Real ‐world volatile organic compound emission rates from seated adults and children for use in indoor air studies
Abstract
Human beings emit many volatile organic compounds (VOCs) of both endogenous (internally produced) and exogenous (external source) origin. Here we present real‐world emission rates of volatile organic compounds from cinema audiences (50‐230 people) as a function of time in multiple screenings of three films. The cinema location and film selection allowed high‐frequency measurement of human‐emitted VOCs within a room flushed at a known rate so that emissions rates could be calculated for both adults and children. Gas‐phase emission rates are analyzed as a function of time of day, variability during the fil...

The ventilation problem in schools: literature review
Abstract
Based on a review of literature published in refereed archival journals, ventilation rates in classrooms often fall far short of the minimum ventilation rates specified in standards. There is compelling evidence, from both cross‐sectional and intervention studies, of an association of increased student performance with increased ventilation rates. There is evidence that reduced respiratory health effects and reduced student absence are associated with increased ventilation rates. Increasing ventilation rates in schools imposes energy costs and can increase heating, ventilating, and air‐conditioning system capi...

Emission strength of airborne pathogens during toilet flushing
This study investigated the emission strength of three types of airborne bacteria, namely, Staphylococcus epidermidis, Escherichia coli and Pseudomonas alcaligenes, during toilet flushing in a custom‐built toilet under a controlled environment. Flushing was activated by a flushometer operated at two pressure levels, 400 kPa (high pressure [HP]) and 200 kPa (low pressure [LP]), and by a water cistern tank placed 95 cm (high tank [HT]) and 46 cm (low tank [LT]) above the toilet seat. The pathogens emitted by the first flush were calculated, with the correlations between airborne pathogen emissions and droplet concentration...

Optimization of PMA ‐qPCR for Staphylococcus aureus and determination of viable bacteria in indoor air
This study evaluated quantitative PCR (qPCR) with propidium monoazide (PMA) to quantify S. aureus. The results showed comparable S. aureus counts between exclusively live cells and mixtures of live/dead cells by qPCR with 1.5 or 2.3 μg/mL PMA (P>0.05), illustrating the ability of PMA‐qPCR to detect DNA exclusively from viable cells. Moreover, qPCR with 1.5 or 2.3 μg/mL PMA performed optimally with linearity over 103‐108 CFU/mL (R2≥0.9), whereas qPCR with 10, 23 or 46 μg/mL PMA significantly underestimated viable counts. S. aureus and total viable bacteria were further determined with PMA‐qPCR (1.5 μg/mL) fro...

Size and mineral composition of airborne particles generated by an ultrasonic humidifier
This study describes the size distribution and concentration of particles expelled by a portable, 3 L ultrasonic humidifier. The ultrasonic humidifier was filled with waters of varying mineral content and hardness. Aerosol size distributions were measured during 8 h of humidifier operation in a typical bedroom. Humidifiers produced approximately 1.22 ×1010 to 2.50 ×1010 airborne particles per milliliter of water consumed, resulting in airborne particle concentrations of 3.01 ‐ 5.91×104 #/cm3, with modes ranging between 109 and 322 nm in diameter. The emission rate of particles varied by water type from 1.02 ×109 to 2...
