1. A method comprising:
during a calibration period for an environment:
triggering collection of an initial aerosol sample, over an initial sampling period, by an air sampler located in the environment;
during the initial sampling period, triggering dispensation of a first tracer test load by a dispenser located in the environment, the first tracer test load comprising a set of tracer particles in solution;
accessing a first detected tracer level of a first tracer, in the set of tracer particles, detected in the initial aerosol sample;
accessing a first true tracer level of the first tracer present in the first tracer test load; and
deriving a first calibration factor, in a set of calibration factors, for the first tracer in the environment based on a difference between the first detected tracer level and the first true tracer level; and
during a live period succeeding the calibration period:
triggering collection of a first aerosol sample, over a first sampling period, by the air sampler;
accessing a first detected pathogen level of a first pathogen, in a set of pathogens, detected in the first aerosol sample; and
predicting a first pathogen level of the first pathogen in the first aerosol sample based on the first detected pathogen level and the first calibration factor.
