摘要：

We report first attempts of applying laser multiphoton ionization to analysis of trace pollutants in environmental samples, including soils, aerosols and ambient air. A fast conductivity technique was developed for such on-line analysis and was applied to several (organic and inorganic) environmental samples. Matrix effects were investigated and compensation methods were suggested. Limits of detection in the ppb range are reported for polycyclic aromatic hydrocarbons (PAH) compounds.
