Quantification of Non-Methane Volatile Organic Compound Emissions from California Landfills
In this study, an intensive field-testing program was conducted to quantify non-methane volatile organic compound (NMVOC) emissions from five municipal solid waste (MSW) landfills in California. Field measurements in this study were conducted during the dry season. Flux measurements for 64 NMVOC species across different cover systems at the landfills were obtained using the static flux chamber method. Negative (net uptake) and positive (net emissions) NMVOC fluxes ranging from -6.54×10−4 to 1.81×100 g/m2-day were measured across all landfills. NMVOC surface fluxes decreased from daily to intermediate to final cover systems for the majority of the sites investigated. Quantified surface fluxes were greatest for the alcohol, aldehyde/alkyne, monoterpene, alkane, and ketone NMVOC chemical families. Scaled-up NMVOC emissions for the sites ranged from 0.024 to 2.22 Mg/year, which were lower than scaled-up methane emissions (0.035 to 1,002 Mg/year). For NMVOCs, the highest emissions were measured at the landfill with the highest and lowest percentages of daily and final covers, respectively.
