Abstract
Aby lagoon is facing various anthropogenic pressures. The aim of this work is to look for phthalic acid esters in sediments of this lagoon. For this purpose, seasonal campaigns of sampling of sediments were done from September 2007 to July 2009. Samples analyses were possible thanks to use of chromatograph in gas phase with mass spectrometer (GC/MS). Determination of found molecules concentrations was realised by the method of internal calibration. The used internal standard is imidaclopride concentration of 2 mg/mL. Sediments samples analyses of Aby lagoon revealed the presence of eight phtalates. They are dibutyle (DBP), di (2-ethylhexyle) (DEHP), di (2-methoxyethyle) (DMEP), di-isobutyle (DIBP), di-isodecyle (DIDP), butyloctyle (BOP) and didecycle (DDcP) phtalates. DBP, DIBP; DEHP and DMEP are successively the most abundant phthalates in lagoon sediments; DHP, DIDP, BOP, and DDcP are poorly represented.
