英文摘要: Reduced sulfur compounds (RSCs) emissions from concentrated animal feeding operations (CAFOs) have become a potential environmental and human health concern, as a result of changes in livestock production methods. RSC emissions were determined from a swine CAFO in North Carolina. RSC measurements were made over a period of ≈1 week from both the barn and lagoon during each of the four seasonal periods from June 2007 to April 2008. During sampling, meteorological and other environmental parameters were measured continuously. Seasonal hydrogen sulfide (H2S) barn concentrations ranged from 72 to 631ppb. Seasonal dimethyl sulfide (DMS; CH3SCH3) and dimethyl disulfide (DMDS; CH3S2CH3) concentrations were 2-3 orders of magnitude lower, ranging from 0.18 to 0.89ppb and 0.47 to 1.02ppb, respectively. The overall average barn emission rate was 3.3gday-1AU-1 (AU (animal unit)=500kg of live animal weight) for H2S, which was approximately two orders of magnitude higher than the DMS and DMDS overall average emissions rates, determined as 0.017gday-1AU-1 and 0.036gday-1AU-1, respectively. The overall average lagoon flux was 1.33μgm-2min-1 for H2S, which was approximately an order of magnitude higher than the overall average DMS (0.12μgm-2min-1) and DMDS (0.09μgm-2min-1) lagoon fluxes. The overall average lagoon emission for H2S (0.038gday-1AU-1) was also approximately an order of magnitude higher than the overall average DMS (0.0034gday-1AU-1) and DMDS (0.0028gday-1AU-1) emissions. H2S, DMS and DMDS have offensive odors and low odor thresholds. Over all four sampling seasons, 77% of 15min averaged H2S barn concentrations were an order of magnitude above the average odor threshold. During these sampling periods, however, DMS and DMDS concentrations did not exceed their odor thresholds. The overall average barn and lagoon emissions from this study were used to help estimate barn, lagoon and total (barn+lagoon) RSC emissions from swine CAFOs in North Carolina. Total (barn+lagoon) H2S emissions from swine CAFOs in North Carolina were estimated to be 1.22*106kgyr-1. The barns had significantly higher H2S emissions than the lagoons, contributing ≈98% of total North Carolina H2S swine CAFO emissions. Total (barn+lagoon) emissions for DMS and DMDS were 1-2 orders of magnitude lower, with barns contributing ≈86% and ≈93% of total emissions, respectively. H2S swine CAFO emissions were estimated to contribute ≈18% of North Carolina H2S emissions. © 2014 Elsevier Ltd. Citation statistics:
