“…Although their impact has no visible influence comparing to other pollutants, heavy metal pollution can cause long-term effects on ecosystems. The bioaccumulation of contaminants in the tissues and the organs of marine organisms has been extensively studied throughout the world and led to the adoption of the bioindicator concept for the environmental quality assessment (Bat et al 1999;Machado et al 1999;Yarsan et al 2007). …”

The aim of this study was to monitor the heavy metal contents and fecal pollution in Tapes decussatus (carpet shell clam) from Izmir Bay (Eastern Aegean). Bivalve mollusks were sampled on January, March, July, and October 2007 in the Izmir Bay. Izmir Bay is one of the great natural bays of the Mediterranean. Concentrations of heavy metals were determined in the clams from the different seasons. Fecal coliform densities were determined to evaluate the degree of water pollution and clams' microbiological accumulation of the classical microbial pollution indicators. The concentration of heavy metals in T. decussatus from Izmir Bay were Hg 0.044-0.13; Cd 0.026-0.24; Pb 0.38-1.2; Cr 2.3-3.7; Cu 6.4-8.4; Zn 56.0-81.8, and Ni 8.1-9.6 microg/g (dry weight). The maximum values were generally obtained in July and March except Ni. This study found that the levels of heavy metals except Cr in T. decussatus were below Spanish and European Communities legislations for shellfish as food. Microbial pollution indicators (heterotrophic bacteria and fecal coliform) were measured in T. decussatus. Maximum heterotrophic bacteria and fecal coliforms were recorded in the winter while the lowest were detected in summer.

“…These metals may accumulate to a very high toxic level and cause severe impact on the aquatic organisms without any visible sign (Gupta et al 2009). Metals like Cu and Zn are essential elements and are carefully regulated by physiological mechanisms in most organisms, however, they are regarded as potential hazards that can endanger both animal and human health (Papagiannis et al 2004;Yarsan et al 2007), whereas others, such as Hg and As have no known roles in biological systems and can be toxic even at quite low levels (Canli and Atli 2003;Diaz et al 2006;Sprocati et al 2006).…”

Concentrations of copper, zinc, mercury, and arsenic were measured in the muscle, gill and liver tissues of Coreius heterodon and Pelteobagrus vachelli collected from the rare and endemic fish nature reserve in the upper reaches of the Yangtze River. The concentrations of copper and zinc in the tissues of these two fish species were higher than those of mercury and arsenic. Highest metal concentrations were generally found in fish samples from Yibin. The concentrations of copper, zinc, mercury, and arsenic in C. heterodon were higher than that in P. vachelli. The fish from this study area were not safe for human consumption.

“…It is well known that bivalves as filter feeding animals are able to concentrate heavy metals in their tissue; therefore they can be used for monitoring heavy metal pollution of the environment. Many authors use bivalve tissues for monitoring marine ecosystem health (Yarsan et al 2007;Olivares-Rieumont et al 2012;Shirneshan et al 2012).…”

This study measured the levels of total mercury (tHg) in the whole tissues of cockles (Anadara granosa and A. antiquata) harvested from three estuaries of Western Lombok Island (WLI), Indonesia. This paper also evaluated the hazard level posed by the mercury in relation to the maximum residual limit for human consumption and to estimate the weekly intake and compare it with the provisional tolerable weekly intake (PTWI). The tHg concentrations in A. granosa ranged from 0.020 to 0.070 mg kg(-1), and those in A. antiquata were between 0.032 and 0.077 mg kg(-1) at all locations. All samples of cockles harvested from WLI contain tHg below the permissible limit for human consumption. The maximum weekly intakes for total mercury by coastal people range from 0.28 to 1.08 µg kg(-1) b.w., and they are below the recommended values of PTWI (5.6 µg kg(-1) b.w.). If it is assumed that 100% of the Hg in cockles is methyl mercury (MeHg), consumption of the indicated amounts at the measured values wouldn't exceed the MeHg PTWI (1.6 µg kg(-1) b.w.).
