ABIOTIC DEGRADATION IN AIR

DIRECT PHOTOLYSIS in air
EC substance [940-223-9] does not absorb light >290 nm (ozone band) and therefore a direct photolysis in air will not occur.

INDIRECT PHOTOLYSIS in air

OH radical induced indirect photolysis of EC substance [940-223-9] can be estimated with US EPA AOPWIN Program resulting in a low degradation half-life of 0.3d (12h day). But as EC substance [940-223-9] has a low Henry’s Law Constant of  8*10-14 Pa*m3/mole, volatilisation is not an exposure route which has to be considered. 

 

ABIOTIC DEGRADATION IN WATER


HYDROLYSIS

The amide group of EC substance [940-223-9] cannot be hydrolyzed rapidly under environmental conditions as stated in OECD Guideline 111. In addition EC SUBSTANCE [940-223-9] is readily biodegradable.

 

DIRECT PHOTOLYSIS in water
EC substance [940-223-9] does not absorb light >290 nm (ozone band) and therefore a direct photolysis in water will not occur.

INDIRECT PHOTOLYSIS in water

OH radical induced indirect photolysis of EC substance [940-223-9] can be estimated with US EPA AOPWIN Program resulting in a low degradation half-life of 0.3d (12h day). EC substance [940-223-9] may therefore be degraded in water by indirect photolysis if sufficient OH radicals are available. As EC SUBSTANCE [940-223-9] is rapidly biodegraded in surface water (see IUCLID Section 5.2.2) indirect photolysis will play a minor role in degradation.

 

ABIOTIC DEGRADATION IN SOIL

 

DIRECT PHOTOLYSIS in soil

EC substance [940-223-9] does not absorb light >290 nm (ozone band) and therefore a direct photolysis in soil will not occur.

INDIRECT PHOTOLYSIS in soil

OH radical induced indirect photolysis of EC substance [940-223-9] can be estimated with US EPA AOPWIN Program resulting in a low degradation half-life of 0.3d (12h day). EC substance [940-223-9] may therefore be degraded in soil by indirect photolysis if sufficient OH radicals are available. As EC SUBSTANCE [940-223-9] is rapidly biodegraded in aerobic soils (see IUCLID Section 5.2.3) indirect photolysis will play a minor role in degradation.
