Method/Apparatus/Procedure:
Flasks containing 500 mL of water and (1) were placed in a constant temperature (± 0.1 °C) gyrotary shaker (200 rpm) for at least 24 h. Following a 12 h stationary equilibration period, 100 mL of saturated solution was drained through a glass-wool plug into a separatory funnel. Acenaphthene was isolated from solution by triplicate extraction with 10 mL of hexane, which recovered over 99% of hydrocarbon as determined in experiments with spiked solutions. Acenaphthene levels in concentrated extracts were determined on a Hewlett-Packard Model 5840A gas chromatograph using a WCOTSP-2100 glass column (30 m x 0.25 mm i.d.). Hydrocarbon concentrations in extracts were additionally determined by ultraviolet spectrophotometry. Agreement was typically within 2%. Further details are given in the paper.

Experimental Data
The solubility of acenaphthene in distilled water at 25°C was reported to be 2.42 µg/g, corresponding to a mole fraction, x1, of 1.6 × 10-8. The corresponding mass per cent calculated by the compiler is 2.42 × 10-4 g(1)/100 g sln.
