“…Oneway analysis of variance (ANOVA) and post-hoc least significant difference tests followed by correlation analysis (bivariate correlations) were used to extract information from the chemical analysis in order to find out the relationships among the trace elements (Capelli et al, 2000;Szefer et al, 2002). In this work, the results of chemical analysis were presented as mean7 SD.…”

a b s t r a c tOne hundred and fifty nine samples of nine edible bivalve species (Argopecten irradians, Chlamys farreri, Crassostrea virginica, Lasaea nipponica, Meretrix meretrix, Mytilus edulis, Ruditapes philippinarum, Scapharca subcrenata and Sinonovacula constricta) were randomly collected from eight local seafood markets in six big cities (Dalian, Qingdao, Rizhao, Weifang, Weihai and Yantai) in the northern coastal areas of China for the investigation of trace element contamination. As, Cd, Cr, Cu, Hg, Pb and Zn were quantified. The risk of these trace elements to humans through bivalve consumption was then assessed. Results indicated that the concentrations of most of the studied trace element varied significantly with species: the average concentration of Cu in C. virginica was an order of magnitude higher than that in the remaining species; the average concentration of Zn was also highest in C. virginica; the average concentration of As, Cd and Pb was highest in R. philippinarum, C. farreri and A. irradians, respectively. Spatial differences in the concentrations of elements were generally less than those of interspecies, yet some elements such as Cr and Hg in the samples from different cities showed a significant difference in concentrations for some bivalve species. Trace element concentrations in edible tissues followed the order of Zn4Cu 4As 4Cd 4Cr4 Pb 4Hg generally. Statistical analysis (one-way ANOVA) indicated that different species examined showed different bioaccumulation of trace elements. There were significant correlations between the concentrations of some elements. The calculated hazard quotients indicated in general that there was no obvious health risk from the intake of trace elements through bivalve consumption. But care must be taken considering the increasing amount of seafood consumption.

“…Multivariate analysis methods such as one-way analysis of variance (ANOVA), principal component analysis (PCA), and correlation analysis (bivariate correlations) have been used to extract information from the chemical analysis in order to find the relationships among these heavy metals in organisms (Foster, 1995;Szefer et al, 1998Szefer et al, , 1999bSzefer et al, , 2002Holmes et al, 1998;Lucila Lares et al, 2002;Capelli et al, 2000;Kim, 1995).

Mollusks living in seas can accumulate heavy metals, and may serve as excellent passive biomonitors. During a period of 1 year, bioaccumulation of As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn was examined in nine kinds of mollusks (Rapana venosa, Neverita didyma, Scapharca subcrenata, Mytilus edulis, Amusium, Crassostrea talienwhanensis, Meretix meretrix, Ruditapes philippinarum, and Mactra veneriformis), which were collected at eight coastal sites along the Chinese Bohai Sea. Metal concentrations were directly determined by inductively coupled plasma mass spectrometer (ICP-MS). Two certified reference materials, dogfish muscle (DORM-2) and mussel (GBW 08571), were used to validate the methods, and the recoveries were within 83.72 -112.30% of the certified values. Bioaccumulation of metals varied strongly among sampling sites and species. Statistical analysis (one-way ANOVA) indicated that different species examined showed different bioaccumulation of metals, and perhaps they could be used as potential biomonitors to investigate the contamination levels of heavy metals. Principal component analysis (PCA) and correlation analysis were used to study the relationships between these heavy metals. The results showed that, in nine mollusks' tissues, there are significant correlations between these elements in adjacent main group or subgroup in periodic table of elements. D

“…Several animal species have been suggested to be suitable for the monitoring of environmental pollution. Mussels (Dreissena polymorpha) (Binelli et al, 2001;Szefe et al, 2002); herrings (Clupea harengus), and partridges (Alectoris rufa) (Herrera et al, 2000) or even mammals such as cattle (López-Alonso et al, 2002) and fox (Corsolini et al, 2000) have been suggested for the monitoring of environmental pollution. Since 1970, honeybees (Apis mellifera) have increasingly been used to monitor heavy metal environmental pollutants as reported in some studies (Porrini et al, 2002;Bromenshenk et al, 1985).…”

S u m m a r yThe aim of this study was to determine the levels of these elements: Hg, Ba, Ca, Fe, Mn, Li, As, Na and K in the bodies of bees. Honeybee samples were randomly collected from apiaries located in four counties of the province of Kurdistan. The four counties were: Marivan, Bijar, Kamyaran and Ghorveh. The data obtained from this study showed that K had the highest concentration, followed by Na, Ca, Hg, Ba, Fe, Mn, Li and As. From among all the sites, there were no signifi cant differences recorded between the concentrations of the different metals. The results did show that three minerals groups were able to be differentiated: elements that were very abundant, elements in a medium concentration, and trace elements. The fi rst group consisted of K and Na, with a range from 41.857 to 47.871, and 12.653 to 16.183 ppm, respectively. The second mineral group was composed of Ca, Hg, Ba, and Fe, where Ca was the most abundant element (with a range of 9.077 to 10.058 ppm), followed by Hg (1.12-4.786 ppm), Ba (2.881-3.481 ppm), and Fe (1.050-1.727 ppm). The third mineral group was composed of Mn, Li and As. They ranged from 0.262 to -0.399, and from 0.043 to 0.101, and from 0.017 to 0.068 ppm, respectively.
