AbstractIn this research, we evaluated the personal exposure level to fine particulate matter PM2.5 from high traffic roads in the city of Barranquilla. Therefore, we followed the methodology proposed by the U.S. EPA for risk assessment, which consists of the following steps: (1) hazard identification, (2) dose-response assessment, (3) exposure assessment and (4) risk characterization. To develop this study, three strategic monitoring stations were selected on roads with high traffic from the city of Barranquilla, such as: Carrera 45 with Calle 39 (Centro), Carrera 46 with Calle 90 (Autónoma) and Carrera 43 with Calle 72 (Calle 72). Likewise, a green space was contemplated as a monitoring station for the study, which is the Parque Jardín Botánico. Two monitoring campaigns (one business day and one weekend day) were performed for each monitoring station. Two personal air sampling pumps TUFF™ standard model from Casella were used with polyurethane foam filters and 37 mm polytetrafluoroethylene (PTFE) filters to remove coarse particles from fine, respectively. The maximum concentration value for personal exposure was obtained at the monitoring station Calle 72 with a result of 238.10 µg/m3 on the business day, while the minimum result reported was at the monitoring station Jardín Botánico with a value of 59.52 µg/m3 for the weekend day. According to ANOVA hierarchical, it was determined that there are not statistically significant difference between the mean doses of men and women nor the sampling stations. However, there are statistically significant difference between the mean of the two types of days. With regard to the carcinogenic risk, it was determined that people who work near the Calle 72 monitoring station are the ones more likely to develop lung cancer. Simultaneously, in the non-carcinogenic risk, men who work near Calle 72, Autónoma y Centro monitoring stations exceed the permissible exposure limit.
