Column 2 criteria for aquatic microorganisms toxicity testing of
ethylbenzene provide the following adaptations:
The study does not need to be
is no emission to a sewage treatment plant, or
are mitigating factors indicating that microbial toxicity is unlikely to
occur, for instance the substance is highly insoluble in water, or
substance is found to be readily biodegradable and the applied test
concentrations are in the range of concentrations that can be expected
in the influent of a sewage treatment plant.
Ethylbenzene is a volatile chemical with
the low tendency to adsorb to solid matter (logKoc<4).
A screening level
Sewage Treatment Plant (SRP) Fugacity Model was used by the registrant
to assess the fate of ethylbenzene in the activated sludge sewage
treatment plant (STPWIN programme). The model estimates the fate of a
chemical present in the influent as it becomes subject to removal by
evaporation, biodegradation or another degradation processes, sorption
to sludge, and loss in the final effluent.
The model results suggest that most of
ethylbenzene will be removed from the STP. Moreover, ethylbenzene will
not absorb to sewage sludge. Therefore, it is considered that microbial
toxicity due to exposure to ethylbenzene is not likely to occur within
