“…However, when analyzed by blocks, it could be observed that there was no difference between A and B, but between A and C, and also between B and C. The average copper contamination from cold storage plant C was greater than those found in both A and B. this generated a significant difference when analyzed in group, however, no results were found to be above that permitted by the Australian legislation. Similar results were found in works on the analysis of Oreochromis mossambicus in reservoirs in the south of Sri Lanka (Allinson et al, 2002), and also in the analysis of Silurus glanis fillets from the Lake Sir Dam in Turkey (ERDOĞRUL; ERBILIR, 2007). The results for lead found in this paper differ from those found by Adeyeye et al (1996), where the analysis of Oreochromis niloticus muscles presented metal concentration on the ratio of 0.79 µg.g -1 .…”

“…Çoğun et al (2003) showed that Nilotic tilapias bioconcentrate cadmium when submitted to environments contaminated with the metal. Allinson et al (2002) analyzed Oreochromis mossambicus from reservoirs in the south of Sri Lanka, and found a contamination pattern similar to the one found in this study, only some individuals had the presence of cadmium in the analysis, with the suspicion that the metal was originated in the environment. Several factors influence the bioconcentration of metals.…”

“…Birungi et al (2007) exposed 240 samples of Nile tilapia to areas that were known to be contaminated in Lake Vitoria, Uganda, and after six weeks they found values of copper in the animals' muscles reaching concentrations of 10,000 µg Cu.g -1 muscle. Allinson et al (2002) collected Oreochromis mossambicus from reservoirs in the south of Sri Lanka and found a variation in the level of copper, in fillets from the fish, from 0.5 μg.g -1 to 1.2 μg.g -1 . Oyewale, Musa (2006) detected copper in Nilotic tilapia from the Kainji and Jeba lakes (Nigeria).…”

Determination of presence and quantification of cadmium, lead and copper in Nile tilapia (Oreochromis niloticus) fillets obtained from three cold storage plants in the State of Parana, Brazil Determinação da presença e quantificação dos metais cádmio, chumbo e cobre em filés de tilápia-do-Nilo (Oreochromis niloticus) obtidos de três frigoríficosAlexandre Nobuhiro TAJIRI 1 , Daisy PONTES NETTO 1 *, Márcia SASSAHARA 1 , Mari Sylmara Martins RODRIGUES 1 , Cristina Arduini Cavalcanti de ARRUDA 1 IntroductionThe name "Tilapia" is used to designate fish from the Cichidae family, Perciform Order (HUET, 1983), being commonly used as a reference to the genus Tilapia, Sarotherodon and Oreochromis, and mainly to the species of greater size and with potential for fishing, breeding and consumption .The most cultivated species of tilapia in the world is Oreochromis niloticus, commonly known as Nile tilapia or Nilotic tilapia (KUBITZA, 2000). This is a robust species, presenting high prolificity, resistance to high temperatures and low respiratory demand. It is also a plankton eater, omnivore and mouth brooding fish (BEVERIDGE; BAIRD, 2000; HUET, 1983; KUBITZA, 2000;OSTRENSKY;BOEGUER, 1998;POPMA; MASSE, 1999;TURNER;ROBINSON, 2000).The relevance of fish as a source of protein is undeniable, and so is its role as an indicator of environmental contamination. Fish are excellent sources for eco-toxicological studies due to their ability of removing, storing and bio-accumulating polluting composts in their organisms (STREIT, 1998).Nowadays, there are many contaminants being discharged into nature by human actions, and among these there are also toxic metals. Metals, among other criteria, can not be synthesized nor destroyed by men, and are released into the environment in geologic processes, such as rain, erosion and also ResumoA piscicultura é uma atividade econômica em pleno crescimento no Estado do Paraná/Brasil, sendo a tilápia-do-nilo (Oreochromis niloticus) uma das principais espécies de peixe cultivadas no Estado. A tilápia, além de ser um alimento rico, é um importante indicador de contaminação ambiental. O trabalho objetivou a análise dos filés de tilápia para averiguação de contaminação pelos metais cádmio, cobre e chumbo, e a comparação dos valores encontrados com legislações internacionais. Foram coletadas 135 amostras de filés de tilápia, entre julho de 2006 e maio de 2007, de três frigoríficos de peixe localizados nas regiões oeste e norte do Estado do Paraná. As amostras foram analisadas, utilizandose a espectrofotometria de absorção atômica, para averiguar a presença dos metais chumbo, cádmio e cobre. O chumbo não foi detectado nas análises. O cádmio foi detectado em três amostras, uma de cada frigorífico, nas concentrações de 0,012 µg.g -1 , 0,011 µg.g -1 e 0,014 µg.g -1 . O cobre foi detectado em todos os filés, sendo as médias de concentração de cada frigorífico de 0,122 µg.g -1 , 0,106 µg.g -1 e 0,153 µg.g -1 . As concentrações dos metais encontradas estão de acordo como o permitido pelas legislações europeias...

“…Another explanation for this phenomenon is that it is an issue of selection, where specimens with particularly high heavy-metal intake rates perished before attaining large sizes and only individuals that could mostly avoid metal accumulation survived to reach large sizes. A previous study by Allinson et al (2002) reported no correlation between length and As, Co, Cu, and Mn in gill of the Mozambique tilapia (Oreochromis mossambicus). Another study, performed by Cevik et al (2008) on Mediterranean mussel (Mytilus galloprovincialis), reported an overall lower strength of correlation between heavy metals accumulated in the same tissue compared with our study in addition to a smaller number of associations in general.…”

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.

“…This is probably because freshwater fishes are known to regulate constant internal metal concentrations (Henry et al 2004;Allinson et al 2002;Amundsen et al 1997). In fact, metal concentrations in a tissue depend on the specific metabolism of metal species in the tissue considered as well as the availability of the metal species in surrounding environment.…”

Concentration of V, Mn, Fe, Co, Cu, Zn, As, Se, Cd, and Pb in muscle, liver, and gill tissues of red tilapia (Oreochromis spp) sampled from three different aquaculture sites which include earthen pond, ex-tin mining pool, and concrete tank in Jelebu, Negeri Sembilan, were determined using microwave-assisted digestion-inductively coupled plasma-mass spectrometry. Accumulation patterns relating organs and elements, as well as origins and elements, were evaluated using multivariate statistics. With the aid of principal component analysis, it is possible to visualize the distribution pattern of metals in different organs as well as clustering tendencies of tilapia samples according to the production sites. In general, levels of V, Co, Fe, Cu, Zn, Se, and Cd in liver were higher than those in muscles and gills, whereas Mn and Pb were higher in gills while As in muscles. Results from principal component analysis revealed that there are similar pattern of metal distribution among organs regardless of the production sites. It is also suggested that Cu, As, and Pb are the best describers in characterizing the studied organs, where liver tissues are associated with high Cu, gills with high Pb, and muscles with high As. On the other hand, V, Co, and Pb are observed to be key discriminants for sample origins.
