Chemicals can reach the soil via several routes:


1.                 Application of sewage sludge in agriculture.


Ethyldiisopropylamine (EDIPA) when released into the sewage of a plant production or of a downstream’s user plant, are treated with other substances in dedicated sewage treatment plants. The activated sludge stemmed from these sewage treatment plants are then extracted and treated as chemical waste. Industrial sludge are not applied natural soils. The sludge are incinerated, contained or reclaimed.


From the production plant, the release of EDIPA into the sewage is very limited, not to say completely negligible. So it is expected that EDIPA won’t be present in sludge.


EDIPA is mainly used as reactive processing aid and intermediate.


As a consequence, we can assume that soil is not exposed to EDIPA via the application of sewage sludge in agriculture.


2.                 Direct application of chemicals.


Based on the uses inventoried for EDIPA we can consider that there is no direct application of these substances on the soil compartment. Indeed, all uses are within industrial settings.


3.                 Deposition from the atmosphere.


Deposition from the atmospheric compartment involves volatilization, vaporization or direct release of a considered substance into the atmosphere. On plant production and on downstream's user plant, releases to atmosphere are controlled. The main releases are fugitive releases and are considered negligible. Thus we may assume that deposition on soil from the atmosphere is unexpected.


 


Based on these arguments no test is proposed for the soil compartment.
