Information on the environmental fate of
EDTA-FeNa.3H2O is largely based on available information for EDTA and a
number of its salts (e.g. EDTA-Na4, EDTA-Na2H2, EDTA-CaNa2). A
justification for the read-across between these substances and
EDTA-FeNa.3H2O is provided in a document attached to IUCLID section 13.
EDTA-FeNa.3H2O is expected to be resistant
to hydrolysis, neither strong acids nor alkalis cause any degradation.
Several studies show that Fe(III)-EDTA is photodegraded in natural
water. Due to its low log Kow, the substance does not significantly
bioaccumulate in organisms. Based on the low log Kow together with the
ionic structure of the substance under environmentally relevant
conditions, no adsorption onto the organic fraction of sediments is
expected. A large number of degradation tests are available for EDTA and
its salts. These tests show that EDTA is not readily biodegradable under
the conditions of standard ready biodegradability tests. It was shown
that under special conditions, like
adaptation or slightly alkaline pH, which is realistic under
environmental surface water conditions, the biodegradability of EDTA is
considerable enhanced. Therefore it can be concluded that EDTA is
ultimately biodegradable under such environmental conditions.
EDTA-FeNa.3H2O is not biodegradable in
slightly acidic soils.It should, however, be noted that in surface
water, it was shown that under special conditions like adaptation or
slightly alkaline pH, which is realistic under environmental surface
water conditions, the biodegradability of EDTA is considerably enhanced.
Therefore, it can be concluded that EDTA is ultimately biodegradable
under such environmental conditions. Based on its low log
Kow, EDTA-FeNa.3H2O is not Bioaccumulative (not B).
