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

A method comprising:

• during a test period:
• during a dispense period, triggering release of a first tracer test load into ambient air in an environment, according to a first set of release parameters, by a dispenser arranged within the environment, the first tracer test load comprising a first concentration of tracers of a first type;
• and
• triggering a first air sampler, in a set of air samplers, located in the environment, to record a timeseries of aerosol data via a set of sensors integrated into the air sampler;
• and
• in response to expiration of the test period:
• deriving a tracer signal, in a set of tracer signals, representing changes in amounts of tracers in air detected at the air sampler during the test period based on the timeseries of aerosol data recorded at the air sampler and the first set of release parameters;
• based on characteristics of the set of tracer signals, characterizing a set of aerosol flow metrics, including air-change rate, representing behavior of aerosols in the environment during the test period;
• characterizing infection risk, associated with a set of pathogens, for the environment during the test period based on the set of aerosol flow metrics and a set of zone characteristics defined for the environment;
• and
• in response to infection risk associated with a first pathogen, in the set of pathogens, exceeding a threshold infection risk:
• generating a notification indicating risk associated with the first pathogen in the environment;
• and
• transmitting the notification to a user affiliated with the environment.
