Description of key information

Measured data are not available for ethylene for this endpoint. Ethylene is a gas at standard temperature and pressure and is expected to partition primarily to air, therefore aquatic toxicity tests may not be relevant. In addition, it is technically difficult to maintain aqueous concentrations of gases for toxicity testing. Two QSAR models have been used to estimate the short term toxicity to invertebrates:

ECOWIN v1 ECOSAR (Nabholz and Mayo-Bean 2009) calculated a 48 -hour EC50 for daphnia of 62.48 mg/L.

The Target Lipid Model (Mcgrath et al., 2004) calculated an LL50 of 215 mg/L.
