Toxicology - from coal mines to nanotechnology

The study of adverse health effects of nanosized particles is nothing new. Particle toxicology is a mature science, dealing with the exposure to airborne nanosized (or ultrafine) particles that either occur naturally or have increasingly been introduced through human activities or industrial products such as materials that include asbestos fibers and coal dust. Research on ultrafine particles has laid the foundation for the emerging field of nanotoxicology, with the goal of studying the biokinetics of engineered nanomaterials and their potential for causing adverse effects ("Nanotoxicology: An Emerging Discipline Evolving from Studies of Ultrafine Particles"). Most reports find that ultrafine particles are more toxic than equivalent larger-sized particles of a given material at similar doses per gram of body weight.
