Can you test fragrance odors

[Guest guest]

I was wondering if there is a way to test what comes out of the

exhaust system. I have fragrance coming into apartment. Fragrance

even comes out of the intake and that is supposed to draw air in.

Also

I wondered if you could test the stuff that comes out of the dryer

exhaust that are right by the windows. We know it is dangerous but

is

there a way to see what chemicals are coming out of the exhaust. I

always think if a baby was in a room sleeping in a crib by the window

and the door was shut and all the chemicals that come in the window

when people are doing their wash.
