“…In this study, the inhalation dose and deposition dose were calculated using the number of concentrations obtained by Grimm 1.109 OPC based on the International Commission on Radiological Protection (ICRP) model [27,28]. The ICRP model can be applied to aerosol particles and vapors from an atomic size up to very coarse aerosols (with an activity median aerodynamic diameter of 100 µm) in all practical conditions [6]. This model is designed to predict regional deposition based on the respiratory system in different subjects, including age and sex.…”

“…In other words, 1-2 days after a certain level of air pollution, children were more likely to go to the emergency room for mentally-related reasons [5]. In addition, it has already been confirmed that particles that have 2 of 18 penetrated into the respiratory tract [6] interact with each other to affect blood cells as well as brain cells [5,7].…”

“…During indoor and outdoor air quality monitoring, it was confirmed that outdoor harmful pollutants were penetrating indoors [21]. Inhalable aerosols that have penetrated the respiratory tract have different deposition rates [6,16] depending on the location of the respiratory system, and deposition levels and transport patterns provide important clues for assessing the potential health effects of aerosols [15,18].…”

“…On the other hand, the biological fraction (bioaerosol) among the various components of PM [13] can have a significant impact on human health [6,[13][14][15][16], including infectious diseases, acute toxic effects, allergies and cancer [14,17,18]. Many bacterial infectious diseases such as Legionellosis, Tuberculosis, Anthrax, etc., are due to chronic and even temporary exposure to bioaerosols [19].…”

“…In various environments (hospitals, animal warehouses, clean rooms, pharmaceutical facilities, etc.) [6,17], from birth to death, the presence of bioaerosols has been shown to impact human health, especially including multiple determinants (cooking, varied types of kitchen set) [6,15,20]. Exposure levels vary depending on the structural characteristics of houses, ventilation, location of the house [15,21,22], geographical conditions and exposure time [18].…”

Since poor air quality affects human health in the short and long term, much research has been performed on indoor and outdoor aerosol exposure; however, there is a lack of specific data on the exposure and health risks of inhalable aerosols that contain bioaerosol in different environments of human life. To investigate the potential exposure to inhalable aerosols (in the monitoring of particulate matter (PM) based on R modeling, variations of PM depend on the ventilation system and bioaerosols based on size distribution) in various environments, the special viability and culturability of bioaerosols and their deposition doses in the respiratory system were evaluated. We conducted exposure assessments on inhalable aerosols in various indoor environments (childcare facilities, schools, commercial buildings, elderly and homes). The fractions of PM (PM10, PM4 and PM2.5) were investigated and, for the bioaerosol, the viability, culturability, inhalation daily dose and the deposited dose of the aerosol in the respiratory system were calculated to evaluate the human health effects. For two years, the distribution of the indoor PM concentration was high in all PM fractions in schools and commercial buildings, and low in the elderly and at homes. For airborne bacteria, the highest concentrations were shown in the childcare facility during the four seasons, while airborne fungi showed high concentrations in the buildings during the spring and summer, which showed significant differences from other investigated environments (between the buildings and elderly and homes: p < 0.05). The viability and culturability for the bioaerosol showed no significant difference in all environments, and the correlation between inhalable PM and bioaerosol obtained from the six-stage impactor showed that the coefficient of determination (R2) between coarse particles (PM10–2.5, the size of stage 2–3) and cultivable airborne bacteria ranged from 0.70 (elderly and homes) to 0.84 (school) during the summer season.

Indoor environments pose a significant health risk due to exposure to particulate matter (PM), leading to various diseases and premature deaths, and raising public concerns about indoor air quality. Household kitchens are a major contributor to indoor air pollution, emitting particulate matter of varying sizes during cooking, which disperses throughout the house. Understanding the extent of PM exposure and identifying its sources is crucial. This study assesses PM presence in Kuwaiti household kitchens, measuring concentrations of different‐sized particles (PM 0.3, 0.5, 1.0, 2.5, 5.0, and 10 μm) under various conditions. Measurements were taken for 24 h using a particle/mass monitor device, considering different ventilation scenarios, cooking oils, and methods. Spearman's rank correlation and indoor/outdoor (I/O) ratios investigate the correlation between indoor and outdoor PM exposure. Principal component analysis (PCA) models identify specific sources contributing to PM exposure. A questionnaire survey in Kuwaiti households determines primary kitchen sources during cooking. Results show that kitchens with ventilation systems consistently reduce PM concentrations. PM emissions during cooking vary based on factors like cooking method, energy type, cooking oil, food, additives, temperature, and ventilation. The cooking stove is the primary emission source, but other household activities contribute. This study enhances our understanding of influential factors affecting cooking emissions and their concentrations, contributing valuable insights into mitigating indoor air pollution.
