“…Environmental exposure is a critical aspect and several studies evidenced that different outdoor, indoor, rural, and urban environments may contribute to determine or exacerbate the health effects [12][13][14]. In this regard a key role should be attributed to occupational settings that may increase pre-existing sensitization and/or respiratory pathologies due to other biological, chemical and physical agents mainly present in workplaces.…”

“…Many epidemiological and research studies in the literature have focused on potential interactions between chemical pollutants (e.g., ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide), particulate matter including PM 10 , PM 2,5 and airborne particles, showing the relevant effects of air pollutants on bioaerosol properties [13,14,[28][29][30][31].…”

“…In this regard, important alterations have been reported in the biological and reproduction functions of pollen (e.g., decrease in pollen germination and survival) and modifications of pollen surface characteristics, and in addition pollutants seem to act as adjuvants to pollen allergens enhancing their potential health risks [13,14,[28][29][30]. Prominent studies have shown that air pollutants might adhere on pollen surface damaging pollen cell membranes, with a significant number of allergens released into the environment [14,32,33].…”

“…In addition to air pollutants and meteorological factors, several papers have evidenced the effect of urbanization on plant reproduction (e.g., earlier pollen flowering), pollen abundance (e.g., overexpression of allergenic proteins), pollen dispersion, people's exposure to allergens, and severity of allergic diseases/symptoms. Furthermore, associations between urbanization and the rising prevalence of allergic epidemics in urban areas compared to those in rural environments have been studied [13,14,34,35]. However, the pollen count pattern in urban and rural areas is also linked to many critical aspects such as size of vegetation areas, distance to pollen source in relation to pollen transport and dispersal, and presence of ornamental vegetation.…”

Pollen exposure in occupational settings involves different categories of workers. In this paper the effects of diurnal pollen variations have been evaluated in two sites characterized by different vegetation and urbanization: the suburban site of Tor Vergata (TV) and the rural site of Monte Porzio Catone (MPC). Aerobiological and meteorological monitoring was performed in the two sites during the winter of 2017. The data analysis focuses on the comparison between pollen concentrations observed in relation to meteorological variables. In general, it can be stated that the indoor and outdoor dynamics for MPC and TV are different, with the outdoor concentration of pollen for MPC always higher than for TV, in accordance with significant presence of vegetation. The high nocturnal peaks detected in MPC and completely absent in TV could be caused by the presence of particular conditions of stagnation combined with greater emissions from the pollen sources. Furthermore the higher I/O ratio observed during the working hours in TV compared to MPC could be ascribed to the workers’ behavior. Exposure to pollen can be responsible for several health effects and the knowledge of its level can be useful to improve the evaluation and management of this biological risk.

“…in geographical regions where they have not been resident before. The early and prolonged blooming season due to increased temperature leads to higher and prolonged allergen exposure for patients, and allergenicity of molecules becomes more potent in combination with CO 2, 11 ozone, 12 or pollution contributing fine‐ and ultra‐fine particles 13 …”
