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.

“…On the other hand, the cities of Bangladesh have become urban mayhem by losing living ambience. The single-storied residential buildings with open green spaces are fast disappearing and multistoried buildings are replacing them (Akteruzzaman et al 2023;Ruszczyk et al 2023). With disappearing natural habitats Bangladesh is losing its ecological balance.…”

Per capita forestland in Bangladesh is declining at an alarming rate. The recurrent anthropogenic disturbances have rendered the natural forests inhospitable for the natural regeneration and growth of wild plant associates, causing a net loss of biodiversity. Instead of native species plantation, exotic species have become an increasingly important source of timber, which negatively impacts the natural habitats. Hence, the study explored different options for native species plantation based on habitat types and the level of degradation. It is revealed that natural succession is suitable for increasing the canopy coverage in natural forest areas. In the core and buffer zones of each forest natural regeneration should be facilitated to maintain the ecological balance and to ensure continuous forest coverage. In addition, direct seeding in the buffer zone and degraded forest areas can improve the naturalness. Advanced regeneration of rare or endangered species can protect the species from extinction. Very fast-growing and timbering native species should be planted in the encroached areas. The deep-rooted species can reinforce riverbanks against erosion better than the shallow-rooted ground cover. Trees with large canopies and deep roots can protect the coastal belt. Screw pine (Pandanus) can grow on dunes and has thick ‘prop roots’ to anchor itself in the loose sand. Tanguya plantation should consist of growing annual crops along with forest trees during the early establishment of forest plantations on the hills. Fast-growing and timbering trees can increase the green cover in the fallow land. The ornamental trees simultaneously can increase the green cover and beauty in urban areas.

“…Cooking is a major contributor to indoor air pollution because the different types of foods prepared may produce a variety of volatile organic compounds (VOCs) and PM, which may cause detrimental health effects [15]. Approximately 3.8 million people worldwide die every year from illnesses attributable to the harmful indoor air from cookstoves and fuel [16].…”

Air pollution is a leading cause of death in the United States and is associated with adverse health outcomes, including increased vulnerability to coronavirus disease 2019 (COVID-19). The AirBeam2 was used to measure particulate matter with a diameter of 2.5 μm or smaller (PM2.5) to investigate differences between indoor and ambient levels at seven private homes in New York during and after the COVID-19 lockdown. Measurements taken in 2020 fall, 2021 winter, and 2022 fall showed that at 90% of the sites, indoor PM2.5 levels exceeded outdoor levels both during and after the COVID-19 lockdown, p = 0.03, possibly exceeding safety levels. Higher indoor PM2.5 levels attributed to little or no ventilation in the basement and kitchens from cooking and smoke were greater in fall than in winter. Higher ambient PM2.5 levels were attributed to vehicular traffic at a street-facing sampling site. PM2.5 sources identified in this study may help in devising control strategies to improve indoor air quality (IAQ) and consequently alleviate respiratory health effects. These findings may be used as a basis for in-house modifications, including natural ventilation and the use of air purifiers to reduce exposures, mitigate future risks, and prevent potential harm to vulnerable residents.
