Assessment of aquatic toxicity:
There is a high probability that the product is not acutely harmful to aquatic organisms. Based on
long-term (chronic) toxicity study data, the product is very likely not harmful to aquatic organisms.
The inhibition of the degradation activity of activated sludge is not anticipated when introduced to
biological treatment plants in appropriate low concentrations.
Toxicity to fish:
LC50 (96 h) 1,474 mg/l, Oncorhynchus mykiss (OECD Guideline 203, static)
Nominal concentration. Literature data Aquatic invertebrates:
EC50 (48 h) 1,550 mg/l, Daphnia magna (OECD Guideline 202, part 1, static)
Nominal concentration. Literature data.
Aquatic plants:
EC50 (72 h) 1,840 mg/l (growth rate), Pseudokirchneriella subcapitata (OECD Guideline 201, static)
Nominal concentration. Literature data.
Microorganisms/Effect on activated sludge:
Toxic limit concentration (16 h) > 700 mg/l, Pseudomonas putida (DIN 38412 Part 8, static)
Nominal concentration. Literature data.
Chronic toxicity to fish:
No observed effect concentration (21 d) > 100 mg/l, Brachydanio rerio (OECD Guideline 204,
semistatic)
Nominal concentration. Literature data. Limit concentration test only (LIMIT test).
Chronic toxicity to aquatic invertebrates:
No observed effect concentration (21 d), 100 mg/l, Daphnia magna (OECD Guideline 211,
semistatic)
Nominal concentration. Literature data.
Assessment of terrestrial toxicity:
No data available concerning terrestrial toxicity.
