Semivariogram, one of the geostatistical methods, is considered a useful method to explore the spatial variation of Cd, Cu, Ni, Pb and Zn. The main objectives of this study were (1) to investigate the concentrations of potentially hazardous metals in soil and rice grain, (2) to determine the spatial correlations and distribution of potentially hazardous metals in soil and rice grain, and (3) to identify the main soil properties influencing potentially hazardous metal concentrations in rice grain.
