Determination of Br, Ca, Cl, Co, Cu, I, K, Mg, Mn, Na, Rb, S, Ti and V in Cereals, Oils, Sweeteners and Vegetables Sold in Canada by Neutron Activation Analysis

Study of nutrients and toxic minerals in rice and legumes by instrumental neutron activation analysis and graphite furnace atomic absorption spectrophotometry

“…In the rice group, the tendency of values of trace elements in this study was K > Mg > Zn > Mn > Cl > Al > Br, in Canada (Soliman and Zikovsky, 1999) was K > Mg > Cl > Ca > Br > Cu > Mn > V > I, in India (Balaji et al, 2000) was Mg > K > Al > Ca > iron > Mn > Zn > Br > Cl, in India (Singh and Garg, 2006) was K > Cl > Ca > iron > Mn > Zn > Br > Cr > Se, and in Japan (Tsukada et al, 2007) was K > Mg > Cl > Ca > Zn > Mn > Al > iron > Cu and values of Cr, I, Mo, Se and V were lowest. The data showed that amounts of minerals were different depending on many factors such as sources and species of rice.…”

“…They were then analyzed along with the unknown Table 3 Mineral and toxic element contents in rice and legume samples (mean AE SD) (n = 6). Canada (Soliman and Zikovsky, 1999) India (Balaji et al, 2000) Paddy (O. sativa)…”

“…The sample preparation procedures for INAA (instrumental neutron activation analysis) are minimized by using a high efficiency and high resolution gamma spectrometer. This technique also offers an advantage as a non-destructive method (Soliman and Zikovsky, 1999;Howe et al, 2005). INAA is a suitable method for determination of various elements.…”

Composition and Daily Intakes of Some Trace Metals from Canned Beers in Nigeria

“…The knowledge of concentrations of trace metals in food is of significant scientific interest because some of these elements are essential for human health (e.g., Cu, Fe, Mn, Zn) while others, if present even at low concentrations, can be toxic (e.g., Cd, Pb, Hg, As) 11,14 . The socalled essential metals can be toxic depending on their concentration and speciation (e.g., Cr (III) is essential while Cr (VI) is toxic).…”

“…The socalled essential metals can be toxic depending on their concentration and speciation (e.g., Cr (III) is essential while Cr (VI) is toxic). This knowledge is essential for the calculation of dietary intakes of essential metals and evaluation of human exposure to toxic elements 14 . Some of these metals, such as Cd and Hg, can injure the kidneys and cause symptoms of chronic toxicity including impaired kidney function, poor reproductive capacity, hypertension, tumour and hepatic dysfunction.…”
