| Popis: | Bacteria were found to be the principal cause of instability of mercury in laboratory solutions. The volatilization loss rate increased rapidly after a variable lag period and then leveled off with increasing time. The marked reduction in the loss rate of mercury is a result of its combination with bacterial cells and metabolites. Reagents which either oxidize or solubilize organics removed mercury most effectively from sample containers in which mercury-bearing water had been stored. A small amount of mercury was found to have diffused into the polyethylene bottles. Solute mercury was most effectively stabilized in laboratory solutions and water samples with 0.05 percent KMnO/sub 4/ without acidification. (auth) |
