- Abstract: 

        Ultrafine particles (UFPs) and black carbon (BC) are two types of traffic-related air pollutants (TRAPs) which can cause adverse health effects and regulate climate due to their unique characteristics in the atmosphere. Despite the recent worldwide interests, many uncertainties still remain related to their distributions, interactions, and potential health effects. This study investigated spatiotemporal characteristics of TRAPs UFPs & BC in industrial and residential roadside of Zhongli Industrial Park. Furthermore, effects of potential confounding factors and exposure risks of these pollutants were also discussed in this study. Results from seasonal measurement activities showed that these pollutants exhibited seasonal variations where mean concentrations of UFPs and BC in industrial roadside could increase up to 16.06% and 20.35% during cold period. Furthermore, it was found that traffic activities, specifically vehicles flux and composition including (heavy, gasoline, motorcycle) were significantly correlated (r ≥ 0.60) with UFPs PNC and BC. Meteorological factors namely temperature, WD, and RH were mildly significant towards UFPs PNC and BC. Initial exposure risk assessment results showed that current averages of UFPs PNC and BC concentrations in roadside area of Zhongli industrial park were substantially higher than recommended level of <2 x 104 #/cm3 & <1.1 ng/m3 proposed by WHO global air quality guideline.
