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...

OBJECTIVE To measure the concentrations of the trace elements lead and cadmium in human placenta and in maternal and neonatal (cord) blood. To assess the influence of the strongly polluted environment on the content of metals in tissues and on the permeability of placenta to cadmium and lead. Various methods of mineralisation were tested before analysis. METHODS Graphite furnace atomic absorp...

A brief review of the literature indicates that nutritional deficiencies have been shown to increase the absorption and toxicity of orally ingested lead and cadmium. Results from recent studies indicates that low level oral ingestion of cadmium and lead perturbs the metabolism of zinc, copper, and iron and that these changes may be the earliest manifestation of the toxicity of lead and cadmium....

Background: Lead and cadmium are toxic heavy metals found as major contaminants in food products and edible oils. The aims of this study were to investigate the lead and cadmium contaminations in seeds and extracted oils from Brassica napus L and Carthamus tinctorius grown in the vicinity of industrial sites (Isfahan Zobe Ahan) near Isfahan province/Iran. Methods: In this study, the seeds of B...

Environmental cadmium and lead exposures are widespread, and both metals are nephrotoxic at high exposure levels. Few studies have evaluated the associations between low-level cadmium and clinical renal outcomes, particularly with respect to joint cadmium and lead exposure. The geometric mean levels of blood cadmium and lead were 0.41 lg/L (3.65 nmol/L) and 1.58 lg/dL (0.076 lmol/L), respective...

BACKGROUND Lead and cadmium are harmful heavy metals that are used for a variety of occupational purposes. Considering their potentially hazardous effects on health, studies on the association between exposure to these two heavy metals and health disorders have been actively conducted. This study aimed to determine the association between blood lead and cadmium levels and blood pressure in work...

according to various pollution sources, have adverse effects on the health of ecosystems in a region, it is important to estimate the amount of contamination in the area. in this study, concentrations of ni, cd and pb in the soft tissues of the bivalve saccostrea cucullata were examined at 4 ages categories and 3 longth categories in beaches loft port by icp-oes. the results showed that the mea...

background: blindness due to cataract is a major and important problem in pakistan. the problem is expected to increase in future due to increase in tobacco smoking. the aim of study was to look for the mechanism associated with metal deposition and its effect on antioxidant enzymes in lens of smokers in karachi, pakistan. methods: 20 cataract patients were randomly selected from out patient de...

this study aimed to evaluate regional soil borkhar of the metals lead and cadmium has been made. in this field study fires visits to the regions. the limit of this study located in the east refineries, petrochemical and power plant to 20 km was selected. the 41 soil samples from depths of 0 to 10 cm in area and were randomized. soil samples were transported to the laboratory and by air was dry ...
