• Resumen

  • It has been reported that microplastics (MPs) can adsorb various environmental chemical contaminants, thereby serving as a sink and source of these associated chemical contaminants and po- tentially changing their toxicity, bioavailability, and fate. Among these compounds different families of so called organic contami- nants of emerging concern (OCECs) attract more and more atten- tion in recent years. For this, we have prospected in this work to identify and quantify OCECs by using Ultra High Performance Liq- uid Chromatography coupled to mass spectromtetry in tandem detector (UHPLC-MS/MS) in the influents of wastewater treat- ment plants (WWTPs) from Las Palmas de Gran Canaria (Spain) and Mahdia (Tunisia). Results indicated the contamination of MPs isolated from infl uent LPA-WWTP by four OCECs and MPs isolated from influent Mahdia-WWTP by three of them. The simultaneous occurrence of multivarious contaminants does not go with con- sequences on the environment and human health. In fact a bat- tery of eucaryotic (comet and micronucleus assays) and procary- otic assay (SOS chromotest) were carried out and showing a high correlation between the level of contamination with OCECs and the level of the DNA damage.
