The present study was undertaken to work out the impact of vehicular pollution on the pigment content of four plant species, namely Cassia fistula, Eucalyptus citriodora, Ficus religiosa and Mangifera indica growing along the road side of highways at Raipur. For study, leaf samples from different sites of the above referred species were collected and analyzed for chlorophyll a, b, and carotenoids content. Leaves were sampled from all the four directions and from almost equal heights of the plants. Primary air pollutants (SO2, NOx, SPM and RSPM) were also assessed at three different study sites. It was observed that chlorophyll ‘a’ and chlorophyll ‘b’ content varied from 0.98 mg/g to 1.72 mg/g and 0.54 mg/g to 1.10 mg/g respectively at the studied sites. Carotenoid content ranged from 1.02 mg/g to 1.62 mg/g at the study sites. Results clearly indicate that the pigment content is affected & reduce with the increase in air pollution.
