Lead contamination in fishes of the Kor River
Lead concentration in muscle, liver, kidney, brain and gonad tissues of two cyprinid fishes, Cyprinus carpio and Copoeta spp., from three sections of the upper, middle and lower parts of the Kor River was evaluated in 2006. Totally 225 specimens were caught for this purpose (75 specimens from each zone). Tissue samples were digested in acid and their lead concentrations were assayed by ICP meth...

متن کاملLead Contamination in Cocoa and Cocoa Products: Isotopic Evidence of Global Contamination
In this article we present lead concentrations and isotopic compositions from analyses of cocoa beans, their shells, and soils from six Nigerian cocoa farms, and analyses of manufactured cocoa and chocolate products. The average lead concentration of cocoa beans was </= 0.5 ng/g, which is one of the lowest reported values for a natural food. In contrast, lead concentrations of manufactured coco...
متن کاملConsumer Food Handling Practices Lead to Cross - contamination
Consumers engage in food handling practices that can contribute to foodborne illness, and there is interest in improving those behaviors. The purpose of this study was to determine the impact of the “Food Safe Families” clean and separate messages on cross-contamination behaviors of consumers and to determine the impact of external safe food handling cues. Participants (n = 123) were randomly a...
متن کاملFurther evidence of lead contamination of Omaha skeletons.
A previous analysis of Omaha skeletons dating between A.D. 1780 and 1820 revealed the presence of lead in all skeletons with high concentrations in children and adult males (Reinhard and Ghazi [1992] Am. J. Phys. Anthropol. 89:183-195). Two likely explanations for the high lead levels were presented: 1) metabolic absorption of lead and 2) diagenetic uptake of lead by the bones from postmortem a...
