“…Trash fish and fish meals are mainly used for marine fish farming, which usually contribute to fecal mass and food residues, and raise the loading of heavy metals (Chang and Chen, 2006;Mai et al, 2006). Deteriorations of sediment quality around fish farming zones have been reported in several studies (Wong et al, 2001;Zhang et al, 2007;Meng et al, 2008;Yu et al, 2008;Qiu et al, 2011). Pollution of marine sediment in aquacultural zones and the subsequent bioaccumulation of heavy metals pose a potential risk to the public health (Dural et al, 2007;Man et al, 2010).…”

“…1), contaminated oysters C. hongkongensis were collected from the Baijiao (BJ, 24°28 0 2 00 N, 117°56 0 19 00 E) and Fugong (FG, 24°22 0 58 00 N, 117°54 0 13 00 E) sites, along the contaminated Jiulongjiang estuary, and the control oysters were collected from the harbor of the Jiuzhen (JZ, 24°2 0 38 00 N, 117°42 0 26 00 E) site, from the nearby relatively clean Jiuzhen estuary, Fujian, China,. Evidence confirmed that the Jiulongjiang estuary was contaminated by metals (Liu and Wang, 2012;Zhang et al, 2007). This estuary is an important area for oyster culture, and the average surface salinity ranges from 14 to 26 psu depending on the tidal action (Liu and Wang, 2012).…”

H NMR a b s t r a c tMetal pollution has been of great concern in the estuaries in Southern China. In this study, metabolic differences between oysters Crassostrea hongkongensis from clean and metal-polluted sites were characterized using NMR-based metabolomics. We collected oyster samples from one clean (Jiuzhen) and two metal polluted sites (Baijiao and Fugong). The metal concentrations in oyster gills indicated that both the Baijiao and Fugong sites were severely polluted by several metals, including Cr, Ni, Cu, Zn, Ag, Cd and Pb. In particular, Cu and Zn were the major contaminants from the Baijiao and Fugong sites. Compared with those oysters from the clean site (JZ), metal pollution in BJ and FG induced disturbances in osmotic regulation and energy metabolism via different metabolic pathways, as indicated by different metabolic biomarkers. This study demonstrates that NMR-based metabolomics is a useful tool for characterizing metabolic responses induced by metal pollution.

“…The TOC varied between 1.2 and 3.9, with high values in the west and east parts and lower concentrations in the middle part of the study area. It has been widely reported [19,41,42] that there is heavy metals uptake by the organic carbon content of sediments. Organic content is recognized as a useful tool to obtain quantitative and qualitative information from both absolute values and variation trends; it comes from natural and anthropogenic sources, and even if it is not directly responsible for dangers to human health, [19] particulate organic materials have a high cation exchange capacity and strongly sequester metal ions.…”

This study concentrates on the speciation and distribution patterns of some heavy metals (Pb, Ni, Cd, Zn, and Cu) in surface sediments in the southern part of the Caspian Sea, the biggest lake in the world, to obtain an overall classification for the origins of metals in the area using a sequential extraction technique. At all sampling stations, Pb, Ni, Zn, and Cu were mostly (>50%) accumulated in the resistant fraction, which indicated that there were no significant anthropogenic inputs of Pb, Ni, Zn, and Cu into the surface sediments of the south Caspian Sea. Guilan province on the west coast of Caspian Sea accumulated higher percentages of non-resistant fractions of Pb and Zn, while Mazandaran and Golestan provinces in the middle and western parts of the Caspian Sea, in the Iranian zone, accumulated higher percentages of non-resistant fractions of Ni and Cu. The present study revealed that the coastal area of the south Caspian Sea is still not seriously contaminated. Cadmium in Guilan and Golestan provinces were dominated by non-resistant fractions (55-69%), which indicated more anthropogenic inputs of Cd on the south coast of the Caspian Sea in comparison with other metals.
