The present study endeavours to explore the role of vegetation in air quality improvement at selected sites of Delhi. The study was conducted at four sites of Delhi-Pusa in Central Delhi, ITO in East Delhi, Dwarka in South West Delhi and Rohini in North West Delhi. To monitor and quantify the abundance, frequency and density of vegetation of the sites,belt transect method (with 500m transect and 30 quadrats of 0.5 x 0.5m) was used. Results of the study indicate that Pusa had highest abundance(6.7), frequency(86%) and density(6.2) of vegetation as compared to Dwarka, Rohini and ITO. ITO site has minimum abundance (2.0), frequency (50%) and density (1.9) of vegetation. There was a statistically negative correlation between the abundance, frequency and density of vegetation and ambient levels of chemical air pollutants. Physical pollutant (PM 2.5), doesn’t seem to get affected by vegetation. The study indicates that the contribution of vegetation is significant in improving air quality of urban areas.

Abstract


The present study endeavours to explore the role of vegetation in air quality improvement at selected sites of Delhi. The study was conducted at four sites of Delhi-Pusa in Central Delhi, ITO in East Delhi, Dwarka in South West Delhi and Rohini in North West Delhi. To monitor and quantify the abundance, frequency and density of vegetation of the sites,belt transect method (with 500m transect and 30 quadrats of 0.5 x 0.5m) was used. Results of the study indicate that Pusa had highest abundance(6.7), frequency(86%) and density(6.2) of vegetation as compared to Dwarka, Rohini and ITO. ITO site has minimum abundance (2.0), frequency (50%) and density (1.9) of vegetation. There was a statistically negative correlation between the abundance, frequency and density of vegetation and ambient levels of chemical air pollutants. Physical pollutant (PM 2.5), doesn’t seem to get affected by vegetation. The study indicates that the contribution of vegetation is significant in improving air quality of urban areas.
