The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Niederlehner et al (1998) followed a standard guideline to determine the reproductive toxicity of benzene to Ceriodaphnia dubia. The exposure concentrations were monitored and a 7 days NOEC of 38 uM was reported. This equates to a NOEC of 3 mg/L. This value was also the most conservative chronic endpoint for invertebrates identified in the EU RAR for benzene (2008).
