Abstract
A significant number of plants were suggested potential to alleviate toxic levels of heavy metals in soils through phytoremediation. This research was to study the phytoremediation potential of several plants in heavy-metal polluted tropical soils. Soil samples were collected from experimental plots amended in 1998 with 0, 15, and 60 Mg industrial waste ha-1. The soil samples were planted in a glass-house experiment with 3 different plants i.e caisim (Brassica chinensis var. Parachinensis), water spinach (Ipomoea aquatica), and lettuce (Lactuca sativa). Plant parts (roots and shoots) and soil samples were harvested after a 4-week growth period and analyzed for Zn. The results show that the growth of plants was depressed by the increase in the soil Zn as affected by waste treatment, with water spinach being the most progressive and producing the greatest biomass. All plants significantly decreased the concentration of Zn in soils, with water spinach decreased the most significantly. The absorption of Zn increased with the soil Zn (high linear R2). Zinc was accumulated greater in plant roots than that in shoots. All plants were good Zn phytostabilizators.
