“…However, this method cannot be used to identify the exact location of the 14 C label in the metabolites; thus, it is difficult to determine the detailed mechanisms of HCHO metabolism in plants. Our recent studies have shown that the treatment of plants with H 13 CHO led to a redistribution of the 13 C-labelled isotope in the metabolic network and selectively enhanced the 13 C-NMR signals in the metabolites (Song et al, 2013;Zeng et al, 2014). Therefore, 13 C-NMR analysis can be directly used to investigate HCHO metabolic mechanisms in plants.…”

“…Therefore, 13 C-NMR analysis can be directly used to investigate HCHO metabolic mechanisms in plants. Indeed, the evidence provided by 13 C-NMR analyses suggests that the Calvin cycle and C1 metabolism function independently during HCHO metabolism in Arabidopsis (Song et al, 2013), and both metabolic mechanisms are involved in HCHO-detoxification in HCHOtreated banana leaves (Zeng et al, 2014).…”

“…It is suggested that after oxidation of HCOOH to CO 2 in chloroplasts it later may be directly assimilated by the Calvin cycle into sugars [24]. The HCHO-derived 13 C-or 14 C-labeled carbon incorporated in glucose (Gluc), fructose (Fruc) and sucrose (Suc) was detected in several studies [7,25,26]. Regarding the quantitative analyses of sugars in plants treated with HCHO, it is suggested that at the beginning of the treatment sugars are used as an energy source to plant defense response to formaldehyde, and then are regenerated with the HCHO-delivered carbon [25,26].…”

Chlorophytum comosum L. plants are known to effectively absorb air pollutants, including formaldehyde (HCHO). Since the metabolic and defense responses of C. comosum to HCHO are poorly understood, in the present study, biochemical changes in C. comosum leaves induced by 48 h exposure to exogenous HCHO, applied as 20 mg m−3, were analyzed. The observed changes showed that HCHO treatment caused no visible harmful effects on C. comosum leaves and seemed to be effectively metabolized by this plant. HCHO application caused no changes in total chlorophyll (Chl) and Chl a content, increased Chl a/b ratio, and decreased Chl b and carotenoid content. HCHO treatment affected sugar metabolism, towards the utilization of sucrose and synthesis or accumulation of glucose, and decreased activities of aspartate and alanine aminotransferases, suggesting that these enzymes do not play any pivotal role in amino acid transformations during HCHO assimilation. The total phenolic content in leaf tissues did not change in comparison to the untreated plants. The obtained results suggest that HCHO affects nitrogen and carbohydrate metabolism, effectively influencing photosynthesis, shortly after plant exposure to this volatile compound. It may be suggested that the observed changes are related to early HCHO stress symptoms or an early step of the adaptation of cells to HCHO treatment. The presented results confirm for the first time the direct influence of short time HCHO exposure on the studied parameters in the C. comosum plant leaf tissues.

A B S T R A C TIn this study, coal-based granular activated carbon loaded with MnO 2 (ACLM) was tested as adsorbent for the removal of formaldehyde from aqueous solution. The ACLM was characterized by scanning electron microscopy, energy dispersive X-ray spectrometry, Brunauer-Emmett-Teller, and Fourier transform infrared spectra. The optimized pH of formaldehyde adsorption was 7.0. The removal percentage increased from 21.8 to 72.1% by raising the ACLM dosage from 0.1 to 1.0 g. The formaldehyde adsorption rate increased a little at initial formaldehyde concentrations from 0.6 to 1.8 mg/L. The adsorption equilibrium time was 24 h. The adsorption rate of formaldehyde increased from 58.1 to 61.2% with temperature rising from 298 to 308 K and decreased from 61.2 to 54.0% when temperature from 308 to 318 K. Isotherm modeling revealed that Langmuir equation could better describe the adsorption of formaldehyde onto the ACLM and the maximum adsorption capacity obtained was 4.53 mg/g. Kinetic data efficiently fitted with the pseudo-second order. The decrease of ΔG˚from 298 to 308 K suggested more favorable of formaldehyde adsorption onto the ACLM and increase of ΔG˚from 308 to 318 K revealed that the sorption was more unfavorable. Results from this study suggest that ACLM is an effective adsorbent for the removal of formaldehyde from aqueous solution in drinking water treatment field.
