Respiratory diseases are frequent in tunnel construction workers. A group of 144 subjects randomly selected from the population of 2516 workers engaged in the construction of the railway tunnel under the Appennine Mountains, from Bologna to Firenze was investigated. A group of 69 males comparable for age, living area and habits was studied as a control group. Assessment of air pollutants (NO, NO2, SO2, total dust, silica %) was carried out by means of fixed monitoring stations as well as personal monitors. All the subjects included in the study were examined with a standardised protocol which included physical examination, lung function tests (before and after shift work) and a questionnaire to college respiratory symptoms. Low concentrations of environmental pollutants were evidenced. Significantly lower values of FEV1 and PEF were determined in the worker group pared to controls. A significant decrease in respiratory parameters was shown after shift work. Variables capable of influencing the decrease in parameters include smoking habits, work activity, presence of cough and expectoration, period of the year (spirometries resulted worse in the winter time). Significantly lower values of FEV1 and PEF were evidenced in the workers compared to controls. In spite of the present low work environmental exposure conditions, some physiologic parameters appear altered in tunnel construction workers. This may depend on a variety of noxious agents present in the working environment.

Abstract
Respiratory diseases are frequent in tunnel construction workers. A group of 144 subjects randomly selected from the population of 2516 workers engaged in the construction of the railway tunnel under the Appennine Mountains, from Bologna to Firenze was investigated. A group of 69 males comparable for age, living area and habits was studied as a control group. Assessment of air pollutants (NO, NO2, SO2, total dust, silica %) was carried out by means of fixed monitoring stations as well as personal monitors. All the subjects included in the study were examined with a standardised protocol which included physical examination, lung function tests (before and after shift work) and a questionnaire to college respiratory symptoms. Low concentrations of environmental pollutants were evidenced. Significantly lower values of FEV1 and PEF were determined in the worker group pared to controls. A significant decrease in respiratory parameters was shown after shift work. Variables capable of influencing the decrease in parameters include smoking habits, work activity, presence of cough and expectoration, period of the year (spirometries resulted worse in the winter time). Significantly lower values of FEV1 and PEF were evidenced in the workers compared to controls. In spite of the present low work environmental exposure conditions, some physiologic parameters appear altered in tunnel construction workers. This may depend on a variety of noxious agents present in the working environment.File | Dimensione | Formato | |
