Introduction
Agriculture is witnessing a dramatic transition as nanotechnology is integrated into crop protection techniques. Conventional pesticides have long been necessary for pest control and for worldwide food security, yet their widespread use has raised serious concerns about environmental contamination, pest resistance, and adverse effects on human health. In response to these issues, nanopesticides have emerged as a potential next-generation alternative to enhance the efficacy, stability, and targeted delivery of active pesticide ingredients. Nanopesticides use nanoscale materials such as nanoemulsions, nanocapsules, polymeric nanocarriers, and metal or metal oxide nanoparticles to provide controlled release, increased bioavailability, and lower application doses, potentially reducing environmental burdens while increasing agricultural productivity.
Despite these technological advantages, the use of nanopesticides in agricultural systems raises serious concerns regarding their safety and long-term consequences. Nanomaterials, due to their tiny size and unique physicochemical properties—including increased surface area, improved reactivity, and the ability to penetrate biological membranes—may interact with living systems in ways that differ dramatically from those of traditional pesticide formulations. These characteristics may influence their environmental destiny, bioaccumulation potential, and toxicity profiles, posing significant problems to toxicological evaluation and risk assessment.
Understanding the effects of nanopesticides on human health has thus become a top research goal. Exposure can occur through various channels, including occupational contact during industrial and agricultural applications, inhalation of aerosolized particles, cutaneous absorption, and ingestion of residues in food and water. New scientific evidence shows that certain nanomaterials can induce oxidative stress, inflammation, genotoxicity, and changes in cellular and physiological systems. However, the present understanding is fragmented, and more interdisciplinary research is still required to fully understand the mechanisms, hazards, and safe applications of nano-enabled agrochemicals.
This edited collection, "Nanopesticides and Their Impact on Human Health," provides a comprehensive platform for researchers, scientists, and policymakers to investigate the intricate relationships among nanotechnology, agriculture, environmental safety, and human health. The book will include contributions from experts in a variety of disciplines, including nanotechnology, toxicology, environmental chemistry, agricultural science, biotechnology, and public health, to present the most recent advances in nanopesticide development, nanotoxicity mechanisms, exposure pathways, ecological interactions, and regulatory frameworks.
This book aims to close the gap between innovation and safety in nano-enabled agriculture by combining scientific insights and practical viewpoints. It will highlight emerging research trends, identify knowledge gaps, and recommend ways to design, regulate, and apply nanopesticides responsibly. Finally, this publication seeks to promote the development of safer, more sustainable, and scientifically informed agricultural technologies that protect crop yield and human health in an era of rapidly increasing nanoscience.
