Characterizing the particle variations and human exposure in port and urban areas

In port areas, traffic is characterized by container trucks which run on diesel, while in urban areas, it is characterized by cars which run on petrol. These areas have different sources of pollution and have distinct particle pollution. In this study, field measurements were carried out to reveal the patterns of pollution from various sources and analyze short-term exposures to pollution in port and urban areas. The presence of particulate matter (PM) is closely related to that of container trucks and cars in port areas and urban areas, respectively. In both types of sampling sites, most PM concentrations can be fitted with a lognormal distribution. Additionally, the results reveal that the number and mass concentrations of PM in the port area are higher than those in the urban area. The human exposure assessments exhibit that fine particles tend to have greater deposition for the port area in the afternoon compared to the urban area, further demonstrating the considerable influence of container truck emissions on human health.
