A geology and hydrology professor will discuss the dangers of microplastics in rivers during a program in Oak Ridge on Thursday, September 29.

Martin Knoll is professor of geology and hydrology and chair of the Department of Earth and Environmental Systems at the University of the South. He will talk to the University of Tennessee Arboretum Society.

The program is at the UT Arboretum Auditorium at 901 South Illinois Avenue in Oak Ridge starting at 7 p.m. September 29. The talk is titled “Microplastics in the Tennessee, Cumberland, and Rhine Rivers: Why We Should Care.”

Knoll’s presentation will focus on his research investigating the concentration and types of microplastics found in the three rivers, a press release said. Special emphasis will be placed on his recent findings about the major sources of these microplastics and what might be done to reduce their numbers.
