Table 1. Mobility results
A study was conducted to determine the
short-term toxicity of the test substance, C18 TMAC (91.6% active) to
aquatic invertebrates according to OECD Guideline 202. Twenty Daphnia
magna per group were exposed under static conditions to nominal
concentrations of 0.01, 0.018, 0.032, 0.058 and 0.105 mg/L. Immobility
was recoded at regular intervals. No analytical dose
verification was conducted. At 0.01 mg/L, one animal was immobile after
48 h. This was in the range allowed by the quality criteria for the
control group. At the next higher concentration of 0.018 mg/L, all
animals survived. The 48 h NOEC was therefore established at 0.018 mg/L.
The lowest concentration producing 100% immobilization was 0.058 mg/L.
The 48 h EC50 was calculated to be 0.04 mg/L (equivalent to 0.037 mg
a.i./L), with 95% confidence limits of 0.03 and 0.04 mg/L. Under the
study conditions, the 48h EC50 and NOEC of the test substance were
calculated to be 0.04 mg/L (equivalent to 0.037 mg a.i./L) and 0.018
mg/L (equivalent to 0.016 mg a.i./L), respectively (Mark, 1993).
The 48 h EC50 value of the test substance
for toxicity aquatic invertebrates, which was determined at 0.037 mg
a.i./L (nominal) has been considered further for hazard/risk assessment.
