Hemodialysis is being implicated in the development of metabolic disturbances, as complications have been observed and the role of trace metals in their development has been questioned. In 78 renal failure patients who underwent hemodialysis, serum levels of zinc and copper were determined before and after first hemodialysis. Acute and chronic renal failure patients were found to have lowe...

Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...

The purpose of this study is to characterize native bee plants regarding their capacity to extract and accumulate trace elements from the soil and its consequences to the sanity of the produced pollen. The trace elements Cu, Mn, Pb and Zn were analyzed in soil, plants and bee pollen from Teresina region (PI), Brazil, by flame atomic absorption spectrophotometer. Considering the studied plant sp...

During 2003, the U.S. Geological Survey established a major long-term water-quantity and qualitymonitoring network for the City of Atlanta (COA). During 2004 and 2005, suspended sediment fluxes from the COA to downstream receiving waters amounted to about 150,000 t y; ≥94% of the transport occurred in conjunction with stormflow, which also accounted for ≥65% of the annual discharge. This occurr...

The alteration of hydrologic condition of Three Gorges Reservoir (TGR) after impoundment has caused numerous environmental changes. This study investigated the distribution, accumulation and potential sources of the seldom monitored trace elements (SMTEs) in sediments from three tributaries (ZY, MX and CT) and one mainstream (CJ) in TGR during different seasons. The average contents of most SMT...
