“…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.).

“…Dı´az-Asencio et al (2009) also reported a significant enrichment of mercury in the estuary sediment in recent years, reaching a maximum level of 2.68 mg.g x1 around 1990. Moreover, Olivares-Rieumont et al (2012) found levels of mercury ranging from 0.190 to 0.690 mg.g x1 dry weigh (dw) in oyster tissues (Crassostrea rizophorae) collected at the Sagua la Grande River estuary and offshore mangrove keys 19 km downstream of CAP.…”

-This study first reports concentrations of arsenic (As) and selenium (Se) in fish tissue of Clarias gariepinus from Sagua la Grande River in the Villa Clara Province, Cuba. We also confirm the mercury (Hg) levels in these fish obtained previously. Individuals were captured in three areas near Sagua la Grande City, where this fish is a common source of food for the city inhabitants. Concentrations range of As, Hg and Se (in wet weight) were 0.01-0.11 mg.g x1 ; 0.03-0.24 mg.g x1 and 0.75-3.87 mg.g x1 , respectively. As and Se levels were positively correlated (n = 19, r = 0.673, P < 0.05). High levels of Se were found in fish tissue and in 31.6% (n = 6) of individuals captured exceeded the threshold value for Se toxicity, which means that Se is likely to produce adverse consequences on the fish themselves or on the wildlife organisms that eat them. As and Se concentrations were positively correlated with fish weight and length (P < 0.05). Fish from irrigation canal have higher Se concentrations than fish captured in the other two stations. However, no significant differences were found between Hg and As concentrations in fish at the three sampling stations. Finally, as the Se concentrations in C. gariepinus were abnormally high, we suggest the need for studies about Se sources in the zone, the effect of Se in fish and the intake associated with fish consumption.
