In a pot experiment, saplings of Ocimum basilicum, O. sanctum, O. americanum and Mentha spicata were planted in metal amended soils. The plants of O. sanctum and O. americanum were unable to survive after 120 days. The aerial parts of O. basilicum were harvested after 120 and 210 days while Mentha after 90, 150 and 210 days. They were subjected to steam distillation and extracted with,z-hexane and dichloromethane. The oil composition was analyzed by GC and GC/MS. Metal (copper and lead) content was determined by atomic absorption spectroscopy. There was significant quantitative variation in the composition of essential oil for O. basilicum growing on copper amended soil as compared to lead amended soils while no change was observed for M. spicata. Both., O. basilicum and M. spicata showed vigorous growth with no symptoms of morpho-phytotoxicity, despite the accumulation of lead and copper. O. basilicum showed better metal accumulation than M. spicata.
