Current study was done to determine the concentration of heavy metals including Lead and Cadmium and nutrients element Copper and Zinc in a simple and whole wheat Macaroni in the valid different supermarkets in the city of Tehran. 254 samples from seven Iranian simple Macaroni , four foreign simple Macaroni and two Iranian whole wheat macaroni were purchased consecutively in 3 seasons of 2015. ...

background: since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. the aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of mercuric chloride (hgcl2), lead chloride (pbcl2) and zinc sulfate (znso4) pollutan...

A lead-zinc carbonate ore sample containing 2.5% Pb and 9.39% Zn was used in this research work. The sample was prepared from the Darreh-Zanjir mine located in the Yazd province (Iran). Influences of the influential factors on flotation of smithsonite and cerussite were investigated. Among the different parameters involved, dosages of the dispersant, depressants, sulfidizing agent, and collecto...

Background & Aims of the Study: The objective of this study was to investigate the seed pre-treatment with salicylic acid (SA) on tolerance and remediation ability of Brassica oleracea var. acephala under lead and zinc stresses. Materials and Methods: Present study was conducted to evaluate phyto-accumulative ability of Brassica oleracea var. acephala in heavy metal concentrat...

BACKGROUND Early childhood lead exposure is associated with numerous adverse health effects. Biomonitoring among susceptible populations, such as children, has not been previously conducted. The aim of the study is to evaluate the blood lead (Pb) and total blood calcium (Ca) levels; blood zinc (Zn) levels. METHODS A cross-sectional study was designed to collect healthy children age 1- 36 mont...

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...
