Abstract: One variation of a method includes, during a calibration period: triggering collection of an initial bioaerosol sample by an air sampler located in an environment; and triggering dispensation of a tracer test load by a dispenser located in the environment; accessing a detected barcode level of a barcode detected in the initial bioaerosol sample; accessing a true barcode level of the barcode contained in the tracer test load; and deriving a calibration factor for the environment based on a difference between the detected barcode level and the true barcode level. The method further includes, during a live period succeeding the calibration period: triggering collection of a first bioaerosol sample by the air sampler; accessing a detected pathogen level of a pathogen detected in the first bioaerosol sample; and interpreting a predicted pathogen level of the pathogen in the environment based on the detected pathogen level and the calibration factor.

Abstract: The present invention refers to a device comprising polytetrafluorethylene (PTFE) filters and the use of the same for collecting, detecting and identifying organisms present in air ecosystems. The invention also provides a method suitable for the capture, detection and identification of whole airborne biological particles, including viruses and other important air pathogens, which involves the use of the device. This method allows toperform organism, preferably viral, metagenomics to sequence all DNA and RNA organisms captured in the filters. This methodology may be used to detect, for instance, SARS-CoV2 particles in air samples.

Abstract: An apparatus includes (i) a test chamber having an inlet and an outlet; (ii) an introduction system configured to introduce a test pollutant into the test chamber such that the test pollutant is entrained in air flowing from the inlet to the outlet; (iii) a support configured to retain the test article, wherein the support defines a passageway downstream of a location of the test article such that air flowing from the inlet to the outlet passes through the filter medium prior to entering the passageway; (iv) an air flow apparatus configured to draw air from within the test chamber through the passageway and the outlet; and (v) a respiratory conditions simulation system configured to simulate an aspect of respiration, an external environment simulation system configured to simulate an aspect of an external environment, or both the respiratory conditions simulation system and the external environment simulation system.

Abstract: A portable sampler, the sampler including a sampler assembly having a housing that includes a receiver defined therein for interchangeably receiving a number of removable inlet assemblies, the removable inlet assemblies including a respirable inlet assembly and a thoracic inlet assembly. The respirable inlet assembly includes a hybrid cyclone assembly, the hybrid cyclone assembly including an impaction stage and a cyclone in series. The thoracic inlet assembly includes an inlet slot configured to function as a size-selective inlet. Another thoracic inlet assembly includes a housing having a number of openings configured to receive a sample airflow; an inlet insert through which an inlet aperture is defined; a prequalification chamber defined between a lower surface of the housing and an upper surface of the inlet insert; and a protrusion extending downward from the lower surface of the housing into the inlet aperture of the inlet insert to from an inlet slot.
