STUDY TITLE: Hexabromocyclododecane (HBCD): A Toxicity Test to Determine theEffects of the Test Substance on Seedling Emergence of Six Species ofPlants
GUIDELINES: OECD Guideline for Testing of Chemicals, Proposal for Revision of Guideline 208: Terrestrial Non-Target Plant Tests
OPPTS 850.4100 (Public Draft)
OPPTS 850.4225 (Public Draft)
NOMINAL TEST LEVELS: 0 (Negative Control), 40, 105, 276, 725, 1904, 5000 mg HBCD/kg dry soil
MEAN MEASURED TEST LEVELS: 0 (Negative Control), 31.3, 97.8, 297, 764, 2230, and 6200 mg HBCD/kg dry soil
STUDY INITIATION: April 18, 2002
Experimental Start (OECD): May 8, 2002
Experimental Start (EPA): May 8, 2002
Experimental Termination: June 3, 2002
STUDY COMPLETION: August 21, 2002
LENGTH OF TEST: 21 days
TEST SPECIES: Corn (Zea mays),Cucumber (Cucumis sativa),Onion (Allium cepa),Ryegrass (Lolium perenne),Soybean (Glycine max),Tomato (Lycopersicon esculentum)
RESULTS: The soil incorporation of Hexabromocyclodododecane (HBCD) caused no effects onemergence, survival, or growth for any of the six plant species tested. Therefore, the highest nominal soil concentration tested, 5000 mg HBCD/kg dry soil, was considered to be the NOEC for these test species.
