Description of key information
Short-term toxicity to fish
DMDC (CAS 6864 -37 -5) is with high probability acutely not harmful to fish (96 -h LC50 > 100 mg/L, NITE 2002).
Long-term toxicity to fish
The intrinsic properties of the Substance indicate that significant and relevant long-term effects on fish will not occur (NOEC > 1 mg/L).
Short-term toxicity to aquatic invertebrates
DMDC (CAS 6864 -37 -5) is acutely toxic to aquatic invertebrates (48 -h EC50 = 4.57 mg/L, NITE, 2002).
Long-term toxicity to aquatic invertebrates
Chronic effects on aquatic invertebrates are not expected (21 -d NOEC = 4.0 mg/L, NITE, 2003).
Toxicity to aquatic algae
DMDC (CAS 6864 -37 -5) is acutely toxic to aquatic algae (72 -h ErC50 = 7.9 mg/L, 72 -h ErC10 = 4.1 mg/L, NITE, 2002).
Toxicity to microorganisms
The inhibition of the degradation activity of activated sludge in a STP is not anticipated when introduced in appropriate low concentrations (30 -min EC20 = 160 mg/L, BASF AG, 1990).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
