Abstract

The solubility of benzo(a)pyrene (BaP) in water is small, and measured total BaP concentration (t-BaP) in fresh water is the sum of BaP dissolved in water (d-BaP) and BaP adsorbed to suspended solids (p-BaP). We have collected fresh water samples in a lake and rivers in Okayama Prefecture, Japan, and measured both d-BaP and p-BaP in each sample. The blue rayon method or solid-liquid extraction was used for extraction of BaP in water or in suspended solids, respectively. The measurement of BaP was done using high-performance liquid chromatography according to our previously reported method. The present data indicate that p-BaP was about 1.5 to 5 times higher than d-BaP. In general, the amount of suspended solids in each sample did not show a correlation to p-BaP. These results suggest that BaP adsorbed to suspended solids must be taken into account when assessment of t-BaP is done in any given fresh water sample. (C) 2000 John Wiley and Sons, Inc.
