This study was conducted to investigate the environmental exposure to dust pollutants; inhalable (PM10) and respirable (PM2.5) dust. The measurements were carried out in 4 commercially operated poultry farms located in Al-Dakahlia Governorate, Egypt. All investigated poultry farms differentiated in how to be equipped. The air samples were collected during 3 different stages of the rearing period of broiler chicks twice a week, from 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 farm C and farm D, respectively. It can be concluded the accumulation of the manure, water and feed remains lead to several pollutants particulate matters which has hazard health effects on farm workers. Therefore, the personal protective equipment as face mask and mask filter must be used, especially during disinfection for reduction of the pollutants exposure.
