Abstract :
This research was conducted in 2016 with the aim of investigating the concentration of heavy metals of cadmium, lead and arsenic in ten rice imported in Dezful. This experiment was carried out 3 replications and in the form of the completely randomized design(CRD). Statistical analyses were performed using the MSTST-C statistical package and means were compared with Duncan test at 5 percent level. In this study, the means of concentrations of Cadmium, Lead and Arsenic in the all rice samples were 1.063±0.012, 31.1± 1.04 and 124.5± 3.43 µg. Kg-1, respectively. The results of the analysis of variance showed that there was a significant difference in among the studied rices relate to the amount of cadmium, Lead and Arsenic at the level of one percent. The results showed that the maximum concentrations of cadmium, Lead and Arsenic were in 5, 2 and 2 rices (1.36, 58.5 and 146 µg. Kg-1, respectively) and also minimum concentrations of cadmium, Lead and Arsenic were in (9, 10), 8 and 10 (0.93, 15.8 and 0.95 µg. Kg-1, respectively). amount of cadmium and Lead in the all rice samples were lower than the limit standard of that were provided by the food and drug Administration and the amount of Arsenic in 1, 2, 3, 4, 5 and 6 were more than the limit standard that was provided by the food and drug Administration.
