1. An inspection method for inspecting sources of emission of at least one target chemical at a site, the inspection method comprising:
providing a predominate air quality monitor comprising:
a first sensor responsive to a first target chemical from the at least one target chemical; and
a first location at which the predominate air quality monitor is located;
measuring a first concentration of the first target chemical by the predominate air quality monitor;
generating a first signal representative of the first concentration of the first target chemical;
providing a secondary air quality monitor comprising:
a second sensor responsive to a second target chemical from the at least one target chemical; and
a second location at which the secondary air quality monitor is located;
measuring a second concentration of the second target chemical at the secondary air quality monitor;
generating a second signal representative of the second concentration of the second target chemical;
identifying sources of emission of the first target chemical and the second target chemical with an analysis of the first signal and the second signal; and
inspecting with at least one sensing modalities, the sources of emission of the first target chemical and the second target chemical.
