It has been found that vanadium serves as a suitable indicator to evaluate urban air quality. Since vanadium in suspended particulate matters mainly comes from use of fossil fuel, it effectively indicates the influence of human activities on environmental quality of urban atmosphere. The concentration of this element in air samples ranges 10-9-10-8g/m3. Both of graphite furnace atomic absorption spectrophotometry and inductively coupled plasma emission spectrometry lack the required sensitivity and selectivity for those measurements. In this study, ion-pair reversed-phase partition high performance liquid chromatography has been successfully applied to the trace vanadium at ng/m3 level in air. No interference from the complex matrix of airborn-particulates was observed . Determination of vanadium in the suspended particulate matters in Sendai City by the use of the proposed technique has been performed to prove the validity of this element as a sensitive indicator for urban environment.
