Additional information

Acute and chronic data of reliability 1 or 2 (Klimisch rating), based on international guidelines, are available for three trophic levels: Algae, Invertebrates and Fish. The results are summarized in the table below.

Organism	EC₅₀/LC₅₀(mg/L)	EC₁₀/NOEC (mg/L)	Flag / reliability	Reference in IUCLID
Acute
Aquatic algae (acute and chronic data)
Pseudokirchneriella subspicatus	72h: 0.736	72h: 0.162	K/2	CHIMEXANE NB, Toxicity to aquatic algae, Scheerbaum, 2009, RS, K
Aquatic invertebrates
Daphnia magna	48h: 3.8	-	K/2	CHIMEXANE NB, Short-term toxicity to aquatic invertebrates, Noack, 2009, RS, K
Fish
Oncorhynchus mykiss	96h: >0.927	-	K/2	CHIMEXANE NB, Short-term toxicity to fish, Scheerbaum, 2010, RS, K
Micro-organisms
Activated sludge	3h: >1000	3h: 1000	K/2	CHIMEXANE NB, Toxicity to microorganisms, Fiebig, 2010, RS, K
Chronic
Aquatic invertebrates
Daphnia magna	-	21d: 0.266	K/1	CHIMEXANE NB, Long-term toxicity to aquatic invertebrates, Noack, 2010, RS, K
Fish
Oncorhynchus mykiss	-	28d: ≥ 0.868	K/1	CHIMEXANE NB, Long-term toxicity to fish, Scheerbaum, 2010, RS, K

Among all data available, the algae Pseudokirchneriella subspicatus seems to be the most sensitive species in acute and chronic exposure with a 72h-ErC50 at 0.736 mg/L and a 72h-ErC10 at 0.162 mg/L.
