Pterocarpus santalinus Linn.f., commonly named as "Red sanders" and Rakta Chandana is one of the endemic and endangered plant species of Indian environment. This important bioresource is utilized in diverse way through out the world. This tree is precious due to its ethno medicinal utility. But industrialization, rapid urbanization, slow growth rate of the plant, unique floristic features, special geobotany and high demand of pigment production from the tree have created threats to the existence of this plant. In view of these as well as due to restricted and limited distribution of this plant species, it requires immediate attention for better conservation programme.

Indigenous fish, Labeo bata were provided with acute as well as chronic exposure of copper nanoparticle of two different size forms i.e., 25 nm and 60-80 nm. Reduction in specific growth rate (SGR), alterations in hematological and biochemical assay of fish and changed morphology were prominent after chronic exposure of variable size and concentration of copper nanoparticles. Modification in the carbohydrate and protein profile induced by copper nanoparticles might be considered as suitable biomarkers of fish health. Size reduction of metallic nanoparticle was found to be very crucial factor for imparting toxicity to aquatic organisms rather than their concentration. Structural deformity in the caudal region was manifested due to increased bioavailability of small sized (25 nm) nanoparticles through intramuscular application.Keywords
