Its hard to get too worked up about dust. Yes, its a nuisance, but its hardly one that causes us much anxiety and our language itself suggests as much. We call those clumps of the stuff under the bed dust bunnies after all, not, say, dust vermin.
to get worked up 为某件事生气;不开心
clumps of 一团一团的
dust bunny 积尘;灰兔子(关于灰尘的比较萌的说法)
But theres a higher ick factor to dust than you might think. And theres 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.
get around 传播;散播
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 all those surveys showed was decidedly unappetizing.
