The minor and trace element content of diet samples from two different social population groups were determined. Samples were prepared by duplicate portion technique by colecting everything 16 subjects ate and drank during a 3-day period. Samples were homogenized, freeze-dried and elemental concentrations of Br, Co, Cr, Cs, Fe, K, Na, Rb, Sc, Se and Zn were determined by instrumental neutron activation analysis. Elemental concentrations and daily dietary intake of the elements were compared with the diets of other nations.

DAILY DIETARY-INTAKE OF MINOR AND TRACE-ELEMENTS BY UPPER SOCIAL-GROUPS IN TAIWAN
LIU, SM; CHUNG, C; CHUANG, JT; WANG, CF; ARAS, NK (Springer Science and Business Media LLC, 1991-08-01)
Sixteen minor and trace element contents of diet samples from three different social population groups in Taiwan were determined. Samples were prepared using duplicate portion technique by collecting the 15 subjects ate and drank during a 3-day period. Samples were homogenized, freeze-dried, and elemental concentration of minor and trace elements were determined by instrumental neutron activation analysis. Elemental concentrations and daily dietary intake of the elements were compared with those in the othe...
Occurrence of fungi and their mycotoxins in individual Turkish dried figs
Senyuva, H. Z.; Gilbert, J.; Samson, R. A.; Özcan Kabasakal, Süreyya; Ozturkoglu, S.; Onal, D. (Wageningen Academic Publishers, 2008-02-01)
Fifty individual figs which had been rejected as potentially contaminated by sorting under UV light were separately analysed to identify the presence of fungi and their mycotoxins. Aflatoxin B-1 was found in 49 samples with levels ranging from 0.7 to 222 ng g(-1), with 40 individual figs containing more than 2 ng g(-1), indicating the efficacy of the UV screening process in identifying contaminated fruit. Ochratoxin A (OTA) was found in 32 of the figs at levels from 0.4 to 1710 ng g(-1), with 50% of the sam...
Dating of Black Sea sediments from Romanian coast using natural Pb-210 and fallout Cs-137
Aycik, GA; Cetaku, D; Erten, HN; Salihoglu, I (Springer Science and Business Media LLC, 2004-01-01)
The sediment samples collected near the shore from Romania were used for the determination of levels of natural Pb-210, Ra-226 and fallout Cs-137 radionuclides. The sediment samples were dried and ground to a fine powder. Airtight sealed samples were counted by gamma-spectrometer with 110 cm(3) well-type HPGe detector for one week each. By using the isotopic analysis results, sediment accumulation rate was determined. A sedimentation rate of 0.20 +/- 0.01 cm.y(-1) was determined using Pb-210 method and 0.15...
SODIUM, RUBIDIUM AND CESIUM UPTAKE ON LOS-TRANCOS CLAY
GOKTURK, H; DYER, A (Springer Science and Business Media LLC, 1994-10-03)
The uptake of sodium, caesium and rubidium onto Los Trances clay was studied using the batch method. Sodium-22, rubidium-86 and caesium-137 were used as tracers. In most of the experiments cation concentrations used were 0.01 N. Triple distilled and deionized water ware used and the grain size of all solid particles was less than or equal to 53 mu m. In all cases a few hours of shaking was enough to reach the equilibrium. The ion exchange isotherm experiments were performed by using ammonium forms of the cl...
DETERMINATION OF SELENIUM IN HUMAN DIETS BY RADIOCHEMICAL NEUTRON-ACTIVATION ANALYSIS
ELHALLAQ, YH; GOKMEN, IG; ARAS, NK; Gökmen, Ali (Royal Society of Chemistry (RSC), 1992-03-01)
A post-irradiation radiochemical separation technique was tested for the determination of selenium levels in diet samples, collected by using a duplicate portion technique, from both rural and urban population groups in Turkey. The technique involved sample irradiation, acid digestion, selective distillation, precipitation and filtration steps. During the separations it was possible to determine the yield of each sample using a stable selenium carrier. An average chemical yield of 71 +/- 3% was obtained ...
