Although there is a color difference in the plants in the middle reaches of the Lailing River, it is not obvious.

Downstream, Jia Ru's eyes clearly saw that most plants had only three different shades of white. Especially in the farmland downstream, where the large area of color difference made Jia Ru look very uncomfortable, and she could even guess that the substances represented by these three colors were the real culprits of the pollution.

The white substance is like a fierce Qing soldier in ancient times, attacking cities and plundering land everywhere. The healthy substances in those plants became the rout of the Ming Dynasty, and they were repeatedly defeated and eventually wiped out until the plants died completely.

Further on, there are large tracts of withered farmland.

"I heard that the first whistleblowers were farmers, and it would be the harvest season after a while, but their farmland was sick and dead in large areas, which made people helpless." Deng He said on the side.

Jia Ru was silent for a moment, quietly collecting plant samples and making labels.

At the end of the day, the sun had set, and the setting sun had draped Jia Ru with a golden veil.

The last plant sample is labeled, and the girl moves her body, revealing a lazy and slender figure.

Jia Ru smiled at Deng He and said, "It's done, I'm so tired!" ”

The whole day of sample collection was hard work, but with the data from these samples, Jia Ru was confident that the real cause of the contamination could be identified.

Deng He followed the whole process, I don't know why, when Jia Ru stretched his body just now, his heart beat faster for a moment.

Dispelling the thoughts in his mind, Deng He took the equipment box in Jia Ru's hand.

"Good work."

Lunch was a boxed lunch that Deng He bought nearby, and Jia Ru wanted to express her gratitude to Deng He for dinner.

If it weren't for that plant sample, Jia Ru wouldn't have such an amazing ability.

Jia Ru, who has a good financial ability, invited Deng He to come to the more famous flavor restaurant in Lailing City, and because there were more people at dinner time, the two took advantage of the waiting time to visit the neighborhood.

However, they ran into someone who was not very willing to see.

Deng He took Rajaru's arm, pointed to the door of the luxury hotel not far away, and said, "See, old pedant." ”

Jia Ru didn't react at first, but when she looked over, she realized that it was Xu Guohui, who had just had a conflict in the morning.

Jia Ru and Xu Guohui can only be regarded as meeting in Pingshui, but the two have different concepts, but the person next to Xu Guohui is a little eye-catching.

The smooth skull looks like a light bulb in the light of the hotel lights, and his face is fierce, with a natural fierce look, and a scar on his left cheek, which can really scare crying children.

However, Jia Ru didn't pay much attention to it, and after eating with Deng He, she went back to the dormitory directly and asked Deng He to meet in the laboratory the next day.

When Deng He arrived at the lab, Jia Ru was already doing the analysis.

Jia Ru, who wore dark glasses, focused on adding a tube of reagent to the sample taken yesterday.

"Let's eat something first." Deng He put aside the breakfast he had brought.

"How?" Taking advantage of Jia Ru's eating, Deng He asked.

"I put 10 samples in a petri dish last night and tested them with different reagents, and in the morning, when I analyzed the substances in the water, I was able to confirm that the substances that caused the contamination were mercury, and I thought the other two elements that had not been concluded for the time being may be arsenic and lead."

"Mercury, arsenic, lead, isn't that the waste that printing and dyeing factories often discharge?"

Jia Ru nodded: "It's not certain yet, but eight or nine is not far from ten." ”

"Then you continue to analyze, I will first check what are the printing and dyeing factories in the middle and lower reaches of the Lailing River." Deng He said.

The middle and lower reaches of the Leyling River are neither long nor short.

However, the middle and lower part of the Leyling River is in the old town, where there are many small workshops from the seventies and eighties.

Later, after a lot of reorganization by the government, it became a factory, but due to the economic development of Lailing City, many factories fell in that area.

Even so, among the remaining factories, there are more than one or two printing and dyeing factories.

"I tested it, but it was mercury, kun, and lead." Jia Ru walked over with the report, "Moreover, the content of mercury, kun, and money and lead in the water of the Lailing River is also obviously exceeded. ”

"Well, I just checked, although it can't be 100% sure that the printing and dyeing factory is responsible, but I have also listed the relevant factories."

There are other factories that emit these three harmful substances, but printing and dyeing factories are the most likely.

There are a total of seven suspected targets, four in the midstream and three downstream.

In order to prevent emergencies, Deng He called Huang Zhaoyuan out and told him not to tell others, after all, Huang Zhaoyuan must be much stronger than Deng He and Jia Ru in terms of overt and covert visits.

Deng He and Jia Ru arrived first, and Huang Zhaoyuan also arrived not long after.

Wearing a navy blue coat, Huang Zhaoyuan got out of the car and said to Jia Ru and them: "You don't need to insist on this matter, the Environmental Protection Bureau also agrees with Professor Xu's statement and is ready to rectify the domestic sewage problem." ”

"We have found that there are serious heavy metal elements in the water." Deng He handed the inspection report to Huang Zhaoyuan.

Huang Zhaoyuan looked at the report, his brows gradually furrowed.

"Taili has decided to end this matter next Monday, if you can't find out the results before next Monday, then, whether this matter is heavy metal exceedance or not, it will be concluded according to Professor Xu's statement."

"Then why are we still stunned? GO！ GO！ GO！ Get moving. Deng He hurriedly said.

The first target was the Jintian Printing and Dyeing Factory, located in a residential area in the middle reaches of the Lailing River, and it was difficult for the printing and dyeing factories in the middle and lower reaches to influence upwards, after all, the water flowed low, so they decided to start from above.

However, what is more embarrassing is that after looking for them for a long time, they suddenly found that they were lost.

There are many tube buildings near Jintian Printing and Dyeing Factory, and the road inside is winding, and the three people walked for a long time and did not find the location of the printing and dyeing factory.

It just so happened that two women sat in front of the factory and chatted at the door, and the rusty gate and weedy ground behind them indicated that the factory was closed.

"Eldest sister, I want to ask how to go to Jintian Printing and Dyeing Factory?"

"Jintian Printing and Dyeing Factory is right in front of you, turn left, and then, turn right again......"

The process of memorizing the road was complicated, but fortunately, they eventually found the Kaneda Printing and Dyeing Factory.

There are several factories behind the gate of a small factory, and there is an old guardhouse at the door, and an uncle is on duty inside.

The uncle saw the three of them looking at the factory, looked at them with some vigilance and asked, "What are you doing?" ”

"Uncle, we're here to have a casual look, can you let us go in and have a look?" Huang Zhaoyuan asked with a smile.

"Go, go, what's there to visit in a factory?"

What they didn't expect was that the uncle would directly pick up people.

Could it be that there is really a cat in this factory?
