“…Based on the previous research, areca palm trees can increase O 2 concentrations from 18.56% to 21.33% after 7 h and decrease CO 2 concentrations from 428 ppm to 419 ppm [65]. The ratio of the absorption of CO 2 and the emission of O 2 for a given fixed time period is 3:1 (Table 1) [61].…”

The objective of this paper is to investigate the effect of improving indoor air quality with indoor plants. As a methodology, two target classrooms with the same size (120.64 m2) and 32 students per room were selected. Then, 48 areca palm pots (average leaf area of 300 cm2/pot) were placed, and the plant density was 14.68% of the floor area. Subjective assessment for general questions, learning motivation, perceived air quality, and SBS symptoms was conducted at 5 min after the class started and 5 min before the class ended. The results showed that the CO2 concentration by respiration of the students (average of 1873 ppm) exceeded the regulatory standard (1000 ppm), but the students did not recognize the indoor CO2 concentration. The increase in CO2 concentration in the classroom was lower in the case with plant placement (624 ppm) compared with the case without plant placement (about 1205 ppm). It was statistically proven that the CO2 concentration by respiration could be reduced by 50% if the indoor plant leaf area density were maintained at about 14.68% of the floor area. In the case with plant placement, the students perceived the indoor air quality to be 40% fresher and showed a 140% higher acceptability. Moreover, the complaining of SBS symptoms was improved by 108%, and the students’ perception that it was better to focus on learning increased by about 120%. As the awareness of sustainability increases, indoor plants will be more actively placed in the United Arab Emirates. Indoor plants not only provide a visual green effect to improve human comfort but also purify indoor air pollutants.

Epigenetic Regulation in Exposome-Induced Tumorigenesis: Emerging Roles of ncRNAs

et al. 2022

Environmental factors, including pollutants and lifestyle, constitute a significant role in severe, chronic pathologies with an essential societal, economic burden. The measurement of all environmental exposures and assessing their correlation with effects on individual health is defined as the exposome, which interacts with our unique characteristics such as genetics, physiology, and epigenetics. Epigenetics investigates modifications in the expression of genes that do not depend on the underlying DNA sequence. Some studies have confirmed that environmental factors may promote disease in individuals or subsequent progeny through epigenetic alterations. Variations in the epigenetic machinery cause a spectrum of different disorders since these mechanisms are more sensitive to the environment than the genome, due to the inherent reversible nature of the epigenetic landscape. Several epigenetic mechanisms, including modifications in DNA (e.g., methylation), histones, and noncoding RNAs can change genome expression under the exogenous influence. Notably, the role of long noncoding RNAs in epigenetic processes has not been well explored in the context of exposome-induced tumorigenesis. In the present review, our scope is to provide relevant evidence indicating that epigenetic alterations mediate those detrimental effects caused by exposure to environmental toxicants, focusing mainly on a multi-step regulation by diverse noncoding RNAs subtypes.

“…Some studies showed that after placing the plants indoors CO 2 levels were increased and got stabilized (Jung & Awad, 2021;H. Kim et al, 2016;Smith & Pitt, 2011) whereas few studies noted a continuous decreasing trend (Bhargava et al, 2021;Pamonpol et al, 2020;Pegas et al, 2012). Plants help achieve thermal comfort and it was observed that the effect of plants on thermal comfort was not reduced overtime or by season (Mangone et al, 2014).…”

“…Thus, urban areas are often associated with poor air quality. In India, pollution emerges from households and ambient air, thereby majority of the population is exposed to indoor and outdoor pollution (Bhargava et al, 2021). In the year 2017, the number of deaths due to air pollution (both indoor and outdoor) in India were about 1.2 million (Health Effects Institute 2019).…”

Urbanization in Indian metropolitan cities deteriorating the outdoor environment by polluting water, soil, and air to a great extent. Some of the cities are at a fatal level of contamination affecting indoor environments. Many studies had reported the impact of a high level of CO2 indoors on the occupants. Its effect depends upon the concentration of CO2, the duration of exposure, and the concentration of oxygen (O2). Still the effects range from increased respiratory rates to cardiac ailments and carcinoses. India is a developing country so the sustainable and affordable approaches will be more applicable in this context. This study tries to find a well-grounded way to improve indoor air quality. The current pilot study focuses on examining the effect of indoor plants on indoor air quality by measuring CO2 levels. This study has used three different species of plants for three different classrooms of higher education institutes. The study was performed in an unsealed environment where air velocity and CO2 were measured. Statistical analysis results show that indoor CO2 concentration has been reduced by 11% than outdoors after placing the plants. This study also shows the correlation between CO2 concentration and the distance from the plant using the Pearson correlation coefficient. Hence indoor vegetation can be considered a sustainable way of purifying the air and altering the microclimate of the classrooms for the well-being of the occupants.
