Analysis of zinc (In) cadmium (Cd), lead (Pb) and copper (Cu) in drinking and irrigation waters by potentiometric stripping analysis (PSA) is described. The pH and EC of waters were also determined. The results for zinc and copper were compared with those obtained by atomic absorption spectrophotometry (AAS) which indicated a significantly (P<0.01) strong correlation (r = 0.994 and 0.984 for In...

DETERMINATION OF Cd AND Pb IN FUEL ETHANOL BY FILTER FURNACE ELECTROTHERMAL ATOMIC ABSORPTION SPECTROMETRY. A method was developed for quantification of Cd and Pb in ethanol fuel by filter furnace atomic absorption spectrometry. Filter furnace was used to eliminate the need for chemical modification, to stabilize volatile analytes and to allow the application of short pyrolysis step. The determ...

In this study the levels of cadmium and lead in blood and urine were measured by the method of graphite furnace atomic absorption spectrometry in 356 healthy, non-occupationally exposed individuals and the factors affecting the metal concentrations were investigated. The geometric means for cadmium in blood and urine were 0.98 microg/l (Cd-B) and 0.87 microg/gCr (Cd-U). The lead levels were 32....

The use of constructed wetlands for wastewater treatment has been proposed as an intermediate technological solution for handling wastewater. The aim of the study was to assess the efficiency of a constructed wetland at Egerton University, Kenya for heavy metals removal from wastewater. The wetland has been used for tertiary treatment of effluent from waste stabilization ponds system since 2007...

Wheat flour is an important source of nutrient and as such is widely consumed in most part of the world, as bread and other pastries. Due to its high consumption, the presence of heavy metal at high concentration would be a significant health risk. Based on the soil in which the wheat was grown and the milling technology employed in making the flour, the heavy metal content of wheat flour varie...

Alexander, F. W., and Delves, H. T. (1972). Archives of Disease in Childhood, 47, 446. Deaths from acute lead poisoning. The three fatal cases of acute lead poisoning described show the difficulty experienced in reaching an early diagnosis of lead intoxication. A rapid micromethod is now available for the determination of whole blood lead levels on small samples of blood, using atomic absorptio...
