Using treated plant waste as a filter reduced the presence of harmful microplastics in agricultural runoff by more than 92%, according to a new study authored by a University of Mississippi research team.

Microplastics – tiny plastic particles that are smaller than 5 millimeters – have been found in every ocean on earth, in food, water, and recently, in farmlands. An Ole Miss-led research group has published proof-of-concept data that shows biochar to be a cost friendly and effective method of filtering microplastics from overland water runoff.

Biochar is a type of charcoal made from plant material that has been heated or burned in an oxygen-limited environment.

“Microplastics in the environment stem in part from the degradation of larger plastic by natural physical, chemical and biological processes,” said James Cizdziel, professor and interim chair of the Department of Chemistry and Biochemistry.

“They pose an enormous challenge as they are widespread, persistent and can accumulate in plants and wildlife, leading to detrimental effects on certain organisms and, potentially, on humans who consume them.”

Microplastics have been found in humans and the part of human brains responsible for smell. Though scientists don’t yet know the effects of microplastics on the human body, many studies show that the plastics negatively affect fish and animals that ingest them.

Microplastics in agriculture come from two primary sources, said Boluwatife Olubusoye, an Ole Miss doctoral student in chemistry and an author of the study. Sewage sludge from wastewater treatment plants, which is used as a fertilizer, and plastic mulch and row covers, which insulate plants and promote growth, both bring measurable amounts of microplastics to agricultural areas.

“When these plastic sheets break down in the field, they become very tiny and that’s how you get microplastics in the agricultural fields,” the Lagos, Nigeria, native said. “What happens is that when there is a heavy rainfall, there will be a wash of this agricultural field, which can lead to agricultural runoff.

“And this runoff can transport microplastics, and other pollutants, from the farm into aquatic environments – such as rivers, lakes and oceans – where microplastics can pose threats to organisms like oysters and small fishes.”

Many animals, including humans, feed on such organisms, where the microplastics could be passed on.

Olubusoye and collaborators from the U.S. Department of Agriculture’s Water Quality and Ecology Research Unit in Oxford traveled to a farm near Beasley Lake in the Mississippi Delta to collect agricultural runoff.

They tested the water for microplastics in Cizdziel’s microplastic research laboratory at Ole Miss, and passed the runoff through biochar to determine how effective it was at capturing the microplastics.

“We also observed that in addition to agricultural runoff, urban stormwater runoff is a prominent source of microplastics pollution,” Olubusoye said. “Our research is trying to reduce the influx of these contaminants from these runoff events into downstream water bodies.”

Using biochar reduced the amount of microplastics in samples of runoff by between 86.6% and 92.6%. Because of the success of the initial tests, the researchers are scaling up efforts to test biochar in the field.

The researchers will present their findings at three upcoming conferences, including:

“Our findings underscore the potential of biochar to be a cost-effective adsorbent for the removal of microplastics from runoff,” Cizdziel said. “As such, scaled-up field studies are underway and preliminary data show a marked decrease in microplastics, including tire wear particles, after the runoff passes through large filter socks filled with biochar.

“Our work could result in new agricultural and stormwater management practices to mitigate microplastic pollution stemming from farms and urban runoff in order to safeguard environmental and human health.”

Chemistry Department Remembers Beloved Professor Kwang Yun

Posted on: April 7th, 2022 by nhammer

Kwang S. Yun (1929-2022), an award-winning chemistry professor who taught at UM for 30 years, was known for his creative teaching methods and dedication to students.  He received  the Cora Lee Graham Outstanding Teacher of Freshmen award from the College of Liberal Arts, the 1981 Outstanding Teacher of the Year Award for the University (now known as the Elsie M. Hood Award), and the Phi Eta Sigma Honor Society’s Outstanding Teacher Award.  Prof. Kwang Yun joined the Department of Chemistry in 1968 and taught general chemistry, physical chemistry, and graduate courses in quantum chemistry and statistical thermodynamics for 31 years. He was loved by his students and retired in June 1998, but still participated in physical chemistry divisional activities up until 2020.

Prof. Emeritus Kwang S. Yun (1929-2022)

Prof. Emeritus Kwang S. Yun (1929-2022)

Originally from Seoul, Korea, Yun received a B.A. in chemistry from Seoul National University before serving in the Republic of Korea Army from 1953 to 1955 and earning a Ph.D. in chemistry from the University of Cincinnati in 1960.   “I had the great pleasure of teaching the freshman chemistry course,” Yun said. “Students in this class were mostly pre-med, pre-pharmacy or engineering students who were well motivated and eager to learn new and advanced concepts in chemistry. For more than 30 years of teaching this course, I have nothing but good memories.” 

Prof. Emeritus Kwang S. Yun (1929-2022)

Yun had several memorable moments from the classroom.  “I gave weekly live demonstrations related to the subjects of the week,” he said. “Students enjoyed  the demonstrations, but I had a few embarrassing moments with burning hair, burning neckties, falling from ladders and so on.”

The effectiveness of Yun’s teaching is evident.  “More than 6,000 students passed through my freshman classes during my years of teaching, which generated many well-known doctors and pharmacists,” Yun said a few years ago. “I see them often.”

“When I was an undergraduate chemistry student, he was the first chemistry professor I took that made sense,”  Associate Dean Emeritus for Research & Graduate Education and Distinguished Professor Emeritus Charles Hussey said. “He knew how to teach. When I was in his class, I was always very comfortable — he explained concepts like no one else.”

It was indeed a high priority for Yun to successfully convey the material that he was teaching.  “I held weekly help sessions and enjoyed the recitations because it was a ‘free question-and-answer period’ where students felt comfortable asking any questions,” he said. “Because my main interest in teaching was to provide students knowledge and excitement in science, I always approached students not in terms of my level of understanding but at the student’s level. I used to say to myself, ‘If a student does not comprehend an idea, it is my fault and not the student’s.’”  Prof. Randy Wadkins had Yun as a teacher while he was at Ole Miss as an undergraduate and a graduate student.  Wadkins recently indicated that “What might not be appreciated is that Dr. Yun also taught math. I kept all the notes from his class all these years.”  It is evident Dr. Yun holds a special place in the hearts of his former students and was well respected by his colleagues. He taught chemistry and helped many students prepare to pursue their careers in medicine, pharmacy, science, and other fields. He was a favorite teacher because he really cared about his students and was always willing to help them succeed.

Prof. Dan Mattern was a colleague of Yun for a number of years in the department.  Mattern recently said “I too am saddened by the loss of Kwang, who was always upbeat, enthusiastic, and smiling. He was also very precise in his teaching of chemistry, and his classes appreciated his careful explanations, and his consideration for his students. After he retired, he took up oil painting, with landscapes and scenes around Oxford–quite a switch from physical chemistry. A couple of years ago, he told me about his schooling under the Japanese occupation of Korea. All the instruction was in Japanese, and the teachers were rigid, but not mean. One day he went to school, and the entire teaching staff was gone. Japan had withdrawn from Korea, and that included leaving the schools, overnight. I’m always impressed with people who have to switch languages when they immigrate. Kwang had to switch from Korean to Japanese, and then to  English.  We will miss him.”

Long after his official retirement from the University in 1998, Yun continued to come to campus and check out books from the library to read.  Prof. Nathan Hammer shared that Dr. Yun also continued to perform spectroscopy experiments alongside undergraduate and graduate students in his lab up until just a few years ago.  Hammer said “Prof. Yun loved science and being in the lab.  He gave lectures to our Summer Research Experience for Undergraduates (REU) program on classical physical chemistry concepts and really enjoyed attending physical chemistry division social event.  The students loved learning from his lifelong experiences and always looked forward to him bringing watermelons to our end of summer REU party.”

Dr. Yun was also interviewed in 2019 by Bonnie Brown for HottyToddy.com and this interview is below.

Brown: Where did you grow up? Please talk about your childhood, family, and siblings.

Yun: I was born in Seoul, South Korea in 1929. I remember that I lived with my grandparents and my parents with five sisters. My sisters and I all emigrated to the United States. Two sisters are deceased. One lives near Chicago, one in Long Island, and the other in Detroit. My wife and I have one daughter who lives in Portland, Oregon.

Brown: Where did you go to school?

Yun: In 1936, I entered an elementary school near my home in Seoul several blocks away. I enrolled in a middle school (7th to 10th grades) which was about two miles away from my home. Those are from 1942 to 1946. Since Korea was a colony under the Japanese, we have to take the Japanese educational system; everything was taught in Japanese but I learned Korean from my parents.

In 1946, after the end of World War II, we became independent from Japan. I entered a preparatory school which was a part of the Seoul National University. This prep school was similar to a German gymnasium system (a type of school with a strong emphasis on academic learning) enforcing math and foreign languages. I had two years of high school just after the Japanese left Korea.

I advanced to an undergraduate program as a chemistry major and finished my undergraduate degree in 1952 which was during the Korean conflict. I was drafted and served two and a half years in the South Korean Army and was discharged in 1955.

I was admitted to the University of Cincinnati in 1956 and completed a Ph.D. degree in 1961.

Brown: How did you choose the University of Cincinnati?

Yun: From 1946 until 1952, Korea depended on U.S. aid in the national public schools. Much of that aid was in the form of army supplies—educational manuals used in the military. My freshmen through senior high school years, we studied English text. I didn’t know anything about the various colleges. But in my sophomore year, I took organic chemistry and the textbook author was from the University of Cincinnati, so I thought that would be a good place to study.

Brown: What subjects were hardest for you in school?

Mrs. Yun with Dr. Yun on the occasion of his retirement in 1998.

Yun: The difficult subjects for me were physics and mathematics.

Brown: Who influenced your career choice?

Yun: My father, who suggested that I should study science but not law. My father was a merchant who had two years of college. I was 27 when I started my graduate work at the University of Cincinnati. My wife went to LSU but later attended Ohio State.

Brown: Tell us how/when your Ole Miss “story” began? Who hired you? How long did you work at Ole Miss?

Yun: I had two post-doctoral positions—one at the University of Maryland and the second one at the Research Council Lab in Canada. Since the post-doctoral positions were not renewable, I began to look for a teaching position. I had several offers, but the offer from Ole Miss was the best. Dr. Robert B. Scott, Jr, Chair of the Chemistry Department hired me. Dr. Andrew Stefani recommended me. Dr. Scott was my Department Chair but he also became my friend. He and his wife, Russell, helped me and my wife a lot, teaching us about Southern culture. I joined the Department of Chemistry in 1968 and taught general chemistry, physical chemistry, and graduate courses in quantum chemistry and statistical thermodynamics for 31 years. I retired in June 1998.

Brown: What did you know about Ole Miss before you accepted a position here?

Yun: The only information I had was the information provided by the American Chemical Society. So I didn’t know much about the university before I arrived. When I came to Oxford, there were about 5,000 students. My wife and I lived in Northgate Apartments on campus (faculty and staff housing). I remember the first person who helped me was Mrs. Margaret Fields. She was very kind and very helpful.

Brown: Describe your most memorable days at work.

Yun: Teaching a large class of freshmen, fresh from their high school was challenging. That was some experience! For the first two years, I was assigned smaller classes because I was less experienced. However, after that I got the large freshmen classes.

Brown: What do you consider to be the highlight of your career?

Yun: In 1981, I received the Elsie M. Hood Outstanding Teacher Award. I also received the Cora Lee Graham Outstanding Teacher of Freshmen award from the College of Liberal Arts and the Phi Eta Sigma Honor Society’s Outstanding Teacher Award.

Brown: What accomplishment are you most proud of?

Yun: Teaching! There have been more than 6,000 students who went through my classes during my years of teaching, which generated many well-known doctors and pharmacists.

Brown: If there was something in your past you were able to go back and do differently, what would that be?

Yun: Be nice to under-prepared students. I didn’t mind repeating answers to questions. Repetition in the explanation is a virtue. I was willing to repeat it until the students understood the concept.

Brown: What is the best advice you ever received?

Dr. & Mrs. Yun pictured with one of his oil paintings. He has sold over 60 paintings. Photo courtesy of Dr. Yun.

Yun: Be patient and don’t jump to conclusions.

Brown: If you could have an all-expenses paid trip to see any famous world monument, which monument would you choose?

Yun: I’d travel to the Canadian Rockies. It’s so beautiful there! I lived in Canada and Boulder, Colorado. I loved visiting Estes Park and other sites each weekend.

Brown: What do you do to improve your mood when you are in a bad mood?

Yun: Listen to classical music.

Brown: Tell us something about yourself that not many people may know.

Yun: I used to do oil painting, landscapes. I took lessons from Oxford artist Connie Flake around 1985. I also enjoyed getting to know Clarksdale native Jason Bouldin, son of portrait artist Marshall Bouldin. Jason was a freshman in my chemistry class and came to me to tell me at the end of his freshman year that he was going to Harvard to major in art history. Jason has followed in his father’s footsteps and has become a noted artist in his own right. I no longer paint but I enjoyed it very much.

Brown: What gives you great joy?

Yun: Reading and listening to music. I like reading old classics. I like German novels of the 18th and 19th centuries. I like reading about human history, the creation of the university, etc. And I love listening to classical music.

Three Chemistry Majors Receive Prestigious Goldwater Scholarship!

Posted on: March 25th, 2022 by nhammer

Congratulations to Matt Knerr, Ethan Lambert, and Ally Watrous for being awarded the prestigious Goldwater Scholarship!

For the first time at the University of Mississippi, three students have been awarded Goldwater Scholarships in a single year.

Ethan Lambert, of Corinth; Reinhard “Matt” Knerr, of Paducah, Kentucky; and Alexandria “Ally” Watrous, of Lexington, Kentucky, all members of the Sally McDonnell Barksdale Honors College, have become the university’s 19th, 20th and 21st winners.

The Goldwater is one of the oldest and most prestigious national scholarships in science, technology, engineering and mathematics fields. It supports exceptional sophomores and juniors who show promise in becoming the next generation of research leaders in these fields.

This year, the Barry Goldwater Scholarship and Excellence in Education Foundation awarded 417 scholarships from a pool of 1,242 outstanding undergraduates nominated by 433 institutions.

“Ethan, Matt and Ally have all presented an incredible commitment to a career in research, and a genuine display of intellectual curiosity,” said Vivian Ibrahim, director of the UM Office of National Scholarship Advisement. “This is the first time UM has had three Goldwater scholars. We couldn’t be more excited for them.”

In recent years, the office has had steady success in recruiting competitive students for the Goldwater, Ibrahim said.

Knerr, Lambert and Watrous follow in the footsteps of Ole Miss Goldwater scholars Ivy Li and Austin Wallace in 2021, William Meador and Jax Dallas in 2020, and Addison Roush in 2019.

An Annexstad scholar, Lambert is set to graduate in 2023 with a bachelor’s degree in chemistry with an emphasis in chemical physics and a minor in mathematics.

“I am thrilled to be named a Goldwater Scholar but this accomplishment would not have been possible without the incredible people around me in the lab,” he said. “They taught me new techniques, proofread and answered my questions at 2 a.m. when I couldn’t sleep.

“I would be a fraction of the person I am without them around me.”

Lambert hopes to apply for a graduate research fellowship from the National Science Foundation next year to fund a doctorate in chemistry with a focus on studying how to use light to induce electron transfers between small molecules. This work has potential real-world applications in solar energy conversion.

Already first author on three published research papers and co-author of a book, Lambert has been working with Nathan Hammer, UM professor of chemistry and biochemistry.

“It has been a joy mentoring Ethan in the lab,” Hammer said. “He truly has the love for science and the aptitude for research. I expect great things from him for the remainder of his time with us at UM and beyond.”

Knerr is a Stamps scholar who is pursuing a degree in biochemistry, with minors in neuroscience, biological sciences, environmental studies and psychology.

“I am fascinated by aging,” he said. “My time abroad – in Spain, Costa Rica and the Netherlands – has really shed light on different ways to approach how we age.

“In the future, I want to be able to look at aging from a scientific angle as well as a moral and humanistic one.”

Knerr has four published articles and has worked Joshua Bloomekatz, an assistant professor of biology.

“Matt is a dynamic student with a passion for research, who shows great promise as a physician scientist,” Bloomekatz said.

Watrous is the only Ole Miss sophomore to be awarded a Goldwater, which will provide funding for her junior and senior years at the university. She is pursuing bachelor’s degrees in chemistry with a chemical physics emphasis, in physics and in German with minors in French and mathematics.

In the long term, Watrous is interested in collaborating internationally while conducting research in computational chemistry.

“The whole national scholarship and Goldwater process reaffirmed that grad school is something I want to do and can achieve,” she said.

Watrous has three peer-reviewed papers and one cover article to date as part of the UM Computational Astrochemistry Group, headed by Ryan Fortenberry, associate professor of chemistry and biochemistry.

“Ally is an absolute joy to have in our group, and I count myself lucky to be on her team through her education,” Fortenberry said. “Most often, about the time that students get trained, they leave. However, she’ll be around for a few more years, and I look forward to continuing my collaboration with her.”
