Uptake and accumulation of As, Cd, Pb, Cr, Zn, Cu, Ni, Fe and Mn heavy metals in rice grains, their soil and tube well water were determined by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) in Kyonpyaw Township in March, 2015. Zn was detected in 8 of 14 rice samples and 7 were above maximum allowable concentration (MAC) (Zn=50 µg/g, GB 2762-2005) whereas Cu was accumulated in 8 and 5 showed above the MAC (Cu=10 µg/g, FAO/WHO, 1992). Ni was detected in 9 and 4 showed above the MAC (Ni=1.5 µg/g, FAO/WHO, 2001). Mn was present in 11 and 8 had above MAC (Mn=5 µg/g, USEPA 2007). Fe was detected in 10 and 5 had above MAC (Fe=5 µg/g, CODEX standards). In 8 Pb accumulated samples, 6 had above MAC (Pb=0.2 µg/g, GB 2762-2005). As was detected in 2, Cr in 5 and Cd in 6, but all were lower than their respective MAC. The order of metal concentrations in rice grain samples was Zn>Pb>Mn>Cu>Fe>Ni>Cd>Cr>As. In 14 soil samples, the concentrations of As, Cd, Pb, Cr, Zn, Cu, Fe and Mn were within MAC. However, the concentration of Ni in 8 samples were above MAC (Ni=40 µg/g). Fe and Mn were found in all 23 water samples whereas 19 Fe and 16 Mn samples had above MAC (Fe=0.3 ppm & Mn= 0.4 ppm, WHO, 2006). Among 23 As detected samples, 12 were higher than Myanmar Drinking Water Quality Standard (As=50 ppb). Cr in 18 and Pb in 6 were detected. However, concentration of one Cr and two Pb samples showed higher than MAC (Cr=0.05 ppm and Pb=0.01 ppm, WHO, 2006). The concentration of Zn, Cu and Ni were within MAC (Zn=3 ppm, Cu=2 ppm, Ni=0.07 ppm, WHO, 2006). Cd was detected in 14 but 4 were above MAC (Cd=3 ppb, WHO, 2006). The order of metal concentrations in water was Fe>Mn>As>Cd>Pb>Cr>Zn=Cu>Ni.
