Description of key information

One inherent biodegradability study is available for the diazopyrazolone pigments pointing out low biodegradability. Due to this a more stringent study on ready biodegradability is scientificaly not necessary. The three substances of the Diazopyrazolone group are to be regarded as not readily and not inherently biodegradable.

The registration substance is highly insoluble in water and indirect or direct exposure of soil and sediment is not expected. The CSA does not indicate the need for further investigations.

The P-criterion of the PBT assessment is accepted. Therefore no further testing is warranted as no further relevant information could be expected from additional testing.
