In order to preserve the ecological quality of Aby lagoon, the aim of this study is to determine, according to seasons, spatiotemporal distribution and origin of phthaltes in the sediments of this lagoon. To do this, from September 2007 to July 2009, during seasonal sampling campaigns, sediment samples were collected at twenty (20) stations distributed along Aby lagoon. Analysis of the sediment samples, using gas chromatography-mass chromatography (GCMS- QP2010 plus), revealed presence of eight phthalates in the lagoon’s sediments. These are dibutyl phthalate (DBP), di (2-ethylhexyl) phthalate or bis (2-ethylhexyl) phthalate (DEHP), dimethyl glycol or di (2-methoxyethyl) phthalate (DMEP), phthalate di (2-methylpropyl) or diisobutyl (DIBP), dihexyl phthalate (DHP), di-isodecyl phthalate (DIDP), butyloctyl phthalate (BOP) and didecyl phthalate (DDcP). Areas of high population density as well as areas under the influence of the rivers that feed Aby lagoon contain more phthalates. However, the area under oceanic influence is free of phthalates. Statistical processing of data, using STATISTICA 7.1 and ADE-4 softwares, showed that the phthalates are continental and anthropogenic origin.

Abstract: (french)
En vue de préserver la qualité écologique de la lagune Aby, le but de cette étude est de déterminer, en fonction des saisons, la distribution spatiotemporelle et l’origine des phtalates dans les sédiments de la lagune Aby. Pour ce faire, des campagnes de prélèvement d’échantillons de sédiments ont été faites, de Juillet 2007 à Août 2009, en vingt (20) stations réparties sur la lagune Aby. L’analyse des échantillons de sédiments au GCMS- QP2010 plus (couplage chromatographe en phase gazeuse et spectromètre de masse) a révélé la présence dans les sédiments lagunaires de huit phtalates que sont: le phtalate de dibutyle (DBP), le phtalate de di (2-éthylhexyle) ou phtalate de bis (2-éthylhexyle) (DEHP), le phtalate de diméthylglycole ou de di (2-méthoxyéthyle) (DMEP), le phtalate de di (2-méthylpropyle) ou de diisobutyle (DIBP), le phtalate de dihexyle (DHP), le phtalate de di-isodécyle (DIDP), le phtalate de butyloctyle (BOP) et le phtalate de didécyle (DDcP). Les zones de forte densité démographique ainsi que les zones sous influence des cours d’eau qui alimentent la lagune contiennent plus de phtalates. En revanche, la zone du chenal, sous influence océanique, est exempte de phtalates. Le traitement statistique des résultats des données à l’aide des logiciels STATISTICA 7.1 et ADE-4 a montré que les phtalates sont d’origine continentale et anthropique.
