Description of key information
Additional information
Biotic degradation
Based on the ThODNH4 the percentage biodegradation of Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioate reached 30% after 28 days of incubation.
Since the biodegradation of the test item did not reach the pass criterion of 60% degradation and no 10 day-window could be determined, the validity criterion for ready biodegradation was not applicable. Therefore, Reaction mass of sodium sulfate,sodium amino-12-dodecanoate and sodium dodecanoedioate is considered not to be readily biodegradable but a potential of inherent biodegradability can be assumed.
The reaction mass is produced at one manufacturing site and is then used by the paper industry for the production of paper by the Kraft process.
At the manufacturing site, exposure to the substance via releases to the aquatic compartment is very limited. During the concentration step of the reaction mass, water is removed to concentrate the inorganic and organic salts. Release to the aquatic compartment would be possible from this water resulting from this concentration step. Thus based on the process, the wastewater would contain a very limited amount of the reaction mass and is treated by the on-site sewage treatment plant thus resulting in a non significant exposure of the aquatic compartment to the reaction mass.
The use of the reaction mass by the paper industry is done in a closed system where it is entirely consumed during the Kraft process. Thus the use of the substance by the paper industry results in no exposure of the environment to the reaction mass.
For these reasons, no test is proposed in order to further assess the degradation potential of the concerned substance in soil and sediments.
Abiotic degradation
Abiotic degradation was not assessed because the different components of the concerned reaction mass are not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups. Besides, an experimental determination and quantification of the degradation products if some appear would be technically really difficult. Last but not the least, due to the pH of the tested reaction mass, if there was a potential for abiotic degradation, the alkaline hydrolysis would already be done.
Bioaccumulation
The reaction mass is produced at one manufacturing site and is then used by the paper industry for the production of paper by the Kraft process.
At the manufacturing site, exposure to the substance via releases to the aquatic compartment is very limited. During the concentration step of the reaction mass, water is removed to concentrate the inorganic and organic salts. Release to the aquatic compartment would be possible from this water resulting from this concentration step. Thus based on the process, the wastewater would contain a very limited amount of the reaction mass and is treated by the on-site sewage treatment plant thus resulting in a non significant exposure of the aquatic compartment to the reaction mass.
The use of the reaction mass by the paper industry is done in a closed system where it is entirely consumed during the Kraft process. Thus the use of the substance by the paper industry results in no exposure of the environment to the reaction mass.
As a consequence, it can be assumed that the substance will not bioaccumulate in trophic chains.
Adsorption
The experimental results indicate a moderate potential of the concerned substance to adsorb on soil and sediments. The reaction mass is produced at one manufacturing site and is then used by the paper industry for the production of paper by the Kraft process.
At the manufacturing site, exposure to the substance via releases to the aquatic compartment is very limited. During the concentration step of the reaction mass, water is removed to concentrate the inorganic and organic salts. Release to the aquatic compartment would be possible from this water resulting from this concentration step. Thus based on the process, the wastewater would contain a very limited amount of the reaction mass and is treated by the on-site sewage treatment plant thus resulting in a non significant exposure of the aquatic compartment to the reaction mass.
