Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Chemicals can reach the soil via several routes:

1.                 Application of sewage sludge in agriculture.

Organic peroxides, when released into the sewage of a production plant 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 in most cases.

From the production plant, the release of organic peroxide into the sewage is very limited, not to say completely negligible. The waste water from production plant is usually treated: at least a physical/chemical treatment, which will neutralize potential residual organic peroxide, and that can be followed by a biological treatment. So it is expected that organic peroxides will be present in sludge only at low concentrations.

Regarding the rest of the lifecycle, organic peroxides are mainly used as cross-linking agent/polymerization initiator for the production of resins/rubbers/polymers. Based upon the fact that organic peroxides are totally consumed during the process (>99%) and that those processes are water-free (so no production of sewage sludge), it is assumed that the soil is not exposed to organic peroxides via use of sludge.

As a consequence, we can assume that exposure of soil to organic peroxides is negligible via the application of sewage sludge in agriculture.

2.                 Direct application of chemicals.

Based on the uses inventoried for organic peroxides we can consider that there is no direct application of these substances on the soil compartment. Hereunder, the relevant Environmental Release Categories (ERC), as described in guidance R12 (version 2.0, dated 7/11/2010)

3.                 Deposition from the atmosphere.

Deposition from the atmospheric compartment involves volatilization, vaporization or direct release of a considered substance into the atmosphere. Due to their dangerous intrinsic physico-chemical properties, organic peroxides are carefully handled in closed systems and their transport and production are ruled by several regulations. Based on organic peroxides uses too, emission to air is controlled and deposition to soil from the atmosphere is at safe levels.

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