Sago first wash. Because many traditional people rely on sago-palm as their main food staple and because those supplies of these are not unlimited, in some areas commercial or industrial harvesting of wild stands of sago-palm can conflict with the food needs of local communities. 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
Simultaneously extracted metals and Acid-volatile sulfide initially unbound to AVS (due to insufficient AVS in the sediment to "mop up" all the metal ions). The concentrations of metals in the acid solution can be measured by a number of analytical chemistry methods, including atomic emission spectrometry, atomic absorption spectrometry (AAS), or mass spectrometry. These are known as "simultaneously extracted metals" because they are the metals liberated from the sediment "while the volatilization of sulfide is occurring". Metals extracted from sediment by digestion, or with a different acid than HCl are "not" simultaneously extracted metals. By correcting appropriately for dilution, the SEM concentration in the sediment can
