Plant Exposure to Engineered Nanoparticles: Uptake, Transformation, Molecular and Physiological Responses discusses the long-term exposure of plants, including agronomic crops, to nanomaterials in terrestrial environments. Chapters discuss changes in metabolite profiles in plants exposed to engineered nanomaterials, as well as modifications in elemental content of edible portions of plants. Biochemical pathways, root profiles, generational exposure, and biomass productivity are also analyzed in detail.

Subsequent chapters cover risks to trophic transfer, as well as human health and ecological functions, before concluding with future approaches to plant-nanomaterial research. The book covers important aspects of the interactions between plant and nanomaterials and will be a valuable resource to scientists and researchers in plant physiology, nanotechnology, agronomy and environmental science.
