Description of key information

The following study was provided as the key study to fulfil the data requirement:
Clarke. N 2010 ASSESSMENT OF THE INHIBITORY EFFECT ON THE RESPIRATION OF ACTIVATED SEWAGE SLUDGE Testing laboratory: Harlan Laboratories Ltd, Shardlow Business Park, Shardlow, Derbyshire, DE72 2GD, UK Owner company: Chemtura Corporation, 199 Benson Road, Middlebury, CONNECTICUT 06749, UNITED STATES OF AMERICA Report no.: 3103/0069 Report date: 2010-08-16
The effect of the test item on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 of greater than 1000 mg/l. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 1000 mg/l.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

A reliability rating of 1 was assigned to the key study, Clarke N (2010). The study was conducted in accordance with a recognised guideline and GLP and was therefore considered of high reliability and adequate to fulfil the data requirement.

Key value for chemical safety assessment:

EC50 >1000 mg/L
