Evaluation of carbon monoxide and carbon dioxide concentrations using a factorial design in the main urban parks of Pereira.
This study presents a factorial design conducted in the main parks of Pereira, aimed at analyzing air quality and the atmospheric pollutant load in public spaces with high vehicular and pedestrian traffic. It considers the impact of population exposure to common air pollutants such as carbon monoxide (CO) and carbon dioxide (CO₂). A factorial design was employed to evaluate the effects of key independent variables—including time of day, day of the week, and proximity to vehicular sources—on the concentration levels of these gases across five major parks in the city.
Measurements were performed using calibrated portable sensors under controlled sampling conditions during strategically selected time slots characterized by high traffic flow and large gatherings of people on weekdays. The results revealed significant variations in CO and CO₂ concentrations, with notably higher levels during peak hours in the city's central parks.
This research provides critical data to support decision-making processes aimed at designing public policies that promote healthier urban environments. It also highlights the value of experimental design as a robust methodological tool for environmental assessment. The study concludes that continuous monitoring and the implementation of targeted mitigation strategies are essential to reducing public exposure to atmospheric pollutants.
