Abstract
To estimate trace element bioaccumulation in Armadillo officinalis, specimens were collected then exposed to contaminated sediments with copper and zinc for three weeks.
At the beginning of the experiment, the individuals were weighted and their masses were monitored every 7 days during 3 weeks. At the end of the experiment, the body metal concentrations were measured using flame atomic emission spectrometry. A mass gain was highlighted after trace elements exposure. The bioaccumulation factor results showed that the species could be considered as a macroconcentrator of copper (BAF > 2) and a deconcentrator of zinc (BAF < 2).
Microscopy observations of hepatopancreas cells showed morphological and histological changes even at the lowest concentration. Through these results, the isopod A. officinalis could be used as relevant monitor organisms for soil metal contamination.
