Abstract:

Sea water intrusion and watershed pollution from mining and plantations in Kalimantan’s tidal paddy fields will impact heavy metal levels in local Banjar rice. To determine exposure to heavy metals in various Banjar local rice. The content of heavy metals in 9 types of Banjar local rice was examined using the Atomic absorption spectroscopy (AAS) test method at the Center for Industry Research and Standardization.  Contamination content of heavy metal cadmium, mercurtiy, lead, zinc, selenium in Banjar local rice does not exceed the maximum standard limit for contamination in foodstuffs according to SNI. However, the iron content in Siam Gambut rice exceeds the upper limit of the value that can still be tolerated by the body. Local Banjar rice does not contain any heavy metals that could be detrimental to the health if eaten.
