A microwave-assisted digestion method using diluted HNO3 was proposed for subsequent determination of Ca, Cd, Co, Cu, K, Mg, Mn, Mo, Na, P, Pb, S, V, and Zn in beans, basil, mint ICP OES flame photometry. After applying factorial design, the optimized conditions were an concentration 1 mol L-1, 2.5 mL H2O2, a time 20 min. The accuracy assessed seven reference materials, with statistical agreement between determined certified values RSD up to 11%. Linearity satisfactory (r > 0.999), limits...
This study determined the levels of total mercury in Spanish samples baby food, fast and daily meal, which people different ages consume, to evaluate potential toxicological risks through contribution tolerable intake (TDI). The concentrations were thirteen commercial foods for infants 6 12 months old, six types prepared children, nine canteen menus adults. Samples analyzed using a direct analyzer, following concentration ranges found: food (0.57-41.9 µg kg–1), (0.54-68 adult (0.43-638...
Carrots, chayote, and rice are foods widely consumed by the Brazilian population, so developing analytical methods that allow elemental characterization becomes extremely important. In this work, sample decomposition method is proposed to prepare samples (raw cooked) of rice, carrots, chayote using dilute nitric acid. The underwent microwave-assisted acid (HNO3/H2O2) for subsequent determination ICP OES metals Al, Cd, Cr, Cu, Fe, Pb flame spectrophotometer K Na. Two were used. Method 1: 260...
Abstract This study investigated the levels of total mercury (THg) in Spanish samples baby food, fast and daily meal, which people different ages consume, to evaluate potential toxicological risks through contribution Tolerable Daily Intake (TDI) this element. The concentrations were determined thirteen commercial foods for infants 6 12 months old, six kinds prepared children, nine canteen menus adults. Samples homogenized, freeze-dried, analyzed using a direct analyzer (DMA). concentration...
Abstract This study aimed to evaluate the metal exposure through concentration of essential and toxic micro-minerals in biological samples Phrynops geoffroanus from an anthropized river. The work was carried out four areas with different flow characteristics uses river, where individuals both sexes were captured during dry rainy seasons. elements Al, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Zn, quantified serum (168), muscle (62), liver (61), kidney (61) by Inductively Coupled Plasma Optical...
