Additional information

In a set of experiments designed to generate a dataset for the development of a QSAR model, the toxicity of 2 -(2 -ethoxyethoxy)ethanol ether to the algae P subcapitata was assessed using a modified guideline protocol modified to increase throughput and to cope with sealed systems to allow testing of volatile substances. The measured EC50 was 14861mg/L.
