Description of key information

Additional information

The test item has a solubility of about 8.8 g/L. It has a low volatility (3.3E-7 hPa at 25°C) and should therefore not be released into air. According to its low log Kow of -1.1, a low affinity for soil / sediment and consequently a compartmentalization into water compartments would be expected after release to the environment.

Due to its toxicity for aquatic organisms, all of its uses take place in closed systems and effluents containing the substance are not released into wastewater without specific after treatment.

The test item displays slow biodegradability (ca 26% biodegradability) according to its BOD/COD ratio, < 10% DOC removal in a test for inherent biodegradability. According to known substance data, the substance is stable at high temperatures and acidic and neutral pH. Consequently, the substance is considered to be persistent in the environment.

Studies on direct phototransformation in water are not available but it is assumed on the basis of chemical structure and nature of use that the substance is not degraded by direct photolysis.

The test item has a log Kow of < -1.1. This value indicates that possible bioaccumulation in the food chain is not anticipated.

Adsorption to soil is deemed to be low, based on the very low partition coefficient value and high water solubility.
