Abstract Women spend relatively more time in indoor conditions in developing countries. Exposure to various indoor air pollutants leads them to higher health risks according to Household air quality in which they reside. Particulate matter (PM) exposure with their exposure duration inside the household plays a significant role in women's Respiratory problems. We measured size segregated particulate matter concentrations in 63 residences at different locations. Respiratory dust depositions (RDDs) for 118 women in their different respiratory regions like head-airway (HD), tracheobronchial (TB), and alveolar (AL) region for the three PM size fractions (PM10, PM2.5 & PM1) were investigated. For different positions like Light exercise and the Sitting condition, RDD values found for AL region was 0.091 µgmin− 1 (SD: 0.067, 0.012–0.408) and 0.028 µgmin− 1 (SD: 0.021, 0.003–0.126) for PM10, 0.325 µgmin− 1 (SD: 0.254, 0.053–1.521) and 0.183 µgmin− 1 (SD: 0.143, 0.031–0.857) for PM2.5, 0.257 µgmin− 1 (SD: 0.197, 0.043–1.04) and 0.057 µgmin− 1 (SD: 0.044, 0.009–0.233) respectively for PM1 to females. RDDs values in the AL region significantly increases as PM10 (11%), PM2.5 (68%), and PM1 (21%), confirm that for women, the AL region is the most prominent affected zone by fine particles (PM2.5).

Indoor And Outdoor

People spend the majority of their time indoors, mostly in the domestic environment, where there may be significant air pollution sources. Indoor air pollutants can be derived from the ingress of contaminated air from outdoors (e.g., heavily trafficked roads, presence of industry, allergens) and from specific indoor sources such as combustion appliances, building materials, and consumer products. The activities and behaviour of individuals, for example, cooking, heating, cleaning, smoking, pets, can also influence the production and levels of indoor air pollutants. There is a body of literature concerning indoor concentrations of pollutants such as CO, NO2, formaldehyde, volatile organic compounds, house dust mites, fungi, bacteria and their health effects. However, there have been few, if any studies, conducted in the UK to date to compare and contrast indoor and outdoor particulate matter (PM). Epidemiological studies consistently suggest that increases in outdoor PMIO (particulate matter with an aerodynamic diameter of less than l0μm) concentrations are linked to health effects (morbidity and mortality in persons with cardiopulmonary diseases).

Particulate matter is one of the most important indoor air pollutants involved in a number of adverse health effects, such as premature deaths and increased mortality of infants and other parts of sensitive population. This paper focuses on investigation of metal substances of suspended as well as settled particulate matter in indoor environment. The monitoring of particulate matter concentration was carried out in three rooms of a selected flat building in the city of Košice, Slovakia. The sampling of settled particulate matter was carried out by passive methods during the period of 28 days. The investigation of suspended particulate matter investigation focused on total suspended particles (TSP) and thoracic fraction called PM10. The presence of selected metals in the samples was detected by atomic absorption spectrometry. The surface concentrations of settled particulate matter were detected in the range from 276.43 μg cm-2 to 570.70 μg cm-2, mass concentrations of total suspended particulate matter from 59.028 to 114.583 μg m-3. PM10 concentration values reached about half of the TSP concentration values (PM10/TSP ratio was from 0.48 to 0.6). Higher percentage of metals was detected in suspended particulate matter in comparison to the settled particles. Higher values were detected for all metals (except iron and zinc) in each measured room.

Indoor Air Pollutants

Urban civilization has a high impact on the environment and human health. The pollution level of indoor air can be 2–5 times higher than the outdoor air pollution, and sometimes it reaches up to 100 times or more in natural/mechanical ventilated buildings. Even though people spend about 90% of their time indoors, the importance of indoor air quality is less noticed. Indoor air pollution can be treated with techniques such as chemical purification, ventilation, isolation, and removing pollutions by plants (phytoremediation). Among these techniques, phytoremediation is not given proper attention and, therefore, is the focus of our review paper. Phytoremediation is an affordable and more environmentally friendly means to purify polluted indoor air. Furthermore, studies show that indoor plants can be used to regulate building temperature, decrease noise levels, and alleviate social stress. Sources of indoor air pollutants and their impact on human health are briefly discussed in this paper. The available literature on phytoremediation, including experimental works for removing volatile organic compound (VOC) and particulate matter from the indoor air and associated challenges and opportunities, are reviewed. Phytoremediation of indoor air depends on the physical properties of plants such as interfacial areas, the moisture content, and the type (hydrophobicity) as well as pollutant characteristics such as the size of particulate matter (PM). A comprehensive summary of plant species that can remove pollutants such as VOCs and PM is provided. Sources of indoor air pollutants, as well as their impact on human health, are described. Phytoremediation and its mechanism of cleaning indoor air are discussed. The potential role of green walls and potted-plants for improving indoor air quality is examined. A list of plant species suitable for indoor air phytoremediation is proposed. This review will help in making informed decisions about integrating plants into the interior building design.
