Distribution of benzo (a) pyrene (BaP) in soil in urban area was investigated with a simple micro-analytical method consisting of ultrasonic extraction, one-dimensional dual band thin-layer chromatography (TLC) and spectrofluorometric determination. The TLC was done in the following condition; Thin-layer plate; Kieselguhr G (4×20 cm)-(26% Acetylated cellulose+Cellulose Avicel SF) (95: 5, w/w, 11×20cm), Developer; Methanol-ether-water (4: 4: 1 v/v).<BR>The results thus obtained were as follows:<BR>1) All samples collected from v arious areas were contained BaP.<BR>2) BaP contents in soils obtained from industrial areas were much higher than those in soils from commercial and residential areas. The contents were 170-6030 ppb in industrial area, 90-4190 ppb in commercial area and 10-1150 ppb in residential area.<BR>3) BaP contents in soils from principal roads were far higher than those from side roads and parks even when side roads and parks located near a principal road. These findings suggest strongly that soils in urban area are polluted by BaP emitted by automobiles.
