Abstract  

Rice plants were grown in an experimental field and separated at harvest into different components, including polished rice, rice bran, hull, straw and root. The distribution of chlorine in these components was determined by instrumental neutron activation analysis. The concentration of chlorine in the roots was the highest (4800 mg·kg−1 dry wt.) and that in the polished rice was the lowest (140 mg·kg−1 dry wt.) among the plant components. The content of chlorine in the polished rice was about 2% of the entire plant, and the rest was present in the inedible portions; about 75% of the total chlorine content was in the straw. The percentage of chlorine removed from the surface soil layer to the above ground biomass of the rice plants was calculated as 5% every year. The chlorine concentrations in leaf blades of different positions collected from four growing stages varied by more than one order of magnitude, and were well correlated with the sum concentrations of major cations (potassium + calcium + magnesium). This may be attributed to the fact that the translocation rate of chlorine among the leaf blades with age depends on the concentrations of the major cations.

Abstract  

Five varieties of rice have been analyzed to study the prevailing concentration and distribution of 10 trace elements in rice and rice husk. NAA in combination with AAS has been utilized for the determination of Hg, Pb, Cd, As, Br, Sb, Se, Ni, Al and Cs. The elemental ratios of rice to husk and within rice have been calculated to get information regarding their uptake channels. The daily supply of the elements to the human body has been estimated and from these the safety of the diet has been assessed by comparing with the suggested tolerance levels. A global distribution pattern of some of these elements in rice has also been evaluated.
