Cereal industry and its derived products have a big economic and social importance worldwide. Therefore, as wheat flour is a commodity for all bread and bakery industry, it is safety is of high nutrition and toxicological interest. In this investigation we intend to study and determine the content of twelve metals in 50 samples of wheat flour coming from a wheat flour industry. Macro elements s...

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 effects of trace metal contaminants (lead, cadmium, and mercury) on the immunologic responses of rats infected with Trypanosoma lewisi were investigated to determine whether chronic exposures to subclinical levels of these metals have adverse effects on the host's ability to respond to an infective agent.Earlier and higher levels of parasitemia were detected in animals exposed to cadmium, l...

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 lower ser...

A preconcentration/separation procedure is presented for the solid phase extractionof trace cadmium and lead ions as their 2-propylpiperidine-1-carbodithioate (PPCD) chelates inenvironmental samples on Nano Graphene, prior to cadmium and lead determinations by atomicabsorption spectrometry. The preconcentration procedure was optimized by using model solutionscontaining c...
