The root, shoot and total biomass and chlorophyll a, chlorophyll b and total chlorophyll were significantly reduced up to a distance of 4 km from the source of pollution. The data indicates that the degree of response increased with decreasing distance from the source of pollution in comparison to the reference site ¡®c' situated at 20 km. Biomass and chlorophyll pigments showed a significant and positive relationship with the distance from the source. Key words : Air pollution, Brassica juncea , biomass, chlorophyll.   doi: 10.3126/eco.v15i0.1935 ECOPRINT 15: 1-6, 2008
