The levels of sediments and mosses (PAHs) and trace elemental composition of runoff and associated sediments and road side moss samples, Barbula lambarenesis (p.vard) were determined by Gas-liquid chromatography- mass spectrometry (GC_MS), Atomic absorption (AAS) and capillary Electrophoresis n(CE) techniques. The aims of the study were to develop a simple and efficient procedure for the GC_MS measurement and identification of PAHs in surface runoffs, sediments and mosses of Lagos, Ile-Ife and Osogbo areas determine areas
