Description of key information

One activated sludge respiration inhibition test is available with a soluble aluminium salt. This test was performed with aluminum chloride CAS RN 7446-70-0 according to standard guideline. No effects were seen up to the highest test concentration of 1000 mg/l test material. The test substance contained 20 g Al/100 g and the test concentrations can be converted to mg/l Al. 1000 mg/l test material is equal to 200 mg/l Al. See Table # "Toxicity to aquatic micro-organisms" (above).

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
