Multi-pollutant concentration measurements around a concentrated swine production facility using open-path FTIR spectrometry

Application of FTIR Spectroscopy in Environmental Studies

“…FT-IR spectroscopy coupled with other spectroscopic techniques such as AAS (atomic absorption spectroscopy) have been used to assess the impact of industrial and natural activities on air quality (Kumar et al, 2005;Childers et al, 2001).…”

“…Techniques for measuring gas pollutants such as continuous air pollutants analyzer (SO2, NO2, O3, NH3), on-line gas chromatography (GC) used simple real-time instruments to quantify gas pollutants. They need to use several sensors in order to analyze multiple gas pollutants simultaneously.FT-IR spectroscopy coupled with other spectroscopic techniques such as AAS (atomic absorption spectroscopy) have been used to assess the impact of industrial and natural activities on air quality (Kumar et al, 2005;Childers et al, 2001).In addition to the traditional transmission FTIR (T-FTIR) methods (e.g. KBr-pellet or mull techniques), modern reflectance techniques are widely used today in environmental, agricultural, pharmaceuticals, and food studies.…”

“…The pollutants concentration was in the reanges 0.1 -100 ppm. The results have led authors to conclude that the confinement barns was the significant source of ammonia emission, and the waste treatment lagoon was the major source of methane (Childers et al, 2001). A similar research was performed by Hedge et al in oder to monitor methane and carbon dioxide emitted form a landfill in northern of Taiwan (Hedge et al, 2003), and Thorn et al used OP-FTIR to measure phosphine concentrations in the air surrounding the large fumigated structures of a tobacco warehouse (Thorn et al, 2001).…”

Long-Path Quantum Cascade Laser–Based Sensor for Methane Measurements

“…Open-path Fourier transform infrared (OP/FTIR) spectrometry techniques have shown a precision of 10-20 ppbv CH 4 for 10-s measurements (Griffith and Galle 2000). These systems have been deployed in the field at pathlengths of hundreds of meters for CH 4 emission measurements from agricultural facilities (Childers et al 2001). Although OP/FTIR instruments are commonly calibrated in the field with calibration spectra or calibration cells, these techniques do not necessarily account for drift within the entire pathintegrated sampling volume (Demirgian and Macha 1999;Bacsik et al 2005).…”

Fugitive Coke Oven Gas Emission Profile by Continuous Line Averaged Open-Path Fourier Transform Infrared Monitoring

“…Since the 1970s, OP-FTIRs have been commercially developed and used in air pollutant monitoring. 11 In the literature can be found many reports of successful applications of this technology, including an odor study in a swine production facility, 12 identification of fugitive VOC emission sources and estimation of emission rates at wastewater treatment facility, 13 estimation of inhomogeneous methane emissions from landfills, 14,15 measurement of phosphine in a tobacco warehouse, 16 and the measurements of air quality criteria pollutants (O 3 , CO, SO 2 , and NO 2 ) 17,18 and toxic VOCs 19 in ambient air. Other applications, including power stations, petrochemical plants, refineries, hazardous waste treatment facilities, biomass burning, agriculture emissions, roadway emissions, and metropolitan air quality studies have also been documented in a review paper by Bacsik et al 20 Advantages 14 -16 of OP-FTIR include its ability to analyze many compounds simultaneously and continuously, and its long path length monitoring, which has been found to be more advantageous in obtaining more comprehensive data than the traditional multiple single-point monitoring methods.…”
