Description of key information

Results from a study with a population of microorganisms from a sewage treatment plant show that DINP does not inhibit respiration at a high concentration, in excess of its water solubility.  Results from a toxicity study with Photobacterium phosphoreum, show that DINP does not cause toxicity to an aquatic bacterium at a high concentration, in excess of its water solubility.

Key value for chemical safety assessment

Additional information

The results of toxicity studies with microorganisms single and as communities of sewage treatment plants show that DINP does not cause any toxicity within its water solubility limits.
