“…This can be due to increased ROS production with increase heavy metal concentrations and forms the basis for significant positive correlation (p < 0.01) between the four antioxidants and the heavy metals determined in this study. Similar findings were reported in several works of literature [15,18,19].…”

The pursuit of a good candidate to biomonitor environmental pollutants has been on the increase. In this study, the concentrations of Fe, Mn, Cu, Zn, Cd, Cr, Pb and Ni in sediment, seawater and seagrass Cymodocea serrulata compartments and antioxidant enzymes activities in C. serrulata were determined. Our results revealed that bioconcentration factors for all the metals were less than 1 (BCF < 1) and concentrations in seagrass compartments were in the order root > leaf > rhizome for Fe and Mn, leaf > root > rhizome for Cu, Zn, Pb and Ni, and root > rhizome > leaf for Cd and Cr. Effect range low concentrations (ER-L) revealed that Cu, Zn, Cd, Pb and Ni concentrations were above ER-L values and Cr concentration was below ER-L values while concentrations in seawater for all the heavy metals were above the estimate average element concentrations in seawater (ECS). Significant variation (p < 0.05) was recorded for heavy metals in sediment, seawater, seagrass compartments and heavy metal concentrations across stations. Influence of heavy metals on antioxidant enzymes activities; catalase (CAT), superoxide dismutase (SOD), glutathione S-transferase (GST) and acetylcholinesterase (AChE) were recorded, and high activities of the antioxidants were recorded in station S8 corresponding to high concentrations of heavy metals in the same station. There is a need for the promotion of biomonitoring networks across the marine environment using C. serrulata and antioxidant enzymes as biomarkers of oxidative stress caused by environmental pollutants.

“…Our findings are coherent with Lacroix et al [90] whose data suggested a higher GSH production, which could subsequently enhance ROS scavenging and phase-II biotransformation. Furthermore, we agree with Ferreira et al who found in their study on transplanted oysters from an estuary in Brazil that the increased GR activity could be explained with a possible increase in the cellular GSH supply [115].…”

“…As explained by Regoli and Guiliani, and Ferreira et al, GR is an NADPH-dependent enzyme, involved in the reduction of oxidized glutathione (GSSG) to GSH, previously needed by antioxidant and biotransformation enzymes (e.g., GPx and GST) for ROS and chemical detoxification [115,116].…”

“…A variety of techniques such as atomic absorption spectroscopy (AAS) [5] [6] [7], wavelength dispersive X-ray fluorescence (WDXRF) [8], and inductively coupled plasma mass spectrometry (ICP-MS) [9] [10] [11] are commonly used to analyze oyster tissue. However, many of these techniques are not readily translatable into field instruments [12] due to prolonged and complicated sample preparation steps that produce chemical residues.…”

The analysis of metals in aquatic organisms is of great importance due to the health problems they can cause to be consumed by human beings. In this study, the Laser-Induced Plasma Spectroscopy (LIBS) technique is evaluated as an alternative method to identify Cu in Crassostrea virginica oysters' tissue. It focuses on the characterization of oysters caught a natural bank and the identification of different Cu concentrations. To carry out experimentation, oyster samples were collected in autumn (October 2017) and spring (May 2018) from San Andres Lagoon, Aldama, Tamaulipas. A single pulse Nd:YAG laser (1064 nm) was used, and tissue was contaminated with 0, 2, 10, 20, 50, and 100 μg/g of Cu. In tissue were identified atomic lines for Ca, Cr, Mg, Mn, Na, N, O, and H. However, the intensities of emission lines for autumn samples were greater than spring samples. Cu emission lines at 324.6, 327.1, 510.3, 515.1, and 521.5 nm were found for contaminated pills. The intensity of emission lines showed a linear increase with the concentration; whereby, they can be used as calibration curves to quantify Cu concentrations in oyster tissue.
