Preliminary evaluation of plasticizer and BPA in Tunisian

In this study, 18 plasticizer (phthalates, adipates, sebacates, and others) and BPA residues in some cosmetic samples collected from Tunisian market are evaluated by micro-matrix solid-phase dispersion combined with GC-MS. In parallel, the impact of these molecules and the cosmetics in the human epithelial cell lines is investigated.

Hence, these preliminary results confirmed the presence of illicit drugs in the influent wastewater samples. For example, quantification ranges for cocaine were found to be 25-450 ng/L in influent wastewater samples. Significant differences for cocaine consumption across the two sampling methods were observed.
