Description of key information
For the Daphnia Magna reproduction study:
Mortality (immobilization) occurred predominantly at the highest test loading rates of 1.8, 3.2 and 5.6 mg/L resulting in 100% mortality by Days 13, 2 and 2 respectively. Significant mortality (immobilization) also occurred throughout the test in the 1.0 mg/L loading rate WAF group resulting in 50% mortality by Day 15.The LOEL was therefore considered to be 1.0 mg/L.
The NOEL was 0.56 mg/L as, although there mortalities were (immobilization) observed in the parental generation (P1) at the test loading rate of 0.56 mg/K on Day 4, there were no significant differences (Pā„0.05) when compared to the control group, consequently, this mortality was classed as an inadvertent mortality for the purposes of the statistical analysis.
From the Algal growth study:
The average specific growth rate EL50 = >100 mg/L and the NOEL = 10 mg/L
The Acute Toxicity to fish study:
the 96h LLR50 was 5.9 mg/L.
