EC number: 211-334-3
CAS number: 638-38-0
Lemna Growth Inhibition: EC50 (4d) = 96 mg/L Manganese (II) acetate (corrected value) for Lemna minor (equivalent to OECD 221, static)
The testing was performed similar to
OECD guideline 221, the documentation and given results indicate that
the study was well-performed and satisfies general scientific
requirements. So the study is classified as reliable with restrictions
and consequently, the results can be considered to be reliable.
Additionally, the test organism Lemna minor broadens the spectrum of
aquatic organisms and, as an additional model, allows a deeper insight
in the expectable effects of the test substance on the aquatic
environment. Therefore, these results should be also taken into account
when assessing the need for classification. The prevalent study was
consequently considered to suitable to support the results from IUCLID
endpoint 6.1.5 "Toxicity to aquatic algae and cyanobacteria" and the
non-classification: A 4 d EC50 value of 31 mg/L Mn2+, corresponding to
96 mg/L Manganese (II) acetate, was obtained. Taking into account that
Manganese (II) acetate as an inorganic salt has no potential for
bioaccumulation, Manganese (II) acetate does not need to be classified
as harmful to the aquatic environment, based on the effects on Duckweed,
according to regulation 1272/2008/EC. This conclusion is congruent to
the results obtained in the testing for aquatic algae toxicity.
