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
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
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 won’t be
present 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 soil is not exposed to organic peroxides via the application of
sewage sludge in agriculture.
application of chemicals.
Based on the uses inventoried for
organic peroxides we can consider that there isno direct application
of these substances on the soil compartment. Hereunder, the relevant

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
thatdeposition on soil from the atmosphere is unexpected.
