Initial Investigations Into Tools For Phytoremediation Of Lead From Urban And Suburban Landscapes, Michael Taylor Bryant

LSU Master's Theses

Lead is a pervasive and ongoing problem in the landscape, especially in urban and suburban areas where historic use of tetraethyl lead gasoline and leaded paint has increased background amounts to dangerous levels. One method to solve this problem is the use of hyperaccumulator plant species, capable of concentrating over 1000 ppm Pb into their tissues. This is a slow process, even with hyperaccumulators, so the use of amendments to improve Pb solubility has gained popularity, though with mixed results. This study examined Trachelospermum asiaticum, Ardisia japonica, and Ophiopogon japonicus, three common landscape groundcovers used in Louisiana, …
