TI  - First report on the presence of small microplastics (</= 3 mum) in tissue of the

AB  - There is limited research on the ingestion of microplastic particles (MPs) by 
      fish from the southern part of the Mediterranean Sea. This study provides the 
      occurrence of small MPs (</=3 mum) in the gastrointestinal tract and muscle of adult 
      benthopelagic fish Serranus scriba (L.1758), caught along Tunisian coasts. MPs 
      were extracted from selected tissues using a potassium hydroxide digestion method 
      (KOH 10%) and then quantified, and their chemical structure was characterized 
      through Raman microspectroscopy. The results highlighted that MPs were present in 
      all samples. The average abundance of MPs per gram of fish tissue identified 
      through successive filters of 3 mum, 1.2 mum, and 0.45 mum differed significantly 
      among the sites. The properties of the MPs extracted indicated that 
      polyethylene-vinyl-acetate (PEVA: 33.45%), high density polyethylene (HD-PE: 
      17.33%), and fragments were the most abundant plastic types and shape found, 
      respectively. Among those, most MPs were found at a size class of 3-1.2 mum 
      ( approximately 60%), especially in the muscle, suggesting a high transfer of MPs into the 
      human diet. Our field work also aimed to explore the effects observed in the 
      gastrointestinal tract with a battery of biomarkers assessing oxidative stress 
      and neurotoxicity. The preliminary results of this study showed the existence of 
      a link between small MPs, sites, and their associated urban activities and 
      induced oxidative stress. However, more detailed studies are required to evaluate 
      the transfer of MPs into tissues and the potential impacts of this transfer on 
      human health.
