Description of key information
Not required by REACH annexes. However, a mesocosm study (Heimbach, 1993) with pMDI exists in which the toxicity towards macrophytes (Potamogeton crispus and Zannichellia palustris) was assessed. No toxicity was observed at a loading of 1000 and 10,000 mg/L. The absence of any adverse finding in the 112-day mesocosm study on pMDI strongly supports that there is no long-term aquatic hazard to be expected from the substances of the MDI category.
Key value for chemical safety assessment
Additional information
In a mesocosm study (Heimbach, 1993), a pond was exposed to a loading of 1000 and 10,000 mg/L of pMDI during 112 days. Three 4.5 m3 ponds were filled with groundwater and added natural lake sediment (15 cm). The systems were left outdoors for six months. Links between ponds were then closed; fish were added to ponds (in cages) and substance added to two ponds at two different loadings (1000 and 10,000 mg/L). The third pond was the control. The substance was added directly onto the bottom of the ponds with a hose. The toxicity effects were assessed to two macrophytes, Potamogeton crispus and Zannichellia palustris. No effects were seen at both loadings. The MDI applied polymerized and formed a stable layer on the sediment surface of the ponds. At the end of the study, approximately 100% of the substance was found in the sediment as hardened material.
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.
