Induced Hyperaccumulation: Metal Movement and Problems

Induced hyperaccumulation of lead was studied in field and pot trials in northern France (over Cu/Pb/Cd-rich soils polluted from a nearby smelter at Auby, France) and in New Zealand. The plants studied were Agrostis tenuis (1), Arrhenatherum elatius (2), Berkheya coddii (3), Brassica juncea (4), Cardaminopsis halleri (5), Silene humulis (6), and Thlaspi caerulescens (7).
