“…This enzyme is directly responsible for the removal of the superoxide anion (O 2 - ) with the formation of hydrogen peroxide (H 2 O 2 ) that can be used by catalase (CAT) or glutathione peroxidases (GPx) enzymes [ 61 ]. Under stressful conditions, ROS can be overproduced, and in response, bivalves are known to activate antioxidant defenses (e.g., [ 47 , 52 , 62 , 63 , 64 , 65 , 66 , 67 ]). A similar response was described here for R. philippinarum exposed to both contaminants showing increased antioxidant activity compared to control clams in an attempt to eliminate ROS and mostly to prevent cellular damage (e.g., LPO).…”

Studies have described the occurrence of nanoparticles (NPs) in aquatic ecosystems, with particular attention to the widely commercialized carbon nanotubes (CNTs). Their presence in the environment raises concerns, especially regarding their toxicity when co-occurring with other pollutants such as metals. In the present study, changes to the metabolic capacity, oxidative, and neurologic status were evaluated in the presence of carboxylated multi-walled CNTs and chromium (Cr(III)) using two of the most ecologically and economically relevant filter feeder organisms: the clam species Ruditapes decussatus and R. philippinarum. Results indicated that although Cr, either alone or in combination with CNTs, was found in a similar concentration level in both species, a species-specific Cr accumulation was observed, with higher values in R. decussatus in comparison with R. philippinarum. Inhibition of antioxidant defenses and neurotoxic effects were detected only in R. philippinarum. The interaction between contaminants seems to have no effect in terms of antioxidant enzyme activities and neuro status. Nevertheless, synergistic activation of responses to both contaminants may have altered the metabolic capacity of bivalves, particularly evident in R. decussatus. While both clams are tolerant to both contaminants (alone and together), they showed a relevant accumulation capacity, which may represent a possible contaminant transfer to humans.

“…In addition, the area is exposed to household wastewater, as well as diffuse runoff from agricultural land and highways [ 67 ]. The adverse impact of industrial pollution has been described in numerous research papers [ 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 ]. Sampling sites where sabrefish were caught differ in the level of anthropogenic load ( Figure 1 ).…”

Nowadays, the problem of inland water pollution is acute. It is caused by vast industrial growth and agricultural intensification. Concentrations of Cd, Pb, Zn, Cu, Mn, Fe, Mg, and Kwere determined in the muscles, liver, and gonads sabrefish from Rybinsk Reservoir areas with different anthropogenic loads. The tissue samples were analyzed by atomic absorption spectrometry. Heavy metals accumulated more intensively in the body of fish from more polluted areas of the reservoir. Among the analyzed elements, the maximum accumulation levels were found for K, Zn, and Fe and the minimum levels were observed for Cd and Pb. The gonads contained the largest concentration of Cd and Mn, the muscles contained the highest concentrations of Mg, and the other elements mainly accumulated in the liver of sabrefish. The THQ and HI values for all elements did not exceed 1, which suggests that there is no potential non-carcinogenic risk to human health. The target values of carcinogenic risk (TR) for cadmium ranged from 8.32 × 10−6 to 1.22 × 10−4 in the muscles. The increased content of cadmium in the gonads of sabrefish not only poses a risk to human health, but also to the reproduction of this species in the Rybinsk Reservoir.
