Subform VII: Scientific Study

1. Study Reference

Title Acute Dietary Toxicity of 2,4-D 2-EHE in Mice

Date 23-NOV-10

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)

The purpose of the study was to determine the dietary toxicity of 2,4-dichlorophenoxyacetic acid (2,4-D), administered as the 2-ethylhexyl ester (2-EHE) to small mammalian species. Specifically this Endocrine Disruption Screening Program (EDSP) assay/study is new information from a dietary lethal dose acute toxicity study (LDD50) with 2,4-D 2-EHE in mice. Because of extreme avoidance of the test diet, consumption values were reduced by over 90% compared to control animals. Based on food consumption and bodyweights, the LDD50 for 2,4-D 2-EHE is greater than 493 mg/kg. The Task Force is of the opinion that this study does not demonstrate that 2,4-D 2-EHE causes unreasonable adverse effects. Any adverse effects in this study were due to a lack of palatability and not toxicity of the dietary test material.
