| 内容記述 | To investigate the characteristics of mercury in the River Muka， we sampled river-water and bottom sediments， and analized them by flameless atomic absorption using a Hitachi Model 207 atomic absoption spectrometer. Average mercury content in the river-water ranged from 3×14^<?4> to 1.2×10^<?3>ppm，and the experimental values were very scattered，i.e.，relative standard deviations were 14?22％，but those samples filtered using a glass filter 3G4 and supernatant water that left standing for some weeks contained no detectable mercury(lower limit of detection of about 0.5 ppb). The bottom sediments(2 mm. Under) were separated into six parts according to grain size. Mercury concentrations were found in all samples， with the level being fairly dependent on the size factor of the sediment. The highest concentrations of mercury have been detected in the group of 1?5μ，however，when only boiling with 0.1 N H_2S0_4 under a condenser as pretreatment， mercury in sediments has not been detected. From the experiments described，we may conclude that mercury in river-water from the River Muka is present not in solution，but as a dispersion of fine grain ore cinnabar，and its grain size is about 5?10μ. | |||||
