In the algae study, measured water
temperatures were within the 24 ± 2°C range established for the test.
Dissolved oxygen concentrations remained at or above 8.2 mg/L 91% of
saturation) throughout the test. The pH of test solutions tended to
increase relative to increases in algal densities, which is typical for
tests conducted with S. capricornutum. Test solutions ranged from 7.7 to
7.8 at initiation to 9.5 to 10.1 at exposure termination. The light
intensity was within the desired range of 4300 ± 10% lux. Changes in
cell densities were evaluated over 96-hours, and were used to calculate
areas under the growth curve (biomass) and growth rates for each 24-h
interval. After 72 and 96 h of exposure, no apparent treatment-related
effects on growth were observed at any of the loading rates tested. No
significant differences between the negative control and treated groups’
growth were detected (p>0.05). The 72 and 96-h EL50, EbL50 and ErL50
values based on cell density, area under the growth curve and growth
rate, respective, were >110 mg/L, the highest tested loading rate. The
72 and 96 h NOAELR for each parameter was 110 mg/L.
