“…Many studies have confirmed that indoor air quality is highly affected by outdoor air quality (Leung, 2015). As our population continues to urbanize, the number of people spending 80-90% of their time indoors 52 is also increasing (Orwell, 2004). Many studies have reported that the concentrations of volatile organic compounds are higher indoors than outdoors (Sakai et al, 2004).…”

“…Since many people spend most of their lives indoors, indoor air represents a major proportion of their exposure to air pollution and poor indoor air quality may pose serious health risks (Wood and Burchett, 1995). The importance of indoor air quality to human health has become of increasing interest where inhabitants often spend over 90% of their time indoors and indoor air has been reported to be as much as 12 times more polluted than that outdoors (Orwell et al 2004;Zabiegała, 2006). Indoor air pollutants include volatile organic compounds, particulate matter, ozone, radon, lead, and biological contaminants (Destaillats et al 2008) and exposure can cause acute illnesses and chronic diseases (Suh et al 2000).…”

SUMMARYVariegated foliage plants such Polka Dot Plant (Hypoestes phyllostachya) as are often used in interiorscaping in low light environments. The changes in leaf number and plant height under various light types (blue, red and blue+red LED (light-emitting diode) and fluorescent) were investigated to elucidate their optimum indoor light environment. The changes in plant height (was different from leaf number. In general, plant height increased with increasing time. Leaf number showed no significant changes in first sampling decades under different light treatments. The analysis of variance results indicated significant differences for plant height in different light treatments for all sampling decades expect the first, second and third decades, but the results of analysis of variance for leaf numbers indicated non-significant differences among different light treatments. The comparison of means for plant height in the first, second and third decades indicated that there are no significant differences among light treatments while in next five decades, red light treatment showed the long plant height. Also, comparison of means for leaf numbers under various light treatments via Duncan's new multiple range test indicated that there is not any significant differences among different light treatments in first five decades and seventh decade while in the sixth decade, blue light treatment had the highest leaf numbers following to red and blue+red light treatments. In the eighth decade, blue and red light treatments had the highest leaf numbers following to blue+ red light treatment. This study revealed that the most suitable light treatment for obtaining short and high leaf numbers in Polka Dot Plant were blue or blue+red treatments.

“…Bioprocesses, such as biotrickling filters (Lu et al, 2010), biofilters (Wolverton et al, 1984;Wolverton and Wolverton, 1993;Ondarts et al, 2012), or the use of plants (Orwell et al, 2004;Wang and Zhang, 2011), have already been successfully used to remove VOCs in effluents with constant/unvarying concentrations. By this technique, microorganisms are generally the main removal agents.…”

Bioprocesses, such as biofiltration, are commonly used to treat industrial effluents containing volatile organic compounds (VOCs) at low concentrations. Nevertheless, the use of biofiltration for indoor air pollution (IAP) treatment requires adjustments depending on specific indoor environments. Therefore, this study focuses on the convenience of a hybrid biological process for IAP treatment. A biofiltration reactor using a green waste compost was combined with an adsorption column filled with activated carbon (AC). This system treated a toluene-micropolluted effluent (concentration between 17 and 52 µg/m 3 ), exhibiting concentration peaks close to 733 µg/m 3 for a few hours per day. High removal efficiency was obtained despite changes in toluene inlet load (from 4.2 × 10 −3 to 0.20 g/m 3 /hr), which proves the hybrid system's effectiveness. In fact, during unexpected concentration changes, the efficiency of the biofilter is greatly decreased, but the adsorption column maintains the high efficiency of the entire process (removal efficiency [RE] close to 100%). Moreover, the adsorption column after biofiltration is able to deal with the problem of the emission of particles and/or microorganisms from the biofilter.Implications: Indoor air pollution is nowadays recognized as a major environmental and health issue. This original study investigates the performance of a hybrid biological process combining a biofilter and an adsorption column for removal of indoor VOCs, specifically toluene.
