Five plant species, bean, broccoli, carrot, pepper, and tomato, were grown in pots containing either dewatered, aged sediment or a reference soil. Plant growth, development, and yield in the two soils were quantified. Edible and vegetative tissues from the plants were analyzed for 19 elements, including environmentally-important heavy metals and metalloids. Some plants grown in sediment showed a greater biomass and yield as compared to the Ag soil. Elemental analysis of the tissues revealed that only Zn and Mo were elements that were significantly greater in sediment-grown plants on a consistent basis. | | | | Date Created: | 12 07 2006 | | | | Agency ID: | RR-109 | | | | ISL ID: | 000000001336 Original UID: 1238 FIRST WORD: Metal | |
