Languages of publication
Short white rice grains produced locally from Mahaica, Guyana were collected from the rice farm and analyzed for ten trace elements by flame atomic absorption spectrometer. The concentrations of the trace elements investigated are as follows: - Ca (76.81), Mg (54.30), Fe (28.2), Cu (4.90), Zn (71.16) and Mn (14.33) mg/Kg. There had been controversial reports about the toxic elements normally present in the rice produced in different areas and conditions. The other four toxic elements As, Co, Pb and Al were also analyzed but not detected. With reference to the literature on the maximum daily intakes for human consumption, the concentration levels were all below the literature except for zinc and manganese
