In these days we need to know about food health and establish a safe system of production. But unfortunately, wrong agricultural practices yield undesirable results. Therefore, this study aimed to investigate the amount of rice contamination in the main samples and ratoon. Materials and Methods: This paper concerns the biological effects of pollution on whole rice seeds and investigates two types of rice, namely ratoon and main grain with Atomic Absorption Spectroscopy technique. Also we analyzed the measured parameters using ANOVA for mean comparison in SPSS using DUNCAN tests. Results: Accumulation of heavy metals (Cd, Cr, Ni, Hg, Pb, and As) in the rice grain is reported at different levels. The investigation confirmed that the level of heavy metals in ratoon grain is higher than in main grains. For example, the accumulation of Ni, Pb, and Cd respectively were equal to 0.7, 0.18, and 0.072 mg/kg in ratoon grains, and they were higher than FAO/WHO and ISIRI limits for the allowed heavy metals values in rice. Conclusion: According to the findings, unlike the conception of the public, ratoon grain is polluted more than the main grain. Therefore, since rice is the staple food of a large human population, it is extremely important to prevent heavy metal absorption, making it safe for consumption.
