Background The goal of our study was to evaluate the effects of different medicinal herbs rich in polyphenol (Lemon balm, Sage, St. John’s wort and Small-flowered Willowherb) used as dietary supplements on bioaccumulation of some essential metals (Fe, Mn, Zn and Cu) in different chicken meats (liver, legs and breast). Results In different type of chicken meats (liver, legs and breast) from chickens fed with diets enriched in minerals and medicinal

Background: The aim of this study is to measure the levels of heavy metals (Fe, Mn, Zn, Cu, Ni, Cd and Pb) found in common vegetables (parsley, carrot, onion, lettuce, cucumber and green beans) grown in contaminated mining areas compared with those grown in reference clear area and to determine their potential detrimental effects via calculation of the daily metal intake (DImetal) and Target Hazard Quotients (THQ) for normal daily consumption of

It was analyzed the water content of three pollen samples from three different sources, using the classical chemical method (Karl Fischer). It is very important for this method to select the proper work conditions because pollen has a complex composition. For Karl Fischer
s method we selected the most adequate solvents, temperature and particle size. The Karl Fischer titration in a mixture of solvents (Hydranal
solvent and n-octanol) at high temperature

Abstract: This study aims to determine the principal electrochemical characteristics of the electrodeposition of cerium metal from molten fluoride systems. The cathodic process of Ce3+ ions in LiF-NaF and LiF-NaF-CaF2 molten salts was studied using electrochemical techniques as steady state and cyclic voltammetry methods. The decomposition potential (Ed) and the overvoltage(
