Bioaccumulation of heavy metals in the terrestrial isopod Porcellionides pruinosus in the vicinity of Gabes-Ghannouch industrial complex

Effects of trace metal elements on ultrastructural features of hepatopancreas of Armadillidium granulatum Brandt, 1833 (Crustacea, Isopoda)

“…The current study showed that Cu and Zn contents in the metabolism of A. granulatum were dose‐dependent. The same result has been already reported by numerous researchers (Costa, Bouchon, van Straalen, Sousa, & Ribeiro, ; Ghemari et al, ; Ghemari et al, ; S. P. Hopkin et al, ; S. P. Hopkin, Hames, & Bragg, ; S. Hopkin, Hardisty, & Martin, ; S. P. Hopkin & Martin, , ; Hussein, Obuid‐Allah, Mohammad, Scott‐Fordsmand, & Abd El‐Wakeil, ; Köhler et al, ; Loureiro, Sampaio, Brandao, Nogueira, & Soares, ), confirming the ability of terrestrial isopod species to cope with high amounts of trace metals from sediment and diet. In the two species Porcellio laevis and Armadillidium vulgare , Mazzei et al () showed that the accumulation of metals depends on the concentration and on the tested metal.…”

“…Analytical procedures were determined using the BCR‐483 (sewage sludge amended‐soil) and the ERM®‐CE278 (mussel‐tissue) as certified materials for sediments and animals, respectively, issued from the European Institute for Reference Materials and Measurements (IRMM). The measured metal concentrations in the two certified materials did not differ more than 10% from the certified concentrations (Ghemari, Waterlot, Ayari, Douay, & Nasri‐Ammar, ).…”

“…In fact, P. laevis species sampled from Tunisian industrialized areas was considered as a macroconcentrator of both Cu and Zn (Ghemari et al, ). Likewise, Porcellionides pruinosus sampled from the industrial complex of Gabes‐Ghannouch was considered as a Cd, Zn, and Cu macroconcentrator (Ghemari et al, ). For other crustaceans, Jelassi et al (, ) showed that the Talitrid amphipods Orchestia mediterranea and O. montagui were considered as macroconcentrator of Cu and Zn.…”

“…To assess metal accumulation in A. granulatum individuals, the bioaccumulation factor (BAF) was calculated. According to Ghannem, Khazri, Sellami, and Boumaiza () and Ghemari et al (, ), it is defined as the ratio between the measured metal concentrations in woodlice (mg kg −1 dw) and that of the soil (mg kg −1 dw). Based on Dallinger's classification (Dallinger, ), BAF values could be interpreted as follows: If BAF < 1, the species is deconcentrator. If 1 < BAF < 2, the species is microconcentrator. If BAF > 2, the species is macroconcentrator. …”

Physiological and histopathological responses of Porcellio laevis (Isopoda, Crustacea) as indicators of metal trace element contamination

“…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).…”
