Volatile organic compounds (VOCs) comprise an important group of indoor air pollutants, commonly found in building materials and consumer products. Due to their low boiling points, VOCs are prevalent in indoor environments, with concentrations in homes, schools, and offices often two to five times higher than outdoors. Chronic exposure to VOCs is linked to a range of adverse health outcomes, including respiratory, neurological, cardiovascular damage, and an increased cancer risk. Children and adolescents who spend a significant amount of time in educational buildings are particularly vulnerable to these effects. Therefore, this study aimed to estimate the related health risks to those in day care centres, schools, high-schools and universities across 17 member states of the European Union (EU) by utilizing a previously published dataset and collecting data on levels of 9 VOCs. Health risks were assessed using the World Health Organization's Indoor Air Quality Risk Calculator. Point of departure indices (PODIs) and cancer risks were calculated, with values above 1.0 and 10 cases/1 million population respectively indicating an increased health risk. Our results showed that formaldehyde exposure poses an increased risk of respiratory, neurological and carcinogenic effects in educational buildings in 14 of the countries studied. Additionally, neurological risks from exposure to benzene were above the limit in 4 EU countries. These findings indicate the need to reduce formaldehyde and benzene concentrations in European educational buildings to protect the health of the next generation.

Formaldehyde, a known carcinogen prevalent in everyday environments, poses significant health risks, particularly through inhalation exposure. This study investigates the histopathological changes in the lungs of Wistar rats induced by formaldehyde at doses of 20, 30, and 40 parts per million (ppm) over a three-month period. The research aims to elucidate the onset of dysplasia, a cellular defense mechanism characterized by abnormal epithelial proliferation, as a response to carcinogenic exposure. Utilizing a post-test only control group experimental design, we observed that increased formaldehyde exposure correlates with a heightened severity of dysplasia, with a statistically significant result (p = 0.002). Our findings indicate that varying doses of formaldehyde lead to differential degrees of dysplasia, underscoring the importance of dose-response relationships in assessing the carcinogenic effects of formaldehyde on lung tissue.

Formaldehyde (gas) can cause cancer according to an independent committee of scientific and health experts.

Formaldehyde is an aldehyde resulting from the formal oxidation of methanol. It has a role as a disinfectant, a carcinogenic agent, an allergen, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, an EC 3.5.1.4 (amidase) inhibitor and an environmental contaminant. It is an aldehyde and a one-carbon compound.
