Chapter 234

When it comes to arsenic, we have to mention centipede grass.

It is a difficult problem for scientists to remove heavy metal pollution such as arsenic and mercury for a long time.

But later, scientists found a strange phenomenon: in some arsenic polluted land and water, most plants have died, but Centipedegrass, a fern, is safe.

After testing, the scientists found that Centipedegrass not only has a strong super adsorption capacity for arsenic, but also has a certain effect on the adsorption of other heavy metals.

After testing, centipede grass, which is rich in arsenic, is 200000 times higher than ordinary plants, and it is a plant with high arsenic tolerance.

If centipede grass is used to extract arsenic and other heavy metal pollutants from soil, and then harvest and burn, the amount of toxic waste gas will be greatly reduced, and the ash after incineration can be turned into mineral resources for smelting.

Under ideal conditions, the arsenic content in plants can be as high as 20%, which is equivalent to a mineral resource.

And as far as Zhou Wen knows, there are already scientists studying "farming metals.".

, Alan Beck, the botanist of the Melbourne University, is practicing the first mock exam.

He planted a hyperaccumulated nickel tree in a 50 acre nickel contaminated area. After cutting the bark, it would flow out a blue-green liquid, like gum. It contained 14 nickel, which was higher than the ore content of nickel smelters.

The metal is then extracted and purified for sale.

In addition, the smelter has to pay him high environmental treatment fees.

……

Zhou Wen looked at the plants which were enriched in arsenic.

The black youth followed. He pointed to the roots of several coniferous trees that he had cut off from the middle and said, "the last time I cut down these shrubs, the slurry on them was stained on my hands. It was very uncomfortable at that time. Then I went home, and soon my hands became like this."

Zhou Wen studied it carefully.

This is a shrub called "needle tree" in the local area. It is covered with sharp barbs. It is very ugly and widely grows in the rainforest.

Although it is a shrub, its root system is quite developed. It belongs to deep root plant. Its main root can be more than 5 meters underground, and some can reach 10 meters.

So, if you don't expect, there should be arsenic ore underground. Otherwise, it can't explain the area where arsenic plants grow, but other plants are not affected.

There are more than a dozen needle trees here.

Zhou Wen and his bodyguard asked for a dagger and cut the stem of the needle tree.

Needle tree: "knock you It's killing me. "

Zhou Wen: "shut up, I'm collecting samples!"

The needle tree is obviously scared, with its intelligence quotient obviously can not understand, why can primates understand its language?

At this time, it was cut on the stem, outflow of milky white liquid, "tick tock" of the fall on the ground.

Zhou Wen, while collecting samples, asked, "by the way, is there an arsenic mine underground?"

The needle tree doesn't speak.

Zhou Wen broke a branch with a click.

Needle tree: "knock you It's killing me. "

Zhou Wen: "is there an arsenic mine underground? If you don't say it again, I'll uproot you in a moment

The needle tree trembled.

Zhou Wen: "do you have any?"

Needle tree: "yes!"

Zhou Wen: "then I won't pull you out today."

After collecting the samples, Zhou Wen turned his head and asked, "where is this kind of similar plant?"

The old black man with moderate arsenic poisoning pointed to the East and said a few words. The young black translator said, "he said there are still some trees in the East. He was poisoned there."

"About how far?"

"About a mile."

Zhou Wen looked at the sky, but there was still time. He said, "let's take me there and have a look."

Black youth are lazy and unwilling to take him to see them, including those local people who are not willing to run away.

Zhou Wen said to the black youth, "you take me to have a look, and I will help you to cure it. I believe you have also gone to the hospital for treatment, this metal local poisoning is very difficult to cure, except me, no one can cure it! "

The black youth discussed with you.

These people are relatives with close ties. It is said that Zhou Wen can help young people and old people with hand diseases, and they all agree.

Zhou Wen with a security guard to follow the crowd toward the thorny woods, the rest of the people stay in place to guard the vehicles.

There was a small path that, according to the black youth who led the way, had been trodden out by South Africans who had come to their village to steal the baobabs, which belonged to the territory of bozvana.

One mile is about 1600 meters.

It took nearly an hour to get to the place in the rugged, thorny jungle.

"Here it is." Said the black youth, pointing to a dark Bush ahead.Zhou Wen stepped forward to have a look, it was really.

There are a lot of needle trees here. There are twenty or thirty by sight.

Zhou Wen collected samples from several of the thickest conifers in turn.

Of course, every time I was scolded by the tree.

Zhou Wen asked the same question to a needle tree collected at last, "is there arsenic ore underground?"

Not waiting for the needle tree to answer, he first "click" a broken branch, the pain of the needle tree squeak.

Needle tree: "why did you break my hand?"

Zhou Wen: "do you understand? I'm afraid you won't tell me, so I'll break one for you first

Needle tree: "but I was just about to tell you."

Zhou Wen: I'm sorry

The needle tree was sad for a while Zhou wenneng felt its sadness, a very obscure plant language.

Later, the oldest needle tree told Zhou Wen that there were rich arsenic minerals under its feet.

Zhou Wen thanks it and then returns.

They got out of the dense forest before the sun set.

Zhou Wen used biological antidote to help two arsenic poisoned people.

"Because this is a heavy metal poisoning, it needs a recovery period, about 6-10 days."

The black youth moved his hands and said happily, "I feel better."

Zhou Wen nodded and handed a business card in the past, "that's good! This is my business card. If you have any questions later, just call me. "

Of course, there are reasons why Zhou Wen is so enthusiastic.

The first is the hyperaccumulation of arsenic conifer, which is very rare, and its roots are still so developed that it can be called a "cash cow" whether it is used to control heavy metal pollution or to absorb underground arsenic ore.

The second is the underground arsenic mine.

Arsenic is very valuable. The market price of 6N is about 1000 yuan / kg, and that of 7n is about 2000 yuan / kg.

Of course, this will also cause great environmental pollution. If it is developed, the investment will be very large.

But it's good news.

Because of this, it is necessary to establish a good relationship with these local people in advance to facilitate some operations in the future.

After having a special local dinner, Zhou Wen and his wife rushed to the hotel in the city all night to rest.

……

……

The next morning at nine.

Lin Gaoxuan waited all afternoon and one night. Zhou Wen didn't take the initiative to come over, but Tang Wannian called.

"OK, I see..."

Lin Gaoxuan hung up the phone with a black face.

At the next moment, Shen Yujie, with peach blossom on her face and a curly hair on her mouth, asked with a smile: "how about, will he come?"

Lin Gaoxuan secretly resented: "this son of a bitch has been abroad for two months, and his brain has been damaged. No matter who's going to listen to his words."

"What can I do?" Shen asked

Lin Gaoxuan's face was overcast and uncertain for a long time. At last, he found that he had no way to take the other party except himself.

"Let him be proud for a while, and then I'll see how I deal with him when I return to China." Then Lin Gaoxuan pressed Shen Yujie's head into the quilt, took out the phone and dialed a number.

The phone was connected quickly, and Zhou Wen's voice came from inside, "Hello, who is it?"

Lin Gaoxuan sneered and said, "doctor Zhou is really a noble man. He is busy. So many people can't move you. I have to call you personally. You are very good."

Zhou Wen: "who are you?"

Lin Gaoxuan felt that his words had been said in this way. The other party could not have not known who he was. He said coldly, "you really don't know who I am?"

Zhou Wen: "nonsense ~ if you don't say it, how can I know who you are?"

Lin Gaoxuan: I'm Lin Gaoxuan. "

Zhou Wen: "no! You have the wrong number. "

"Dudu Dudu..."
