“…As part of terrestrial ecosystems, terrestrial isopods have been recently used as bioindicators to assess environmental quality and show promise as invertebrates (Ghemari et al, 2018;Ghemari, Waterlot, Ayari, Douay, & Nasri-Ammar, 2019a;Khemaissia, Jelassi, Ghemari, Maryline, et al,2019;Khemaissia, Jelassi, Ghemari, Raimon, et al, 2019;Nannoni, Mazzeo, Protano, & Santolini, 2015). Furthermore they are characterized by their wide geographic distribution, they are easily collected and reared in laboratory conditions (Costa, Bouchon, van Straalen, Sousa, & Ribeiro, 2013;Godet et al, 2011;Mazzei et al, 2014;Odendaal & Reinecke, 2003). Thus, their ability to accumulate considerable amounts of MTE was demonstrated (Gäl, Markiewicz-Patkowska, Hursthouse, & Tatner, 2008;Hopkin, Hardisty, & Martin, 1986;Hopkin & Martin, 1982;Köhler, Hüttenrauch, Berkus, Gr aff, & Alberti, 1996;Mazzei et al, 2014).…”
