A characteristic information extraction method of a small-molecule volatile substance, including: dividing a surface-enhanced Raman scattering (SERS) spectrum of the small-molecule volatile substance to obtain n wavelength subintervals, where n is a positive integer; sampling the n wavelength subintervals through weighted bootstrap sampling (WBS) to obtain W wavelength subintervals, where W is a positive integer less than n; and screening the W wavelength subintervals to obtain desired wavelength subintervals. This application also provides a rapid detection method and a portable detection system of a small-molecule volatile substance.

A method for fast extracting an organic pollutant in a complex system is disclosed, which includes following steps. A surface-enhanced Raman scattering (SERS) spectrum of an organic pollutant is divided to obtain P wavelength sub-intervals with overlapping regions. The P wavelength sub-intervals are screened to obtain &#x3c9; wavelength sub-intervals. The &#x3c9; wavelength sub-intervals are screened to obtain a required wavelength sub-interval. The required wavelength sub-interval is screened to obtain a required wavelength subset. A method and a system for fast detecting an organic pollutant in a complex system are also disclosed.
