“…As numerous studies show, air humidity has a significant impact on the number and composition of the air microflora [1, 17,22,23]. The results of analyses presented in Table 3 confirm that the higher the air humidity, the higher the share of fungi in the bioaerosol.…”

The indoor air quality is of great importance for the health of people. Appropriate selection of methods, parameters and conditions for the analysis makes it possible to obtain the results that reliably reflect the actual state of affairs. The aim of this study was to compare the results of microbiological air analysis in selected rooms of the Biotechnology Center obtained using the sedimentation method and the impaction method. During the research, the SMA (for total bacteria number) and Sabouraud media (for total fungi number) were exposed to different times in sedimentation analysis and to different air volumes in the impaction method. In the case of the sedimentation method, significant differences were found in the total number of bacteria and fungi in 3 out of 7 rooms depending on the time of exposure. In the case of the impaction method, it was 4 out of 7 rooms for bacteria and 2 out of 7 for fungi, depending on the analysed volume of air. The comparison of the methods showed that 4 out of 6 rooms had higher number of microorganisms when impactor was used.

“…Proper ventilation rates to exhaust pollutants from the building can lower health effects on workers, in addition to improving temperature and humidity indoors [4,6,16,21,[27][28][29]. Thus, further study on ventilation effectiveness is required to identify the issues in SME food enterprises so that corrective actions can be taken.…”

Assessment of Indoor Air Quality in Small and Medium Food Industries and Effects towards Perceived IAQ Symptoms

et al. 2023

Background: Cooking activities generate pollutants that can cause adverse health effects to occupants. This study aims to characterize the indoor air environment in small and medium food enterprises (SMEs), as studies in this area are scarce. Methods: A series of field measurements were conducted to investigate the IAQ at 14 SMEs selected in Pulau Pinang for three different cooking methods (frying, boiling, and baking). Data on environmental perception and health symptoms were obtained from 76 workers by using a validated questionnaire. Boosted regression tree (BRT) analysis and parametric tests were performed to evaluate the impact of the IAQ on the prevalence of disease symptoms. Results: The results showed that CO2, temperature, and relative humidity were higher than the standard limits, while PM2.5 and TVOC were below the standard limits. Using BRT analysis, CO2 was indicated as the highest pollutant to cause complaints by workers (41.55%), followed by CO (21.93%), relative humidity (11.81%), temperature (10.66%), PM2.5 (7.07%), and TVOC (6.99%). This study indicated that workers in SMEs food industries are affected by the indoor air quality at their workplace in which CO2 was the main parameter influencing their health. This study suggests that future research focuses on boiling and frying SMEs with CO2, CO, temperature, and relative humidity to be afforded emphasis.

“…Radon is a ubiquitous gas that forms from the decay of naturally occurring uranium ( Clement et al, 2010 ; Darby et al, 2005 ; Kang et al, 2019 ; Vogeltanz-Holm and Schwartz, 2018 ), and it can accumulate to hazardous levels in homes ( Laquatra and Laquatra, 2018 ; Riudavets et al, 2022 ; Sethi et al, 2012 ; Vogeltanz-Holm and Schwartz, 2018 ). In fact, 1 in 15 homes in the United States is estimated to have radon levels exceeding the action limit recommended by the Environmental Protection Agency, which is an indoor concentration equal to or greater than 4.0 pCi/L ( United States Environmental Protection Agency, 2016 ).…”
