Description of key information

In accordance with Column 2 of REACH Annex IX and X Sections 9.2.1.4 and 9.1.5, respectively, the study does not need to be conducted as the substance is readily biodegradable, direct and inderect exposure to the sediment is unlikely and all identified uses of the substance are assessed as safe for the environment.  

Key value for chemical safety assessment

Additional information

This data point has been waived for terephthalic acid on the grounds that exposure is not expected to occur and that TPA is readily biodegradable and has no strong tendency to partition toward organic matter in sediment. Under these circumstances, data for the effects of terephthalic acid on sediment-dwelling organisms are considered unnecessary.
