Biodegradation in water: screening tests

The screening test inherent to the biodegradability of the substance was calculated using the software BIOWIN v4.10.

The results indicate that 1-chloro-3-nitrobenzene is not expected to be readily biodegradable.


Biodegradation in water: screening tests

Half life period of 1-chloro-3-nitrobenzene in water is observed to be 37.5 days (900 hrs.) while in sediment it is 337.5 days (8100 hrs). Based on these half life values of 1-chloro-3-nitrobenzene, it is concluded that the chemical is not persistent in water and sediment.


Biodegradation in soil

EPI Suite has estimated that 1-chloro-3-nitrobenzene is expected to be found not predominantly in soil and its not persistence estimate is based on its transformation in this medium. Its half-life in soil, 75 days (1800 hrs), does not exceeds the threshold of 120 days as per Annex XIII of REACH.

Therefore, 1-chloro-3-nitrobenzene is estimated to be not persistent in the soil environment.
