Sago monitor Sago monitor The sago monitor or torch monitor, Varanus obor, is a species of monitor lizards endemic to the Indonesian island of Sanana. "Varanus obor" is the only melanistic member of the Pacific monitor ("V. indicus") group, and the only species belonging to the subgenus "Euprepiosaurus", which has prominent red-orange markings on its body. Proportions of the body and the construction of scales most closely resemble "V. melinus", which can be found on the islands of Mangole and Taliabu. Most often, "V. obor" occurs in coastal sago palm swamps - a habitat that is underused by other species of the
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
