Method/Apparatus/Procedure:
The method consisted of preparing serial dilutions of a suspension of [1] in [2] and determining nephelometrically the amount of [1] per unit volume beyond which further dilution caused no reduction in light scattering, which remained equal to that of pure [2]. A Bausch and Lomb Dubosque colorimeter model 100-mm was employed. Many details are reported in [1].
Source and Purity of Materials:
- Prepared at Harvard University;; MP = 161.4-161.8°C (cf. [2]).
- Dust-free
Estimated Errors:
Ambient temperature: ±3°C
Mass concentration (m/v) (1): ±0.1 × 10-5 g(1) dm-3 (2)

Components:
- Benz(a)anthracene, $\ce{ C18H12 }$; [56-55-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The best value recommended by the authors is 1.1 × 10-5 g(1) L-1 (2).
Assuming that 1.00 L sln = 1.00 kg sln, the corresponding mass percent and mole fraction calculated by the compiler are 1.1 × 10-6 g(1)/100 g sln and 8.7 × 10-10.
