The dust that accumulates in the corners of your house does more than just cause allergies and aggravation
it’s also teeming with clues about where you live and who you live with.
That’s the finding of a study in the Proceedings ofthe Royal Society B.
Researchers had volunteers at nearly 1,200 homes across the U.S. collect indoor and outdoor dust samples.
The average home’s dust contains about 5,000 types of bacteria and 2,000 types of fungi.
The fungi gave away a lot about a home’s location.
Different regions have different fungal populations, and thus so do houses within those regions.
For example, dwellings around the Great Lakes had very different fungi than did homes inArizona
because most household fungi originate outside and come in either on people’s clothes orthrough windows and doors.
As for the bacteria, those were strong indicators of the identity of the home’s residents.
Much of the bacteria was shed by the human body and was a pretty good indicator of ahome’s gender ratio.
The single–celled organisms also showed whether a pet shared the home,cats and dogs maketheir own The research could inform forensic investigations and allergy studies.
In the meantime, what can we take from these findings?
Well, you can clean up dust but you can’t change its composition.
That is, unless you move.
Or make some changes in the pets and people you live with.
aggravation： [,ægrə’veɪʃn] n. 加剧
bacteria：[bækˈtɪəriə] n.细菌
fungi：[ˈfʌŋgi: ] n. 真菌 (fungus的复数)
