“…Personal sampling was conducted in the breathing zone of pathologist, lab technicians, and housekeeping staff to measure the occupational exposure levels of formaldehyde in the pathology labs of the four hospitals. The method prescribed by the National Institute for Occupational Safety and Health (NIOSH 3500) was employed to monitor formaldehyde exposure 12 , 13 . The sensitivity of this method is considered satisfactory and reliable for detecting formaldehyde decomposition in peripheral samples due to its low detection limit of 0.5 μg and the samples’ stability for 30 days at 25 °C.…”

“…The elevated cancer risk remained below 1.0 × 10 −6 , suggesting that inhalation exposure to formaldehyde did not result in adverse health effects. However, the hazard index exceeded 1, affirming that exposure to soil containing formaldehyde led to detrimental health impacts 12 . Protano et al conducted a systematic study aiming to investigate the carcinogenic effects of formaldehyde in occupational exposures.…”

Formaldehyde, a known carcinogenic compound, is commonly used in various medical settings. The objective of this study was to assess the carcinogenic and non-carcinogenic risks associated with occupational exposure to formaldehyde. This study was conducted in the pathology labs of four hospitals in Tehran. Cancer and non-cancer risks were evaluated using the quantitative risk assessment method proposed by the United States environmental protection agency (USEPA), along with its provided database known as the integrated risk information system (IRIS). Respiratory symptoms were assessed using the American thoracic society (ATS) questionnaire. The results indicated that 91.23% of exposure levels in occupational groups exceed the NIOSH standard of 0.016 ppm. Regarding carcinogenic risk, 41.03% of all the studied subjects were in the definite carcinogenic risk range (LCR > 10−4), 23.08% were in the possible carcinogenic risk range (10−5 < LCR < 10−4), and 35.90% were in the negligible risk range (LCR < 10−6). The highest index of occupational carcinogenesis was observed in the group of lab technicians with a risk number of 3.7 × 10−4, followed by pathologists with a risk number of 1.7 × 10−4. Furthermore, 23.08% of the studied subjects were within the permitted health risk range (HQ < 1.0), while 76.92% were within the unhealthy risk range (HQ > 1.0). Overall, the findings revealed significantly higher carcinogenic and non-carcinogenic risks among lab technicians and pathologists. Therefore, it is imperative to implement control measures across various hospital departments to mitigate occupational formaldehyde exposure levels proactively. These findings can be valuable for policymakers in the health sector, aiding in the elimination or reduction of airborne formaldehyde exposure in work environments.

“…A dynamic multimedia environmental model was established to identify the environmental behaviors of hazardous pollutants in the air, soil, and water, depending on the changing climate, by assuming abnormal conditions. This study reflected the movement of a hazardous pollutant via the air and established a model for soil and water, considering various conditions, including the impact of sedimentation (Park et al, 2020). The area for modeling was set as 15 km x 12 km, and the nested grid in the area was set as 0.1 km x 0.1 km.…”

“…Under the Ministry of Environment(MOE), the National Institute of Chemical Safety(NICS) provides the estimated areas affected by chemical accidents in the Chemical Accident Response Information System(CARIS) and makes efforts to reduce damages arising from chemical accidents (Kim et al, 2020). Additionally, it was reported that local residents lived within 1 km of some of the recent chemical accidents in Korea, and that the accidents posed a serious hazard to the residents, making it necessary to develop a method that can predict and assess the impact of a chemical accident on the health of local residents (Park et al, 2020).…”

We established a hypothetical acrylic acid leak accident scenario, conducted a health risk assessment of local residents, and compared an actual accident case and the hypothetical scenario. The exposed subjects were divided into four age groups, and a non-carcinogenic risk assessment was conducted for inhalation and soil ingestion. In the hypothetical scenario, 40 tons of acrylic acid were leaked in Ulsan for 1 h from 12:00 am on January 1, 2017, and in the actual accident case, 3 L of acrylic acid were leaked in Hwaseong, Gyeonggi Province, for 1 h from 11:00 am on March 5, 2020. The environmental concentration of acrylic acid was calculated using the dynamic multimedia environmental model. Non-carcinogenic assessment of the hypothetical scenario showed the hazard index exceeded 1 across all age groups, suggesting that a health risk is likely to occur due to inhalation exposure to acrylic acid resulting from a chemical accident. Hazardacute exceeded 1 until 2 h after the accident under the hypothetical scenario, indicating the likelihood of a health risk. Thus, we propose a methodology that can assess changing concentrations in a hazardous chemical leak from a chemical accident based on the time, place, the chemical’s behaviors in different environmental media, and the health risk posed by the exposure of the chemical to local residents in the area affected by the accident.

“…Formaldehyde is a kind of toxic gas that is harmful to human health. Occasionally formaldehyde inhalation up to a certain amount usually causes headache and limb fatigue, and a long term severe inhalation of formaldehyde ultimately damages the human being's kidneys and other organs, even destroys the brain nerve system [1,2]. The research on rapid detection of formaldehyde can contribute to early prevention and treatment of its pollution and therefore beneficial to the healthcare of the person who may contact this harmful substance by chance.…”

High performance formaldehyde gas sensors are widely needed for indoor air quality monitoring. A modified layer of zeolite on the surface of metal oxide semiconductors results in selectivity improvement to formaldehyde as gas sensors. However, there is insufficient knowledge on how the thickness of the zeolite layer affects the gas sensing properties. In this paper, ZSM-5 zeolite films were coated on the surface of the SnO2 gas sensors by the screen printing method. The thickness of ZSM-5 zeolite films was controlled by adjusting the numbers of screen printing layers. The influence of ZSM-5 film thickness on the performance of ZSM-5/SnO2 gas sensors was studied. The results showed that the ZSM-5/SnO2 gas sensors with a thickness of 19.5 μm greatly improved the selectivity to formaldehyde, and reduced the response to ethanol, acetone and benzene at 350 °C. The mechanism of the selectivity improvement to formaldehyde of the sensors was discussed.
