Biodegradation in water: screening test

In a key study the ready biodegradability of the test substance was determined according to the EEC-Directive 92/69 (1992); equivalent to OECD Guideline 301 A (1993) and ISO Standard 7827 (1994). The biodegradation degree (DOC removal) after 28 days was determined to be 80 – 90 %. The test substance was considered to be readily biodegradable according to OECD criteria.

 

Biodegradation in water and sediment: simulation tests

In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex IX, Section 9.2.1.4., no study on biodegradation in water and sediment: simulation tests, needs to be conducted, if the substance is readily biodegradable, or if direct and indirect exposure of sediment is unlikely. Since the ready biodegradability of the test substance was proven (please refer to IUCLID section 5.2.1), an experimental investigation on biodegradation of the test substance in water and sediment was not considered necessary.

 

Biodegradation in soil

In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex IX, Section 9.2.1.3., no study on biodegradation in soil needs to be conducted, if the substance is readily biodegradable, or if direct and indirect exposure of soil is unlikely. Since the ready biodegradability of the test substance was proven (please refer to IUCLID section 5.2.1), an experimental investigation on biodegradation of the test substance in soil was not considered necessary.
