Additional information

A read across approach was applied with the supporting substance 2-chlor-4, 6-dihydroxy-1,3,5-triazin, mononatriumsalz. In a key study according to OECD guideline 301 E and EU-method C.4-B (90-0014-DGO) the biodegradation behaviour of the test item was assessed. The test revealed that after an exposure period of 28 days no biodegradation occurred. Therefore, the test item was considered to be not ready biodegradable. Additionally the biological oxygen demand of the test item was investigated in a supporting study (90-0013-DGO). After an exposure period of 5 days the test revealed that the BOD was 5% at a concentration of 2 mg/L test item and 0 % at a concentration of 10 mg/L.
