Dietary intake of minerals and trace elements in rice on the Jamaican market

“…Cobalt is an essential trace element as a constituent of vitamin B 12 and some metalloproteins, though its toxicity in many biological systems depends on its concentration range (Antoine et al, 2012). Dietary deficiencies may lead to pernicious anaemia which As an essential element, Ni has several possible roles in the maintenance and production of cells, and as an activator of certain enzyme systems (Bakircioglu et al, 2011).…”

Trace elements were determined in five types of cheese, cream and butter using inductively coupled plasma-optical emission spectrometry. In cheese samples trace elements were measured as follows (mg/kg): Al 0.01-3.93, Co<0.005, Cr 0.005-1.66, Li 0.008-0.056, Mn 0.068-5.37, Mo 0.003-0.225, Ni 0.01-0.163 and Sr 0.085-3.49. There were significant differences considering the concentrations of Mn, Cr and Al (p<0.01, all) among the analysed dairy products. There were no significant differences in Sr, Mo, Ni and Li levels among products. The highest levels were found in following products (mg/kg): 4.23 Mn in semi-hard fat cheese, 2.43 Sr in cream cheese, 0.18 Mo in cream, 0.14 Ni and 0.028 Li in melted cheese, 1.13 Cr and 3.87 Al in butter. The trace element concentrations measured in cheeses and butter varied compared to the literature data. Concentrations of Al, Cr, Mn and Mo found in cheeses and Mn and Ni in butter were in line with contents reported in other countries. These results may demonstrate differences in production processes between countries. The estimated daily intakes (EDIs) calculated for Cr, Mn, Mo and Ni in cheeses showed a low contribution (0.59-3.38 %) to the reference values for the permitted daily exposure (PDE) for these elements. However, the high contribution of Al concentrations (56 and 124 %) to PTWI (provisional maximum tolerable daily intake) calculated in fresh and melted cheese may pose a health risk to consumers.

Abstract. For long-term radiation dose assessment models, food ingestion is one of the major exposure pathways to human. In general, the stable isotopes can serve as analogues of radioisotopes. In this study, rice samples were collected from 30 paddy fields in Si Sa Ket, Yasothon and Roi Et in the northeast of Thailand in November 2014. The concentrations of stable cesium (Cs-133) and strontium (Sr-88) in polished rice were determined by inductively coupled plasma mass spectrometry (ICP-MS). The standard reference material of rice flour (NIST 1568a) with spiked Cs and Sr was used to validate the analytical method. The concentration of Cs in polished rice from Si Sa Ket, Yasothon and Roi Et was 0.158  0.167 mg kg -1 , 0.090  0.117 mg kg -1 and 0.054  0.031 mg kg -1 , respectively. The concentration of Sr in polished rice from Si Sa Ket, Yasothon and Roi Et was 0.351  0.108 mg kg -1 , 0.364  0.215 mg kg -1 and 0.287  0.102 mg kg -1 , respectively. Comparison of the results with Japanese data before the Fukushima Di-ichi nuclear power plant accident showed that the concentrations of both Cs and Sr for Thai rice were higher than those for Japanese rice.
