ABSTRACT

 

Pollution of the environment with toxic metals has increased dramatically since onset of the industrial revolution. Although heavy metals are naturally present in soil as the contaminants and comes from local sources mostly from industries. The aim of present study was to know the accumulation of heavy metals in plant’s leaves and their effects on total photosynthetic pigments of plants growing under industrial pollution. In present study the accumulation of heavy metals like Pb, Cd, Cu and Ni in the leaves of naturally growing plants i.e. A. indica (Neem), C. gigantean (Aak), D. sissoo (Shishum), E. jambolana (Jamun), M. indica (Aam), N. indicum (Kaner) of Pithampur Industrial area sector-1, 2 and 3 determined and compared with control plants. The result of present study demonstrated that there was a significant accumulation of heavy metals in leaves of plants growing in Pithampur Industrial area sector-1, 2 and 3 when compared with control. Highest accumulation of heavy metal was observed in A.indica (59.11µg/gm of dry weight of leaves) and the lowest accumulation was observed in C. gigantean (14.68 µg/gm dry weight of leaves). There was negative correlation between heavy metal accumulation and total photosynthetic pigment. Significant negative correlation was observed in sector -2 i.e. r = -0.61 i.e. accumulation was adversely affecting the total photosynthetic pigments.
