A drop of water can reflect the radiance of the sun, and it can also reveal clues in certain areas. For 63 years, under the microscope, Wang Wenxing discovered "another world" from a drop of acid rain.
From Mount Emei in Sichuan to Fenghuang Mountain in Liaoning, 271 sites were selected on the vast land, and a drop of precipitation was collected, and they were explored day after day. The old man who dedicated his life to the environment said: "When you see the dripping water, you know the sea, knowing how to see it, you can get the key to defeat the 'air demon'."
Stepping through the mountains and rivers, uncovering the secrets of hiding behind atmospheric photochemical pollution, soot-type pollution, and atmospheric acid deposition; over the years, the establishment of the Environmental Research Institute of Shandong University, the first time to introduce quantum chemistry into the environmental field. In a long and focused research career, Academician of the Chinese Academy of Engineering, Academic Advisor of the Chinese Academy of Environmental Sciences, and Wang Wenxing, a tenured professor of Shandong University, have won many “keys†to solve the pollution problem.
The 88-year-old gentleman refused to "return the armor to the field." He said: "The time left for me is not much, but I still want to do a few more things."
At the age of 57, he became a pioneer in acid rain management.
“These precipitations with a pH of very little less than 5.6 can poison tree roots, acidify water bodies, corrode metals and buildings. They are 'air devils'.â€
The old man is old, but his ambition is not diminished. He always reminds himself and reminds a new generation of researchers to defeat the acid rain.
At the age of 57, Wang Wenxing changed career. Previously, he wrote the "Industrial Catalysis" in 26 years, which was the first monograph of China in this field, and enlightened a batch of "catalytic people." But a visit to the UK in 1973 became his "catalyst" for environmental chemistry. In the old industrial country of Britain, the two industrial revolutions brought GDP, but "the clear river water was dyed gray, the white houses were smoked to gray, and the floating air was filled with gray."
Wang Wenxing said that the choice of acid rain as the research direction is because acid rain and floating dust are the most important pollution in China's air pollution at that time. China has become the third largest acid rain zone after Europe and North America.
In China in the early 1980s, the people did not understand what acid rain was, but its erosion of water bodies was intuitively reflected in the folks' "smoothing": "Irrigation in the 1970s, water quality in the 1980s, fish and shrimp in the 1990s Absolute."
To control acid rain, there is no precedent for pioneers. In 1985, Wang Wenxing took up the equipment and climbed up the beautiful Emei Mountain with his colleagues.
On the steep and steep mountain, he climbed down and explored Wang Wenxing's hope to get the "Eight Heavenly Sword" to solve the national acid rain research topic. At four different altitudes of 500 meters, 900 meters, 1914 meters and 3078 meters above sea level, repeated observations and repeated calculations, they found clues to solve the problem in a few years: in the gold dome, atmospheric chemistry, which is very higher than the atmospheric boundary layer The reaction is in a dynamic equilibrium.
It is very difficult to monitor the acid rain movement on most of China's land. The first difficulty is how to design a monitoring network in such a large area to truly reflect the acid rain situation? The second difficulty, the test of the hard environment of the mountains and rivers in the past ten years and eight years, in the field of basic research, can not be exchanged for the secular "Yan Ruyu" and "Golden House" - here to explore, only one can not see the bitter .
Since 1986, Wang Wenxing has served as the leader of the "Seventh Five-Year Plan", "Eighth Five-Year Plan" and "Ninth Five-Year Plan" Acid Rain Technology Project, leading, organizing and implementing, and personally participated in on-site observation and experimental research work, slow in the wind and rain. Slowly explore until you understand the spatial and temporal distribution of precipitation acidity and chemical composition in eastern China.
Tiandao rewards their work, and their series of achievements have become the "foundation work" for China to introduce policies and measures to deal with acid rain.
At the age of 72, he won the first national scientific and technological progress first prize in the field of environmental science and technology.
Most of the time, the city is gentle; the industry from the wind and water makes the city arrogant – factories and cars emit large amounts of SO2, NOx and VOC gases, which are converted into ozone in the air by the catalytic action of dust and sunlight. With fine particles, the original chemical chain is destroyed, forming soot-type pollution, photochemical smog and sputum.
In China in the 1980s, people were not wealthy. How to seek the maximum concentration of pollutants allowed in the air at the lowest economic cost has become the goal of Mr. and colleagues. However, atmospheric control is a large-scale project involving pollution monitoring, atmospheric chemistry, regional transmission, ecological impact, and management countermeasures, which can be dealt with alone. Wang Wenxing's strategy is to use the project as a carrier to mobilize the most professional talents in China and organize the "Joint Fleet" to tackle the problem.
"Every project, I am responsible for organizing the entire project, but also responsible for my own professional, and then from the Peking University, the Chinese Academy of Sciences and other scientific research institutions to coordinate the scientists to tackle the problem." Wang Wenxing said.
In the study of the National Sixth Five-Year Key Project “Atmospheric Environmental Capacity†undertaken by the Chinese Academy of Environmental Sciences, 25 experts from the Chinese Academy of Environmental Sciences, together with Peking University, Institute of Atmospheric Physics of the Chinese Academy of Sciences, Shanxi Provincial Environmental Protection Institute, and Shanxi Environmental Monitoring Station The "luxury team" of fifty people is invincible.
The "Joint Fleet" has been in operation for nearly 20 years and witnessed Wang Wenxing and his colleagues winning the third prize of the National Science and Technology Progress Award and the second prize until the first prize. Colleagues said that as one of the pioneers of environmental research in China, Mr.'s patriotism is included in the achievements of this country.
In 1999, Wang Wenxing and his colleagues won the first in China's environmental science and technology field, and it is also the first national scientific and technological progress first prize. Some friends remember that the award requires that the first unit of the project and the first person cannot belong to the same unit. Wang Wenxing’s choice is that “the unit must be ranked aheadâ€. "He is the first person in charge, and he chooses 'recession' in front of the highest glory. How big is this."
“The school provides him with a buffet every meal, but he is too expensive. Every day he queues up with the students to cook rice. He likes a one-dollar meal of fried bean sprouts.†Hu Jingtian from the Environmental Research Institute of Shandong University said that the school has academic research activities. Fei, Mr. does not let the use, accumulate to buy equipment. Some things allowed in the system, others "advise", but the gentleman slams "speaking": "I have a clear life, you can not let me make mistakes."
Seriously, Wang Wenxing's research results have been "opened up" and "successful" - as the largest industrial area in Asia, there has not been a large-scale acid rain hazard in Europe.
77 years old introduces quantum chemistry theory and methods into environmental chemistry
“The changes in many pollutants in the environment are difficult to study by traditional experimental methods. For example, some are very toxic and inconvenient to operate. Pure environmental chemistry is used to study environmentally harmful substances. This is a cross-cutting discipline in the environmental field. No one in the country does it, and I need to do it with young people."
After the establishment of the Environmental Research Institute of Shandong University at the age of 77, Wang Wenxing introduced quantum chemistry theory and methods into the field of environmental chemistry.
"General chemical reaction devices and photochemical smoke boxes are difficult to obtain the details of the chemical reaction primitive process, especially in the actual environmental open system, the existing technical conditions are often difficult to achieve." Wang Wenxing noticed quantum chemistry, with the new theory, The emergence of new methods, especially the development and application of supercomputers, shows great potential in quantum chemistry calculations. "It can solve the details of the traditional experimental methods 'thinking but can't do it', and can solve the problems that the former can't think of."
He invited Zhang Qingzhu, a top-notch figure in the field of environmental science, to work in conjunction with Shanda University. In the past ten years, the National Fund Committee's research report on the development of the situation of the subject of the “Chemical Decade: China and the Worldâ€, Shandong University ranked second in the field of quantum chemical density functional papers, ranking fourth in the world and fourth in the world.
Wang Wenxing, born in 1927, grew up in that turbulent and complex era. The father who had not read a lot of books taught him that "the children of poor families can only make a difference if they study, and they must make a difference." "People must know how to report, and they must be effective in serving the motherland." The bullet rain did not block his studies. He has never stopped in the face of the ideals of the scholar-officials in the world.
From industrial catalysis to environmental chemistry to education, in the three stages of life, the word “environmental protection†runs through. Wang Wenxing said that industrial catalysis has paved the way for him to enter environmental science, and education continues his "environmental dream", he can grow old, but young people grow up. Wang Wenxing believes that environmental chemistry is known through a drop of water and a smog of smoke. These young people will surely find a bigger world.
