...there's a higher ick factor to dust than you might think. And there's a science to how it gets around - a science that David Layton and Paloma Beamer, professors of environmental policy at the University of Arizona, are exploring. (See the top 10 scientific discoveries...
...Layton and Beamer, whose latest study has been accepted for fall publication in the journal Environmental Science & Technology, knew a lot about their subject even before they set to work. Historically, everyone from chemists to homemakers has tried to figure out just what dust is made of, and the Arizona researchers drew their preliminary data mostly from two studies of household dust conducted in the Netherlands and the U.S. The American survey in particular was a big one, covering six Midwestern states. Layton and Beamer also included a localized study in Sacramento, Calif., that focused particularly on lead contamination. What...
...dust's ingredient label is not the whole story, since all of those flecks and bits behave differently and present different levels of health risk. To investigate those factors more closely, Layton and Beamer developed a computer algorithm that looked at the size, source and toxicity of dust particles as well as how easily they enter the house, if they ever exit and, if so, by what route. That information, by extension, can provide at least a rough sense of the dust load in your own home. (See TIME's special report "How to Live 100 Years...
...routinely transfer things from their hands to their mouths. The same is true for lead, which comes less from wall paint - the source most people would expect - than from auto exhaust, smelting and soil deposits. "Lead loading on floors is a key determinant of blood-lead levels in children," Layton and Beamer wrote in their paper. (See "The Year in Health 2009: From...
