The great change in the water level of the Mekong River in each season creates the variation in many environmental factors including polycyclic aromatic hydrocarbons (PAHs). Seasonal monitoring of PAHs in water samples from 10 sampling stations along Thai/Laos Mekong River in April 2003- January 2004 from Golden Triangle to Kongchiam were analysed. Quantative analysis of the 16 priority PAHs namely: naphthylene, acenaphthylene, acenaphthene, fluorene, phenathrene, anthracene, flouranthene, pyrene, benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenzo[a,h]anthracene, benzo[g,h,i]perylene and indeno[1,2,3,cd]pyrene were performed.
