Description of key information

Bioaccumulation of urea is not predicted.

Key value for chemical safety assessment

Additional information

A study is not required: due to the low log Kow value urea is not likely to undergo bioaccumulation. Additionally, urea is utilised by fish species as a nutrient and is excreted by some species as a product of protein catabolism.
