Abstract: A significant issue in food safety is the depletion of vital components in rice, Bangladesh’s main agricultural product, due to various genetic and biological factors. A randomized sampling approach was employed to gather five popular rice varieties—Paijam, Swarna Bullet, BRRI Dhan-28, BRRI Dhan-29, and Chinigura—from different retail outlets in five upazilas within the Barishal district. This research focused on analyzing their proximate composition, heavy metal content, and related health risks. The proximate composition and heavy metal concentrations were assessed using AOAC methods and ICP-MS, respectively. The findings revealed notable differences (P
