Abstract
Taipei City is a metropolis with dense population and heavy traffic. Traffic policemen
always play an important role of giving guidance for traffic, so that they have a high risk
with exposure of air pollutants emitted from motor vehicles. Until recently, most studies of
exposure assessment for traffic police were focused on carbon monoxide (CO) and volatile
organic compounds (VOC). Few studies were addressed on evaluation of suspended
particulate matter (including PM2.5 and PM1) and nitrogen dioxide (NO2) exposure in traffic
police. Therefore, this study will investigate air pollutants (including PM10, PM2.5, PM1,
NO2, CO and O3) exposure during work in traffic policemen by using personal sampling
method. Previous studies mainly evaluated pulmonary function for airway health effects in
traffic policemen. However, no study was assessed traffic policemen’ airway inflammation
caused by air pollutants using exhaled breath analysis. Further study will be investigated
the relationship between exposure of air pollutants from motor vehicles emission during
work and airway inflammation in traffic policemen. We, therefore, will propose a
three-year research plan to accomplish anticipated work as below. In year one, the study
will investigate of traffic-related air pollutants exposure in the traffic policemen in district of
Datong in Taipei city, and evaluate the relationship between concentrations of traffic-related
air pollutants measured at the ambient air monitoring site operated by Taiwan Environmental
Protection Agency (EPA) that located in district of Datong and exposure concentrations of
traffic-related air pollutants in traffic policemen. In year two, this study will evaluate the
exhaled nitric oxide, exhaled breath condensate pH, and pulmonary function in traffic
policemen without history of allergy and airway diseases before and after work in four
seasons. In year three, this study will explore the severity of airway inflammation caused
by inhalation of traffic-related air pollutants in traffic policemen with allergic diseases
(asthma and allergic rhinitis) using exhaled gas indicators. In addition, comparison of
exhaled gas indicators (exhaled nitric oxide and exhaled breath condensate pH) before and
after work in four seasons between traffic policemen without history of allergy and airway
diseases and those with allergic diseases will be achieved in the study.
