PLANT UPTAKE OF SELECTED TRACE ORGANIC COMPOUNDS FOLLOWING THE LAND APPLICATION OF BIOSOLIDS
Abstract:A study of the behavior of two typical groups (Polycyclic Aromatic Hydrocarbons (PAH) and PolyChloroBiphenyls (PCB)) of trace organic compounds (trace organics) in a soil - plant system has been carried out, with the reclamation of wastewater treatment plant biosolids for agriculture in mind. To study the uptake potential, carrot plants (Daucus carota L. var. Amsterdam A.B.K. Bejo) have been grown in aquiculture, to provide optimal transfer conditions, in plant containers inside a temperature and humidity regulated plant house.
There were two types of experiment. The trace organics have initially been introduced as pure substances. A second experiment has been carried out under the same conditions, but using wastewater treatment plant biosolids.
The results clearly show that the trace organics accumulate in the carrot skin.
