UGA Skidaway Institute of Oceanography graduate student Kun Ma has received $25,000 in research funding as part of the Georgia Sea Grant Research Traineeship Program. Ma will use the funds to support her work studying microplastic pollution in Georgia’s marine ecosystem. The project is titled “Determining photodegradation rates and products of textile-derived plastic microfibers in aqueous environments.”
Because the study of microplastics in a marine environment is still very new, there are many basic questions about microplastic distribution, environmental effects, and the sources and sinks of the microplastics. Ma’s focus with this research program is to examine one loss pathway, the degradation of microplastics and microfibers by sunlight in estuarine and marine environments. There are at least 50 trillion microplastic particles in the global ocean and up to one trillion microplastics in Georgia’s waterways alone.
“Knowledge of microplastic degradation pathways is essential to water management of coastal ecosystems, and many types of larger plastics can be degraded by exposure to light,” Ma said. “However, there are no published studies on the rate or degradation products of plastic microfibers in aquatic environments. My study will serve as an initiative to fill this knowledge gap.”
Sea Grant Research Trainees undertake research projects that advance the goals and objectives in Georgia Sea Grant’s strategic plan. Ma’s project will address two goals, maintaining a healthy coastal ecosystem and promoting environmental literacy.
The research will form part of Ma’s thesis research. The results will be submitted for publication in a peer-reviewed scientific journal and will be presented at regional and national conferences. In addition, an educational poster summarizing results of the project will be showcased at public special events reaching diverse audiences, such as Skidaway Marine Science Day, Savannah Earth Day Festival and the World Oceans Day Celebration.
Ma is a Ph.D. student in the UGA Department of Marine Sciences. Her faculty advisor at Skidaway Institute is Jay Brandes. Her professional mentor on the project will be UGA Marine Extension and Georgia Sea Grant educator Dodie Sanders. The funding is for one year, beginning August 1.
