Models of Cadmium Absorption by Italian Parsley

Brittany E. Johnson, Bandana Upadhyaya

Abstract


The effect of soil pH on cadmium absorption by Italian Parsley (Petroselinum crispum var. neapolitanum) was investigated using two models: In Model 1, parsley plants were grown in self-watering pots containing cadmium contaminated soil; in Model 2, plants were grown in the upper chamber of Magenta jars where cadmium was fed to the plants from the lower chamber using a wicking system. Percent cadmium absorption in the shoots of parsley plants grown using Model 2 (7.61% to 13.1 %) is significantly higher than those grown using Model 1 (1.73 % to 4.04 %) in acidic, neutral and basic soils. However, no similar difference was observed in the roots. Percent absorption in the roots of parsley ranged between 21.31% to 34.42% in Model 1 and 13.178% to 32.29% in Model 2. The results of this study show that soil pH does not affect the amount of cadmium absorbed by parsley.
