“…This result can be explained by the fact that the birds moulted around this time, causing an increase in dust. Furthermore, the enhanced ventilation caused by the warmer temperatures aided in dust extraction from the unit (Mostafa, 2012). The present results in agreement with Yahav et al, (2001) who documented that the dust concentration was mostly influenced by relative humidity and temperature.…”

“…With rising temperatures, the average rate of dust emission increased, which can be explained by increased poultry moulting. Furthermore, enhanced ventilation combined with high temperatures aided in the extraction of dust from the farm (Mostafa, 2012). Low relative humidity has resulted in higher dust concentrations in the environment, posing a health risk to animals and employees (Yahav et al, 2001).…”

The atmosphere of poultry farms usually contains significant levels of agricultural dust and toxic gases, which may cause harm to workers' health. Therefore, this study was conducted to investigate the environmental exposure to dust pollutants; inhalable (PM 10 ) and respirable (PM 2.5 ) dust. The study was carried out in 4 commercially operated poultry farms located in Al-Dakahlia Governorate, Egypt. The chosen poultry farms were based on their equipped way. The air samples were collected twice a week during 3 different stages of the rearing period of broiler chicks. The study was done during the period of November 2018 to April 2019. The results of this study showed that inhalable dust varied between 99 -215 µg/m3 and respirable dust varied from 83-195 µg/m3 in farms C and D, respectively. It can be concluded the accumulation of manure, water, and feed remains lead to several pollutants particulate matters which have hazard health effects on farmworkers. Therefore, personal protective equipment as a face mask and mask filter must be used especially during disinfection process, for reduction of the pollutants exposure.

“…However, the PM concentration in broiler houses is higher than that in laying houses ( Cambra-López et al, 2010 ). The primary sources of PM from poultry houses are feeds, feathers, manure, urine mineral crystals, and so on ( Mostafa, 2012 ). Activities of workers and broilers, such as sweep, flapping of wings, and coughing, can cause the production of PM 2.5 , which can stay in the air for a long time.…”

Fine particulate matter ( PM 2.5 ) from poultry houses has adverse effects on the health of animals and workers. Tert-butylhydroquinone ( TBHQ ), an antioxidant, is widely used in feed additives. The present study investigated the effects of TBHQ on broiler house PM 2.5 -induced damage in chicken primary alveolar epithelial cells ( AECII ) extracted from 16-day-old chicken embryos using the method of differential adhesion. AECII were exposed to PM 2.5 and TBHQ alone or in combination, and then, cell membrane integrity, pyroptosis, and necroptosis were detected. Our results showed that PM 2.5 from broiler houses caused cell rupture and loss of cell membrane integrity. This result was confirmed by the obvious increases in lactate dehydrogenase ( LDH ) release and propidium iodide ( PI )-positive cells compared to the control group. In addition, the intracellular reactive oxygen species ( ROS) levels and the expression levels of pyroptosis-related genes ( NLRP3, IL-18, IL-1β ) and necroptosis-related genes ( RIPK3 ) were also significantly enhanced. However, TBHQ significantly inhibited intracellular ROS, improved cell viability, and reduced the release of LDH and the number of PI-positive cells compared to those in the PM 2.5 group. The expression levels of pyroptosis-related genes ( Caspase-1, NLRP3, IL-18, IL-1β ) and necroptosis-related genes ( RIPK3 ) were also significantly decreased in the co-treatment group. In summary, these results indicated that TBHQ can alleviate PM 2.5 -mediated cell pyroptosis and necroptosis in chicken AECII and provide a basis for overcoming the danger that air pollutants from broiler houses pose to the health of chickens.

This study aimed to investigate dust and bacterial air contamination in a broiler house during different seasons. The study was carried out in commercial housing conditions during five weeks of the rearing cycle in summer and winter. The total dust concentration ranged from 1.90 to 4.50 mg/m3 in summer and from 2.80 to 5.10 mg/m3 in winter. The total bacterial count ranged from 2.85 × 104 to 1.03 × 105 CFU/m3 in summer and from 2.12 × 104 to 2.28 × 105 CFU/m3 in winter. The study results showed the dust concentration to be increased in winter as compared to summer, yielding a significant correlation (r = 0.602, p < 0.05) with a significantly higher airborne bacterial count in winter (p < 0.001). Furthermore, dust concentration showed significant correlations (p < 0.05) with air temperature (r = −0.418), relative humidity (r = 0.673), and broiler activity (r = 0.709), while bacterial count yielded significant correlations (p < 0.05) with air temperature (r = −0.756), relative humidity (r = 0.831), and airflow rate (r = 0.511). The results obtained in the study can prove useful in the field. Seasonal variability in dust and bacterial air contamination should be considered in the development of guidelines or standards of air quality in broiler housing and evaluation of the effectiveness of remedial strategies.
