Workers who perform the hazelnuts operations of mechanized harvesting are exposed to the harmful effects of inhalation of dust that is raised by machinery. This paper aims to point out the possibility of reducing the dust, including respirable dust, emitted into the atmosphere during mechanical harvesting of hazelnuts by use of a new device developed at the Tuscia University installed on harvesters. The effectiveness of the system was evaluated by sampling the dust released into the environment (environmental sampling) and dust that concerns the driver (personal sampling). The results reveal that the dust concentration decreases significantly by using the suction machine equipped with the device for the reduction of dust compared to the standard suction machine. The ability to reduce the dust is greater than 70% in the case of sampling in ambient air, and over 60% in the sampling operator. Future developments in the work include the determination of free crystalline silica (SLC), which can be a risk factor for the workers of the sector and for the people living in area’s cultivation of the hazelnut.
