Project:
Biology -- Water quality analysis in a martian environment: LC50
Daphnia magna exposed to GreenHab effluent


Personnel:
Cheryl Wartman


Operations Data Collected:
Samples taken for 1, 12 and 24 hour from the effluent exposure of water
from tank after the UV filter.

1 hour data (# dead):
0.0 % A = 0 B = 0
6.25% A = 0 B = 0
12.5 % A = 0 B = 0
25.0 % A = 0 B = 0
50.0 % A = 0 B = 0
100.0 % A = 0 B = 0

12 hour data (# dead):
0.0 % A = 1 B = 0
6.25% A = 1 B = 1
12.5 % A = 1 B = 0
25.0 % A = 0 B = 1
50.0 % A = 0 B = 3
100.0 % A = 2 B = 2

24 hour data will be taken at 10:18 pm tonight. Cumulative data and
results will be calculated after I return home.

The established colony of daphnia was terminated. Inventory for the
Biology section of the lab was completed.


Technical/Equipment Issues:
none


Discussion:
Above data will be analyzed to determine LC50.


Questions for CSO:
None at this time.
