“…And there is a little different in tilapias, the concentrations of Co and V in the heart were higher than in other tissues. The results suggested that heart can accumulate large amounts of Cu, and the gill can accumulate a lot of Ba, Co, Mn and V. This result partly are similar to the opinion reported by Skoric et al (2012), they found that gills had the maximum concentrations of Mn and Ba in studied species. The concentration of As in different tissues were not significantly different in big-head carps and grass carps (p [ 0.05), while in carps and tilapias, the contents of As are similar among the four tissues.…”

“…The maximum concentration of As in the muscle of tilapia reached 420.32 lg/kg, which was approximately ten times higher than in the other three fishes in this study. The copper contents in fish muscle this area were comparable with that in other areas (Xie et al 2010;Türkmen et al 2005;Skoric et al 2012). According to the national standards for maximum allowable levels of contaminants in foods (GB 2762-2005) and tolerance limit of copper in foods (GB 15199-94), the maximum allowable levels of contaminants (MLs) of Cr, As, Cd, Pb and Cu are 2.0, 0.1, 0.1, 0.5 and 50 lg/g in fish, respectively.…”

“…By comparing Tables 2, 3, 4, 5 and 6, 7, as concentrations were much higher in fish samples than water samples, and other heavy metals were comparable between water and fish samples, which might indicate the accumulation of As in fish. The concentrations of several toxic elements, such as Cr, Cd and Pb, in the muscle of the four fish species from Lhasa are apparently lower than those from other areas (Xie et al 2010;Türkmen et al 2005;Skoric et al 2012). The maximum concentration of As in the muscle of tilapia reached 420.32 lg/kg, which was approximately ten times higher than in the other three fishes in this study.…”

Fish is consumed as a common food by humans due to its nutritional and therapeutic benefits. However, they can accumulate toxic chemicals (such as heavy metals, persistent organic pollutants) from water and food chain. Very few studies have been investigated on heavy metal contents in fish from Tibetan Autonomous Region of China. In order to study heavy metals levels in fish from aquaculture farms and evaluate the risk that human consume fish in this area, we collected four types of aquaculture fish species (6 big-head carps, 5 grass carps, 5 carps and 5 tilapias) from fisheries around Lhasa city in this study. 9 heavy metals (Cr, As, Cd, Pb, Cu, Ba, Co, Mn and V) in different tissues of fish were determined by an inductively coupled plasma mass spectrometer. Cr, Ba, Co, Mn and V could easily accumulate in the gill, and Cu was detected in the hearts of all the fishes. Toxic metal (As, Cd and Pb) contents were higher in the liver than those in other tissues, heavy metal levels were the lowest in the muscle among all tissues. Most of heavy metal concentrations in the tilapia tissues were higher than those in other fish tissues, especially arsenic. Arsenic content in the tilapia samples was *2-4 times higher than the maximum levels (MLs) of contaminants in the national standard, and other metals were all lower than the MLs. Compared the estimated daily intake of heavy metals through fish consumption with tolerable daily intakes recommended by FAO, the metals daily intake of As, Cd and Pb from fish consumption might not pose serious health risk to the local inhabitants. It is therefore necessary to determine the dose level for human, which is considered to be taken daily over a lifetime without adverse effects.

20Concentrations of 10 trace elements (Hg, As, Cd, Pb, Co, Cr, Cu, Ni, Se and Zn) were determined 21 in different tissues (liver, kidney, muscle, heart and brain) of African sacred ibis (Threskiornis observed in the great white pelican compared to the other species, and liver concentrations of these 27 two elements showed positive correlations with trophic level. Concentrations of toxic elements (As,28 Cd, Pb and Hg) in liver were below their respective toxicological thresholds, indicating that the data 29 may provide baseline information for future studies. Trace elements are highly persistent, have bioaccumulation and/or biomagnification potential 34 along the food web, and depending upon their concentrations may be toxic to humans and wildlife. 35Owing to their wide distribution, feeding at different trophic levels and sensitivity to environmental (Carpenter et al. 2004;Heinz 1996). 3In general, effects of exposure to trace elements have been associated with declines in bird 4 populations [http://www.birdlife.org]. However, despite the presence of the great biodiversity and 5 numbers of birds, the African environment has received little attention from researchers in reference 6 to environmental contamination up to the present day. As a consequence, there is a paucity of 7 information about the contamination status and ecological impacts of pollutants like trace elements 8 in birds inhabiting Africa. Thus, monitoring levels of environment pollutants in avian species may 9 be of crucial importance in preventing potential risks to living beings. 10The Ethiopian Rift Valley comprises seven principal lakes in a closed water basin. It is a highly 11 productive agricultural region, and a major tourism attraction area for bird watching in the country. 12The region provides ideal habitat for a variety of avian species and wildlife. It serves as a breeding, 13and wintering ground, and as a migration stopover area for several resident and migratory bird 14 species. Lake Ziway is one of the best sites in Ethiopia to see a diversity of bird species such as Valley region. Thus, it is expected that the data generated here will serve as reference values and 23 baseline data for future studies. 24Therefore, this work was intended to (1) assess the bioaccumulation levels of 10 elements (Hg, 25 As, Cd, Pb, Co, Cr, Cu, Ni, Se, and Zn) in liver, kidney, muscle, heart and brain of four bird species, 26 and (2) investigate potential ecological risks in birds to delineate the bird species at risk. The 27 information will henceforth be highly useful for conservation research on avian species. 29 Materials and Methods 30Detailed information about the studied bird species is described elsewhere (Yohannes et al. for the assessment of isotopic ratio was described in our previous study (Yohannes et al. 2014). 18Statistical analyses were performed using JMP 9 (SAS Institute, Cary, NC, USA), and the level analyze relations between log-transformed liver concentrations of trace elements and δ 15 N. 26 Results and Discussion...

Trace elements are chemical contaminants that can be present almost anywhere on the planet. The study of trace elements in biotic matrices is a topic of great relevance for the implications that it can have on wildlife and human health. Penguins are very useful, since they live exclusively in the Southern Hemisphere and represent about 90% of the biomass of birds of the Southern Ocean. The levels of trace elements (dry weight) in different biotic matrices of penguins were reviewed here. Maps of trace element records in penguins were included. Data on exposure and effects of trace elements in penguins were collected from the literature. The most reported trace elements in penguins are aluminum, arsenic, cadmium, lead, mercury, copper, zinc, and manganese. Trace elements have been measured in 11 of the 18 species of penguins. The most studied biotic matrices are feathers and excreta. Most of the studies have been performed in Antarctica and subantarctic Islands. Little is known about the interaction among metals, which could provide better knowledge about certain mechanisms of detoxification in penguins. Future studies of trace elements in penguins must incorporate other metals such as vanadium, cobalt, nickel, and chromium. Data of metals in the species such as Eudyptes pachyrhynchus, Eudyptes moseleyi, Eudyptes sclateri, Eudyptes robustus, Eudyptes schlegeli, Spheniscus demersus, Spheniscus mendiculus, and Megadyptes antipodes are urged. It is important to correlate levels of metals in different biotic matrices with the effects on different species and in different geographic locations.
