“…Aromatic chemicals such as benzene, toluene, and xylene (BTX) pose significant health risks indoors and outdoors. Chronic and acute exposure to benzene(C6H6) can cause symptoms such as headaches, dizziness, eye and respiratory tract irritation and illness such as low RBC (Red blood cells) count and aplastic anemia [34,35].International agency for research on cancer [36] categorized benzene as a category 1 carcinogen. Inhaling toluene has been linked to symptoms such as Central Nervous System (CNS),cardiac arrhythmia, sore throat, depression and upper respiratory tract irritation [37,38].…”

Total volatile organic compounds (TVOCs),respiratory suspended particulate matter (RSPM) i.e. (PM10,PM2.5) and fine particulate matter (FPM) i.e.PM1 have been found to exert negative impact on the women health, and may even lead cancer on prolonged exposure. Since women spend most of their time indoors, they are at greater risk of indoor pollution. This study was conducted to see the effect of indoor RSPM, FPM and TVOCs on women health predominantly on young women dwellers (specifically categorized into pre-teenagers i.e., 8–12 years, teenagers i.e., 13–19 years and post-teenagers i.e., 20–21 years). Indoor monitoring was conducted from November 2022 to February 2023 in six different urban households of Lucknow, capital city of most polluted and populated state of India. Envirotech APM 550 for RSPM, APM 577 for FPM and portable sensors (BR-SMART) were used to measure TVOCs. The highest average indoor concentrations was found to be 250.1 ± 14.11µg/m3 (PM10) at Rajajipuram, 140.62 ± 19.71µg/m3 (PM2.5) at Indranagar, 27.60 ± 1.87µg/m3 (PM1) and 934 ± 70.41 µg/m3 (TVOCs) at Kaiserbagh. To elucidate the spatial dynamics of these pollutants, the Inverse Distance Weighting (IDW) interpolation technique was employed. Additionally, site-specific analysis of PM mass ratios (PM2.5/PM10, PM1/PM2.5 and PM1/PM10) elucidated the particle size distribution and their sources, such as vehicle emissions and secondary aerosols, significantly enhancing the scientific understanding of aerosol dynamics in these urban settings. The study utilised sophisticated statistical methods in it’s source apportionment analysis to identify and measure the specific contributions of various indoor sources to the total pollution levels. Health risk assessment was also determined using average daily dose (ADD), excess lifetime cancer risk (ELCR) and hazard quotient (HQ) for carcinogenic and non-carcinogenic risk. ELCR values for PM1 and PM2.5 surpassed the permissible limit in every house, demonstrating a probable cancer-causing risk and HQ value also exceeded the minimum allowable value for 20–21 year age group at all of the locations, indicating substantial health risk from exposure. International Committee of Radiological Protection Model (ICRP) and Multiple Path Particle Dosimetry (MPPD) modeling were used to see the regional deposition of PMs on the young women dwellers. The ICRP results showed that deposition is higher for PM10 in head airways and results of MPPD revealed that the highest deposition in pulmonary region was tend to be in post teenagers, whereas, highest deposition in head region was in pre teenagers and teenagers. Hence, consociate to harmful pollutants at these stages might be tremendously hazardous which are often overlooked. According to the study, the results are very alarming and concerning, the indoor air exposure to PMs and TVOCs may raise the risk of various diseases in young women and may ultimate lead to cancers. High concentration exposure during young age is very harmful and may be a cause of various diseases during their motherhood and even cause concerning and problems in new borns.

“…Benzene is also an indoor environmental toxicant which comes from furniture painting, wall painting, and decoration materials (Isinkaralar 2022 ). The concentration of benzene in the indoor air in the kitchen or industrial site may exceed the national standard by tens or even hundreds of times (Natarajan et al 2022 ). In recent years, people have spent much time indoors due to the wide spread of the COVID-19 virus, and the health risks caused by indoor air pollution are increasing (Ptbsb et al 2020 ).…”

Phytoremediation is considered an effective method for indoor air pollution control. The removal rate and mechanism of benzene in air by two plants, Tradescantia zebrina Bosse and Epipremnum aureum (Linden ex André) G. S. Bunting, were investigated through fumigation experiments under the condition of plant hydroponics culturing. Results showed that the plant removal rates increased with increase in benzene concentration in air. When the benzene concentration in air was set at 432.25–1314.75 mg·m −3 , the removal rates of T. zebrina and E. aureum ranged from 23.05 ± 3.07 to 57.42 ± 8.28 mg·kg –1 ·h –1 FW and from 18.82 ± 3.73 to 101.58 ± 21.20 mg·kg –1 ·h –1 FW, respectively. The removal capacity was positively related to the transpiration rate of plants, indicating that gas exchange rate could be a key factor for the evaluation of removal capacity. There existed fast reversible transport of benzene on air-shoot interface and root-solution interface. After shoot exposure to benzene for 1 h, downward transport was the dominant mechanism in the removal of benzene in air by T. zebrina , while in vivo fixation was the dominant mechanism at exposure time of 3 and 8 h. Within 1–8 h of shoot exposure time, in vivo fixation capacity was always the key factor affecting the removal rate of benzene in the air by E. aureum . Contribution ratio of in vivo fixation in the total benzene removal rate increased from 6.29 to 92.29% for T. zebrina and from 73.22 to 98.42% for E. aureum in the experimental conditions . Reactive oxygen species (ROS) burst induced by benzene exposure was responsible for the contribution ratio change of different mechanisms in the total removal rate, which also was verified by the change of activities of antioxidant enzymes (CAT, POD, and SOD). Transpiration rate and antioxidant enzyme activity could be considered parameters to evaluate the plant removal ability to benzene and to screen plants for establishment of plant-microbe combination technology.

“…They are primarily found in construction materials and ambient air [19,20]. Long or recurrent exposure to indoor TVOCs may cause harmful effects on the human nervous, immune, and reproductive systems; cause liver and kidney damage [21]; induce asthma, wheezing, and allergies [22]; and cause cancer [7]. In 2020, TVOCs exhibited a decrease (20~66%) in North China and an increase (13~127%) in the Yangtze River Delta region [23].…”

The elderly residing in nursing homes are typically more advanced in age, have more health issues, and spend more time indoors than other elderly people. This study explored the indoor air quality in the Wanxia nursing home, the largest private nursing home in Chengdu, China, based on long-term measurement data. Air pollutant sensors measured the level of air pollution in the Wanxia nursing home from March 2021 to February 2022. This study obtained several important results: (1) The indoor air quality index (IAQI) of the Wanxia nursing home was at a low pollution level in spring, summer, and autumn, and at a moderate pollution level in winter. PM concentration played the most important role in determining indoor air quality; (2) During winter, the 24 h mean indoor concentrations of PM2.5 and PM10 were close to or even exceeded the standard limits. During winter and summer nights, indoor CO2 levels were very close to or greater than 1000 ppm. During spring and summer nights, the indoor TVOC concentrations exceeded the limit (0.45 mg/m3); (3) Apart from HCHO concentrations in autumn, the levels of other indoor air pollutants were significantly influenced by their outdoor levels. In addition, the seasonal indoor/outdoor (I/O) ratios of CO2 and TVOCs exceeded 1; and (4) Indoor CO2 levels were closely related to indoor temperature (Ta) and relative humidity (RH) in each season. PM10 concentration correlated with Ta and RH in summer, while PM2.5 concentration did not correlate with Ta and RH in winter. The indoor TVOC level positively correlated with RH. Lastly, the indoor HCHO level was minimally influenced by changes in Ta and RH. Due to the above results, this study proposes targeted strategies for improving indoor air quality in nursing homes.
