“…Similarly, Redwine et al (2002) had also reported age enhanced PM and ammonia emissions. The present study also demonstrated that activities in controlled environment facilities result in higher concentration of dust as also reported by Lim et al (2003), Vucemilo et al (2007), Li et al (2009), Calvet et al (2009) and Shen et al (2019) and that the airborne dust in poultry houses increased with the age and activity of birds.…”

“…Herron et al (2015) also reported poultry facilities were found as more contaminated sites as compared to other livestock units (cow and swine farms). The poultry facilities were also rich in organic dust and may cause various health problems (Donham et al 2000;Portejoie et al 2002;Donham et al 2002;Kocaman et al 2005;Oppliger et al 2008;Skora et al 2016;Li et al 2019;Shen et al 2019). Enforcement of the existing occupational health and safety laws (for example, the use of PPE) and good management practices can significantly reduce the risk of exposure to poultry workers.…”

Particulate and gaseous emissions from intensive poultry facilities are major public and environmental health concern. The present study was aimed at exploratory monitoring of particulate matter (PM) and gaseous concentrations in controlled-environment facilities using low-cost sensors in Lahore, Pakistan. The indoors and outdoors of 18 broiler houses, grouped into three categories based on the age of birds: group I (1-20 days), group II (21-30 days) group III (31-40 days) were examined. Low-cost sensors Dylos 1700 and Aeroquals 500 series with different gas sensor heads were used to monitor PM and different gases such as nitrogen dioxide (NO2), hydrogen sulphide (H2S), carbon dioxide (CO2) and methane (CH4) respectively. Overall, the mean PM and gaseous concentrations increased with the age and activity of birds as compared with the non-activity time of birds. Statistically significant differences were observed in all measured parameters among the groups. The negative correlation between indoor and outdoor environments for PM and gas concentrations at some broiler houses demonstrates the contribution of additional sources to emissions in outdoor environments. The findings contribute to our knowledge of temporal characteristics of particulate and gaseous concentrations from poultry facilities particularly in Pakistan and generally to the capability of using low-cost sensors to evaluate emissions from such facilities.

“…From such buildings housing animals at high densities, particulate matter (PM), which is a major air pollutant, is emitted and adversely affects human and animal respiratory health [ 2 , 3 ]. PM from pig houses comprises feces, feedstuff, hair, bedding particles, and animal skin, where feces and feeds occur as smaller particles than biological structures such as animal skin and hair [ 4 ], and feedstuff accounts for a considerable proportion in PM [ 5 ]. Airborne PM can lead to increased prevalence of respiratory diseases such as asthma [ 6 ] and chronic obstructive pulmonary disease [ 7 ] in humans.…”

“…The concentrations of PM in nursery pig houses varied in some studies. Shen et al [24] reported that the concentrations of TSP, PM 10 and PM 2.5 inside were 0.635, 0.388 and 0.210 mg/m 3 , respectively. Kwon et al [25] reported that the concentration of TSP and PM 10 was 1.5 mg/m 3 and 1 mg/m 3 , respectively.…”

Abstract Background: The particulate matter (PM) is a carrier of many substances. Microorganisms are vital constituents contained in PM and the kinds and concentration are closely connected to human health and animal production. This study was aimed to investigate the distribution characteristics of microbial aerosols inside the pig house and as well as in the respiratory tract of pigs. The environment inside a nursery pig house was monitored in winter, including temperature, relative humidity, TSP, PM10, PM2.5, NH3, CO2, CO and NO. The concentrations of airborne culturable bacteria, fungi and Escherichia coli were detected. Then 16 S rRNA sequencing technology was applied to identify bacteria contained in different sized PM and the bacteria in the respiratory tract of piglets.Results: The results showed that the concentration of airborne culturable bacteria inside the pig house was significantly higher than that outside. The concentration of airborne culturable bacteria was reduced with the decrease of the size of PM; the concentration of airborne culturable fungi was mostly distributed in the size of 2.1-3.3 μm and 1.1-2.1 μm PM; most airborne culturable Escherichia coli were distributed in the size of >7.0 μm and 2.1-3.3 μm. Besides, these three types of microbial aerosols did not exhibit significant change during different time points. The 16 S rRNA results showed that the bacteria contained in PM had high similarity with that in the respiratory tract of pigs. The bacteria assemblage in the size of 1.1-3.3 μm PM had high similarity with that in the lower respiratory tract (bronchus and lung) of pigs. In addition, four potential pathogenic bacteria genera (Escherichia-Shigella, Streptococcus, Acinetobacter, Pseudomonas) were identified in the PM samples and the respiratory tract.Conclusions: These results will provide a significant scientific basis in exploring the potential risk of aerosol from animal houses for human and animal health.
