Measurement of carbon monoxide concentration levels within an underground parking lot throughout the day
Villanueva, J. (2020). Measurement of carbon monoxide concentration levels within an underground parking lot throughout the day. Bcit Environmental Health Journal.
Background: During the fall and winter months, people opt to using cars as a mode of transportation to and from work, school, or recreation. The ease of access, comfort, and efficiency of travel prompt an increase in drivers. Underground lots are ideal parking spaces during these months, which see an increase in traffic and subsequent rise in emissions, specifically carbon monoxide (CO) that can be hazardous to health at certain concentrations. This study is to determine the levels of CO in a confined parking space
Methods: Air quality and composition were determined via passive dosi-tubes that were affixed onto columns within the Langara College underground parking lot in the morning and picked up for analysis in the afternoon.
Results: There is an increase in carbon monoxide concentration within the underground parking lot, during peak hours. Traffic within the lot is found to be higher during poor weather conditions which correlate with ease of use and comfort of driving a car. There is also an increase in traffic on Tuesdays and Thursdays, which is likely dictated by class times. Carbon monoxide levels did not fail to meet government regulations during any sampling period.
Conclusions: The air composition in the Langara underground parking lot is safe even during periods of high traffic, for the average person. However, individuals with underlying medical conditions should enter with caution, as the recorded CO levels can aggravate pre-existing cardio-pulmonary diseases., Peer reviewed, Peer-reviewed article, Published, Project submitted in partial fulfillment of the requirement for the degree of Bachelor of Technology in Environmental Health, British Columbia Institute of Technology 2020., Langara College, Carbon monoxide, Underground parking, Dosi-tube, Car exhaust, Car emissions, Cardio-pulmonary disease
