Description of key information
Additional information
Substance is only used in industrial settings (manufacture, and downstream use) with no wide dispersive uses. We propose to waive all soil tests as there is no exposure to soil compartment
Chemicals can reach the soil via 3 main routes:
1. Application of sewage sludge in agriculture.
a. Manufacture/formulation:
Waste water from the production plant is generally treated on site (at least a physical/chemical treatment, which will neutralize potential residual organic peroxide). This is usually followed by a dedicated onsite biological treatment. The activated sludge originating from these sewage treatment plants is then extracted and treated as chemical waste
b. Downstream use:
Due to their reactive and explosive nature, organic peroxides are generally handled under very strict industrial conditions. They are mainly used as cross-linking agents/polymerization initiators for the production of resins/rubbers/polymers. Based upon the fact that organic peroxides are totally consumed during the process (>99%, which is confirmed by the release factor to sewage for curing agents (Emission Scenario Document on Plastic Additives: ENV/JM/MONO(2004)8/REV1, July 2009, Sections 17.1 and 17.2), it is assumed that the soil is not exposed to organic peroxides via use of sludge.
As a consequence, we can assume that soil is not exposed to organic peroxides via the application of sewage sludge in agriculture.
2. Direct application of chemicals.
Based on the inventory of uses of organic peroxides, 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. Due to their dangerous intrinsic physico-chemical properties, organic peroxides are carefully handled in (semi-)closed systems and their transport, production and use are ruled by several regulations. This is also in line with the release factor to atmosphere for curing agents (Emission Scenario Document on Plastic Additives: ENV/JM/MONO(2004)8/REV1, July 2009, Sections 17.1 and 17.2). Based on their uses, we assume that deposition on soil from the atmosphere is unexpected.
Based on these arguments no test is proposed for the soil compartment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
