Nanomaterials

Nanomaterials: Toxicity, Health and Environment offers a critical and comprehensive examination of the interactions between engineered nanomaterials and biological as well as ecological systems. This book is designed for students, researchers, and professionals in nanotechnology, toxicology, environmental science, and public health, providing a balanced perspective on both the promise and the risks associated with nanomaterial applications.

The book begins with an overview of nanomaterials-defining their unique physicochemical properties, classification, and widespread uses in sectors such as medicine, electronics, agriculture, and cosmetics. It then delves into how these materials interact with living organisms at the cellular and molecular levels, raising important questions about bioaccumulation, oxidative stress, and cytotoxicity.

Detailed chapters explore the mechanisms of nanotoxicity, covering in vitro and in vivo testing models, dose-response relationships, and biomarkers of exposure. The book also discusses occupational and environmental exposure pathways, including inhalation, dermal contact, and water and soil contamination, offering insights into both acute and chronic effects.

Attention is given to regulatory frameworks, risk assessment models, and international guidelines for the safe handling and disposal of nanomaterials. The text also highlights sustainable design approaches and green nanotechnology practices that aim to minimize environmental footprint while maintaining innovation.
