Toxicity to microorganisms, 2008, Clarke, RS, K

Among data available, the fish, Brachydanio rerio, is the most sensitive species with a 96h-LC50 at 13.1 mg/L. For aquatic invertebrates, the 48h-EC50 was determined at 15 mg/L. For algae, the 72h-EC50 value was determined at 20 mg/L (based on growth rate). For microorganisms, the 3h-EC50 and 3h-NOEC values were determined at 700 mg/L and 180 mg/L respectively.
