Settled house dust (SHD) is a reservoir for various contaminants, including endocrine‐disrupting chemicals (EDCs), trace metals, and house dust mite allergens. This study aimed to characterize various chemical and biological contaminants in SHD and identify determinants governing the indoor contaminants. In total, 106 SHD samples were collected from 106 houses in Seoul and Gyeonggi Province, Korea, in 2021. Bedding dust samples were collected from 30 of these 106 houses. All participants completed a questionnaire comprised of housing and lifestyle‐related factors. The samples were analyzed for 18 organophosphate flame retardants (OPFRs), 16 phthalates, five alternative plasticizers (APs), seven trace metals, and two house dust mite allergens (Dermatophagoides farinae type 1 [Der f1] and Dermatophagoides pteronyssinus type 1 [Der p1]). A multiple regression analysis was conducted to identify the determinants governing the concentrations and profiles of various contaminants. OPFRs, phthalates, APs, and trace metals were detected in all SHD samples, indicating ubiquitous contamination in indoor environments. Among the three EDC groups, APs were detected at the highest concentrations (geometric mean [GM] (geometric standard deviation, [GSD]): 1452 (1.6) μg/g in total), followed by phthalates (GM (GSD): 676 (1.4) μg/g in total) and OPFRs (GM (GSD): 10 (1.4) μg/g in total). Der f1 was detected in all bedding dust samples with significantly higher levels than Der p1 (GM (GSD): 0.1 (1.8) μg/g vs. 1.4 × 10−3 (2.3) μg/g). The concentrations of OPFRs, plasticizers, and trace metals in SHD were significantly associated with the type and number of electronic appliances and combustion activities. Der f1 was significantly associated with the number of occupants and water penetration. Ventilation, vacuum cleaning, and wet cleaning or dry mopping significantly reduced the levels of most contaminants in SHD. As residents are persistently exposed to a wide array of pollutants, comprehensive and adequate measures are required to prevent potential exposures.

“…In ltration of outdoor air containing suspended particulate matter, incomplete and ine cient burning of solid fuels, wind-driven or tra c related suspension of road, soil, and mineral dust, sea salt and biological materials, heating, cooking are causing the settled household-dusts that include the organic and inorganic contaminants. Among varied sources of indoor air pollution, settled dust in houses might be an important source of potential toxic metals, and indoor contaminants [1,2,4,5]. Moreover, microorganism (e.g., pathogens, allergens, bio-based toxins) in indoor dust are more likely to introduce human lungs, triggering serious health conditions [6] (Wu et al 2021).…”

In the last decade, a great deal of research has focused on the determination of potential toxic metals in indoors due to an important source of the toxicity and health risks. The previous studies have commonly focused determination of total concentration of metals and identification the microorganisms in dust. On the other hand, determination bio-relevant forms (e.g., inhalable) of metals instead of total contents, examination the behavior of microorganism under these bio-relevant conditions and revealing the interaction between metals and pathogens is vital and necessary for realistic approach. However, previous studies have been ignored these topics in this field. Therefore, the present study aimed to (i) investigate metals in household dusts extracted in simulated body fluids by inhalation, (ii) examine the culturable pathogen responses in the presence of household dusts extracted in simulated body fluids, and (iii) assess their relations and risks using the model approaches by inhalation. Here, 25 household-dusts were extracted in four simulated body fluids to determine bio-relevant forms of metals (specifically using inhalation fluids). Moreover, four clinically important pathogens were incubated in the presence of household-dusts extracted in simulated body fluids. The activity, biofilm, biochemical and oxidative responses of pathogens were measured following household-dust exposures. Afterward, the relationship between metals and pathogens responses were evaluated, and model and derived approaches were used for risk assessments of metals and pathogens. The higher daily intake metal values obtained in artificial lysosomal fluid fraction of household dust that mimicking the inflammatory condition compared to other body fluids. The highest risk of the pathogens originated by biofilm formation.

“…In recent years, House dust contaminated with heavy metals has received more and more attention as it relates to health of human. A numerous studies have been performed to evaluate the metals concentrations in household dust around the world, e.g., India (Kumar and Scott, 2009;Yaparla et al, 2019 ), Australia (Chattopadhyay et al, 2003), Turkey (Kurt-Karakus, 2012 ), China (Zhao et al, 2020, Cheng et al, 2018Wang et al, 2020), Saudi Arabia (Albar et al, 2019), Iran (Sobhanardakani, 2018;Hashemi et al, 2020), Canada (Al Hejami et al, 2019, Jordan (Arar et al, 2019;Al-Madanat et al, 2017), Egypt (Jadoon et al, 2020), Nepal (Yadav et al, 2019), Trinidad, WI (Clark et al, 2020), USA (Matt et al,2021).

Household dust pollution with heavy metals attracted the attention of researchers and environmental managers due to the risk of the health of these metals. The study aims are to determine heavy metals concentrations (Cd, Cr, Cu, Ni, Pb, Zn), their spatial distribution, and their potential sources in the household dust of Al-Fallujah City, Iraq. The dust was sampled from 50 houses. The heavy metals levels in the dust were measured using the atomic absorption spectrophotometry method. The mean concentration of heavy metal was ordered as following: Zn (292.85 mg/kg) > Cr (289.45 mg/kg) > Ni (105.72 mg/kg) > Pb (75.57 mg/kg) > Cu (65.03 mg/kg) > Cd (14.77 mg/kg). The mean concentration of these metals exceeded the reference values. The areal distribution of the reported heavy metals showed specific and non-specific patterns indicating point and non-point pollution sources. The heavy metals potential sources in house dust in the study area were characterized using correlation, Principle components and cluster analyses. The potential sources for Cd, Cu and Pb were interior and exterior sources, while the Ni and Cr were derived from internal sources. This study provides the environmental protection managers and decision-makers with important information about heavy metals concentrations and their sources in indoor environments.
