Metal Uptake by Plants at Small Arms Ranges.

A greenhouse study was used to screen 12 plant species commonly found in the northeastern US for the uptake of lead (Pb) and zinc (Zn).  All of these species are typically found on military training ranges in the northeastern US.  The species tested were annual ryegrass, birdsfoot trefoil, Kentucky bluegrass, Canada bluegrass, creeping bentgrass, creeping red fescue, crabgrass, perennial ryegrass, tall fescue, yellow foxtail (zinc only), and hard fescue and Bermudagrass (lead only).  All the species tested are introduced species, and all are grasses except for birdsfoot trefoil, which is a legume.
