Di(2-ethylhexyl) phthalate (DEHP) is mainly used as a plasticizer for flexible polyvinyl chloride (FPVC). The quantity of DEHP released into the environment from the DEHP production and the FPVC products manufacturing is estimated and reported in the Pollutant Release and Transfer Register (PRTR) system. The PRTR system, however, does not cover the releases of DEHP from FPVC products in use. In this paper, the quantity of DEHP emitted into the air from FPVC products in use was estimated. The quantity of DEHP contained FPVC was estimated using the amount of shipment and the lifetime function. Results of the estimation showed that "sheets for green houses" was estimated to be the main emission source and contributed half of the total emissions from FPVC products in use. Total DEHP emissions from FPVC products in use to the air were estimated to be 761 tons/year, which is comparable to approximately 50% of DEHP emissions in year 2001 reported in PRTR. It is concluded that FPVC products in use are a significant source of DEHP emissions to the environment, and the method presented here can be used to improve the emission estimations of chemicals similar to DEHP.
