0%
yes
The dissolved oxygen concentration must have been at least 60 per cent of the air
saturation value throughout the test
Not indicted in test report.
There must be evidence that the concentration of the substance being tested has been satisfactorily maintained, and preferably it should be at least 80% of the
nominal concentration throughout the test. If the deviation from the nominal
concentration is greater than 20%, results should be based on the measured
concentration.

Initially conducted at 2 WAF concentrations (100 and 1000 mg/L). An additional vessel with a nominal 10 mg/L WAF was prepared.

WAF test solutions were prepared by dilutions of a nominal 1000 mg/L. The stock was prepared by combining 22 g of the test substance with 22 liters
of dilution water in mixing vessels with magnetic stirrers. The mixtures were stirred for 24 hours and allowed to settle for approximately 1 hour. Water for dilutions was obtained by syphoning. - Test organisms (species):

Additional information
One study is available on the short-term toxicity of Bis(2-(2-butoxyethoxy)ethyl) adipate (CAS 141-17-3) to fish.
This key study was performed according to OECD Guideline 203 (Sewell, 1992). The test organism Oncorhynchus mykiss was exposed to nominal concentrations of 10, 18, 32, 56 and 100 mg/L for 96 hours. Mortality occurred at all test concentrations except the lowest, and a LC50 of 13 mg/L (nominal) was calculated.
