Description of key information

Additional information

Toxicity to fish, aquatic invertebrates, and algae: 

Experimental short-term fish, invertebrate, and algae data for the registered substance exhibit low (LC50 >10 <=100 mg/L) acute aquatic toxicity. Experimental long-term invertebrate data for the registered substance exhibit moderate chronic aquatic toxicity >0.1 and <=1.0 mg/L.

 Supporting information is provided by acute and chronic aquatic toxicity values calculated using the neutral organics structure-activity relationship in the ECOSAR computer program (Nabholz and Mayo-Bean, 2009) of EPISuite. Validity and applicability of the QSAR are described in a document attached as background material to the QSAR endpoint study record.

 These measured data demonstrate that the QSAR estimations accurately predict aquatic effects from short and long-term continuous exposure to the registered substance (as is obtained under test conditions).

 Toxicity to microorganisms:

 Results from an aerobic respiration study, using an activated sludge inoculum, suggests that the registered substance would not produce effects to aquatic micro-organisms.
