Results and discussion
Any other information on results incl. tables
Avg.LC50(Moina micrura; 72-h) = 1,625 ppm superphosphate
Avg. LC50(Cyclops viridis; 72-h) = 2,305 ppm superphosphate
Avg. LC50(Branchiura sowerbyi; 96-h) = 3,320 ppm superphosphate
Avg. LC50(Chironomus; 96-h) = 1,510 ppm superphosphate
Avg. LC50(Dragonfly nymph; 96-h) = 1,133 ppm superphosphate
Avg. LC50(Planorbis exustus; 96-h) = 5,005 ppm superphosphate
Avg. LC50(Lymnaea leuteola; 96-h) = 2,950 ppm superphosphate
Avg. LC50(Viviparus bengalensis; 96-h) = 2,350 ppm superphosphate
Applicant's summary and conclusion
- Executive summary:
A study for acute aquatic toxicity was performed with various invertebrate species. This study indicates that superphosphate is practically nontoxic to aquatic invertebrates. No significant difference in toxicity was observed at the two temperatures tested. Results are reported as the average of the two values for each species. All LC50 (72 resp. 96h) values found were above 1000 ppm.
