Engineered nanomaterials today are already being used in diverse commercial products in the fields of energy, sensing, food technology, electronics, pharmaceuticals, cosmetics, and material applications and have an estimated global market value of €20 billion. This has given rise to concerns about the undesirable effects of this technology on the environment. This review presents an overview of published studies about likely impact of nanoparticles in the ecosystem, their ecotoxicology, threat to human health and the environment and lack of sufficient data in the Indian context.
