Title 28-Day Inhalation Study with 2,4-D (preliminary results; test in progress)

Date 31-OCT-07

3. Type of incident identified in the study

Increased health or environmental risk

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)

Study initiated in response to US EPA 2,4-D RED Data Call-In. Exposures + doses in study were: Nose-only (6 hrs/day, 5 days/week for 4 weeks); Five doses: 0.0, 0.05, 0.1, 0.3, 1.0 mg/L. Preliminary findings are that female body weights were reduced in the 1.0 mg/L dose group starting by day 14 and remained lower in the recovery group during the four week period following removal from the exposure. At the 0.3 and 1.0 mg/L dose levels, there were some effects noted in the clinical chemistry and hematology evaluations. There were indications of organ weight effects at the 1.0 mg/L dose level recovery group. Histopathological examination is incomplete at this time, and the study evaluation remains in progress.

5. a) Was the study discontinued before completion?

No

5. b) Provide the reason for discontinuation
