Sago Sago Sago is a starch extracted from the spongy centre, or pith, of various tropical palm stems, especially that of "Metroxylon sagu". It is a major staple food for the lowland peoples of New Guinea and the Moluccas, where it is called "saksak", "rabia" and "sagu". The largest supply of sago comes from Southeast Asia, particularly Indonesia and Malaysia. Large quantities of sago are sent to Europe and North America for cooking purposes. It is traditionally cooked and eaten in various forms, such as rolled into balls, mixed with boiling water to form a glue-like paste (papeda), or as a
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
