Absorption of 42 elements by plants representing major classes of edible garden crops on sludge-amended soil were studied. Sludge from the city of Ithaca, NY was used. The Ithica sludge process includes primary settling, trickle filtration, anaerobic digestion and finally vacuum filtration with the addition of lime. It had a pH of 7.2 and had remained in a pile outside for one year. The crops planted were: bush bean, cabbage, carrot, onion, tomato, millet and potato. Only the edible plant portions were collected for analysis. The sludge showed relatively high levels of Cd, Cr, Cu, Mo, Ni, Pb, Ti, and Zn. B, Br, Ca, Cd, Cl, Cr, Cu, Fe, Hg, I, Mo, Ni, Sb, Sc, Se, Ta, V, W and Yb were found higher in at least 3 of the crops grown during the first year on sludge-amended soil as compared to the control. Ca, Cd, Cl, Cu, Fe, I, Mo, Ni, W and Yb were most consistently high, their plant concentrations in the sludge-soil treatment exceeding those of the controls in 5 or more of the crops studied. Plant absorption of the elements B, Br, Cd, Cl, Cu, I and Ni would probably not be greatly affected by the higher pH (7.1) of the sludge-soil mixture as compared to the soil alone (5.3). Absorption of Ca, Mo and Se would be favored by the rise in pH while absorption of iron would tend to be decreased. Al, B, Br, Ca, Cd, Cu, Fe, and K were most consistently high in second year crops from the sludge-soil mixture. Cr and Cu were lower in second year crops. Ni in beans, Cd and Sb in onions and Hg in millet attained concentrations of some concern in the first year crops.
