“…The comparison result was further assessed through thermodynamic simulation. Using experimentally determined particle-to-gas partition coefficients (KPM/air; a dimensionless version of Kp), it was calculated that the total mass fraction of PM-sorbed acetic acid, butanoic acid, dimethyl disulfide, and phenol would not exceed 0.11% of PM mass at 1 mg m -3 PM10 (Walgraeve et al, 2015). The calculated odorant fractions were lower than some field measurement results (Hammond et al, 1981;.…”

“… PM samples of various size fractions, including TSP (Hammond et al, 1981;Razote et al, 2004;Cai et al, 2006;, PM10 (Cai et al, 2006;Walgraeve et al, 2015), PM2.5 (Cai et al, 2006), and PM1 (Cai et al, 2006), were collected for odorant analysis. In many early studies, settled dust was selected as a surrogate for PM (Hammond et al, 1979;Hartung et al, 1985;Donham et al, 1986;Wang et al, 1998;Oehrl et al, 2001;Das et al, 2004;.…”

“… Many odorants occurred at a lower concentration (e.g., µg odorant per m 3 of barn air) in PM than in gaseous forms. Direct comparisons of PM-borne with gaseous odorants showed that most detected odorants existed primarily in the gas phase (Andersen et al, 2014;Walgraeve et al, 2015). The comparison result was further assessed through thermodynamic simulation.…”

“… PM can concentrate and amplify odors. PM carried substantially larger amounts of odorants than the same volume of air (Hammond et al, 1981;Walgraeve et al, 2015). Thus, PM deposited on the olfactory region in the human's nasal cavity will trigger an odor perception equivalent to a much larger volume of air.…”

Particulate matter (PM) represents an air quality management challenge for confined swine production systems. Because of the limited space and ventilation rate, PM can reach relatively high concentrations in swine barns. PM in swine barns possesses different physical, chemical, and biological characteristics than that in the atmosphere and other indoor environments. As a result, it exerts different environmental and health effects and creates some unique challenges regarding PM measurement and mitigation. Numerous research efforts have been made, generating massive data and information. However, relevant review reports are sporadic. This study aims to provide an updated comprehensive review of swine barn PM, focusing on publications since 1990. It covers various topics, including PM characteristics, sources, measurement methods, and in-barn mitigation technologies. Since PM in swine barns is of primarily biological origins, bioaerosols are reviewed in great detail. Relevant topics include bacterial/fungal counts, viruses, microbial community composition, antibiotic-resistant bacteria, antibiotic resistance genes, endotoxins, and (1→3)-β-D-glucans. For each topic, existing knowledge is summarized and discussed and knowledge gaps are identified. Overall, PM in swine barns is complicated in chemical and biological composition and highly variable in mass concentrations, size, and microbial abundance. Feed, feces, and skins constitute the major PM sources. Regarding in-barn PM mitigation, four technologies (oil/water sprinkling, ionization, alternation of feed and feeders, and recirculating air filtration) are dominant. However, none of them have been widely used in commercial barns. A collective discussion of major knowledge gaps and future research needs is offered at the end of the report.

BACKGROUNDBiofiltration is a technique to remove volatile organic compounds (VOCs) from waste gas streams. It can be regarded as a sustainable treatment technology with low operational costs and good performance. The treatment of hydrophobic compounds is however difficult, due to the low mass transfer towards the water phase on top of the biofilm present on the packing material. To overcome this mass transfer limitation, a hydrophobic silicone foam was added to a conventional biofilter containing compost and wood dowels.RESULTSThe biofilter was operated for 180 days to treat acetone, hexane and dimethyl sulphide at an empty bed residence time of 57 s with inlet load varying up to 4.5 g m3 h‐1. The highest removal efficiency of acetone, dimethyl sulphide and hexane was, respectively, 99%, 80% and 50%. The affinity of the target compounds towards the packing material was quantified in terms of the packing material‐to‐air partitioning coefficient, which was measured using a SIFT‐MS based breakthrough approach. These experiments revealed that hexane has a 20 to 100 times higher affinity for silicone foam than compost and wood. Microbial community analysis was performed on the different substituents of the packing material at the inlet and outlet. No significant differences in relative abundance were observed between the types of packing materials. Comparison with literature revealed the presence of bacterial strains that were not yet reported in biofilter studies.CONCLUSIONSilicone foam in a biofiltration set‐up showed good performances against the degradation of the target VOCs and mass transfer to the packing material can be increased. © 2018 Society of Chemical Industry
