Afrachanna Butler, U.S. Army Corps of Engineers research physical scientist, and Catherine Thomas, U.S. Army Corps of Engineers research biologist, will address several environmental concerns during a seminar at 3:30 p.m., May 7 in Hardin Hall 901. The seminar is free and open to the public.
Butler's presentation, "Determination of Root Exuded Compounds from Bermuda Grass and Perennial Ryegrass," will address concerns related to the potential environmental impacts of lead contamination associated with military training ranges.
Butler has worked at the Environmental Laboratory, United States Army Engineer Research and Development Center (ERDC) in Vicksbug, Mississippi since 2001. She began her career on a temporary appointment as a contract student and progressed into her current full-time position in 2007.
Thomas' presentation, "Environmental Impact Assessment of the Copper Bullet," will address concerns related to the increasingly recommended use of copper projectile bullets for both military training and civilian shooting sports.
Thomas has worked at the ERDC for three years. Her current research investigates the propensity of copper metal to corrode in soil under varying conditions.
Anyone with questions regarding the seminar should contact Tala Awada, professor of plant ecophysiology, at 402-472-0232 or tawada2@unl.edu.
