“… Tyagi and Malik (2012) and Tyagi et al (2012) proposed the use of EOs in the vapor phase, by combining bactericidal volatiles and ionizing sources. Since active compounds of EOs are highly volatile, the presence in gaseous form facilitates the solubilization of lipophilic monoterpenes in cell membranes.…”

Essential oils (EOs) are liquid preparations, produced from plant materials. Although EOs showed a promising bioactivity in vitro, they could interact in foods with some components (fats, proteins, carbohydrates) and pH, thus many authors have reported that a significant effect of EOs toward spoiling and pathogenic microorganisms could be achieved in vivo by using higher amounts of oils. Different methods can be used to assess the bioactivity of EOs (disk diffusion and agar or broth dilution methods); however, there is not a standardized test and researchers propose and use different protocols (evaluating the Minimal Inhibitory Concentration, studying the survival curves, analysis through the scanning electron microscopy, etc.). Thereafter, the scope of this review is a focus on interactions of EOs with proteins, carbohydrates, oils, NaCl, and pH, as well as a brief description on the different protocols to assess their bioactivity both under in vivo and in vitro conditions.

“…One approach to reduce PM and improve the health of building occupants is using of heating, ventilating, and air-conditioning (HVAC) systems [19]. Among various systems, Negative Air Ion (NAI) generators have been developed because of a great potential for reduce PM [20,21], air microbial load [22,23], volatile organic compounds (VOCs) [24] and to eliminate odors [25]. Further, NAI may have the potential to control hospital acquired infections (HAIs) [26].…”

The present work was conducted in a two-part study. In part I, the levels of indoor and outdoor PM 10 , PM 2.5 , and PM 1 was measured using real time GRIMM dust monitors. In part II, the performance of NAIs method was investigated on reduction of indoor concentration of PM in these residential buildings for the first time. Hourly average concentration and standard deviation (SD) of PM 10 in indoor and outdoor at residential buildings were 63.5 ± 27.4 and 90.1 ± 33.5 µg/m 3 , respectively. Indoor and outdoor concentrations of PM 2.5 in residential buildings were 39.4 ± 18.1 and 49.5 ± 18.2 µg/m 3 and for PM 1 the concentrations were 4.3 ± 7.7 and 6.5 ± 10.1 µg/m 3 , respectively. We estimated that nearly 71.47% of PM 10 , 79.86% of PM 2.5 and of 61.25% of PM 1 in indoor of residential buildings can be removed by negative air ions.

“…A number of studies have shown that the utilization of EOs in their vapour phase (rather than in their liquid phase) may be an effective means of overcoming some of these limitations (Tyagi and Malik 2010, 2011a, 2011b, 2012bTyagi et al 2012a;Hyun et al 2015). EOs in their vapour phase may be able to penetrate through the cell walls of micro-organisms more effectively, and thereby exhibit stronger antimicrobial activity (Frankova et al 2014;Hyun et al 2015).…”
