“…Formaldehyde (FA) is a significant indoor air pollutant in China due to its use in various products such as food, paints, wood processing, furniture, disinfectants, and preservatives (Wang et al, 2022; Ge et al, 2020; Sakr et al, 2003; Wu et al, 2013; Zhu et al, 2022; Lin et al, 2022; Tang et al, 2015). As a result of its emission from these products, it has been identified as a common air pollutant in gymnastics practice rooms.…”

This toxicology study was conducted to assess the impact of formaldehyde, a common air pollutant found in Chinese gymnasiums, on the brain function of athletes. In this research, a total of 24 Balb/c male mice of SPF-grade were divided into four groups, each consisting of six mice. The mice were exposed to formaldehyde at different concentrations, including 0 mg/m3, 0.5 mg/m3, 3.0 mg/m3, and 3.0 mg/m3 in combination with an injection of L-NMMA (NG-monomethyl-L-arginine), which is a nitric oxide synthase antagonist. Following a one-week test period (8 h per day, over 7 days), measurements of biomarkers related to the nitric oxide (NO)/cGMP-cAMP signaling pathway were carried out on the experimental animals post-treatment. The study found that: (1) Exposure to formaldehyde can lead to brain cell apoptosis and neurotoxicity; (2) Additionally, formaldehyde exposure was found to alter the biomarkers of the NO/cGMP-cAMP signaling pathway, with some changes being statistically significant ( p < 0.05 or p < 0.01); (3) The use of L-NMMA, an antagonist of the NO/cGMP-cAMP signaling pathway, was found to prevent these biomarker changes and had a protective effect on brain cells. The study suggests that the negative impact of formaldehyde on the brain function of mice is linked to the regulation of the NO/cGMP-cAMP signaling pathway.

Different methods and technologies of measuring atmospheric concentrations of formaldehyde have been proposed in recent years. When developing formaldehyde monitoring systems based on various sensors and technologies indoors and outdoors, emphasis is placed on such parameters as ease of operation, detection limits, cost, formaldehyde selectivity, and real-time monitoring. The patent landscape, an analysis that provides a snapshot of the patent situation of a specific technology, is applied to discover the trend of technologies that focus in a particular geography, industry, or a parent technology. Patent documentation on methods, technologies, and sensors designed to detect formaldehyde in the environment was searched for and analyzed The patent landscape was conducted, including the evaluation of patent documents by country, date, technology, methods, size, the automation of equipment, and patent classification by International Patent Classification. The study reveals that China has the largest number of registered patents. The market for patent technologies is principally dominated by analyzers for accurate and automatic determination of formaldehyde. Whereas electrochemical sensors are the most common technology used in sensor development.
