The level of `393060 s! n2 by sonicatior in 'carpet is quite high. I: have: attached ;itudy that shows thai even in buildings known to re asbestos contairshg materials is around 1.000 stru s per square oentirnieter, according to an :abthoritative'.book, excerpts attached.

Before*:the .W TO-cofla :, jn 1980, suffers durst outdoors in New: YorkCI#y-was a average of 510Q s/dm2 (from.a study by;Ewing.jj iresented at the Jot r son Conference in the.sumrer'of 2002)f.

Thus, the levels you foil dare definitely over background and deserveatt+htion Jl Jobody can tell you' 0th any certainty exactly. how hoi rdous these Ievel .are, but EPA statutes arid poll lE s °say that any expoure to asbestos Is hazardous, and atter Dtl'ng to get levels to'•background is desirable..
