(I know little science so please help me if I'm in the wrong place or if my question needs editing. I could use help with tagging, for example.)
If I can smell something then does that mean there are particles or chemicals in the air?
My question is motivated by some new window blinds that have been installed in my home. The blinds have a smell, which is most noticeable when the sun is shining on them. I am trying to work out if the blinds are emitting some chemical into the air. This question is my first step.
[This question is not the same as "How does the smell of a compound come about, and is it possible to define a smell?". This is clear from the title.]
