Further biotic degradation testing shall be proposed by the registrant
if the chemical safety assessment according to Annex I indicates the
need to investigate further the degradation of the substance and its
degradation products. The choice of the appropriate test(s) depends on
the results of the chemical safety assessment and may include simulation
testing in appropriate media (e.g. water, sediment or soil). Exposure of
the soil compartment is unlikely, that is the reason why we don't
propose a simulation biodegradation tests in soil.
Chemicals can reach the soil via several routes:
of sewage sludge in agriculture.
Organic peroxides, 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 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 are present only at very
lowconcentrations in sludge.
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
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
3. 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 handle in closed systems and
their transport and production are ruled by several regulations. Based
on organic peroxides uses too, we may assume that deposition on soil
from the atmosphere is unexpected.
