Aside from being the source for sago pith, the sago palm is a source of another delicacy for the indigenous peoples of Borneo:
Simultaneously extracted metals and Acid-volatile sulfide Life or Human Health Are Possible." The Ohio Environmental Protection Agency uses [SEM]/[AVS] in sediment quality guidelines for waters in that state. Simultaneously extracted metals and Acid-volatile sulfide Simultaneously extracted metals/Acid-volatile sulfide (SEM-AVS) is an approach used in the field of aquatic toxicology to assess the potential for metal ions found in sediment to cause toxic effects in organisms dwelling in the sediment. In this approach, the amounts of several heavy metals in a sediment sample are measured in a laboratory; at the same time, the amount of acid-volatile sulfide (sulfide which can be liberated from the sediment by treatment
