...arsenic and DDT can be a more serious matter. About one-third of the arsenic in the atmosphere comes from natural sources - volcanoes principally. The rest comes from mining, smelting, burning fossil fuels and other industrial processes. Even in relatively low concentrations, arsenic is not without risk, especially to small children who play on the floor and 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...
...eating, the more food debris you'll drop on the floor - which also attracts more insects that will die, decompose and add their own special zest to your dust. Cooking smoke and tobacco smoke, which are the most obvious contributors when they're being produced, actually make only a small contribution to what winds up on floors and surfaces. The tiny size of the particles makes them likelier to rise and adhere to other surfaces or simply remain in the air than to settle. (See the top 10 medical breakthroughs...

No one expects Bashir to quietly accept an unfavorable result, for instance, something that is a small but rising possibility with the entrance of some heavyweight rivals in the presidential race. There are concerns about how confusing the vote will be - in the south, voters will be asked to cast 12 separate votes for various national and regional institutions - and the competence of the election officials. And a poll alone can hardly turn the south into a fully functioning nation. After decades of war and chronic underdevelopment, David Gressly, the U.N.'s regional...
