“…Measurements of HCOOH have been reported using a variety of techniques. In situ techniques include a wet chemical method [ Mader et al , 1955], detection with a mass spectrometer [ Möhler et al , 1993], gas phase sampling detection using ion chromatography [ Talbot et al , 1988, 1995, 1996, 1997a, 1997b] and a condensate collection method [ Dawson and Farmer , 1980; Arlander et al , 1990]. In situ HCOOH sampling measurements with the ion chromatography method were obtained from surface sites in the eastern United States [ Talbot et al , 1988, 1995] and later over the Atlantic [ Singh et al , 2000], and the western Pacific during NASA's Pacific Exploratory Missions [ Talbot et al , 1996, 1997a, 1997b].…”

The seasonal variation of the free tropospheric volume mixing ratio of formic acid (HCOOH) has been derived from high‐spectral‐resolution solar absorption spectra recorded with the Fourier transform spectrometer in the U.S. National Solar Observatory facility on Kitt Peak (31.9°N, 111.6°E, 2.09 km altitude) at a typical spectral resolution of 0.005 cm−1. The spectra have been analyzed with the SFIT2 algorithm, which is based on a semiempirical application of the optimal estimation method. Absorption by HCOOH is weak in these solar spectra, but successful retrievals have been obtained with a new procedure that fits the HCOOH ν6 band Q branch at 1105 cm−1 simultaneously with a window to account for a temperature‐sensitive HDO line, which overlaps the HCOOH Q branch. After retaining only the best measurements from a database extending from June 1980 to October 2002 the retrievals show a seasonal variation, with a summer maximum and a winter minimum. Average 2.09–10 km volume mixing ratios binned in 3 month intervals range from a maximum of 792 ± 323 parts per trillion by volume (pptv), or 10−12, in July–September to a minimum of 313 ± 175 pptv in October–December, with the uncertainties corresponding to statistical means from daily averages. The results are compared with previously reported measurements and model calculations.

“…Atmospheric organic acids were first reported in downtown Los Angeles by using a bubbler in NaOH solution followed by silica gel column chromatography-titration (3). The concentration of formic acid ranged from 0.0 to 0.41 ppm, but that of acetic acid was not described.…”

“…Therefore, the synergy of forces in the indoor environment can be worse than weathering. In addition, the exposure to the polluted atmosphere increases the effect of weathering and enhances the breakdown of polysaccharides (Mader et al 1955;Malhotra and Khan 1984). Furthermore, the environmental pollutant gases that are claimed to diffuse into the wooden material indoor environment include those present in the outdoor macroenvironment (gallery and storage spaces) such as nitrogen oxides, ozone and other photochemical oxidants, sulfur dioxide, and particles, and indoor-generated pollutants in the microenvironment (display cases and storage cabinets) include formaldehyde, acetaldehyde, and formic and acetic acids.…”

A new perspective on the effect of unconditioned indoor (especially storage areas) and outdoor environments on wood acidity is provided in this work. A comparison between the quantity and types of the organic acids formed in the unconditioned indoor environment and different outdoor environments was made. Moreover, the acidity of some wood samples due to different environmental conditions was determined using a pH meter and high-performance liquid chromatography (HPLC). Fourier transform infrared (FTIR) was used to detect the changes in wood components at the molecular level due to environmental conditions. The results suggest that the unconditioned indoor environment was more aggressive than the outdoor environment with respect to wood deterioration. The polluted atmosphere increased the wood acidity and motivated polysaccharide breakdown.
