Urea

Summary

Persistence. It cannot be excluded that urea is persistent, due to the lack of data.
Bioaccumulation. Urea does not have the potential to bioaccumulate in aquatic organisms.
Toxicity. Urea has low acute toxicity.
Risk. Available ecotoxicological data do not exclude the risk of environmental impact.

The data on hazard and risk are based on previous environmental information on fass.se 2011-05-11. Environmental information is missing (2022-06-21). It is voluntary for manufacturers to provide information about environmental impact on fass.se.

Detailed information

Fass environmental information

Fass environmental information for Caress (urea) from MSD (downloaded 2011-05-11).

Hazard

Persistence: Carbamide is readily degraded in the environment (EPISuite).

Bioaccumulation: Log Kow = -2,11 (Hansch, C et al., 1995). BCF calculation (EPISuite) = 3,16.

Acute toxicity: There are data for 1 trophic level, Daphnia (unknown species) = EC50 3910000 microg/L (48-hr unknown method).

Risk

Available ecotoxicological data do not exclude the risk of environmental impact.
