Cabbage and collards grown in pots in municipal sludge amended soil accumulated cadmium. Glutathione content of both young and old leaves was significantly higher in the sludge-grown vegetables than in the corresponding control plants, likely in response to stress factors imposed by the sludge amendment. Putrescine, spermidine, and spermine, measured only in the collards, also increased, possibly by induction due to cadmium accumulation or to general metals stress. Cabbage loopers foraging on the sludge-grown plants assimilated and concentrated cadmium from the contaminated foliage. Putrescine, spermidine, and spermine also increased in the loopers associated with the collards whereas glutathione did not. The insects grew larger but developed more slowly on the sludge-grown collards than on the corresponding control plants. Possible accumulation of cadmium in insects by insect-consuming birds is discussed.
