Officials from the UAW headquarters, in Detroit, have declined to comment on the festering disputes. But critics of the union's leadership acknowledge that there isn't much the union can do to win back lost wages and benefits or even hold the line in the face of new demands for concessions, given the steady decline of organized labor across the automotive sector...
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...
...cleaning and smoking habits. But nearly everywhere, dust consists of some combination of shed bits of human skin, animal fur, decomposing insects, food debris, lint and organic fibers from clothes, bedding and other fabrics, tracked-in soil, soot, particulate matter from smoking and cooking, and, disturbingly, lead, arsenic and even...
...organic materials such as pollen (though they can trigger allergies), but lead, 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...
Problem solved, right? The trouble is that as controversial as cap-and-trade legislation has become, EPA regulation is an even bigger political minefield. Republicans are universally against it, claiming that clumsy top-down CO2 regulation will kill American jobs by strangling power plants and other industry. Senator Lisa Murkowski, a Republican from Alaska, introduced a bill late last year that would explicitly prevent the EPA from regulating carbon, and she already has 40 co-sponsors. Many Democrats also have their doubts - eight Democratic Senators from coal-heavy states sent a letter on Sunday, Feb. 21, to EPA administrator Lisa...
