Nanoparticles Toxicity and their Effects on Health: An Ethical Study

Abstract

Nanotechnology is a rapidly growing science of producing and utilizing nanosized particles that measure in nanometers. While nanotechnology and the production of nanoparticles are growing exponentially, research into the toxicological impact and possible hazard of nanoparticles to human health and the environment is still in its infancy. Nanoparticles, even when made of inert elements like gold, become highly active at nanometer dimensions. Therefore, understanding the risks and identifying the magnitude of potential harm are two important considerations for an informed use of nanoparticles. This review aims to give a comprehensive summary of what is known today about possible impacts of nanoparticle toxicology to public health. On the other hand, studies in the development of nanoparticles' toxicity raise various ethical questions concerning safety, possible risks and side effects of nanoparticles. There are also speculations as to the moral problems or dangers that may arise in connection with further advances in this type of nanomaterials. Therefore, the second part of this paper highlights the need for caution during the use and ethical aspects of such manufactured nanomaterials to prevent unintended environmental impacts.
