Subform VII: Scientific Study
1. Study Reference
Title Effects of 2,4-Dichlorophenol on Reproduction of the Predatory Mite Hypoaspis Aculeifer in Artificial Soil with 5% Peat
Date 24-NOV-11
2. a) Is an extension needed to translate the document?
No
3. Type of incident identified in the study
Presence of a component or derivitive
4. Describe the incident identified in the study (e.g. study demonstrates an increased risk to non-Hodgkin's Lymphoma after exposure to pesticide X)
2,4-dichlorophenol caused no significant effects on mortality of Hypoaspis aculeifer up to and including the concentration of 10 mg test item/kg soil. Reproduction was statistically significant at the concentrations of 1.25 mg test item/kg soil which was not considered to be treatment related. At 10 mg test item/kg soil reproduction was statistically significantly reduced. Therefore, the No Observed Effect Concentration (NOEC) was determined to be 5.0 mg test item/kg soil. The Lowest Observed Effect Concentration (LOEC) was determined to be 10 mg test item/kg soil and the EC50 was estimated to be greater than 10 mg test item/kg soil.
5. a) Was the study discontinued before completion?
No
