Biomonitoring of Metallic Trace Element in South Brittany Coastal (France) Using Oyster (C. Gigas): A Local Food Source

International audience Oyster samples (crassostrea gigas) were collected from seven mariculture site in Quiberon bay and gulf of Morbihan (South Brittany coastal area) for the investigation of metallic trace elements (MTE) assessment. Cu, Zn, Cd and Pb were analyzed by using inductively coupled plas...

Description
Summary:International audience Oyster samples (crassostrea gigas) were collected from seven mariculture site in Quiberon bay and gulf of Morbihan (South Brittany coastal area) for the investigation of metallic trace elements (MTE) assessment. Cu, Zn, Cd and Pb were analyzed by using inductively coupled plasma-mass spectrometry after acid digestion process. Oyster tissue, SRM1556a was used to validate the methods and the results show a good agreement with the certified values. The mean levels of Cu, Zn, Cd and Pb in oysters flesh were 3.57, 32.8, 0.04 and 0.24 mg/kg wet wt., respectively. MTE concentrations in the flesh were assessed for human consumption according to provisional tolerable weekly intake (PTWI) and provisional tolerable daily intake (PTDI). Due to their bioaccumulation capacity of heavy metals, both oysters' species had the potential of being used as biomonitors to control the aquatic contaminations of heavy metals.
