Organic Substances in Leachate from Landfill for Mixed Refuse

Comprehensive index such as BOD or COD is currently used to estimate water pollution by organic substances in leachate from landfill, and any component has not been characterized in it. In order to study organic substances in pit spill from mixed refuse and in leachate from landfill for mixed refuse without incineration procedure, organic compounds have been initially examined. As a result, amino acids and fatty acids contained in animals and plants, were detected in refuse pit spill, but not in leachate from landfill for mixed refuse. It is suggested that these are derived from the decomposition of organic components of waste inside landfill. When organic substances in leachate were analyzed by GC/MS, phthalic acid esters, DEHP and DBP, were identified in it on the basis of their mass spectra.
