“…The sensitivity of crustaceans to metals is well documented, and the importance of shrimp for environmental monitoring studies as bioindicators of metal pollution has been emphasized by several investigators (Larsson et al 1985;Yusof et al 2004;Yilmaz and Yllmaz 2007). In the present study also, on comparing the metals concentration in the fish and shrimp species it can be easily conjectured that irrespective of the locations, the shrimps accumulated more metals than the fish species.…”

Concentrations of Cd, Cu, Pb, Ni, Zn and Cr were estimated using inductively coupled plasma-mass spectrometry in sediment, water, fish and shrimp collected from the Subarnarekha River. Fish species Mystus gulio, Puntius conchonius, Labeo calbasu, Labeo rohita and Labeo bata, while the shrimp species Penaeus indicus, were used for the study. The range of Cd, Cu, Pb, Ni, Zn and Cr in all the samples was found to be 0.004-0.85, 0.75-145.2, 0.03-0.41, 1.25-21.5, 12.4-109.5 and 0.22-11.36 mg kg -1 fresh, respectively. The concentrations of metals in the fish and shrimp exceed the limits of Indian and international standards for food for Cu, Ni, Cd and Zn in some samples. Higher concentrations of the metals were observed in the shrimp as compared to fish samples. The calculated daily intakes of the metals through the consumption of fish and shrimps ranged from 0.30 to 27.0 % of the corresponding tolerable limits suggested by the Joint FAO/WHO Expert Committee on Food Additives. The mean target hazard quotient values for the 6 metals were below 1 for all the samples; however, the maximum was more than 1 for shrimp Cu and Cr. The results indicated that the concentration of the metals in shrimps at some locations was alarming and pose an appreciable hazard risk on human health. Potential ecological risk analysis of sediment indicated that most of the sites posed moderate ecological risk with Cd posing a considerable risk at all the sites.

“…Due to toxic nature of certain heavy metals, these chemical constituents interfere with the ecology of a particular environment and on entering into the food chain they cause potential health hazards, mainly to human beings. It was reported by several workers that the discharge of heavy metals into the sea through rivers and streams results in the accumulation of pollutants in the marine environment especially within shrimps (Yusof et al 2004). Thus shellfish and shellfish products can be used for monitoring potential risk to humans because these are directly consumed by a large population (Subramanian and Sukumar 1988).…”

Heavy metals are dangerous to aquatic organisms and it can be bioaccumulated in the food chain leading to diseases in human. Cumulative effects of metals or chronic poisoning may occur as a result of long-term exposure even to low concentrations. The accumulation of heavy metals varies depending upon the species, environmental conditions, and inhibitory processes. Concentrations of zinc, copper, lead, and cadmium were determined in finfish and shellfish species in the Gangetic delta using a PerkinElmer Sciex ELAN 5000 ICP mass spectrometer and expressed as milligrams per kilogram of dry weight. In finfish and shellfish species the concentrations of Zn, Cu, Pb, and Cd were comparatively higher at stations 1 and 2 than the permissible level of WHO. The concentration of metals exhibited significant spatial variation and followed the order station 1 > station 2 > station 3 > station 4, which may be related to different degree of contamination in different location. The metal accumulation exhibited species specificity.

Five fish species and one shrimp species from the Subarnarekha river were analyzed for heavy metals using inductively coupled plasma-mass spectrometry. The geometric mean concentration of As, Cd, Cu, Fe, Pb, Ni, Zn, Cr, Co, and Sr for all the samples was found to be 0.248, 0.031, 5.16, 104.9, 0.121, 4.68, 52.2, 0.784, 0.207, and 42.86 mg kg(-1)fresh, respectively. The concentrations of metals in the fish and shrimp exceed the limits of Indian and FAO standards for food for As, Cu, Ni, Cd, and Zn in many samples. The mean target hazard quotient (THQ) values for the 10 metals were below one for all the samples; however, the maximum THQ was more than one for shrimp in case of As, Cu, and Cr. The results indicate that the concentration of metals in some species, especially shrimp, at some locations is alarming and do present an appreciable hazard risk on human health.
