Abstract

The presence of heavy metals in rice plants can be a problem if the content exceeds the specified threshold. The aim of the study was to determine the content of heavy metals in purple rice stems and purple rice broken rice in Kelonpok Tani Indah Sakato I Kanagarian Kasang, Batang Anai District, Padang Pariaman Regency. Purple rice stem and ‘milled purple rice’ were analysed using AAS (Atomic Absorption Spectrophotometer). . Analysis of heavy metals includes lead (Pb), manganese (Mn), copper (Cu), zinc (Zn) and cadmium (Cd). The results of laboratory analysis showed that lead (Pb) in purple rice straw and milled purple rice was detected at 0.0256 mg / kg and 0.0196 mg / kg. Manganese (Mn) metal was detected at 0.1046 mg / kg and 0.3675 mg / kg, the copper (Cu) metal detected was 0.01165 mg / kg and 0.010815 mg / kg. Furthermore, Cadmium (Cd) metal was detected at 0.01465 mg / kg and 0.0141 mg / kg and zinc (Zn) metal detected at 0.083125 mg / kg and 0.2659 mg / kg. All observations of metal content do not exceed the quality standards set by ANZECC. It can be concluded that Purple rice stem and ‘milled rice’ are safe for consumption.
