AI Article Synopsis
- The study investigates the long-term impact of formaldehyde fumes on lung function in health professionals working in a laboratory setting, focusing on 16 non-smoking participants who were regularly exposed for over 4 years.
- Pulmonary tests (forced spirometry and lung diffusing capacity) showed no significant differences in lung function between the exposed group and a matched control group, suggesting no harmful effects on lung capacity.
- However, the study found that the blood volume of pulmonary capillaries was significantly higher in those exposed to formaldehyde, indicating a need for further research into the potential hyperemic effects of the fumes.
Article Abstract
The present study examines long-term effects of occupational exposure to formaldehyde fumes on lung function. Forced spirometry and diffusing lung capacity were measured in 16 health-service professionals (8 medical doctors and 8 laboratory technicians) working at the pathoanatomic laboratory for at least 4 years with daily exposure 8 +/- 1 hours. Control group employed 16 males, which were matched by age and stature to members of the exposed group. Only non-smokers were included in the study. Spirometric parameters in study participants exposed to formaldehyde fumes compared to control group were not significantly different indicating absence of restrictive and/or obstructive deterioration of lung function in exposed group. The only parameter differing in two groups was blood volume of pulmonary capillaries (Vc') which was significantly larger in a group exposed to formaldehyde fumes. The possibility that the hyperemic lung reaction is the consequence of the exposure to formaldehyde fumes should be further explored.

Article Synopsis
- - This study assessed levels of cooking fumes (respirable dust, formaldehyde, and carbon monoxide) that cafeteria workers in schools might encounter, using 111 samples from 55 schools.
- - The findings showed that the median concentration of respirable dust was 38.37 µg/m3 and levels of formaldehyde and carbon monoxide remained below 20% of exposure limits, indicating a relatively safe environment.
- - A significant correlation was found between larger school sizes and higher daily cooking oil usage, which in turn related to increased respirable dust exposure among kitchen workers.

Article Synopsis
- - Cellulosic substrates like wood are popular in sustainable construction but are highly flammable; traditional fire-retardant coatings often contain harmful chemicals and are opaque, reducing aesthetics and sustainability.
- - Researchers developed a new transparent fire-retardant coating using phytic acid from rice bran and powdered chicken eggshells, which improved fire protection ratings and self-extinguishing properties without toxic fumes.
- - The new coating demonstrated better thermal stability and enhanced fire-retardancy, with no loss in adhesion strength, making it a promising alternative for safer construction materials.
Background: Worldwide, lung cancer is the second leading cause of cancer death in women. The present study explored associations between occupational exposures that are prevalent among women, and lung cancer.
Methods: Data from 10 case-control studies of lung cancer from Europe, Canada, and New Zealand conducted between 1988 and 2008 were combined.

Cooking oil fumes are an intricate and dynamic mixture containing a variety of poisonous and hazardous substances, and their real-time study remains challenging. Based on tunable synchrotron radiation photoionization mass spectrometry (SR-PIMS), isomeric/isobaric compounds in the gaseous oil fumes from oleic acid thermal oxidation were determined in real time and distinguished by photoionization efficiency (PIE) curve simulation combined with multiple linear regression (MLR) analysis. A series of common carcinogens such as formaldehyde, acetaldehyde, acrolein, and several unreported chemicals including diethyl ether and formylcyclohexane were successfully characterized.
