What is the impact of dilution ventilation and particle filtration on concentrations of liquid aerosol tagged with synthetic DNA?
To evaluate the impact of dilution ventilation and particle filtration on concentrations of liquid aerosols tagged with patented aerosol tracers (veriDART® by SafeTraces) compared to conventional tools like tracer gas and particle size distribution monitoring, authors from RHP Risk Management, SafeTraces, along with Carlos Carpio (Texas Tech University) and Nicholas Clements (University of Colorado Boulder) conducted testing under a range of dilution ventilation rates, recirculation rates, and filtration types with patented DNA-tagged #aerosol tracers and tracer gases emitted simultaneously. Tracer decay rates were compared across experimental conditions to observe the impact of aerosol mitigation efforts on tracer decay rates, as well as highlight differences between liquid aerosol and gaseous tracer decay rates.
