Broccoli, endive, lettuce, onions, spinach, tomatoes, and perennial ryegrass were cultured in pots or pillow packs containing growth media that had been amended with increasing percentages of soft coal fly ash. The crops absorbed selenium in proportion to the percentage of fly ash in the growth media. Broccoli, onions, and lettuce absorbed the highest concentrations of selenium. The levels of selenium in ryegrass were maintained through five successive cuttings of the plants. Endogenous mutagens were found in endive, lettuce, and ryegrass. Endive and lettuce absorbed and translocated mutagens from the fly ash amended soil whereas ryegrass did not have this ability. A rat microsomal enzyme preparation was able to partially deactivate these mutagens to innocuous compounds.
