System and method for characterizing, monitoring, and detecting bioaerosol presence and movement in an indoor environment

A method comprising:

• during a calibration period for an environment:
• triggering collection of a first bioaerosol sample by an air sampler located in the environment over a first sampling period of a fixed duration;
• and
• during the first sampling period, triggering dispensation of a first tracer test load by a dispenser in the environment, the first tracer test load comprising:
• a first amount of an unmodified barcode;
• and
• a second amount of a modified barcode corresponding to the unmodified barcode and linked to a first intervention type;
• accessing a first detected amount of the unmodified barcode present in the first bioaerosol sample collected by the air sampler during the first sampling period;
• deriving a calibration factor, in a set of calibration factors, based on the first amount and the first detected amount of the unmodified barcode;
• accessing a second detected amount of the modified barcode detected in the first bioaerosol sample;
• predicting an adjusted detected amount of the modified barcode present in the environment, during the first sampling period, based on the second detected amount and the calibration factor;
• and
• characterizing a detected dosage of the first intervention type in the environment during the first sampling period based on a difference between the adjusted detected amount and the second amount of the modified barcode dispensed in the first tracer test load.
