Trace organic compounds (Phtalates, NEP, AOX) brought in by the land application of wastewater treatment plant sludges

Abstract : The behaviour of three characteristic groups of trace organic compounds (Phtalates, Nonyl Phenol Ethoxylates and Chlorophenols) in a ground-plant system has been carried out. With the aim of reclaiming biosolids for agriculture, the transfer potential has been studied in hydroponically growing tomato plants (Lycopersicon esculentum var. Rondello), where transfer should be optimal. Plant containers inside a temperature and humidity controlled plant house were used. There were two types of experiment. Trace organic compounds 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 a difference in behaviour of the trace organic compounds according to the part of the plant and method of introduction. Generally speaking, for the experiments using pure substances, the roots absorb higher quantities of trace organic compounds and block to a greater or lesser extent their transfer to the above ground parts of the tomato plant. However, with the biosolids filtrate, the Di-ethylhexyl phtalate and the Nonyl ethoxylate phenol can be traced all over the plant.
