Phytomining for nickel, thallium and gold ScienceDirect

There are about 300 Nihyperaccumulator species, 26 of Co, 24 of Cu, 19 of Se, 16 of Zn, 11 of Mn, 2 of Tl (including new data in this present paper) and one of Cd ().Most of these plants were initially regarded as scientific curiosities until it was proposed by Chaney (1983)and Baker and Brooks (1989)that they might be used to remove pollutants from soils (phytoremediation).
