“…The concentration of trace metals indicates enrichment in the samples which are very close to the shore line in the study area indicate that higher concentration is due to the anthropogenic activities in coastal areas (Jonathan et al 2004). Moreover, it is also due to the recent development of industries and harbor activities (Hershelman et al 1981;Luoma and Phillips 1988;Fukushima et al 1992;Jonathan and Ram-Mohan 2003). In addition, the high values are also attributed to the continental input and runoff from the minor rivers that drain in this region (Muthuraj and Jayaprakash 2007).…”

The study of heavy metal distribution in coastal surface sediments is an important component in understanding the exogenic cycling as well as in assessing the effect of anthropogenic influences on the marine ecosystem. In this study, surface sediment samples were collected from five different traverses along the innershelf of Bay of Bengal, off Chennai, India during pre- and post-monsoon seasons. The results of Spearmen correlation matrix, factor and cluster analysis, enrichment and contamination factor analysis, and geoaccumulation index of the heavy metals analyzed in the collected surface sediment were discussed. The level of both enrichment and contamination factor are shown in following order Cd > Cu > Cr > Ni > Pb > Co > Zn > Mn > Fe > Hg. The geoaccumulation index suggests that Cd and Cu are strongly to extremely pollute the sediments in both seasons. The results strongly indict anthropogenic sources for moderate input of Cd and Cu in to the innershelf of Chennai coast.

“…In general, levels of all metals, except for Cd, in sediments for the Northern Aegean Sea, Greece (Fytianos and Vasilikiotis 1983), Pioneer Bay and Nelly Bay, Australia (Esslemont 2000) and the northern part of the Gulf of Suez, Egypt (El-Moselhy and Gabal 2004) are lower than the reported levels in this study. However, Singapore's marine sediments are still relatively uncontaminated with heavy metals when compared to available data for other countries including Thailand, Japan, Korea, Spain and China (Menasveta and Cheevaparanapiwat 1981;Fukushima et al 1992;Lee et al 1998;Morillo et al 2004;Guevara-Riba et al 2004;Yuan et al 2004).

Concentrations of heavy metals were determined in the water column (including the sea-surface microlayer, subsurface, mid-depth and bottom water) and sediments from Singapore's coastal environment. The concentration ranges for As, Cd, Cr, Cu, Ni, Pb and Zn in the seawater dissolved phase (DP) were 0.34-2.04, 0.013-0.109, 0.07-0.35, 0.23-1.16, 0.28-0.78, 0.009-0.062 and 0.97-3.66 microg L(-1) respectively. The ranges for Cd, Cr, Cu, Ni, Pb and Zn in the suspended particulate matter (SPM) were 0.16-0.73, 6.72-53.93, 12.87-118.29, 4.34-60.71, 1.10-6.08 and 43.09-370.49 microg g(-1), respectively. Heavy metal concentrations in sediments ranged between 0.054-0.217, 37.48-50.52, 6.30-21.01, 13.27-26.59, 24.14-37.28 and 48.20-62.36 microg g(-1) for Cd, Cr, Cu, Ni, Pb and Zn, respectively. The lowest concentrations of metals in the DP and SPM were most frequently found in the subsurface water while the highest concentrations were mostly observed in the SML and bottom water. Overall, heavy metals in both the dissolved and particulate fractions have depth profiles that show a decreasing trend of concentrations from the subsurface to the bottom water, indicating that the prevalence of metals is linked to the marine biological cycle. In comparison to data from Greece, Malaysia and USA, the levels of metals in the DP are considered to be low in Singapore. Higher concentrations of particulate metals were reported for the Northern Adriatic Sea and the Rhine/Meuse estuary in the Netherlands compared to values reported in this study. The marine sediments in Singapore are not heavily contaminated when compared to metal levels in marine sediments from other countries such as Thailand, Japan, Korea, Spain and China.

“…The content of Cd is lower than that of Tokyo Bay, Bay of Bengal and Red Sea (Jeddah, Radigh, Yanbu), similar with that of Diamond Harbor and SE coast of India, but is higher than that of Gulf of Manna and Southport; the content of Cr is lower than of Gulf of Manna, Bay of Bengal, Tokyo Bay and SE coast of India, but is higher than that of Southport, Diamond Harbor and Red sea (Jeddah, Rabigh, Yanbu); the content of Ni is lower than that of Bay of Bengal and Red Sea (Jeddah, Radigh, Yanbu), similar with that of Tokyo Bay and SE coast of India, but is higher than that of Gulf of Manna, Diamond Harbor and Southport; the content of Mn is lower than that of Tokyo Bay, but is higher than other bays. So, it can be inferred that the contamination level of Cd and Cr in surficial sediments of estuary in Daliao River and Yingkou Bay is low and the contamination level of Mn and Ni is high on the whole (Jonathan et al 2004;Fukushima et al 1992;Muthu and Jayaprakash 2008;Edward et al 2005;Santosh et al 2004;Stephenp-Pichanimani et al 2008;Nadia et al 2009). …”

Heavy metal pollution in the surficial sediments derived from estuary in Daliao River and Yingkou Bay is investigated in the present work in order to assess environmental quality and pollution levels. Physicochemical parameters of surficial sediments (sediment type and TOC) and the overlying water (temperature, EC, pH and dissolved oxygen) are also studied. The total concentrations of Cd, Cr, Mn and Ni in the samples are determined using inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). The result indicates the comparatively low concentrations of the four metals (the max. of 0.67 mg/ kg of Cd, 85.80 mg/kg of Cr, 1073.00 mg/kg of Mn and 38.62 mg/kg of Ni), the distribution rule of four metals in different regions of the studying area and the sources of the pollution. The methods of index of geoaccumulation, potential ecological risk index and pollution load index are used to assess the degree of contamination, distribution character and the sequence of pollution level in different regions which reflect the overall low values and low pollution level. The six-step sequential extraction method is used to determine the chemical forms of the four metals in order to evaluate their possible mobility, bioavailability and toxicity in surficial sediments. Cd and Mn are mostly concentrated in the CARB fraction, while Ni and Cr are mostly concentrated in the RES fraction. The mobility of the metals has the following order (average value):
