceeded the standard.

Fish grown in the Jinshan River have excessive levels of cadmium.

Cadmium levels in the wastewater pond in the mine and in the pool in front of the cave where the sewage is discharged exceeded the standard.

Lu Li handed the test result report to Gu Yanan, and said to himself on the side, "Such a high cadmium content!" The villagers of Jinshan Village are literally eating batteries every day. ”

Gu Yanan looked at the report and felt that the matter was serious, so he reported the results to Director Yang of the center.

Director Yang of the Center for Disease Control and Prevention took the lead and worked with other relevant departments to deal with the public nuisance caused by environmental pollution caused by the mine.

For the next few days, Gu Yanan's emergency office was still very busy.

Because in addition to Li Jinhua, who has been diagnosed with cadmium poisoning, other villagers in Jinshan Village also have to do a census.

The relevant departments notified the villagers of Jinshan Village to go to the hospital to draw blood and urine.

Both blood and urine samples were sent to the Municipal Center for Disease Control and Prevention's laboratory.

It took more than three days for the laboratory to test all the specimens.

Of the more than 200 people, 26 were found to have excessive levels of cadmium in their bodies.

These people with excessive levels of cadmium in their bodies were all admitted to the hospital for cadmium repellent treatment.

The CDC has completed the testing task here, and the rest is carried out by other departments.

The mine near the village of Jinshan was permanently closed.

Through a friend who works in the environmental department, Gu Yanan learned that the Jinshan River, which was polluted by industrial wastewater, had begun to be treated.

Large quantities of polyaluminium chloride are injected into Jinshanhe to solidify cadmium in an ionic state to avoid absorption by the human body and other living organisms.

The land contaminated with the heavy metal cadmium has already been remediated, and they have adopted a combination of chemical and biological methods.

A large number of microorganisms that can absorb the heavy metal cadmium were released into Jinshan Village and the land around the mine.

There are also a large number of earthworms, and earthworms can also enrich cadmium in the soil, so many earthworms are also put into the land around Jinshan Village.

As for the crops grown on land with excessive cadmium, there are also options, and plants that absorb cadmium, such as spinach, tobacco, and camellia, are also planted.

Each department has its own tasks and cooperates with each other.

The Center for Disease Control and Prevention is responsible for regular follow-up of people with excessive cadmium levels.

After a period of cadmium repellent treatment, the excessive cadmium level in the villagers of Jinshan Village has improved.

A few days later, Gu Yanan and Lu Li drove the on-site shunting car to Jinshan Village to do follow-up work.

In Jinshan Village, where I went in the morning, the follow-up work did not end until the afternoon.

On the way back, Lu left the car, Gu Yanan sat in the co-pilot's seat, and the two saw villagers putting earthworms in the land on both sides of the road from time to time.

Lu Li sighed while driving, "This is the first time I have seen the use of earthworms to treat soil cadmium exceeding the standard, I have only seen it in the literature before, I didn't think that the low-level creatures that usually look inconspicuous have such a magical effect." ”

Drift trucks jolted along the dirt roads in the mountains, and some villagers worked in the fields, replacing their usual crops with sunflowers and spinach, which easily absorb cadmium metals.

Gu Yanan: "Cadmium pollution is a serious public nuisance, and all parties have been very positive in dealing with this matter, introducing new microbial communities that can absorb cadmium, lower organisms, such as earthworms, etc., and guiding villagers to change the types of crops to cultivate. ”

Lu Li sighed, "Since we had our initial cadmium test results, the work has been carried out very quickly." ”

Gu Yanan: "Since Li Jinhua's illness was determined to be a painful disease caused by cadmium poisoning, the public has been very concerned about the cause of Li Jinhua's illness. ”

Lu Li: "Yes, now the eyes of the masses are bright, they are closely watching the governance work, and they are also actively involved, you can see that the villagers on both sides of the road are busy working." ”

"Pollution is easy to control, this pollution control can not be achieved overnight, this is the land that people rely on for survival, once it is polluted, it will have to pay a great price."

Listening to Gu Yanan's tone of voice with sadness, Lu Li changed the topic and asked, "Sister Yanan, at that time, the mine owner died in the cave where the mine discharged sewage, has this case been solved?" Recently, I have been busy with the follow-up of the physical condition of the villagers, and I don't have time to gossip, you are familiar with Captain Nan, he must have the latest news to tell you. ”

Lu Li glanced at Gu Yanan expectantly.

"The case has been solved."

Gu Yanan didn't hide it, and said that Nan Hanfei had told her some information about the death case in the mine during a previous dinner, "The mine owner was killed by a vendetta, and you have seen the murderer." ”

"I've seen it?!"

Lu Li quickly reacted, and the person who had a connection with the mine owner and met Lu Li again was someone among the villagers of Jinshan Village.

"Which villager is it?"

"The one who works in the mines."

"Oh, I remembered.

When we first went to the mine for sampling, we saw a very thin man, in his twenties, and the village chief said that his family of four, two older brothers and an old mother had recently died, and he was the only one still working in the mine.

What's it called? …… Oh...... Li Yuanfeng! ”

Lu Li remembered the first time he saw Li Yuanfeng, that boy with a wooden expression and not good at words, could he be a murderer?

"Sister Yanan, why did Li Yuanfeng kill the mine owner?"

Mr. Nan said that after Mr. Li was arrested, he confessed that he believed that the deaths of his brother and mother were caused by the pollution of the mine, so Mr. Li blamed the mine owner for the death of his family.

On the day of the incident, the mine owner happened to come to the mine from the town to inspect the work.

Li Yuanfeng lied that there was a problem with the sewage pipe at the mouth of the cave, and the mine owner followed Li Yuanfeng to the cave.

At the mouth of the cave, Li Yuanfeng strangled the mine owner to death with a rope prepared in advance, and threw his body into a waterhole at the mouth of the cave.

The next day, when we went to the mine for sampling, we found the body.

After we reported the case, Nan Hanfei led the police team to investigate and found a nylon rope under the bed in Li Yuanfeng's dormitory.

After testing, the nylon rope was found to have the human cell tissue of the mine owner.

Moreover, the mine owner had scratched Li Yuanfeng's arm before he died, and Li Yuanfeng's dander tissue was found in the mine owner's fingernails.

In front of the evidence, Li Yuanfeng quickly explained the crime. ”

Lu Li sighed, "If the cadmium pollution in the mine had been discovered earlier, the tragedy of Li Yuanfeng, Li Jinhua, and Jinshan Village might not have happened." ”

"It's not too late to make amends, but that's the price...... Some are big. ”
