The rising global concern on air pollution in particular for toxic pollutants give rise to the needs and requirements for their monitoring in ambient air and the associated new analytical methods developed for their monitoring and environmental impact assessment. As the control limit for toxic pollutants are extremely low, sample cleanup and analyte enrichment are required prior to their determination.
