Right but chemists can detect things at vanishingly small concentrations so "detected" often provides almost no information without further context.
If you look hard enough you're very often going to find the molecule you're looking for.
Was it detected at 0.1%, 100% or 10000% of an arbitrary EPA limit? This provides at least some quantitative indication of what's going on.
