Description of key information

The test reveals a low hazard potential to terrestrial organisms.

Key value for chemical safety assessment

Additional information

Only one valid study was performed by Yoon et al. (1985). The test was conducted comparable to OECD TG 477. As this test is usually used for testing on genotoxic effects on fruit flies (Drosophila spec.) lethal effects of substances may be tested in parallel. The test organisms were fed with with a stock solution of known concentration. After 3 days of exposure, a mortality of 48% (= LC48) was reported for a concentration of ca. 33300 mg/l.

However, this test can not be used for the derivation of the PNECsoil, since Drosophila adult male animals were treated with the test substance at rather high concentrations. Interaction with soil was not guaranteed and therefore, it may not be concluded, that the exposure path was the one required for the derivation of the PNECsoil.
