Abstract
Phthalate esters are used as additives in plastics to improve mechanical properties, particularly flexibility. The contamination of soil samples by phthalate esters around four tributaries to the nm river was analyzed based on gas chromatography-mass spectrometry (GC-MS). All soil samples collected from the four tributaries, which include Anyangcheon and Seohocheon (expected polluted areas), and Gapyeongcheon and Namhan river (expected clean areas), were found to be contaminated by his(2-ethylhexyl) phthalate (DEHP). Soil around Anyangcheon was the most contaminated (113 ppb), about twofold higher than the ones around Seohpcheon (64 ppb), Gapyeongcheon and Namhan river (50 ppb). Based on the fact that DEHP contamination in sediments of the river tributaries around the country is as high as 2.04 ppm, it was concluded that DEHP contamination of the soils around the tributaries to the Han river is relatively low.
