Sago Lane the dead", but it's actually on Sago Lane. Sago Street was where brothels were located. Sago Lane is known as "ho ba ni au koi" in Hokkien, which literally means "the street behind Ho Man Nin". Ho Man Nin is the "chop" of a well known singing hall in neighbouring Sago Street. 19th century: The lane received its name because during the 1840s, there were numerous sago factories in both Sago Street and Lane. The sago was then taken from the powdery pith of the trunk of the rumbia palm and processed into flour that was used to make desserts,
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
