Additional information
A number of studies have been carried out to assess the toxicity of 2 -(2 -butoxyethoxy)ethanol to micro-organism using multiple species in fresh water. These studies that are reliable indicate that the substance is practically non-toxic to micro-organisms. One study reported lower toxicity threshold to one particular species than the value chosen as the key parameter. Since this study was performed over a longer period than is usual, its use is likely to over-estimate the toxicity of the substance. They key parameter is selected from a study to assess the toxicity to micro-organisms; activated sludge was exposed to 2 -(2 -butoxyethoxy)ethanol at nominal concentrations and under static conditions. No respiration inhibition was observed up to the maximum tested concentration of 1995mg/l. Based on the results of this study, this substance has low toxicity to bacteria or waste water treatment systems.
