Objectives: to quantify the contributions of working activities to the total CO exposure of traffic policemen during the work shift and to assess exposure during different periods of the day.Methods: The exposure of 130 traffic wardens working in the city of Milan was assessed in 4 seasonal campaigns performed in 8 of the 15 city headquarters (2 shifts per day). CO concentrations were continuously measured in the breathing zone by passive analyzers programmed with a sampling frequency of 1 min. A time-activity diary with a 20-min time resolution was manually completed by subjects. Details on indoor or outdoor environments, job activities (traffic warding at crossings, surveillance near schools or crossroads, fining in parking zones, drawing up minutes at office), movements (on foot or by means of transport) and smoking (n° cigarettes) were collected. Results: On average, the highest personal exposure to CO was found in the autumnal and winter sessions. The highest median personal exposure to CO was reached in the early morning (08.00-08.59) and late afternoon (18.00-18.59), while start and end of work shifts corresponded to the lowest levels of exposure to CO. Among smokers, weak positive correlations were found between personal exposure to CO and number of cigarettes smoked during the work shift. The occupational activities that occupied most of working time were traffic guarding and time spent in office. Traffic guarding, characterized by a mean CO concentration of 3.50 ppm, produced the highest cumulative exposure to CO,compared with a mean value of 2.41 ppm measured during office activities. Conclusion: As expected, some occupational activities affected the exposure to CO of traffic wardens owing to the proximity to the emission sources. The exposure to CO was also related to automotive traffic density, which produced the highest personal concentrations in the early morning and late afternoon

Abstract

Objectives: to quantify the contributions of working activities to the total CO exposure of traffic policemen during the work shift and to assess exposure during different periods of the day.Methods: The exposure of 130 traffic wardens working in the city of Milan was assessed in 4 seasonal campaigns performed in 8 of the 15 city headquarters (2 shifts per day). CO concentrations were continuously measured in the breathing zone by passive analyzers programmed with a sampling frequency of 1 min. A time-activity diary with a 20-min time resolution was manually completed by subjects. Details on indoor or outdoor environments, job activities (traffic warding at crossings, surveillance near schools or crossroads, fining in parking zones, drawing up minutes at office), movements (on foot or by means of transport) and smoking (n° cigarettes) were collected. Results: On average, the highest personal exposure to CO was found in the autumnal and winter sessions. The highest median personal exposure to CO was reached in the early morning (08.00-08.59) and late afternoon (18.00-18.59), while start and end of work shifts corresponded to the lowest levels of exposure to CO. Among smokers, weak positive correlations were found between personal exposure to CO and number of cigarettes smoked during the work shift. The occupational activities that occupied most of working time were traffic guarding and time spent in office. Traffic guarding, characterized by a mean CO concentration of 3.50 ppm, produced the highest cumulative exposure to CO,compared with a mean value of 2.41 ppm measured during office activities. Conclusion: As expected, some occupational activities affected the exposure to CO of traffic wardens owing to the proximity to the emission sources. The exposure to CO was also related to automotive traffic density, which produced the highest personal concentrations in the early morning and late afternoon
