Description of key information

Additional information

The substance was tested for chronic toxicity to earthworms in a Klimisch 1 GLP study; the overall NOEC for reproduction, mortality, growth and food consumption was equal or greater than the highest test concentration, i.e. >= 104 mg/kg dw. No other tests on terrestrial species have been performed at the moment.

The Guidance on information requirements and chemical safety assessment, Chapter R.7C: Endpoint specific guidance (May 2008), section R., Table R.7.11-2, page 131, specifies the information needed to waive the terrestrial studies based on soil hazard categories.

The registered substance has a log Pow <3 and exhibits a good potential for inherent biodegradability. Therefore, accumulation and persistence of the registered substance in soil and organisms is very unlikely. Furthermore, although the registered substance might adsorb to soil (estimated log Koc = 3.8), it is not expected to cause adverse effects on terrestrial organisms based on a PNEC soil derived from a chronic earthworm study. 

The result is considered relevant and reliable for the risk assessment. Consequently further terrestrial toxicity tests are not needed.
