Formaldehyde is a common gaseous pollutant from buildings and decorative materials. However, in recent years, increasing concerns have been raised regarding its harmful health in indoor air. Therefore, this study aims to investigate the physiological and photosynthetic response mechanisms of Racomitrium japonicum under formaldehyde stress. R. japonicum was exposed to dynamic fumigation with formaldehyde for 7 days, with each day comprising an 8-h exposure period within a sealed container. The effects on plant structure, pigment content, photosynthetic efficiency, and reactive oxygen species (ROS) generation were assessed. Our findings revealed that formaldehyde stress led to structural damage, reduced pigment content, decreased photosynthetic efficiency, and increased ROS production in R. japonicum. Significantly, distinct stress-response pathways were observed at various formaldehyde concentrations. In response to low and moderate formaldehyde concentrations, R. japonicum activated its antioxidant enzyme system to mitigate ROS accumulation. In contrast, the high-concentration treatment group demonstrated suppressed antioxidant enzyme activity. In response, R. japonicum used non-photochemical quenching and activated cyclic electron flow to mitigate severe cellular damage. This study provides an in-depth understanding of the physiological changes of R. japonicum under formaldehyde stress, elucidating its response mechanisms. The findings provide valuable information for developing effective indoor formaldehyde monitoring and purification methods.

“…Various research studies have reported formaldehyde to adversely affect plants by causing destruction of spongy parenchyma and palisade cells, necrosis, stomatal damage, decreased peroxidase and catalase activity in Rhapis excelsa, Epipremnum aureum and Ficus japonica (Kim et al 2013), enhanced plasma membrane permeability in Tillandsia velutina (Li et al 2015), leaf injury in Davallia bullata and Nephrolepis exaltata (Wang et al 2020), reduced chlorophyll content in Peperomia tetraphylla and Dracaena sanderiana and lower water soluble sugars in C. comosum (Wang et al 2020). Plants also respond to the applied formaldehyde by activating its enzymatic machinery such as higher catalase, peroxidase and total antioxidant activity in C. comosum (Li et al 2019); induction of redox and antioxidative enzymatic activities in Taraxacum mongolicum and Plantago asiatica ). It's well-known that under different stresses including formaldehyde, plants produce a relatively higher amount of reactive oxygen species (ROS).…”

“…Moreover, GPX is also a prominent antioxidant enzyme known to eliminate excessive H 2 O 2 which thus aids the plant to withstand stressful environment (Asada 1999). Higher T-AOC is reported to aid plants in coping up various stresses (Li et al 2019). TAOs are stable molecules known to donate an electron to a rampaging free radical and neutralize it.…”

Formaldehyde is a prominent volatile organic compound and also considered an indoor air pollutant. Chlorophytum comosum, an indoor plant, has been reported to metabolize indoor formaldehyde. But the phytotoxic effects of formaldehyde, being a pollutant, on C. comosum is not well explored. Furthermore, C. comocum responses that can be considered as markers at the physiological and biochemical level against formaldehyde stress are not yet investigated. Therefore, the current research study was aimed to evaluate such potential markers against formaldehyde in C. comosum. Briefly, C. comosum was exposed to 5, 10, and 20 ppm formaldehyde doses in an airtight glass chamber. Plant samples were then taken to analyze morpho-anatomical, physiological, and biochemical responses after short (2, 4, and 6 hours), medium (12 and 24 hours) and extended durations (48 and 96 hours) for each tested dose. Two-ways ANOVA followed by Tukey’s test at p ≤ 0.05 indicated that application of 10 and 20 ppm formaldehyde doses led to a significant incline in enzymatic antioxidants like CAT, GPX and SOD, and non-enzymatic parameters including TPC, TFC, T-AOC, carotenoids and intercellular CO2. However, formaldehyde application negatively affected the physiological responses of C. comosum by reducing its photosynthetic rate, transpiration rate and stomatal conductance. Additionally, extended exposure of C. comosum to 10 and 20 ppm formaldehyde doses led to visible leaf damage. Principal Component Analysis indicated that enzymatic (SOD, CAT and GPX) and non-enzymatic (MDA, TPC, TFC, TAO, carotenoids, TSS and intercellular CO2) parameters contributed the most to the total variance. Thus, these parameters have potential to serve as physiological and biochemical markers in C. comosum against formaldehyde stress.

Formaldehyde is an important pollutant that endangers human physical and mental health. Currently, fabrics used in architectural design only serve as space beautification. How to combine environmental protection, antibacterial materials and building materials to develop beautiful and clean building materials is an urgent need. Nano-TiO2 composite coatings are of great significance in architectural design because of their good stability, non-toxicity, and good degradation of formaldehyde. In this paper, the performance of nano-TiO2 composite coating and nano-TiO2 in degrading formaldehyde was compared, mainly in the three cases of finishing agent concentration, temperature and initial formaldehyde concentration. The results showed that the nano-TiO2 composite coating had better degradation effect on formaldehyde than nano-TiO2. The formaldehyde degradation rate of composite coatings has been increased by 20% compared with nanometers. At 20-60 degrees Celsius, the degradation rate of nanocomposite coatings relative to nanoformaldehyde has increased by 5%. It also shows that nano-TiO2 composite coating is more suitable for use in architectural design, which can better ensure people's physical and mental health.
