- Other biological observations: Earthworms at 1000 and 500 mg/kg were observed on the soil surface from test commencement through day 10. - Reported statistics and error estimates:
- The median lethal concentration (LC50) at 7 and 14 days was determined by probit analysis (Finney D.J., 1971, Probit analysis, 3rd edition, Cambridge University Press). Differences in body weight were analyzed by analysis of variance (ANOVA). Pairwise comparisons between each of the doses and the control were performed using Dunnett’s test at the 5 % significance level. The probit transformed concentrations of TS were subject to a regression procedure against logarithmically transformed concentrations of TS with a Newton-Raphson maximum likelihood iterative procedure being used to obtain parameter estimates. From the model the LC50 value was estimated. The goodness of fit was checked via the Pearson chi-squared test statistic. A significant chi-squared test statistic indicated heterogeneity of variances between the observed and expected % mortality values. If the test statistic was significant at the 1 % level, the variances and covariances were adjusted by a heterogeneity factor. Following this, the confidence limits were not reported and the LC50 values should be treated with caution.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- Mortality of control animals < 10 %
- Conclusions:
- 14d LC50 (survival, TWA) = 6.96 mg a.i. /kg dry soil ; 14d LC50 (survival, nominal) = 86.6 mg a.i. /kg dry soil
14d NOEC (survival, TWA) = 0.71 mg a.i. /kg dry soil; 14d NOEC (survival, nominal) = 8.83 mg a.i. /kg dry soil - Executive summary:
OECD Method 207, Acute toxicity to the earthworm. Kathon™886F had no significant effect on earthworm weight under the conditions of this test. KathonTM 886F is not highly toxic to earthworms over a 14-day test period. 14 dLC50= 613 mg/kg whole product (soil); 86.6 mg a.i./kg (soil); 14 d NOEC = 62.5 mg whole product/kg (survival); 8.8 mg a.i./kg.
