Additional information

The EU RAR (ECB 2007) discusses two studies on the toxicity of ethylbenzene to earthworms (Callahan et al 1994 and Neuhauser et al 1985) but neither study was considered sufficiently reliable for use in the regulatory documents and so the results have not been presented here. The Draft Screening Assessment Report (Environment Canada 2014) also discusses Neuhauser et al (1985), but this used filter paper as a substrate rather than actual soil. The Draft Screening Assessment Report (Environment Canada 2014) reports a 14 day NOEC for earthworms of 16 mg/kg dw from ESG International (2002).
