N,N-diethyl toluamide (DEET): An insect repellant used widely since the 1950s. Although it is effective in repelling insects, it can be harmful if ingested, causing some neurological problems, including lethargy, confusion, disorientation, and mood swings. It is an eye irritant and may cause blisters, rashes, or other skin irritations. It has also been found in low quantities in tap water, evidence of pollution.
Nanoparticles: Mineral particles that have been fragmented to sizes below 100 nanometers; they are often used in sunscreens and mineral makeup products because they are less visible when applied to the skin.
Natural Products Association Certified: This certification is applied to products with 95 percent of the ingredients derived from natural sources (for instance, plants, milk, honey, beeswax, minerals); synthetic ingredients are allowed only when no viable natural alternative exists. Regardless of source, the ingredients must not pose any potential human health problem, and companies can't process natural ingredients in any way that could significantly alter their purity.
Neurotoxins: Toxins which attack the nervous system. They are especially hazardous to fetuses and children. High exposures can result in brain damage. The most commonly occurring and dangerous neurotoxins are lead, mercury, OPs and PCBs.
Nitrogen Dioxide (NO2): Formed from nitrogen and oxide, it is a highly reactive gas. It is made when fuel is burned at high temperatures. The primary manmade sources for nitrogen dioxide are motor vehicles and electric utilities. It is a greenhouse gas which, along with other greenhouse gases, is causing a gradual rise in the earth’s temperature.
