CO2 makes up 390 ppm (0.039%)* of the atmosphere, how can such a small amount be important? Saying that CO2 is "only a trace gas" is like saying that arsenic is "only" a trace water contaminant. Small amounts of very active substances can cause large effects. Some Examples of Important Small Amounts :He wasn't driving drunk, he just had a trace of blood alcohol; 800 ppm (0.08%) is the limit in all 50 US states, and limits are lower in most other countries). Don't worry about your iron deficiency, iron is only 4.4 ppm of your body's atoms ( Sterner and Eiser, 2002 ). Ireland isn't important; it's only 660 ppm (0.066%) of the world population. That ibuprofen pill can't do you any good; it's only 3 ppm of your body weight (200 mg in 60 kg person). The Earth is insignificant , it's only 3 ppm of the mass of the solar system. Your children can drink that water, it only contains a trace of arsenic (0.01 ppm is the WHO and US EPA limit). Ozone is only a trace gas: 0.1 ppm is the exposure limit established by the US National Institute for Occupational Safety and Health. The World Health Organization (WHO) recommends an ozone limit of 0.051 ppm. A few parts per million of ink can turn a bucket of water blue. The color is caused by the absorption of the yellow/red colors from sunlight, leaving the blue. Twice as much ink causes a much stronger color, even though the total amount is still only a trace relative to water. skepticalscience.com New Botulinum Toxin Deemed Deadliest Substance Ever: Sniffing 13-Billionths Of A Gram Can Killmedicaldaily.com
