Plants can’t move away and are therefore continuously confronted with un-favourable environmental conditions (i.e. different kind of biotic & abiotic stress). Effect or impact of heavy metals (i.e. heavy metal stress) on agricultural crops is a growing concern of recent times. Out of different morphometric & physiological effects, chlorosis (lack of synthesis or accumulation of adequate amount of Chlorophyll) is one of the visible symptom of heavy metal stress. IR-36 a very popular and high yielding rice variety to Indian farmers, artificially treated with successive grades of Cd & Pb salt. Then chlorophyll was extract from the leaves of this salt treated or stressed plants as well as controlled. After that characterised by UV-visible spectroscopy and amount of total chlorophyll and chlorophyll-a & chlorophyll-b using Arnon, 1949 method. Indicating sharp decrease or fall out of chlorophyll content, according to increase of heavy metal concentration. Effect of Cadmium (Cd) is more devastating than Lead (Pb)
