“…[27] The strongest correlation in the gills was observed between Ni and Cr (r = 0.904), which was also the strongest correlation in any tissue. We have observed a strong correlation between Ni and Cr in the gills of crayfish in a prior study, [21] and similar effects were reported in other animals and plants, for example, two oyster species (Crassostrea hongkongensis and Crassostrea sikamea), [28] the macrophyte Phragmites australis [29] and the nile tilapia Oreochromis niloticus. [30] Weng and Wang reported that the correlation between Ni and Cr were present in the environment as well as the two species of oyster, suggesting that the correlation is not a function of the animals' metabolic processes, but a result of the fact that accumulation in bioindicator species reflects the metal amounts in their environment.…”

The accumulations of Al, Cd, Cr, Cu, Fe, Ni, Pb and Zn in the exoskeleton, gills, hepatopancreas and abdominal muscles of crayfish Astacus leptodactylus (Eschscholtz, 1823) were determined. The strongest correlation observed was between Cr and Ni in the gills (r = 0.904); moderate to strong correlations between Al, Cr, Fe, Ni and Cu were also observed in gill tissue. Disregarding the gills, the strongest correlation was found between Cu and Zn in the hepatopancreas (r = 0.808); the correlation between these two metals might have been a result of metallothionein activity. The accumulation of Pb was found to correlate with that of Cd in the exoskeleton, Cd and Zn in the gills, Zn and Cu in the hepatopancreas and Cu in the abdominal muscle. None of these correlations were present in lakewater and sediment samples, suggesting that the crayfish metabolism may be responsible for the co-accumulation of metal-metal pairs. As all correlations in non-gill tissues are observed between divalent metals, a shared transporter such as divalent metal transporter 1 might be involved in the accumulation of these metals.

“…Previous researches reported that the oysters Crassostrea hongkongensis and Crassostrea sikamea from the metal-polluted sites along the Jiulongjiang Estuary, Fujian Province, were severely contaminated by copper, which was marked by the blue or green tissues in oysters with the high tissue Cu concentration up to 19,000 μg/g dry weight (Weng and Wang, 2014). Therefore, it is necessary to elucidate the biological effects induced by metal pollution, which may be further used to predict the consequence of metal pollution.…”

“…As a marine filter-feeder, oysters are not only edible bivalves but play an important role in maintaining the marine ecosystem health in many estuarine systems (Weng and Wang, 2014). Due to its high capacity to accumulate metals, oysters such as Crassostrea hongkongensis, Crassostrea sikamea and Saccostrea glomerata are also preferable environmental bioindicators for metals (Goldberg et al, 1983).…”

The metal pollution has posed great risk on the coastal organisms along the Jiulongjiang Estuary in South China. In this work, two-dimensional electrophoresis-based proteomics was applied to the oysters Crassostrea hongkongensis from metal pollution sites to characterize the proteomic responses to metal pollution. Metal accumulation and proteomic responses indicated that the oysters from BJ site were more severely contaminated than those from FG site. Compared with those oyster samples from the clean site (JZ), metal pollution induced cellular injuries, oxidative and immune stresses in oyster heapatopancreas from both BJ and FG sites via differential metabolic pathways. In addition, metal pollution in BJ site induced disturbance in energy and lipid metabolisms in oysters. Results indicated that cathepsin L and ferritin GF1 might be the biomarkers of As and Fe in oyster C. hongkongensis, respectively. This study demonstrates that proteomics is a useful tool for investigating biological effects induced by metal pollution.

“…Tan et al (2015) found that the two species of oysters, Crassostrea hongkongensis and Crassostrea sikamea, from the metal-polluted sites accumulated extremely high concentrations of Cu in their tissues, which made C. hongkongensis and C. sikamea blue (light turquoise) and green (asparagus green), respectively. The Cu concentrations in the metal-contaminated oysters reached as high as 19,000 μg/g dry weight, however, the oysters still can survive and grow up in the metal-contaminated sites along Jiulong River Estuary, Fujian Province, China (Weng and Wang, 2014). Since excessive metals can induce adverse effects in aquatic organisms, the great concern has been raised over the health risks to aquatic organisms .…”

a b s t r a c t a r t i c l e i n f oMetal pollution has become a great threat to organisms in the estuaries in South China. In the present study, the oysters Crassostrea sikamea were collected from one clean (Jiuzhen) and five metal polluted sites (Baijiao, Fugong, Gongqian, Jinshan and Songyu). The tissue metal concentrations in oysters indicated that the five metal sites were polluted by several metals, including Cr, Ni, Co, Cu, Zn, Ag, Cd and Pb with different patterns. Especially, Cu and Zn were the major contaminants in Baijiao, Fugong and Jinshan sites. The metabolic responses in oysters C. sikamea indicated that the metal pollutions in BJ, FG, JS and SY sites induced disturbances in osmotic regulation and energy metabolism via different metabolic pathways. However, the metal pollution in GQ site mainly influenced the osmotic regulation in the oysters C. sikamea. This study demonstrates that NMR-based metabolomics is useful to characterize metabolic responses induced by metal pollution.
