| AN INQUIRY INTO THE MERCURY ABSORPTION OF SPARTINA ANGLICA AND ITS ENVIRONMENTAL PURIFICATION EFFECT |
|
|
| Abstract: |
| This is a report of preliminary water culture experiments of absorption of mercury by big rice grass, Spartina anglica, which is a very vigorous and stress resistant halophyte. The amounts of mercury absorbed by the shoots from water culture of different concentrations are 10-56 times the initial amounts and those absorbed by roots are 250-2500 times. The most efficient absorption by the tillers was found to be almost half of the original amount in the 1 ppm culture after four-week absorption. The curve of S. anglica absorption of mercury is a positive relative exponent curve. Hence S. anglica is found to be rather effective as an agent to remove pollutants, especially in the case of mercury. |
