“…These elements were similar to those reported by Aarnink et al (2004) and Schneider et al (2001) in airborne PM in pigs, and by Cambra-López et al (2011b) in poultry, except for certain elements such as Ca (found in a greater extent in this study) and only small amounts of P. The higher content of Ca could be attributable to the use of calcium superphosphate powder in fattening rabbit farm.…”

Livestock houses are major sources of airborne particulate matter (PM), which can originate from manure, feed, feathers, skin and bedding and may contain and transport microorganisms. Improved knowledge of particle size, morphology, chemical and microbiological composition of PM in livestock houses can help identify major sources of PM and contribute to the development of appropriate sourcespecific reduction techniques. In rabbit production systems, however, there is limited information on specific particle characteristics. The objective of this study was to characterise airborne PM in rabbit farms in terms of morphology, chemical compositions and bacterial concentration in different size fractions. Size-fractioned PM was sampled in the air of 2 rabbit farms, 1 for fattening rabbits and 1 for reproductive does, using a virtual cascade impactor, which simultaneously collected total suspended PM (TSP), PM10 and PM2.5 size fractions. Airborne PM samples were examined by light microscopy and scanning electron microscopy combined with energy dispersive X-ray analysis. Representative samples from potential sources of PM were also collected and examined. Additionally, a methodology to extract bacteria from the collected samples of airborne PM was developed to determine the bacterial concentration per PM size fraction. Results showed that airborne PM in rabbit farms is highly complex in particle morphology, especially in size. Broken skin flakes, disintegrated particles from feed or faecal material from mechanical fracture are the main sources of airborne PM in rabbit farms. Major elements found in rabbit airborne PM were S, Ca, Mg, Na and Cl. Bacterial concentrations ranged from 1.7×10 4 to 1.6×10 6 colony forming units (CFU)/m 3 (TSP); from 3.6×10 3 to 3.0×10 4 CFU/m 3 (PM10); and from 3.1×10 3 to 1.6×10 4 CFU/m 3 (PM2.5). Our results will improve the knowledge on essential particle characteristics necessary to understand PM's origin in rabbit farms and contribute to its reduction.

“…In broilers and fattening pigs using bulk analysis, higher levels of N and P in fecal particles compared with skin and feed, and higher levels of N, K, Cl in skin compared with fecal particles and feed were identified . The strong presence of P in airborne particles from manure was also reported by Schneider et al (2001). indicated that particles from fecal origin had higher K than particles from feed.…”

“…These compounds do not only affect human respiratory health, but also animal welfare and productivity through induced disease manifestation and increased mortality (Donham, 1991). Particles from livestock houses can contain a great number of substances such as heavy metals, VOCs, NO 3 -, and SO 4 2-which can be found adhered to the surface of particles (Martin et al, 2008;Schneider et al, 2001). Particulate matter can also adsorb irritant gases, especially NH 3 (Lee and Zhang, 2006;Takai et al, 2002), and odorous compounds Razote et al, 2004).…”

“…These PSDs can furthermore change in time. Mean particle size increased with bird age in broilers (Yoder and Van Wicklen, 1988 Most PSDs of livestock PM are reported as bi-modal (Schneider et al, 2001;Schneider et al, 2006). This bi-modal distribution can partially be explained because emissions of primary particles fall into the coarse mode, whereas emissions of secondary particles fall into the accumulation mode.…”

“…This bi-modal distribution can partially be explained because emissions of primary particles fall into the coarse mode, whereas emissions of secondary particles fall into the accumulation mode. Primary organic particles, however, have also been identified in the accumulation mode, together with secondary sulphate background PM in livestock houses (Schneider et al, 2001 (Schneider et al, 2006).…”

High ambient concentrations of PM can threaten human and animal health and welfare, as well as the environment. The best approach to reduce PM emissions from livestock houses seems to be to prevent it from being generated. Controlling PM at source not only reduces emissions but also improves inside air quality. Furthermore, data on particle morphology...
