Identification and quantification of phthalates in water and sediment of Ori Stream, Iwo, Southwestern Nigeria using high performance liquid chromatography

摘要

This study provides data on distribution of phthalate esters (PAEs) in the water and sediments in the Ori stream, Iwo, Nigeria. The liquid-liquid extraction method was employed, followed by cleaned up in an alumina column using hexane. Chromatographic separation and quantification were done using Zorbax Eclipse AAA C18 analytical column. The concentrations of DMP, DBP, DEP, and DPP in water (µg/L) ranged from 1.29±1.3 in DBP to 938±780 in DMP while in sediment (µg/kg) ranged from 12.7±15 in DEP to 152±140 µg/kg in DBP. These concentrations were above the USEPA limits of 3 µg/L as recommended for phthalates in water.
