The lowest toxicity value is the 96 -hours EC50 (growth rate) for algae (Pseudokirchnerella subcapitata), 0.24 mg/l (NOEC of 0.0079 mg/l), as per OECD 201, triggering Clearlink 1000 to be classified as aquatic acute hazard class 1. The aquatic short-term toxicity EC50 (48 h, immobilisation) to invertebrates (Daphnia magna) is 27 mg/l (EPA 40 CFR 767.1300), and the LC50 (96 h, mortality) to fish (Oncorhynchus mykiss) is > 570 mg/l (EPA 40 CFR 767.1300).
