Organophosphoric acid triesters (OPE) in various water sample at Osaka North Port Sea-Based Solid Waste Disposal Site were examined, to reveal the relation between the change of OPE concentration and the situation of waste disposal. OPE concentration rose suddenly by solid waste disposal into remained sea-surface directly (sea-surface disposal), and stopped rising on a certain level. TCEP and TCPP showed high concentration in OPE, the max of concentration of TCEP was over 30 μg·l-1. OPE concentration decreased as the interruption of sea-surface disposal. Major source of OPE were the combustible waste such as plastics or fibers which mingled with the incombustible waste which was permitted reclamation into this disposal site. Behavior of OPE concentration was about the same as water pollution index such as BOD or COD in both of the water inside of disposal site and the surrounding seawater.
