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...

aims: heavy metals in the environment are toxic to plants, animals and human. this study aimed to investigate concentration of arsenic, lead and cadmium in iranian and non-iranian rice which have been sold in kashan city, iran shops.  materials & methods: in this cross-sectional study, 126 samples from 42 trademarks (15 iranian and 27 non-iranian) rice were collected from kashan shopping center...

background: cold-induced aggregation micro extraction based (ciame) based on ionic liquid was used as a rapid and simple method for determination trace amounts of cadmium and lead in milk powder by analysis with flame atomic absorption spectrometry (faas). methods: sample solution containing of cd2+ and pb2+ in dynamic range, phosphate buffer (ph = 9, 3 ml), diethyl dithiocarbamate (complexing ...

hydrographically bolivian poopó lake is located in the basin of desaguadero river and it has over a dozen main tributary rivers and other smaller rivers with lower flow. the mine water discharge from the abandoned and current mining activities polluted these rivers by carrying heavy metals, dissolved and suspended solids which in turn polluted the poopó lake which is considered as an important ...

Background & Aims of the Study: Heavy metals contaminate drinking water, air and soils. It is very harmful for humans and other live organisms. Phytoremediation is one of the direct bio-remediation methods for heavy metal removal from polluted water and soils. This method is accepted environmentally, economically and aesthetically. The purpose of this study was to assess Tamari...

we determined the concentrations of lead and cadmium in edible parts of colocasiaesculenta,amaranthusspp. and ipomoea batata cultivated on farms in industrially polluted sections of nyabugogomarsh (kigali, rwanda) and quantified metal intake by consumers of these crops. we report that metalconcentrations in crops were within eu limits. the highest metal concentrations were found in amaranthussp...

the effects of cadmium and lead on human erythrocyte acetylcholinesterase activity were studied. blood used in this study was obtained from 24 healthy individuals, then after hemolysation, treated with 3 various concentrations of cadmium and lead. a strong inhibition of acetylcholinesterase was noted in treated samples by cadmium and lead. the remaining activity in the case of lead, the remaini...
