Description of key information

Not toxic for the three environmental thophic levels.

Additional information

Acute short-term administration on invertebrates:

The assessment is based on a single study made in 2017 and conducted according to OECD guideline 202.
This study was performed in according to the GLP Principles. The acute toxicity to Daphnia magna was determined during a 48 hour static test.

Under test conditions the test article was sufficiently stable and shows the following values:

EC50(48h) > 100 mg/l

Acute short-term administration on aquatic plants.

The test perfromed according to OECD 221, acute toxicity to aquatic plants (Lemna minor) does not show any effect.

The EC50 growth rate related to frond numbers is 392 mg/l.

The test substance is very soluble in pure (deionised) water and none sedimentation has been observed during the tests.

According to the CLP Regulation (EC 1272/2008), acute aquatic toxicity is normally determined using a fish 96-hour LC50, a crustacean species 48-hour EC50 and/or an algal species 72- or 96-hour EC50; nevertheless it is also specified in the Regulation that data on other species (e. g. Lemna spp.) shall also be considered if the test methodology is suitable. These species cover a range of trophic levels and are considered as surrogate for all aquatic organisms.

According to the table 4.1.0 of the CLP Regulation (EC n. 1272/2008), asubstance for wich adequate chronic toxicity data are not available shall be classified as

Aquatic Acute 1 when:

96 hr LC50 (for fish)1 mg/l and/or

48 hr EC50 (for crustacea)≤1mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)1 mg/l

Aquatic Chronic 1 when:

96 hr LC50 (for fish)1 mg/l and/or

48 hr EC50 (for crustacea)≤1mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)1 mg/l

Aquatic Chronic 2 when:

96 hr LC50 (for fish) > 1 <= 10 mg/l and/or

48 hr EC50 (for crustacea)> 1 <= 10 mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)> 1 <= 10 mg/l

Aquatic Chronic 3 when:

96 hr LC50 (for fish) > 10 <= 100 mg/l and/or

48 hr EC50 (for crustacea)> 10 <= 100 mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)> 10 <= 100 mg/l

and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)

Taking into account the information available for the target substance, no classification is warranted based on Regulation CE 1272/2008.
