Algae growth inhibition 

Key value for chemical safety assessment

EC50 for freshwater algae:
0.016 mg/L
EC10 or NOEC for freshwater algae:
0.016 mg/L

Additional information

There was no significant difference between growth in test flasks at 100 p.p.m. nominal PB-370 and control flasks over the test period. The results indicate that the EC50 of PB-370 upon the growth of Selenastrum capricornutum, is greater than the maximum solubility of PB-370 in algal medium, under the conditions of the test. Thus, the water solubility value of 0.0156 mg/l was taken for chemical safety assessment.
