Electronic Cigarettes Contain Toxic Metal Nanoparticles
After testing the aerosol from a leading manufacturer of electronic cigarettes, it was found to contain metals including tin, copper, nickel and silver, silicate beads and nanoparticles. In some cases, such as in the case of tin particles, the amounts were greater than you might be exposed to from smoking a conventional cigarette. The researchers concluded:3
“Cartomizer aerosol from a leading manufacturer of EC [electronic cigarette] contained metals, silicate beads, and nanoparticles. Poor solder joints appear to have contributed to the presence of tin in the aerosol. In cytotoxicity tests, cartomizer fluid containing tin particles inhibited attachment and survival of hPF [human pulmonary fibroblasts].
Other metals likely came from the wires (copper, nickel, silver) and other metal components used in the cartomizers, while silicate particles appeared to come from the fiberglass wicks.
While the outer fibers filtered out many of the tin particles, significant amounts of tin, other metals, and silicate beads escaped into the aerosol and would result in human exposure, in some cases probably greater than a conventional cigarette user would experience.” [emphasis added]
The effects of toxic metal exposures can range from subtle symptoms to serious diseases. Since metals build up in your body over time, symptoms are often attributed to other causes and people often don't realize that they have been affected by metals until it's too late. Further, once metals build up in your body they can cause irreversible damage.
Why Breathing in Metal Nanoparticles May be Dangerous
Adding to the potential risks are nanoparticles, which, due to their ultramicroscopic size, can easily enter your bloodstream, blood vessels and other body tissues, causing unknown consequences. As written by Sayer Ji, founder of GreenMedInfo.com:4
“One of the unintended, adverse consequences of nanotechnology in general is that by making a substance substantially smaller in size than would occur naturally, or though pre-nanotech production processes, the substance may exhibit significantly higher toxicity when in nanoparticle form.
Contrary to older toxicological risk models, less is more: by reducing a particle's size the technology has now made that substance capable of evading the body's natural defenses more easily, i.e. passing through pores in the skin or mucous membranes, evading immune and detoxification mechanisms that evolved millions of years before the nanotech era.
For example, when nickel particles are reduced in size to the nanometer range (one billionth of a meter wide) they may actually become more toxic to the endocrine system as now they are capable of direct molecular interaction with estrogen receptors in the body, disrupting their normal structure and function. Moreover, breathing these particles into the lungs, along with other metals, ethylene glycol and nicotine produces a chemical concoction exhibiting synergistic toxicity, i.e. the toxicity of the whole is higher than the sum of their parts.”
