Pangguofang, a researcher of the Institute of flam

On March 7, 2014, AOAC official website news: on March 7, 2013 (Gaithersburg, Maryland), the International Association of Analytical Chemists (AOAC International) awarded the 2014 Harvey W. Wiley award to researcher pangguofang in recognition of his outstanding contributions in the field of analytical chemistry. Researcher pangguofang will accept the award at the opening ceremony of the 128th international AOAC annual conference and Expo, the highest scientific honor award of AOAC, and will deliver an award-winning speech at the Harvey Willie award seminar. The 128th international AOAC annual conference and Expo will be held in Boca Raton, Florida, from September 7 to 10, 2014

researcher pangguofang is now a researcher of the China Academy of inspection and quarantine sciences. This award not only reflects the high recognition of international AOAC for his outstanding academic achievements, but also for China's contribution to the research and application of AOAC methods. Since 1985, he has been working in the field of agricultural products and food inspection for 30 years, paying special attention to the research on pesticide and veterinary drug residues. He led the research and established a testing system to help Chinese honey, chicken and brown rice enter the global market. He also organized and led the collaborative research of international AOAC and established two international AOAC methods. Recently, he is developing a method of gas chromatography quadrupole time of flight mass spectrometry and liquid chromatography quadrupole time of flight mass spectrometry for one-time sample preparation and simultaneous detection of 1138 pesticide residues and other pollutants in fruit and vegetable samples

the leading achievements of researcher pangguofang include:

the development of international AOAC method - Simultaneous Determination of pyrethroids in agricultural products by gas chromatography (official methodsm 998.01)

developed the international AOAC method - liquid chromatography for monitoring chlorhydroxypyridine veterinary drug residues in chicken (official methodsm 2003.04)

developed more than 300 methods for the determination of pesticide residues in Chinese honey, including the use of stable carbon isotope methods to prove that "Chinese" Honey actually comes from Chinese pollen

China has developed the first high-throughput method in a series of chromatography-mass spectrometry techniques for more than 1000 pesticide residues in agricultural products

30 international laboratories in 11 countries and regions were organized to participate in the collaborative research of international AOAC, and the high-throughput analysis technology of 653 pesticide residues in tea was developed

in addition, he has published 10 Monographs on food safety science and technology at home and abroad, and published more than 100 papers

researcher pangguofang won the international AOAC fellow in 2007, the international AOAC Cooperative Research Award, the international AOAC Deputy arbitration award and the international AOAC research mentor award issued by the international AOAC organization in 1998 and 2003, and the 2013 AOAC ERP evaluation expert award. Since 1994, he has become a member of AOAC

the annual Harvey Willie award is the most prestigious scientific honor award of the international AOAC, in recognition of scientists who have made outstanding contributions to promoting analytical methods and technologies. The award was established in 1956 to commemorate Harvey W. Wiley, the founder of the international AOAC and known as the "father of the pure food and drug law" (October 30, 1844 June 30, 1930). Academician pangguofang is the 58th scientist to win the award since the establishment of the award, and also the first Chinese scholar to win the award

an extraordinary career begins with hard work

pangguofang is the son of a Chinese farmer who grew up in the 1940s and 1950s. He became the first student in the village to enter a middle school (equivalent to a high school in the United States), and had not even seen an electric light before. More than 50 years later, he presided over the research of a series of detection technologies, so that China's honey, chicken and brown rice were recognized in the international market. At the same time, he successfully organized three AOAC collaborative studies, and the three technologies were developed into AOAC public methods. Recently, gas chromatography quadrupole time-of-flight mass spectrometry and liquid chromatography quadrupole time-of-flight mass spectrometry have been developed to prepare fruit and vegetable samples at one time and simultaneously determine up to 1138 kinds of pesticide residues and other pollutants made of alloy steel

pangguofang's life is not a smooth road. His extraordinary career began with hard work, his mother's life teaching, and he admitted that he was once one of the students with the worst grades

at the age of 11, he just finished the fourth grade of primary school. At that time, he was divided into elementary school and high primary school in China. He said through an interpreter that the school will publish the examination results of all grade students from high to low in the wall newspaper column, and the last one will also be marked with a big red hook drawn with a brush. He said: the students jokingly called it "carrying the Red List"

that year, on the day of the announcement of the list, he found that he had "carried the Red List". "I feel my face is hot, my heart is pounding, and I sweat a lot. This is the first time in my life that I know what shyness is.". Although his score was at the bottom, he was allowed to be promoted to high school. He said, "I'm still lucky."

after he was promoted to high school, a teacher named Gao Fengxing began to teach him. The teacher's teaching style pays attention to practical application, so it inspires the imagination of the 11-year-old child. Pang said, "since then, my academic performance has been different from that in the past."

at the same time, rural life is still dominated by agricultural work. During the autumn harvest, the school has a three week holiday, and students of all ages go to the fields to help work. When adults harvest crops, Pang's main task is to pick up the straws thrown in the fields and use them to make a fire to cook and heat the "Kang" to keep warm in the winter

at first, it was just a farm job for pangguofang, but later, he got up earlier and earlier, so that he could pick up more straw for his family. At the end of the holiday, that is, the key year when he had a new teacher and cultivated an increasingly mature professional ethics, he picked up so much straw that he had enough to cook in the winter. His parents said, "we've had a good winter."

another lesson he learned from his mother is to keep old exercise books instead of throwing them away like a bear breaking a stick. He said that by doing so, we can review the old and know the new and see our own progress

he said that there was a famous saying in ancient China: "take yourself as a mirror, you can know your merits and demerits", which can promote your academic progress

in 1957, pangguofang was admitted to junior high school and became the first middle school student g in the village. In order to go to middle school, he came to a small town 20 kilometers away from home. There, he once again showed a strong character. One cold winter, one of his tasks was to replace the blackboard newspaper written in chalk regularly. The task was time-consuming and lengthy. His hands were too cold to hold the chalk, so he had to take turns writing with another classmate. His hand was frostbitten twice, but he was like a good one and never delayed

at the same time, when he graduated from junior high school in 1961, one of his compositions was selected as the best composition in nine graduating classes (about 500 people). A poem he wrote was also published in a local magazine. He said: at that time, my classmates gave me a nickname "little writer", and I also dreamed of becoming a writer one day

but when he graduated from high school in 1963, his brother, who was ten years older than him (as a manager in a chemical plant), persuaded him to reconsider whether to study science and engineering. At that time, Pang had never seen a chemical plant and had little chance to do chemical experiments, but he finally accepted his brother's advice. He said: I filled in the "chemistry department" in my application for college entrance examination

it was by no means easy to go to college at that time. In 1963, pangguofang graduated from four classes with 200 students, and only 16 of them were admitted to the University. At that time, a teaching director and a physical education teacher of the school rode a 20 kilometer bike and personally sent the admission notice to his home. Pang said, "our whole family is extremely happy.". He became the second college student in the history of the village

pangguofang was admitted to Hebei University, which was located in Tianjin, the third largest city in China at that time. Going to Tianjin itself is an unusual journey: first, walk 4 kilometers, then take a two-hour bus, and finally get on the train for the first time and drive to "a world full of novelty", which is the academic home of most of his life

the novel world began with a visit to a synthetic fiber factory. The budding chemist watched the nylon filament (a Chinese synthetic fiber) sprayed from the nozzle. Pangguofang said, "in the past, I only knew that the clothes we wore were all home grown cotton. My mother spun cotton into cloth and then made clothes. It was amazing to see such novel chemical weaving materials." This is his first personal experience of the field he chose for his development direction

it took pangguofang 19 years to realize the call of duty he felt at the import and export commodity inspection bureau that year. During this period, he spent two years in the countryside in the late Cultural Revolution, then transferred back to the university to teach organic chemistry, and participated in the development of train brake shoes and automobile brake pads. He also taught himself (written) English and began to translate the English version of physical chemistry into Chinese

at the same time, as he began to design innovative scientific research tasks for graduate students, "teaching and learning grow together" gradually became his motto. He directed several graduation projects, but the graduation project that changed his life was related to food hygiene

in 1980, after many investigations, he learned that the export of some Chinese agricultural products encountered resistance because some health projects were unqualified. He said, "for example, hairy crabs in China were rejected abroad because of excessive arsenic.". Therefore, he decided to choose this question as the topic of his graduation thesis. When designing the project for students, he did not choose the general atomic absorption technology and ultraviolet spectroscopy technology, but chose a new micro coulometric titration technology developed under his auspices, which made a new breakthrough in students' graduation thesis and also highlighted Pang's personal understanding of "teaching and learning grow together"

pangguofang noticed that teachers can't predict the final results of students' research, and some designs sometimes go well and sometimes don't. He said, "if the project is not carried out smoothly, students often ask a series of questions about the teacher's project design. At this time, it is particularly necessary for the teacher to have deep background information about the design plan. To be good at opening new ideas from the students' problems, it is particularly necessary to find a new way". He said that we must have an open mind to these problems of students, rather than defending the original design everywhere. In this way, we can "lead the subject research into depth from another angle, rather than being blinded by difficulties and problems, so that we are helpless"
