“…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.

“…Exoskeletal Co accumulation correlations of male specimens were especially similar to those of Cu, Ni, 52 Cr, and As in the same tissue. It is still unclear whether Ni is an essential metal for crayfish (Khan and Nugegoda 2003;Yilmaz and Yilmaz 2007). Essential or otherwise, Ni is toxic above a certain threshold and was the only tested metal to correlate with the essential metal Mn.…”

The present work details the analysis of heavymetal and metalloid concentrations in exoskeleton, gill, hepatopancreas, and abdominal muscle tissues of 60 crayfish (Astacus leptodactylus) specimens collected from Lake Hirfanlı, a dam lake located in Kırşehir (Turkey) with a low metal-contamination profile. [Pb]) and a metalloid (arsenic [As]) were measured by inductively coupled plasma-mass spectrometry, and the relative frequencies of the most abundant isotopes of Cr, Cu, Ag, Cd, Hg, and Pb were evaluated. Three correlation trends were evaluated between the following: (1) different elements in the each individual tissue, (2) individual elements in different tissues, and (3) different elements in different tissues. In addition, correlation rates of growth parameters (weight, cephalothorax length, and total length) with heavy-metal and metalloid concentrations in each tissue were investigated. Our results suggest that substantial differences in metal and metalloid-accumulation levels exist between male and female specimens, with stronger correlations between the heavy-metal concentrations observed in the male cohort. It is notable that correlation trends of Co, Cu, 52 As, Cr, and Ni in exoskeleton of the male specimens display strong similarities. Likewise, a very strong correlation is present in Ni-Cd and Ni-Pb accumulations in abdominal muscle of the male specimens; a similar trend is present between Cd and Pb concentrations in the same tissue of female specimens. For correlation rates of different heavy metals and metalloid in different tissues, the strongest positive association observed was between 63 Cu in gill and As in hepatopancreas, whereas the strongest negative correlation was between accumulated Ni in abdominal muscle and As in exoskeleton. Strong correlations between metals and metalloid accumulations were observed between exoskeleton and gill. In many cases, metal and metalloid accumulation was negatively correlated with growth parameters. Preferential accumulation of Cr and Cu isotopes was observed in different tissues, suggesting that significant amounts of isotope fractionation occur during heavy-metal accumulation. Relatively low correlation rates were observed between 52 Cr/ 53 Cr and 63 Cu/ 65 Cu concentrations in several tissue types in both male and female cohorts, whereas no such trend was observed between Cd and Pb isotopes.

“…Unlike in OM sources, trace metal concentrations of invertebrates and fish did not show any clear spatial pattern. Trace metal accumulation in biota appears to be highly variable in relation to several biotic and abiotic factors: metal species (Luoma & Rainbow 2005), trophic level or guild (Barwick & Maher 2003), size, season and sex (Al-Yousuf et al 2000, Yilmaz & Yilmaz 2007. The de toxification capacity of a species in relation to different trace metals is also highly variable (Amiard et al 2006).…”

Transitional environments are vulnerable interface systems, ecologically connected with adjacent systems by several biotic or abiotic flows. The coastal system of the Marinello ponds (Tyrrhenian Sea, Italy) is affected by a colony of yellow-legged gulls Larus michahellis (Naumann, 1840), resident on the cliff beside the ponds. To investigate the role of the gull colony as a potential source of allochthonous non-essential trace metals (As, Cd, Pb and total mercury, THg) and the consequent metal trophic transfer to the biota in the ponds, we collected guano, surface sediment and biota from 3 ponds with different levels of avian input. The highest concentrations were observed in guano and surface sediment of the seabird-influenced pond, suggesting that trace metals have undergone biotransport mediated by seabirds. To test for biomagnification, the trophic pathways of the ponds were first identified by δ
