towards terrestrial organisms should be proposed by the registrant if
the chemical safety assessment indicates the need to further investigate
the effects on terrestrial organisms. Annex IX of Regulation 1907/2006
states that, in the absence of toxicity data for terrestrial organisms,
the equilibrium partitioning method (EPM) may be applied to assess the
hazard to terrestrial organisms. The results of the chemical safety
assessment indicate that potential exposure would not be expected to
result in an unacceptable level of risk for the terrestrial compartment.
Therefore, no specific testing is required to assess the toxicity of the
substance to terrestrial organisms.
there is no wide dispersive use as the chemical is only used in
industrial processes. From industrial processes, the release of 4-MHHPA
into the sewage is very limited, if not completely negligible, as the
chemical is incorporated into a matrix during polymer manufacturing, In
the unlikely case that 4-MHHPA will reach sewage, the anhydride group,
which represents the single reactive and toxic functional moiety,
rapidly hydrolyses to the respective di-acid. Overall, it is expected
that 4-MHHPA will not be present in sewage sludge, will not be
distributed to sediment, and direct or indirect exposures of the aquatic
and terrestrial compartments are unlikely
