Description of key information

A chronic earthworm study and an nitrogen transformation test was performed according to OECD 222 and OECD 216 respectively for the structurally similar substance DMDC (CAS 6864-37-5):
- Chronic earthworm test (OECD 222): 56-d EC10 for effects on reproduction: 228 mg/kg soil dw (95% CL: 115.6 / 450.8) (BASF, 2013; report No. 68E0695/00G009).
- Nitrogen tranformation test (OECD 216): 28-d EC10 > 1000 mg/kg soil dw (BASF SE, 2013; project no. 37G0695/00X032)

Key value for chemical safety assessment

Additional information

Invertebrates are the most sensitive group as indicated from aquatic toxicity data. A chronic earthworm study (limit test) is planned for the structurally similar substance DMDC (CAS 6864-37-5) to cover this endpoint in accordance with REACh guidance for compounds in soil hazard category 3 (Table R.7.11-2). Based on the outcome of this test and the screening level risk assessment, a decision will be rendered as to whether additional terrestrial toxicity testing is necessary for the test substance.
