“…Eventually they will fall down in the sediments; hence amounts of heavy metals in the sediments are often 10 to 100 times higher than those in surrounding water. In the sediments, these particles may be a serious derivative source of pollution, even after the main resource disappeared [14,15]. The effects of heavy metals on marine organisms can be divided into direct effects and indirect effects.…”

“…Although inputs were significantly reduced in 1986, heavy metals in sediments still show a remarkable gradient from high concentrations in the inner fjord (station S1) to background levels at the opening of the fjord (station S4) ( Fig. 1) (15,68). Mean metal concentrations determined in the total sediments of S1 in 2000 were, in milligrams per kilogram (dry weight), 60 for Cd, 100 for Cu, 800 for Pb, and 100 for Zn (15).…”

“…This fjord displays very high levels of heavy metals in the sediments, which are the result of the discharge of considerable amounts of Zn, Cd, and Pb (since 1920) by smelters located at the head of the fjord (15,61,68). Figures for 1980 indicated that 1,387 tons of Zn, 329 tons of Pb, and 14.6 tons of Cd were discharged into the fjord during that year alone (68). Although inputs were significantly reduced in 1986, heavy metals in sediments still show a remarkable gradient from high concentrations in the inner fjord (station S1) to background levels at the opening of the fjord (station S4) ( Fig.…”

Microbial community composition and structure were characterized in marine sediments contaminated for >80 years with cadmium, copper, lead, and zinc. Four sampling sites that encompass a wide range of sediment metal loads were compared in a Norwegian fjord (Sørfjord). HCl-extractable metals and organic matter constantly decreased from the most contaminated site (S1) to the control site (S4). All sampling sites presented low polychlorinated biphenyl (PCB) concentrations (⌺ 7 PCB < 7.0 ng g [dry weight] ؊1 ). The biomass ranged from 4.3 ؋ 10 8 to 13.4 ؋ 10 8 cells g (dry weight) of sediments ؊1 and was not correlated to metal levels. Denaturing gradient gel electrophoresis indicated that diversity was not affected by the contamination. The majority of the partial 16S rRNA sequences obtained were classified in the ␥-and ␦-Proteobacteria and in the Cytophaga-Flexibacter-Bacteroides (CFB) bacteria. Some sequences were closely related to other sequences from polluted marine sediments. The abundances of seven phylogenetic groups were determined by using fluorescent in situ hybridization (FISH). FISH was impaired in S1 by high levels of autofluorescing particles. For S2 to S4, the results indicated that the HCl-extractable Cu, Pb, and Zn were negatively correlated with the abundance of ␥-Proteobacteria and CFB bacteria. ␦-Proteobacteria were not correlated with HCl-extractable metals. Bacteria of the Desulfosarcina-Desulfococcus group were detected in every site and represented 6 to 14% of the DAPI (4,6-diamidino-2-phenylindole) counts. Although factors other than metals may explain the distribution observed, the information presented here may be useful in predicting long-term effects of heavy-metal contamination in the marine environment.

“…Testacean molluscs and echinoderms, with the organic material which is associated to the calcium carbonate of the shell, eliminate metals such as Fe, Co, Cr, Zn, Cd, Pb, and Hg (Auernheimer and Chinchon, 1997;Al-Mohanna and Subrahmanyam, 2001;Keteles and Fleeger, 2001). In the exoskeleton of starfish, the average life of Pb has been shown to be long (some years), while that of Cd is much shorter (Temara et al, 1998b).…”

This document shows the results obtained from a study on the concentration of toxic heavy metals in the internal tissue and exoskeleton of sea urchins, collected from their natural habitat. The levels of lead and cadmium were measured by Graphite Furnace Atomic Absorption Spectrometry. The mean concentrations of lead and cadmium in the internal tissue were 304.04 and 260.54 lg/kg respectively, whereas in the shell they were 185.02 and 142.48 lg/kg. We also performed a statistical analysis of the differences in the distribution of metals between their exoskeleton and their internal content, a correlation study of the metal content in internal tissue and shell and sampling areas, and a correlation study between the metal content and sample size. Since the sea urchin Diadema antillarum presents a wide range of variation in metal content, this study suggests that this species is an excellent bioindicator of heavy metal contamination. # 2009 Wiley Periodicals, Inc.
