✦ Synopsis

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