Heavy Metals and Trace Elements in the Livers and Kidneys of Slaughtered Cattle, Sheep and Goats
Background: This study was performed to evaluate the levels of heavy metals in the livers and kidneys of cattle, sheep and goats from a mining region in the west of Iran. Methods: In this cross-sectional study, 90 samples were collected from the livers and kidneys of cattle (n=30), sheep (n=30) and goats (n=30) from a slaughterhouse in Hamedan City, western Iran. Lead, cadmium, manganese, zi...
متن کاملTrace Metals and Major Elements in Sediments of the Northern Persian Gulf
The concentrations of sixteen elements and organic carbon were determined in 78 marine sediment samples collected from the Iranian coastal waters of the Persian Gulf. Nine transects perpendicular to the coastline were sampled. Sixteen elements, including As, Ba, Cd, Co, Cu, Mn, Ni, Pb, Zn (trace metals) and Ca, Fe, Mg, Na, P, S, Si (major metals), were determined by Inductively Coupled Plasma M...
متن کاملDetermination and Application of Trace Elements
It is a well known fact that minera l plays an important role in the nutrition of animal and plant. The t race elements, which are a part of the mineral and exi st in a very small amount in the living bodies, include not only essential elements but also harmfu l and useless elements. In the researches up until now, physiological significance or essentiality for living body of such elements as c...
متن کاملTrace determination and separation of tin (II) by floatation-spectrophotometric using kalmagyte and CTAB
ABSTRACTA novel floatation-spectrophotometric extraction method was developed for the recovery of tin (II) from aqueous samples prior to determination by UV spectrophotometric detection. The method is based on the formation of a complex between tin (II) and kalmagyte in pH=8. The complex is floated in the interface of n-hexane and aqueous phases. After removing the aqueous phase, the floated pa...
