Evaluation of Trace Metal Levels in Surface Sediments of the Sergipe River Hydrographic Basin, Northeast Brazil
As distribuições de Co, Cr, Cu, Mn, Ni, Pb, Fe e Al foram investigadas em sedimentos superficiais coletados em 19 sítios da Bacia Hidrográfica do Rio Sergipe, Nordeste do Brasil. Foi definida uma base geoquímica para a região (RGB) usando o ferro como elemento de referência. Fatores de enriquecimento (EF) e índice de geoacumulação (Igeo) foram empregados para determinar a contribuição por orige...
متن کاملTrace Element Speciation and Behavior in the Tidal Delaware River
Measurements of dissolved As, Cr, Cu, and S~ using species-selective techniques were made in the tidal freshwater Delaware River at four sites in July 1991, January 1992, and March 1992. Concentrations of dissolved As, Cr, and Se were generally higher in July than in March or January. Copper concentrations were relatively constant. Both As and Cu increased in concentration in the region of Phil...
متن کاملAlterations in serum levels of trace element in patients with breast cancer before and after chemotherapy
Background: Breast cancer is the most common serious disease around the world. The trace elements have a vital role in the metabolism and chemotherapy may change the level of metal ions. Due to the ambiguity of the existence in this regard, the study examined the trace element serum levels in women with breast cancer before and after chemotherapy . Methods: Sixty patients were studied undergoi...
متن کاملTrace element levels in alopecia areata.
BACKGROUND Alopecia areata (AA) is a recurrent, nonscarring type of hair loss considered to be an autoimmune process. Though its etiopathology is not fully understood, there are claims that imbalance of trace elements may trigger the onset of AA. AIM The aim of the present study was to assess the levels of zinc, copper, and magnesium in the serum of AA patients. METHODS Fifty AA patients (3...
متن کاملTrends in chlorinated hydrocarbon levels in Hudson River basin sediments.
Analysis of sections from dated sediment cores were used to establish geographic distributions and temporal trends of chlorinated hydrocarbon contaminant levels in sediments from natural waters of the Hudson River basin. Radiometric dating was based primarily on the depth distribution of 137(Cs) in the cores and on the occurrence of detectable levels of 7(Be) in surface sediment samples. Eighte...
