Ethylhexyl Phthalate

This study investigated the occurrence of di (2-ethylhexyl) phthalate (DEHP) di-n-butylphthalate (DBP) and bisphenol A (BPA) in river sediment. The samples were collected from three selected points and extracted by sonication, using n-hexane and ethanol. The organic extracts were analyzed by gas chromatography with flame ionization detection (GC/FID). DBP and BPA were not detected. The average concentrations of DEHP range from 0.72 (±0.04) to 27.90 (± 3.05) ng g-1 of sediment. The best solvent for the extractions was n-hexane. However ethanol also shows good extraction yields of DEHP. These results showed an important anthropic contribution for the river contamination by endocrine disruptors.
