摘要：

Neutron activation analysis (NAA) was used for determining chemical elements in rice grains of four different cultivars (IRGA424, IRGA424 RI, Guri Inta, Puita Inta) produced in four geographic regions of Rio Grande do Sul state, Brazil. Considering toxic elements, As varied from 0.027 to 0.646 mg/kg, while Cd was always lower than the detection limit of 0.25 mg/kg. Applying principal component and cluster analysis, As, Br, Co, Cs, Na, Rb and Zn presented potential to be used to distinguish rice grains from different regions, while no discrimination was obtained amongst cultivars.
