Test solutions
- Vehicle:
- no
- Details on test solutions:
- Water accommodated fractions prepared per methods described in OSPAR 1995. Soltex Additive was prepared in dilution water, shaken vigorously, and allowed to stand for 4 hours. A cloudy dark brown solution with neutrally buoyant material was observed. For each nominal concentration, the required amount of homogenized sample was added to 12 L of dilution water (artificial seawater), mixed for 20-24 hours, allowed to separate for 4 hours, and filtered using a 0.63 micron sieve. The filtrate was used to prepare the test solutions, which were 560, 1000, and 1800 mg/L nominal. It was observed that more test material settled during the test from 24 hours onward. The dissolved concentrations were likely to be lower than the nominal concentrations as Soltex Additive was poorly soluble in water.
Test solutions were replaced at 48 hours (semi-static exposure).
