Health Effects and Workplace Assessments and Controls

Employees who use nanomaterials in research or production processes may be exposed to nanoparticles through inhalation, dermal contact, or ingestion, depending upon how employees use and handle them. Although the potential health effects of such exposure are not fully understood at this time, scientific studies indicate that at least some of these materials are biologically active, may readily penetrate intact human skin, and have produced toxicologic reactions in the lungs of exposed experimental animals.

Current research indicates that the toxicity of engineered nanoparticles will depend on the physical and chemical properties of the particle. Engineered nanomaterials may have unique chemical and physical properties that differ substantially from those of the same material in bulk or macro-scale form. Properties that may be important in understanding the toxic effects of nanomaterials include particle size and size distribution, agglomeration state, shape, crystal structure, chemical composition, surface area, surface chemistry, surface charge, and porosity.

The resources below contain information on the potential health effects of exposure to nanomaterials and workplace exposure control methods. As part of a government-wide coordination effort, OSHA is working with other federal agencies to address issues related to the impact of nanomaterials on human health and the environment.

During the Middle Ages, philosophers attempted to transmute base materials into gold in a process called alchemy. While their efforts proved fruitless, the pseudoscience alchemy paved the way to the real science of chemistry. Through chemistry, we learned more about the world around us, including the fact that all matter is composed of atoms. The types of atoms and the way those atoms join together determines a substance's properties.

Nanotechnology is a multidisciplinary science that looks at how we can manipulate matter at the molecular and atomic level. To do this, we must work on the nanoscale -- a scale so small that we can't see it with a light microscope. In fact, one nanometer is just one-billionth of a meter in size. Atoms are smaller still. It's difficult to quantify an atom's size -- they don't tend to hold a particular shape. But in general, a typical atom is about one-tenth of a nanometer in diameter.

But the nanoscale is where it's at. That's because it's the scale of molecules. By manipulating molecules, we can make all sorts of interesting materials. But like the alchemists of old, we wouldn't make much headway in creating gold. That's because gold is a basic element -- you can't break it down into a simpler form.

We could make other interesting substances, though. By manipulating molecules to form in particular shapes, we can build materials with amazing properties. One example is a carbon nanotube. To create a carbon nanotube, you start with a sheet of graphite molecules, which you roll up into a tube. The orientation of the molecules determines the nanotube's properties. For example, you could end up with a conductor or a semiconductor. Rolled the right way, the carbon nanotube will be hundreds of times stronger than steel but only one-sixth the weight [source: NASA].

That's just one aspect of nanotechnology. Another is that materials aren't the same at the nanoscale as they are at larger scales. Researchers with the United States Department of Energy discovered in 2005 that gold shines differently at the nanoscale than it does in bulk. They also noticed that materials possess different properties of magnetism and temperature at the nanoscale [source: U.S. Department of Energy].

Because the science deals with the basic building blocks of matter, there are countless applications. Some seem almost mundane -- nanoparticles of zinc oxide in sunblock allow you to spread a transparent lotion on your skin and remain protected. Others sound like science fiction -- doctors are attempting to use the protein casings from viruses to deliver minute amounts of drugs to treat cancer. As we learn more about how molecules work and how to manipulate them, we'll change the world. The biggest revelations will come from the smallest of sources.
