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 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
