‘Nanotechnology’ refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. The scope of this study is to investigate the effect of lead nano particle which is settle in the uppermost layer of the leaf,soils and plants collected from industrial area in western ghats region.in this connection the environmental pollution of the bioindicator is soil,plants and the grasshopper. Nanotechnology is being studied by governments, and they promise discoveries that will revolutionize information technology as we know it. They plan to make it smaller but faster, less expensive but higher quality, and just all around excellent to use attempting to enhance what humans use during their everyday life The feed pollutionis occurred by Na,Mg,AI,Si,CI,K,Ca,Mn,Fe,Cr,Co,Ni,Cu,Zn,As,Se,Pb and Cd. The grasshopper is an insect of the suborder Caelifera in the order Orthoptera. To distinguish it from bush crickets or katydids, it is sometimes referred to as short-homed grasshoppers. Calotrophis plant is feeded by the painted grass hopper due to the feed contamination species will produce the abnormal growth and its been completely extinct.due to the presence of exceess lead materials due to industrial pollution. The pigment which is responsible for the growth of the wings will be present in the plant and due to the pollution the pigment is completely been destroyed Flavonoids in plants isorhamnetin-3-0rutinoside, isorhamnetin-3-0-glucopyranoside and taraxasteryl acetate, flavonol trisaccharide was isolated from the aerial parts of Calotropis gigantea, and its structure was established as isorhamnetin-3-0-[2-0-beta-Dgalactopyranosyl-6-0-alpha-L-rhamnopy ranosyl]-beta-D-glucopyranoside by R. Padmadhas and R. Ragunathan a combination of fast atom bombardment mass spectroscopy, It is used for the formation ofthe wings
