The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

Assessment of this endpoint and derivation of adsorption coefficients are element-based (i.e., not substance-based). A total of five studies was used in a weight of evidence approach to cover the endpoint. Reliable data were available for soil, suspended matter, and sediment. The following final key values were retained: a log Kp of 5.00 for suspended matter-water, a log Kp of 5.47 for sediment-water, and a log Kp of 4.13 for soil-water. Adsorption of zirconium to sediment and suspended matter appears to be slightly more pronounced than for soil.
